Description

Frame sealing system, curtain walling system and method of mounting a curtain wall

A first, separate invention relates to a frame sealing system adapted to mutually position and mutually seal a first frame and a second frame arranged adjacently to each other, each frame surrounding a window or door or other wall element and being provided with a peripherally extending groove, the frame sealing system including a seal carrier profile having a longitudinal direction, an inner face and an outer face, a first side being provided with a first sealing strip adapted to seal against the first frame and a second side being provided with a second sealing strip adapted to seal against the sec- ond frame, and the frame sealing system being adapted to engage the peripherally extending groove of each frame.

EP 3 043 016 Al (VK Holding A/S) discloses a mullion rail for installing frames, windows or doors. The mullion rail may be used between the frame and wall construction and between the frame and frame construction. The mullion rail has slots and matching clips which are separate and insertable into the slots. In the mounted state of the mullion rail, the clips engage a peripheral groove of the window frames or the like in order to mutually position these. The mullion rail furthermore has sealing lips adapted to mutually seal the window frames or the like against each other. The mullion rail may for example be made from a structural polymer, polyvinyl chloride (PVC), or a fiberglass or carbon fibre reinforced composite material. However, if the mullion rail is relatively long, thermal expansion may cause the length of the profile to change relatively much with the temperature which may be unacceptable. WO 2006/042895 Al relates to a facade which is constructed from a series of independent modular elements such as windows mounted frames composed by profile which are already assembled when delivered from the factory to the site, thereby enabling the facade to be quickly mounted. The profiles of adjacent frames may be connected to each other by means of a connection element provided with two spaced rubber sealing strips engaging corresponding grooves in the respective frames. Furthermore, the adjacent frames are fixed to each other by means of screws. However, the assembly of the facade may be rather cumbersome. JP2007218008A discloses an assembly of three window frames arranged in a window opening. A mullion is arranged vertically between two window frames and sealing strips seal against the window frames and form a vertical space for draining water between an outdoor-side part of each vertical frame and an outdoor-side part of the mullion.

US 6,360,498 Bl discloses a two-piece mullion reinforcement for use in forming an assembly of windows. A first member is fastenable to a portion of a first window frame, and includes at least one piloting tab that extends along and projects outwardly from a surface of the first member. A second member is likewise fastenable to a portion of a second window frame, and includes at least one pilot receptacle that is formed on a surface of the second member. The pilot tab and pilot receptacle comprise mutually complementary profiles so as to be engageable with one another when the first window frame is assembled to the second window frame. Preferably, mullion reinforcement members comprise a metal, such as an aluminium alloy or steel, or a combination of aluminium alloy and steel, or may comprise other metals, a structural polymer, or a fibre glass or carbon fibre reinforced composite material of the type well known in the art. Each mullion reinforcement member has a length that is at least similar to the length of inner jambs or outer jambs of the frames. However, if the mullion reinforcement is rela- tively long, depending on the material used, thermal expansion may cause the length of the profile to change relatively much with the temperature which may be unacceptable. On the other hand, depending on the material used, the mullion reinforcement may form a thermal bridge which is undesired. US 8,266,851 B2 discloses a mullion system including a universal reinforcement key that joins window frame members and when anchored in a window frame opening or against other window frame joining members, contributes to bearing the load on the window frame unit. Reinforcement members may be made, for example, from extruded materials such as aluminium, plastic or the like.

US 4,590,725 discloses a system for sealing cross a joint of four adjacent curtain wall units. The sealing system has a packing block of soft elastomeric material mounted at the cross joint between four adjacent curtain wall units. At their one ends, first and second horizontal gaskets, each mounted between the upper and lower curtain wall units, are disposed against opposite sides of the packing block. First interior and exterior vertical gaskets are mounted between the two upper curtain wall units to define a first verti- cal space. The lower end of the first interior vertical gasket is disposed against the top of the packing block, while the lower end of the first exterior vertical gasket is spaced from the top of the packing block to define therebetween a drainage passage through which the vertical space opens to the exterior. Second interior and exterior vertical gaskets are mounted between the two lower curtain wall units to define a second vertical space. The upper ends of the second interior and exterior vertical gaskets are disposed against the bottom of the packing block.

The object of the first invention is to provide a frame sealing system enabling optimization of both sealing and isolation properties as well as positioning properties.

In view of this object, the first side of the seal carrier profile is provided with a first recess in which the first sealing strip is mounted and the second side of the seal carrier profile is provided with a second recess in which the second sealing strip is mounted, each first and second sealing strip is made of a deformable adhesive material adapted to adhere to the respective frame, and the frame sealing system is provided with a first flange adapted to engage the peripherally extending groove of the first frame and a second flange adapted to engage the peripherally extending groove of the second frame. In this way, the sealing and isolation properties of the first and second sealing strips may be optimized independently of the positioning properties of the flanges adapted to engage the peripherally extending groove, and vice versa. The deformable adhesive material may adhere to both the recesses of the seal carrier profile and the respective frames and thereby ensure good sealing properties. The seal carrier profile may be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, if it does not need to carry the load of the forces acting between the frames. These forces may be taken up by the flanges which act to mutually position the frames. The flanges may be produced as strong as necessary with only very little impact on the sealing properties. The flanges may be a part of the seal carrier profiles, they may be connected with or abut the seal carrier profiles or they may be separate elements or a part of separate elements.

In an embodiment, the deformable adhesive material is a rubber adhesive based on natural or synthetic rubbers. Preferably, the deformable adhesive material is an adhesive butyl rubber, sometimes just called "butyl". Adhesive butyl rubber has low temperature-sensitivity and adheres very well to many different materials.

In an alternative embodiment, the deformable adhesive material is an acrylic adhesive.

In an embodiment, each first and second recess has a width and a depth, and, in the unmounted position of the frame sealing system, each of the first and second sealing strips fills its corresponding recess only partly in a direction of the width of the recess and protrudes from the recess, in a direction of the depth of the recess, by a distance corresponding to at least 1/2 of the depth of the recess and preferably corresponding to at least the depth of the recess. Thereby, when the seal carrier profile is mounted on a frame, the deformable adhesive material making up the sealing strip may be deformed in that it is pressed flat so that it is flush with the side of the seal carrier profile in which the corresponding recess is formed, and so that the deformable adhesive material at least substantially fills up the recess and thereby adheres to the frame over at least substantially the entire width of the recess. Thereby, a suitable large contact area between the deforma ble adhesive material and the frame may be ensured, and a suitable contact pressure may be created between the deformable adhesive material and the frame, thereby ensuring good adhesion.

In an embodiment, each of the first and second sealing strips is provided with a release liner to be removed before adhesion to the respective frame. Thereby, it may be avoid- ed that the deformable adhesive material collects dust or particles which could degrade the adhesive properties of the sealing strip. Furthermore, handling of the seal carrier profile may be facilitated in that the adhesive properties of the deformable adhesive material may be released only when the seal carrier profile is correctly positioned. The release liner may prevent that, during handling, the deformable adhesive material adheres to other items than intended. In an embodiment, each first and second recess of the seal carrier profile is spaced from the inner face and opens through the outer face. Thereby, it may be prevented that the deformable adhesive material flows to the inside of the seal carrier profile, but still the deformable adhesive material may be able to expand in the recess when the seal carrier profile is mounted on a frame, and excessive material may escape from the recess through the opening in the outer face.

In an embodiment, the outer face of the seal carrier profile is provided with an elastic gasket adapted to mutually seal the first and second frames against each other and thereby form at least one outer drain channel between said adjacent frames. The elastic gasket may provide a primary seal in front of the seal carrier profile, and any water leaking through said primary seal may be drained away by means of the at least one outer drain channel. Thereby, the risk of any water reaching the seal carrier profile itself may be substantially reduced. Because of the elastic gasket in front of the seal carrier profile, the pressure of any water that does reach the seal carrier profile will be substantially reduced. Because the sealing properties of the seal carrier profile provided with the deformable adhesive material may indeed by very good, the risk of any water entering through both the primary seal in the form of the gasket and the secondary seal in the form of the seal carrier profile may be very little. In an embodiment, the elastic gasket has a first side and a second side separated by a wall of the gasket, the first side of the gasket is provided with a first outer sealing lip and a first inner sealing lip spaced from each other and both adapted to seal against the first frame to form a first drain channel, and the second side of the gasket is provided with a second outer sealing lip and a second inner sealing lip spaced from each other and both adapted to seal against the second frame to form a second drain channel. Thereby, the gasket may create a double sealing effect in that both the outer sealing lips and the inner sealing lips seal against the respective frames. Furthermore, because the gasket forms a first drain channel and a second drain channel which are separated from each other by means of the wall of the gasket, an even better sealing effect may be obtained. In this way, any water possibly reaching one of the first or the second drain channels may immediately be drained away without reaching the opposed frame. Thereby, the risk that any water having reached one of the drain channels could leak into the building is further reduced.

In an embodiment, the frame sealing system includes at least two locator blocks adapted to abut the seal carrier profile so that the locator blocks are spaced in the longi- tudinal direction of the seal carrier profile, and each locator block has a first side being provided with a first flange adapted to engage the peripherally extending groove of the first frame and a second side being provided with a second flange adapted to engage the peripherally extending groove of the second frame. Thereby, because the locator blocks are separate elements, which abut the seal carrier profile, the sealing and isolation properties of the continuous seal carrier profile may be optimized independently of the positioning properties of the locator blocks, and vice versa. The seal carrier profile can be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, because it does not need to carry the load of the forces acting between the frames. These forces may be taken up by the locator blocks which act to mutually position the frames. The locator blocks, in turn, may be produced as strong as necessary with only very little impact on the sealing properties. Furthermore, the locator blocks may facilitate positioning of the seal carrier profile on the respective frames, because the position of the locator blocks is given by the peripherally extending groove, and the seal carrier profile may be brought into abutment with the locator blocks during positioning.

In an embodiment, the seal carrier profile is made of a first material having a first coefficient of thermal expansion and the locator block is made of a second material having a second coefficient of thermal expansion, and the second coefficient of thermal expan- sion is greater than or substantially greater than the first coefficient of thermal expansion. Because the seal carrier profile extends continuously along frame members of the frames, the seal carrier profile may preferably be made from a material having a rela- tively low coefficient of thermal expansion, such as wood. As a result, the length of the seal carrier profiles will only change relatively little as a result of temperature changes and therefore, the change in length may easily be taken up for instance by means of an end gasket. Consequently, very good sealing properties may be achieved.

Because the locator blocks are separate, discretely arranged elements, which the seal carrier profile only abuts, the material of these may be chosen without taking into consideration the coefficient of thermal expansion, that is, a greater coefficient of thermal expansion may be accepted. Consequently, a strong material such as plastic may be used. In any case, in order to not create a thermal bridge, a material having low thermal conductivity may be preferred for the locator blocks.

In an embodiment, the first side of the seal carrier profile is provided with the first flange adapted to engage the peripherally extending groove of the first frame and the second side of the seal carrier profile is provided with the second flange adapted to engage the peripherally extending groove of the second frame. Thereby, mounting of the sealing system may be facilitated in that the seal carrier profile and the first and second flanges may be mounted in one operation. In an embodiment, the first side of each locator block is provided with at least one elastic gripper adapted to abut a first side wall of the peripherally extending groove of the first frame. Thereby, when the locator block has been positioned on the first frame with its first flange engaging the peripherally extending groove of the first frame, the elastic gripper may ensure that the locator block does not move when the seal carrier profile is subsequently brought into abutment with the locator block and mounted on the first frame, and when the second frame is positioned adjacent the first frame and the second flange of the locator block is brought into engagement with the peripherally extending groove of the second frame. In a structurally particularly advantageous embodiment, the at least one elastic gripper of each locator block is arranged between two spaced flanges forming the first flange of the locator block. In an embodiment, a curtain walling system includes a number of frames arranged adjacently to each other and forming a wall or a part of a wall having an outside and an inside, the frames being arranged in at least two horizontally extending rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, wherein adjacent frames are sealed against each other by means of a frame sealing system as described above. In an embodiment, a curtain walling system includes a number of frames arranged adjacently to each other and forming a wall or a part of a wall having an outside and an inside, the frames being arranged in at least two horizontally extending rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, wherein adjacent frames are sealed against each other by means of a frame sealing system including a seal carrier profile having a longitudinal direction, a first side being provided with a first sealing strip sealing against a first frame and a second side being provided with a second sealing strip sealing against a second frame, and the frame sealing system engaging a peripherally extending groove of each frame.

The curtain walling system is characterised in that the first side of the seal carrier profile is provided with a first recess in which the first sealing strip is arranged and the second side of the seal carrier profile is provided with a second recess in which the second seal- ing strip is arranged, in that each first and second sealing strip is made of a deformable adhesive material adhering to the respective frame, and in that the frame sealing system is provided with a first flange engaging the peripherally extending groove of the first frame and a second flange engaging the peripherally extending groove of the second frame.

A second, separate invention relates to a curtain walling system including a number of frames arranged adjacently to each other and forming a wall or a part of a wall having an outside and an inside, the frames being arranged in at least two horizontally extending rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, wherein adjacent frames are sealed against each other by means of a frame sealing system including a seal carrier profile having a longitudinal direction, a first side being provided with a first sealing strip sealing against a first frame and a second side being provided with a second sealing strip sealing against a second frame, and the frame sealing system engaging a peripherally extending groove of each frame.

The object of this second invention is to provide a curtain walling system being easy to install and having improved isolation properties.

In view of this object, the frame sealing system includes a number of locator blocks spaced in the longitudinal direction of the seal carrier profile, and in that each locator block has a first side being provided with a first flange engaging the peripherally extending groove of the first frame and a second side being provided with a second flange engaging the peripherally extending groove of the second frame. In this way, because the locator blocks are separate elements, the sealing and isolation properties of the continuous seal carrier profile may be optimized independently of the installation and positioning properties of the locator blocks, and vice versa. The seal carrier profile can be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, because it does not need to carry the load of the forces acting between the frames. These forces may be taken up by the locator blocks which act to mutually position the frames. The locator blocks, in turn, may be produced as strong as necessary with only very little impact on the sealing properties, because the locator blocks are separate elements that does not extend continuously along the seal carrier profile.

In an embodiment, each horizontally extending seal carrier profile arranged between two horizontally extending rows of frames positioned on top of each other is formed by one or more profiles arranged end to end, preferably via a sealing strip, thereby forming a through going horizontal seal carrier profile extending from side to side of the curtain walling system, and each vertically extending seal carrier profile arranged between two adjacent frames has a length corresponding at least approximately to the height of said adjacent frames and abuts, preferably via a sealing strip, any horizontally extending seal carrier profile arranged just above and/or just below said vertically extending seal carrier profile. Thereby, tolerances of a horizontally extending row of frames may be eliminated by the arrangement of a through going horizontal seal carrier profile on top of said horizontally extending row of frames, thereby avoiding that such tolerances accu- mulate from bottom to top of the curtain wall. If the through going horizontal seal carrier profile is not level due to tolerances, the positioning of the profile may be corrected by means of wedges or the like which are inserted below the profile before the next row of frames is installed on top of the profile.

In an embodiment, the locator blocks abut the seal carrier profile. Thereby, during installation of the curtain wall, the locator blocks may facilitate positioning of the seal carrier profile on the respective frames, because the position of the locator blocks is given by the peripherally extending groove, and the seal carrier profile may be brought into abutment with the locator blocks during positioning.

In an embodiment, corresponding seal carrier profiles are arranged on opposed sides of the locator blocks. Thereby, further improved sealing properties may be achieved.

In an embodiment, the first side of the seal carrier profile is provided with a first recess in which the first sealing strip is arranged and the second side of the seal carrier profile is provided with a second recess in which the second sealing strip is arranged, and each first and second sealing strip is made of a deformable adhesive material adhering to the respective frame. Thereby, the sealing and isolation properties of the first and second sealing strips may be optimized independently of the positioning properties of the flanges adapted to engage the peripherally extending groove, and vice versa. The deformable adhesive material may adhere to both the recesses of the seal carrier profile and the respective frames and thereby ensure good sealing properties. The seal carrier profile may be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, because it does not need to carry the load of the forces acting between the frames. These forces may be taken up by the locator blocks which act to mutually position the frames. The locator blocks may be pro- duced as strong as necessary with only very little impact on the sealing properties.

In an embodiment, the first side of the seal carrier profile abuts the first frame and the second side of the seal carrier profile abuts the second frame. Thereby, a fixed position of the seal carrier profile may be ensured due to friction between the seal carrier profile and the frames. Furthermore, the final thickness of the layer of deformable adhesive material between the seal carrier profile and the respective frames may be more precisely defined. In addition, the seal carrier profile may contribute to the positioning function of the locator blocks when it comes to the distance between the frames. In an embodiment, each first and second recess of the seal carrier profile is spaced from an inner face of the seal carrier profile and opens through an outer face of the seal carrier profile. Thereby, the above-mentioned features may be achieved.

In an embodiment, the frame sealing system includes an outer elastic gasket mutually sealing the first and second frames against each other thereby forming at least one outer drain channel between said adjacent frames. Thereby, the above-mentioned features may be achieved.

In an embodiment, the outer elastic gasket is mounted on an outer face of the seal car- rier profile. Thereby, the installation process of the curtain wall may be facilitated in that the outer elastic gasket may be mounted in the curtain wall together with the seal carrier profile.

In an embodiment, the outer elastic gasket has a first side and a second side separated by a wall of the gasket, the first side of the gasket is provided with a first outer sealing lip and a first inner sealing lip spaced from each other and both sealing against the first frame, thereby forming a first drain channel, and the second side of the gasket is provid- ed with a second outer sealing lip and a second inner sealing lip spaced from each other and both sealing against the second frame, thereby forming a second drain channel. Thereby, the above-mentioned features may be achieved. In an embodiment, the outer elastic gasket has an inner face facing the outer face of the seal carrier profile and an opposed outer face, and the outer face of the outer elastic gasket is covered by a joint of elastic sealant mutually sealing the first and second frames against each other. The joint of elastic sealant may create a further sealing barrier against water. Thereby, even better sealing properties may be achieved.

In an embodiment, the seal carrier profile is made of a first material having a first coefficient of thermal expansion and the locator blocks are made of a second material having a second coefficient of thermal expansion, and the second coefficient of thermal expansion is greater than or substantially greater than the first coefficient of thermal expan- sion. Thereby, the above-mentioned features may be achieved.

In a structurally particularly advantageous embodiment, perimeter seal carrier profiles extend along at least part of a perimeter of the curtain walling system and are provided with a membrane sealing against a wall or the like surrounding the curtain walling sys- tern, each perimeter seal carrier profile has a longitudinal direction, a frame contacting face abutting one or more frames and a membrane contacting face to which the membrane is adhered, the perimeter seal carrier profiles are fixed to the frames preferably by means of screws or nails, the frame contacting face of the perimeter seal carrier profile is provided with a recess in which a perimeter sealing strip is arranged, and in that the perimeter sealing strip is made of a deformable adhesive material adhering to the respective frame or frames. Thereby, a similar type of seal carrier profile that is used between adjacent frames may also be utilized for sealing and mounting of membrane along a perimeter of the curtain walling system. In an embodiment, an edge of the membrane is sandwiched between an edge of a metal cover profile and the membrane contacting face, and said edge of the metal cover profile is fixed to the perimeter seal carrier profiles preferably by means of screws or nails extending through the membrane. Thereby, sealed attachment of the membrane may be obtained when mounting the metal cover profile, because said edge of the metal cover profile may equal out the contact pressure obtained by means of the screws or nails over the entire edge of the membrane.

In an embodiment, a perimeter groove is formed between the metal cover profile and the one or more frames, and an elastic perimeter gasket is arranged in the perimeter groove and mutually seals the metal cover profile and the one or more frames against each other thereby forming at least one perimeter drain channel in the perimeter groove. The elastic perimeter gasket may provide a primary seal in front of the perimeter seal carrier profile, and any water leaking through said primary seal may be drained away by means of the at least one outer drain channel. Thereby, the risk of any water reaching the perimeter seal carrier profile itself may be substantially reduced. Because of the elastic perimeter gasket in front of the perimeter seal carrier profile, the pressure of any water that does reach the perimeter seal carrier profile will be substantially reduced. Because the sealing properties of the perimeter seal carrier profile provided with the deforma ble adhesive material may indeed by very good, the risk of any water entering through both the primary seal in the form of the perimeter gasket and the secondary seal in the form of the perimeter seal carrier profile may be very little.

In an embodiment, the elastic perimeter gasket has a first side and a second side separated by a wall of the gasket, the first side of the gasket is provided with a first outer sealing lip and a first inner sealing lip spaced from each other and both sealing against the one or more frames, thereby forming a first perimeter drain channel, and the sec- ond side of the gasket is provided with a second outer sealing lip and a second inner sealing lip spaced from each other and both sealing against the metal cover profile, thereby forming a second perimeter drain channel. Thereby, the features mentioned above in connection with the elastic gasket arranged between frames may also be obtained at the perimeter of the curtain wall.

In an embodiment, the elastic perimeter gasket has an inner face facing the metal cover profile and an opposed outer face, and the outer face of the elastic perimeter gasket is covered by a joint of elastic sealant mutually sealing the metal cover profile and the one or more frames against each other. Thereby, the features mentioned above in connection with the elastic gasket arranged between frames may also be obtained at the perimeter of the curtain wall.

In an embodiment, at corners of the wall or a part of a wall formed by the frames of the curtain walling system, the membrane contacting face of the perimeter seal carrier profiles meeting at the corner is provided with a recess in which an elastic corner piece is arranged at least substantially flush with the membrane contacting face, and pieces of membrane meeting at the corner are adhered to the elastic corner piece. Thereby, the pieces of membrane meeting at the corner may be sealed properly in relation to each other and in relation to the perimeter seal carrier profiles.

In an embodiment, a metal corner plate is arranged in the recess in the membrane con- tacting face and sandwiched between a bottom of the recess and the elastic corner piece. Thereby, the process of adhesion of the pieces of membrane meeting at the corner to the elastic corner piece may be facilitated in that the metal corner plate may provide a fixed support behind the elastic corner piece so that the pieces of membrane may be pressed onto the elastic corner piece during the adhesion process.

A third, separate invention relates to a curtain walling system including a number of frames arranged adjacently to each other and forming a wall or a part of a wall having an outside and an inside, the frames being arranged in at least two horizontally extending rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, wherein adjacent frames are sealed against each other by means of at least an outer sealing strip and an inner sealing strip being spaced in relation to each other thereby forming a drain channel between the outer and inner sealing strips, each drain channel being connected with a drain opening connecting said drain channel with the outside of the wall or of the part of a wall. The object of this third invention is to provide a curtain walling system having improved sealing properties.

In view of this object, adjacent frames are sealed against each other by means of a gas- ket having a first side and a second side separated by a wall of the gasket, the first side of the gasket is provided with a first outer sealing lip and a first inner sealing lip spaced from each other and both sealing against a first frame, thereby forming a first drain channel, and the second side of the gasket is provided with a second outer sealing lip and a second inner sealing lip spaced from each other and both sealing against a second frame, thereby forming a second drain channel.

Thereby, the gasket may create a double sealing effect in that both the outer sealing lips and the inner sealing lips seal against the respective frames. Furthermore, because the gasket forms a first drain channel and a second drain channel which are separated from each other by means of the wall of the gasket, an even better sealing effect may be obtained. In this way, any water possibly reaching one of the first or the second drain channels may immediately be drained away without reaching the opposed frame. Thereby, the risk that any water having reached one of the drain channels could leak into the building is further reduced.

In a structurally particularly advantageous embodiment, said gasket has the form an elastic gasket formed in one single piece, preferably having an H-shape.

In a structurally particularly advantageous embodiment, each horizontally extending gasket arranged between two horizontally extending rows of frames positioned on top of each other is formed by one or more gaskets arranged end to end, thereby forming a through going horizontal gasket extending from side to side of the curtain walling system, and, in each horizontally extending row of frames, a separate vertically extending gasket is arranged between each pair of adjacent frames and extends between a corre- sponding upper and lower through going horizontal gasket. Thereby, particularly good draining properties may be achieved. In an embodiment, each horizontally extending gasket arranged between two respective horizontally extending rows of frames positioned on top of each other is provided with a number of drain holes connecting a first and upper drain channel formed by said horizontally extending gasket with a second and lower drain channel formed by said hori- zontally extending gasket. Thereby, even better drainage of the curtain walling system may be ensured, because any water collected in a first and upper drain channel of a horizontally extending gasket may drain through said drain holes to a second and lower drain channel of said horizontally extending gasket and therefrom, the water may easily drain away into vertically extending drain channels. In the case of a through going hori- zontally extending gasket, said drain holes may ensure that any water not already drained away through drain openings above the through going horizontally extending gasket may continue to drain openings below the through going horizontally extending gasket. In an embodiment, each pair of first and second vertically extending drain channels formed by a common gasket is associated with at least one separate drain opening connecting said first and second vertically extending drain channels with the outside of the wall or of the part of a wall. Thereby it may be ensured that any water entering the system of drain channels at a particular horizontally extending row of frames is effectively drained away at that level of the curtain wall and does not continue any further downwards in the curtain wall.

In a structurally particularly advantageous embodiment, each pair of first and second vertically extending drain channels formed by a common gasket arranged in a first hori- zontally extending row of frames positioned on top of a second horizontally extending row of frames is associated with at least one separate drain opening arranged in the second horizontally extending row of frames.

In an embodiment, each pair of first and second vertically extending drain channels formed by a common gasket is associated with at least one separate vent opening connecting said first and second vertically extending drain channels with the outside of the wall or of the part of a wall. Thereby effective venting of the drain channels may be en- sured at each particular horizontally extending row of frames so that any water which has entered the drain channels may easily leave the channels again through the respective drain openings. In a structurally particularly advantageous embodiment, each pair of first and second vertically extending drain channels formed by a common gasket arranged in a certain horizontally extending row of frames is associated with at least one separate vent opening arranged in the same horizontally extending row of frames. In a structurally particularly advantageous embodiment, in each horizontally extending row of frames, at least one separate drain opening is arranged between each pair of adjacent frames at the position of the upper frame members of said pair of adjacent frames. In a structurally particularly advantageous embodiment, at least one separate vent opening is arranged below said drain opening, and the first and second vertically extending drain channels are blocked between the drain opening and the vent opening. Thereby it may better be ensured that water may be drained out at each level of frames so that water does not accumulate in downward direction.

In a structurally particularly advantageous embodiment, a common drain and vent insert forms a common drain opening for a pair of first and second vertically extending drain channels and a common vent opening for a pair of first and second vertically extending drain channels.

In a structurally particularly advantageous embodiment, the common drain and vent insert is arranged in line with a gasket forming the pair of first and second vertically extending drain channels vented by said drain and vent insert. The present invention furthermore relates to a method of mounting a curtain wall, whereby a number of frames are arranged adjacently to each other in at least two horizontally extending rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, and each frame being provided with a peripherally extending groove, wherein adjacent frames are sealed against each other by means of a frame sealing system in- eluding a seal carrier profile having a longitudinal direction, a first side being provided with a first sealing strip being brought to seal against a first frame and a second side being provided with a second sealing strip being brought to seal against a second frame, and the frame sealing system being brought to engage a peripherally extending groove of each frame.

The method is characterised by connecting each seal carrier profile to the respective first frame after the frame has been arranged in the curtain wall, whereby, firstly, at least two locator blocks are mounted on the first frame by bringing a first flange of a first side of each locator block into engagement with the peripherally extending groove of the first frame, whereby secondly, the seal carrier profile is arranged on the first frame so that it abuts the at least two locator blocks and so that the locator blocks are spaced in the longitudinal direction of the seal carrier profile, and whereby thirdly, the seal carrier profile is preferably fixed to the first frame, preferably by means of nails or screws, and whereby the respective second frame is subsequently arranged in the cur- tain wall, thereby bringing a second flange of a second side of each locator block into engagement with the peripherally extending groove of the second frame. Thereby, a particular simple and easy installation may be obtained. Furthermore, the above- mentioned features may be obtained. In an embodiment, when a first row of frames has been mounted, a through going horizontal seal carrier profile is arranged on top of the first row of frames so that the horizontal seal carrier profile extends from side to side of the curtain wall, and a second row of frames is arranged on top of the horizontal seal carrier profile. Thereby, tolerances of a horizontally extending row of frames may be eliminated by the arrangement of a through going horizontal seal carrier profile on top of said horizontally extending row of frames, thereby avoiding that such tolerances accumulate from bottom to top of the curtain wall. If the through going horizontal seal carrier profile is not level due to toler- ances, the positioning of the profile may be corrected by means of wedges or the like which are inserted below the profile before the next row of frames is installed on top of the profile. Furthermore, the above-mentioned features may be obtained. A fourth, separate invention relates to a frame sealing system adapted to mutually position and mutually seal a first frame and a second frame arranged adjacently to each other, each frame surrounding a window or door or other wall element and being provided with a peripherally extending groove, the frame sealing system including a seal carrier profile having a longitudinal direction, a first side being provided with a first seal- ing strip adapted to seal against the first frame and a second side being provided with a second sealing strip adapted to seal against the second frame, and the frame sealing system being adapted to engage the peripherally extending groove of each frame.

The object of this fourth invention is to provide a frame sealing system enabling optimi- zation of both isolation properties and positioning properties.

In view of this object, the frame sealing system includes at least two locator blocks adapted to be mounted on the seal carrier profile so that the locator blocks are spaced in the longitudinal direction of the seal carrier profile, and each locator block has a first side being provided with a first flange adapted to engage the peripherally extending groove of the first frame and a second side being provided with a second flange adapted to engage the peripherally extending groove of the second frame.

In this way, because the locator blocks are separate elements, which are connected to the seal carrier profile, the sealing and isolation properties of the continuous seal carrier profile may be optimized independently of the positioning properties of the locator blocks, and vice versa. The seal carrier profile can be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, because it does not need to carry the load of the forces acting between the frames. These forces may be taken up by the locator blocks which act to mutually position the frames. The locator blocks, in turn, may be produced as strong as necessary with only very little impact on the sealing properties. In an embodiment, the seal carrier profile is made of a first material having a first coefficient of thermal expansion and the locator block is made of a second material having a second coefficient of thermal expansion, and the second coefficient of thermal expan- sion is greater than or substantially greater than the first coefficient of thermal expansion. Because the seal carrier profile can be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, the seal carrier profile may preferably be made from a material having a relatively low coefficient of thermal expansion, such as aluminium, although the thermal conductivity may typi- cally be greater. As a result, the length of the seal carrier profiles will only change relatively little as a result of temperature changes and therefore, the change in length may easily be taken up for instance by means of an end gasket. Consequently, very good sealing properties may be achieved. Because the seal carrier profile does not extend all the way from the inside to the outside of the frames, even with a greater thermal conductivity of the seal carrier profile, it may be possible to avoid creating a thermal bridge. Because the locator blocks are separate, discretely arranged elements, which are connected to the seal carrier profile, the material of these may be chosen without taking into consideration the coefficient of thermal expansion, that is, a greater coefficient of thermal expansion may be accepted. Consequently, in order to not create a thermal bridge, a material having low thermal conductivity may be preferred, such as plastic.

In an embodiment, the first side of the seal carrier profile is provided with a first outer sealing strip and a first inner sealing strip spaced from each other and both adapted to seal against the first frame to form a first drain channel, and the second side of the seal carrier profile is provided with a second outer sealing strip and a second inner sealing strip spaced from each other and both adapted to seal against the second frame to form a second drain channel. Thereby, improved sealing properties may be achieved, because water or humidity possibly leaking through the outer sealing strips may be drained away through the drain channels. As a result, the risk of water or humidity leaking through the inner sealing strips may be substantially reduced. In a structurally particularly advantageous embodiment, each of said sealing strips is arranged in a corresponding groove of the seal carrier profile, said groove preferably being formed between a corresponding outermost flange and a corresponding inner- most flange of the seal carrier profile.

In an embodiment, in the unmounted position of the frame sealing system, each of said sealing strips protrudes from its corresponding groove by a distance corresponding to at least 1/2 of the depth of the groove and preferably corresponding to at least the depth of the groove. Thereby, the sealing strips may take up tolerances in the distance between adjacent frames and even better sealing properties may be ensured.

In an embodiment, the largest dimension of the seal carrier profile measured in the direction extending from the first to the second side of the seal carrier profile is smaller than the dimension between the first and the second side of the at least two locator blocks. Thereby it may be ensured that the seal carrier profile may not prevent proper relative positioning between adjacently arranged frames by means of the locator blocks. At the same time it may be ensured that when adjacently arranged frames are correctly relatively positioned by means of the locator blocks, there may still be sufficient room for the sealing strips to deform between the seal carrier profile and the corresponding frames without interfering with the relative positioning of the frames.

In an embodiment, the first side of each locator block is provided with at least one elastic gripper adapted to abut a first side wall of the peripherally extending groove of the first frame. Thereby, when the locator block is positioned on the first frame with its first flange engaging the peripherally extending groove of the first frame, the elastic gripper may ensure that the locator block and the seal carrier profile mounted on the locator block do not move when the second frame is positioned adjacent the first frame and the second flange of the locator block is brought to engage the peripherally extending groove of the second frame. In a structurally particularly advantageous embodiment, the at least one elastic gripper of each locator block is arranged between two spaced flanges forming the first flange of the locator block. In an embodiment, each locator block has first and second opposed ends each being provided with a first type of snap lock part adapted to engage a corresponding second type of snap lock part, and the seal carrier profile has first and second opposed longitudinal end sides each being provided with the second type of snap lock part. Thereby, the locator blocks may easily be connected with the seal carrier profile. Furthermore, if even better sealing properties are required, the first end of the locator blocks may be connected with a first seal carrier profile and the second end of the locator blocks may be connected with a second seal carrier profile. Furthermore, as an example, a variety of accessories such as a separate front gasket or a drip nose element may be attached to the second type of snap lock part of the seal carrier profile.

In a structurally particularly advantageous embodiment, the first type of snap lock part is formed by elastic grippers adapted to engage respective opposed side walls of a channel, and the second type of snap lock part is formed by a channel extending in the longitudinal direction of the seal carrier profile.

In an embodiment, the frame sealing system includes an outer sealing profile adapted to mutually seal the first and second frames against each other to form at least one outer additional drain channel between said adjacent frames. Thereby even better sealing properties may be achieved in that water or humidity possibly leaking through the outer sealing profile may be drained away through the at least one outer additional drain channel.

In a structurally particularly advantageous embodiment, the outer sealing profile has the form of an elastic sealing strip having a longitudinal flange adapted to engage a channel extending in the longitudinal direction of the seal carrier profile and having a first sealing lip adapted to seal against the first frame and a second sealing strip adapted to seal against the second frame to form a first outer additional drain channel and a second outer additional drain channel.

Preferably, the elastic sealing strip has a mounting channel extending in the longitudinal direction of the elastic sealing strip opposed to the longitudinal flange and between the first and second sealing lips. Thereby, a variety of accessories such as a separate front gasket or a drip nose element may by means of the mounting channel be attached to the elastic sealing strip. In an embodiment, a curtain walling system includes a number of frames arranged adjacently to each other and forming a wall or a part of a wall having an outside and an inside, the frames being arranged in at least two horizontally extending rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, wherein adjacent frames are sealed against each other by means of a frame sealing system as described above.

A fifth, separate invention relates to a curtain walling system including a number of frames arranged adjacently to each other and forming a wall or a part of a wall having an outside and an inside, the frames being arranged in at least two horizontally extending rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, wherein adjacent frames are sealed against each other by means of a frame sealing sys- tern including a seal carrier profile having a longitudinal direction, a first side being provided with a first sealing strip sealing against a first frame and a second side being provided with a second sealing strip sealing against a second frame, and the frame sealing system engaging a peripherally extending groove of each frame. The object of this fifth invention is to provide a curtain walling system being easy to install and having improved isolation properties. In view of this object, the frame sealing system includes a number of locator blocks spaced in the longitudinal direction of the seal carrier profile, and each locator block has a first side being provided with a first flange engaging the peripherally extending groove of the first frame and a second side being provided with a second flange engaging the peripherally extending groove of the second frame.

In this way, because the locator blocks are separate elements, the sealing and isolation properties of the continuous seal carrier profile may be optimized independently of the installation and positioning properties of the locator blocks, and vice versa. The seal carrier profile can be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames and does not create a thermal bridge, because it does not need to carry the load of the forces acting between the frames. These forces may be taken up by the locator blocks which act to mutually position the frames. The locator blocks, in turn, may be produced as strong as necessary with only very little impact on the sealing properties, because the locator blocks are separate elements that does not extend continuously along the seal carrier profile.

In an embodiment, each horizontally extending seal carrier profile arranged between two horizontally extending rows of frames positioned on top of each other is formed by one or more profiles arranged end to end, preferably via a gasket, thereby forming a through going horizontal seal carrier profile extending from side to side of the curtain walling system, and each vertically extending seal carrier profile arranged between two adjacent frames has a length corresponding at least approximately to the height of said adjacent frames and abuts, preferably via a gasket, any horizontally extending seal carri- er profile arranged just above and/or just below said vertically extending seal carrier profile. Thereby, tolerances of a horizontally extending row of frames may be eliminated by the arrangement of a through going horizontal seal carrier profile on top of said horizontally extending row of frames, thereby avoiding that such tolerances accumulate from bottom to top of the curtain wall. If the through going horizontal seal carrier pro- file is not level due to tolerances, the positioning of the profile may be corrected by means of wedges or the like which are inserted below the profile before the next row of frames is installed on top of the profile. In an embodiment, the locator blocks are mounted on the seal carrier profile, preferably by means of a snap lock system. This may facilitate the installation process in that the locator blocks may be mounted on the seal carrier profile, before mounting the seal carrier profile on a frame of the curtain wall, and thereby the seal carrier profile may be held in place on the frame by means of the locator blocks so that separate mounting means for the seal carrier profile may be dispensed with.

In an embodiment, the first side of the seal carrier profile is provided with a first outer sealing strip and a first inner sealing strip spaced from each other and both sealing against the first frame thereby forming a first drain channel, and the second side of the seal carrier profile is provided with a second outer sealing strip and a second inner sealing strip spaced from each other and both sealing against the second frame thereby forming a second drain channel. Thereby, improved sealing properties may be achieved, because water or humidity possibly leaking through the outer sealing strips may be drained away through the drain channels. As a result, the risk of water or humidity leaking through the inner sealing strips may be su bstantially reduced.

In an embodiment, the frame sealing system includes an outer sealing profile mutually sealing the first and second frames against each other thereby forming at least one outer additional drain channel between said adjacent frames. Thereby even better sealing properties may be achieved in that water or humidity possibly leaking in through the outer sealing profile may be drained away through the at least one outer additional drain channel.

In a structurally particularly advantageous embodiment, the outer sealing profile has the form of an elastic sealing strip having a longitudinal flange engaging a channel extending in the longitudinal direction of the seal carrier profile and having a first sealing lip sealing against the first frame and a second sealing lip sealing against the second frame thereby forming a first outer additional drain channel and a second outer additional drain channel. Preferably, the elastic sealing strip has a mounting channel extending in the longitudinal direction of the elastic sealing strip opposed to the longitudinal flange and between the first and second sealing lips. Thereby, a variety of accessories such as a separate front gasket or a drip nose element may by means of the mounting channel be attached to the elastic sealing strip.

In a structurally particularly advantageous embodiment, seal carrier profiles extending between two horizontally extending rows of frames are provided with a drip nose element, and the drip nose element is mounted by means of mounting screws inserted into a channel extending in the longitudinal direction of the seal carrier profile or inserted into the mounting channel of an elastic sealing strip mounted on the seal carrier profile. Thereby, water may be led away from the curtain wall at the level of each row of frames, thereby avoiding possible leakages further downwards the curtain wall. Installation may be facilitated in that mounting screws may simply be inserted into a channel of the seal carrier profile or of an elastic sealing strip.

In a structurally particularly advantageous embodiment, seal carrier profiles extending along a perimeter of the curtain walling system are provided with stacker flashing or membrane sealing against a wall or the like surrounding the curtain walling system, and the stacker flashing or membrane is mounted by means of mounting screws inserted into a channel extending in the longitudinal direction of the seal carrier profile or inserted into the mounting channel of an elastic sealing strip mounted on the seal carrier profile. Thereby, the same type of seal carrier profile that is used between adjacent frames may also be utilized for sealing and mounting of stacker flashing or membrane along a perimeter of the curtain walling system.

In a structurally particularly advantageous embodiment, seal carrier profiles extending along a perimeter of the curtain walling system are provided with stacker flashing or membrane sealing against a wall or the like surrounding the curtain walling system, and the stacker flashing or membrane is provided with an edge inserted into a groove of the seal carrier profiles. Thereby, the same type of seal carrier profile that is used between adjacent frames may also be utilized for sealing and mounting of stacker flashing or membrane along a perimeter of the curtain walling system. The groove of the seal carrier profiles in which the edge of the stacker flashing or membrane is inserted may be a groove which is used for mounting a sealing when the same type of seal carrier profile is mounted between adjacent frames. According to this embodiment, the mounting of the stacker flashing or membrane may be even further facilitated.

In a structurally particularly advantageous embodiment, seal carrier profiles extending along a perimeter of the curtain walling system are mounted on the frames of the curtain walling system by means of perimeter brackets being positioned on said frames by means of flap extensions fitted in the peripherally extending groove of the respective frames and mounted on said frames by means of screws, and the perimeter brackets are mounted on the seal carrier profiles by means of screws inserted into a channel extending in the longitudinal direction of the seal carrier profiles. Thereby, along the perimeter of the curtain walling system, the locator blocks may be dispensed with, and installation of the curtain walling system may be facilitated.

A sixth, separate invention relates to a curtain walling system including a number of frames arranged adjacently to each other and forming a wall or a part of a wall having an outside and an inside, the frames being arranged in at least two horizontally extend- ing rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, wherein adjacent frames are sealed against each other by means of at least an outer sealing strip and an inner sealing strip being spaced in relation to each other thereby forming a drain channel between the outer and inner sealing strips.

The object of this sixth invention is to provide a curtain walling system having improved sealing properties. In view of this object, in each horizontally extending row of frames, each drain channel extending vertically between two adjacent frames is provided with a drain opening con- necting said vertically extending drain channel with the outside of the wall or of the part of a wall.

In this way, by draining each drain channel at each level of frames, it may be ensured that the drain channels are always sufficiently drained so that they are not overloaded even in heavy rain, thereby minimizing a possible water pressure on the inner sealing strip. Therefore, even if water should pass the outer sealing strip, water is very unlikely to also pass the inner sealing strip. In an embodiment, each said vertically extending drain channel is blocked just below each said drain opening. Thereby it may better be ensured that water may be drained out at each level of frames so that water does not accumulate in downward direction.

In a structurally particularly advantageous embodiment, each said drain opening is ar- ranged at the position of the lower frame members of said two adjacent frames. Thereby, it may in particular be advantageous that water may be drained directly from a drain channel extending horizontally between two adjacent rows of frames so that water does not accumulate in the drain channels. In an embodiment, preferably at the position of the upper frame members, each drain channel extending vertically between two adjacent frames is provided with a vent opening connecting said vertically extending drain channel with the outside of the wall or a part of a wall. Thereby it may be avoided that under pressure builds up in the drain channels and prevents proper draining of the drain channels, and it may consequently even better be ensured that water is drained from the drain channels at each level of frames.

In a structurally particularly advantageous embodiment, adjacent frames are sealed against each other by means of a frame sealing system including a seal carrier profile having a longitudinal direction, a first side being provided with a first outer sealing strip and a first inner sealing strip spaced from each other and both sealing against a first frame of said adjacent frames thereby forming a first drain channel, and a second side being provided with a second outer sealing strip and a second inner sealing strip spaced from each other and both sealing against a second frame of said adjacent frames thereby forming a second drain channel. Thereby, a more precise arrangement of the sealing strips may be achieved, resulting in a better sealing effect. Furthermore, an even better sealing effect may be obtained, because a vertical drain channel arranged between two adjacent frames is split up into two separate drain channels. Thereby, if, for instance, water enters the first outer sealing strip, the water will be drained away in the first drain channel separately from the second drain channel. Therefore, there is no risk of this water entering the second inner sealing strip. Therefore, the risk of this water leaking to the inside of the curtain wall is half the risk that would exist in the case of only one vertical drain channel.

In an embodiment, each horizontally extending seal carrier profile arranged between two horizontally extending rows of frames positioned on top of each other is formed by one or more profiles arranged end to end, preferably via a gasket, thereby forming a through going horizontal seal carrier profile extending from side to side of the curtain walling system, and each vertically extending seal carrier profile arranged between two adjacent frames has a length corresponding at least approximately to the height of said adjacent frames and abuts, preferably via a gasket, any horizontally extending seal carri- er profile arranged just above and/or just below said vertically extending seal carrier profile. Thereby, tolerances of a horizontally extending row of frames may be eliminated by the arrangement of a through going horizontal seal carrier profile on top of said horizontally extending row of frames, thereby avoiding that such tolerances accumulate from bottom to top of the curtain wall. If the through going horizontal seal carrier pro- file is not level due to tolerances, the positioning of the profile may be corrected by means of wedges or the like which are inserted below the profile before the next row of frames is installed on top of the profile. Furthermore, the through going horizontal seal carrier profile may ensure improved drainage of the curtain walling system, because any water collected in horizontal drain channels of the through going horizontal seal carrier profile may easily drain away into vertically extending drain channels as the water is not hindered by means of gaskets or sealings which could otherwise be that case at connection points between horizontal seal carrier profiles and vertical seal carrier profiles. In an embodiment, each horizontally extending seal carrier profile arranged between two respective horizontally extending rows of frames positioned on top of each other is provided with a number of drain holes connecting a first and upper drain channel of said horizontally extending seal carrier profile with a second and lower drain channel of said horizontally extending seal carrier profile. Thereby, even better drainage of the curtain walling system may be ensured, because any water collected in a first and upper drain channel of a horizontal seal carrier profile may drain through said drain holes to a second and lower drain channel of said horizontally extending seal carrier profile and there- from, the water may easily drain away into vertically extending drain channels. In the case of a through going horizontal seal carrier profile, said drain holes may ensure that any water not already drained away through drain openings above the through going horizontal seal carrier profile may continue to drain openings below the through going horizontal seal carrier profile.

In a structurally particularly advantageous embodiment, said drain openings connecting said vertically extending drain channels with the outside of the wall or of the part of a wall are formed in that the respective outer sealing strip is cut away locally, and in that the respective inner sealing strip is bent so that is crosses the respective vertically ex- tending drain channel and thereby blocks said vertically extending drain channel in downward direction just below the respective drain opening. Thereby it may better be ensured that water may be drained out at each level of frames so that water does not accumulate in downward direction. Bending the inner sealing strip so that is crosses the respective vertically extending drain channel may be a simple and easy way to create a suitable oblique drain surface blocking the drain channel and guiding water to the drain opening.

In a structurally particularly advantageous embodiment, each of said outer and inner sealing strips is arranged between a corresponding outermost flange and a correspond- ing innermost flange of the seal carrier profile. In a structurally particularly advantageous embodiment, at said drain openings, the outermost and innermost flanges holding the outer sealing strips are cut away locally, and, at said drain openings, the outermost flanges holding the inner sealing strips are cut away locally.

In a structurally particularly advantageous embodiment, vent openings connecting said vertically extending drain channel with the outside of the wall or a part of a wall are formed in that the respective outer sealing strip is cut away locally, preferably with a downwardly sloping cut in outward direction. Said downwardly sloping cut may guide any water in outward direction away from the drain channel and the vent openings may therefore possibly act as supplementary drain openings.

In an embodiment, at said vent openings, the outermost and innermost flanges holding the outer sealing strips are cut away locally.

In an embodiment, the frame sealing system includes a number of locator blocks, preferably mounted on the seal carrier profile, and mounted so that the locator blocks are spaced in the longitudinal direction of the seal carrier profile, and each locator block has a first side being provided with a first flange engaging a peripherally extending groove of a first frame and a second side being provided with a second flange engaging a peripherally extending groove of a second frame. Thereby, the above-mentioned features may be obtained.

In an embodiment, the seal carrier profile is made of a first material having a first coeffi- cient of thermal expansion and the locator block is made of a second material having a second coefficient of thermal expansion, and the second coefficient of thermal expansion is greater than or substantially greater than the first coefficient of thermal expansion. Thereby, the above-mentioned features may be obtained. In an embodiment, each locator block has first and second opposed ends each being provided with a first type of snap lock part engaging a corresponding second type of snap lock part of the seal carrier profile, and the seal carrier profile has first and second opposed longitudinal end sides each being provided with the second type of snap lock part. Thereby, the above-mentioned features may be obtained.

In a structurally particularly advantageous embodiment, the first type of snap lock part is formed by elastic grippers engaging respective opposed side walls of a channel, and the second type of snap lock part is formed by a channel extending in the longitudinal direction of the seal carrier profile.

In an embodiment, the frame sealing system includes an outer sealing profile sealing adjacent frames against each other thereby forming at least one outer additional drain channel between said adjacent frames. Thereby, the above-mentioned features may be obtained.

In a structurally particularly advantageous embodiment, the outer sealing profile has the form of an elastic sealing strip having a longitudinal flange engaging a channel extending in the longitudinal direction of the seal carrier profile and having a first sealing lip sealing against a first frame and a second sealing strip sealing against a second frame, thereby forming a first outer additional drain channel and a second outer additional drain channel. Preferably the elastic sealing strip has a mounting channel extending in the longitu- dinal direction of the elastic sealing strip opposed to the longitudinal flange and between the first and second sealing lips. Thereby, the above-mentioned features may be obtained.

In a structurally particularly advantageous embodiment, respective first and second drain openings of respective first and second vertically extending drain channels formed on the first and second side, respectively, of a vertically extending seal carrier profile, are provided with a common drain cap mounted on said vertically extending seal carrier profile. In a structurally particularly advantageous embodiment, at said drain openings, the outer sealing profile is cut away locally, and the common drain cap is mounted on the outer sealing profile just above the opening formed by cutting away part of the outer sealing profile, and the drain cap preferably has a flange arranged in a mounting channel extending in the longitudinal direction of the elastic sealing strip.

In a structurally particularly advantageous embodiment, respective first and second vent openings of respective first and second vertically extending drain channels formed on the first and second side, respectively, of a vertically extending seal carrier profile, are provided with a common vent cap mounted on said vertically extending seal carrier profile. In a structurally particularly advantageous embodiment, at said vent openings, the outer sealing profile is cut away locally, and the common vent cap is mounted on the outer sealing profile just above the opening formed by cutting away part of the outer sealing profile, and the vent cap preferably has a flange arranged in a mounting channel extending in the longitudinal direction of the elastic sealing strip.

A seventh, separate invention relates to a method of mounting a curtain wall, whereby a number of frames are arranged adjacently to each other in at least two horizontally extending rows of frames positioned on top of each other, each frame including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window or door or other wall element, and each frame being provided with a peripherally extending groove, wherein adjacent frames are sealed against each other by means of a frame sealing system including a seal carrier profile having a longitudinal direction, a first side being provided with a first sealing strip being brought to seal against a first frame and a second side being provided with a second sealing strip being brought to seal against a second frame, and the frame sealing system being brought to engage a peripherally extending groove of each frame.

This method is characterised by connecting each seal carrier profile to the respective first frame after the frame has been arranged in the curtain wall, whereby the seal carri- er profile is mounted on the first frame by means of a least to locator blocks connected to the seal carrier profile and spaced in the longitudinal direction of the seal carrier profile by bringing a first flange of a first side of each locator block into engagement with the peripherally extending groove of the first frame, and whereby the respective second frame is subsequently arranged in the curtain wall, thereby bringing a second flange of a second side of each locator block into engagement with the peripherally extending groove of the second frame. Thereby, a particular simple and easy installation may be obtained. Furthermore, the above-mentioned features may be obtained.

In an embodiment, when a first row of frames has been mounted, a through going horizontal seal carrier profile is arranged on top of the first row of frames so that the horizontal seal carrier profile extends from side to side of the curtain wall, and a second row of frames is arranged on top of the horizontal seal carrier profile. Thereby, tolerances of a horizontally extending row of frames may be eliminated by the arrangement of a through going horizontal seal carrier profile on top of said horizontally extending row of frames, thereby avoiding that such tolerances accumulate from bottom to top of the curtain wall. If the through going horizontal seal carrier profile is not level due to toler- ances, the positioning of the profile may be corrected by means of wedges or the like which are inserted below the profile before the next row of frames is installed on top of the profile. Furthermore, the above-mentioned features may be obtained.

Fig. 90 illustrates a longitudinal cross-section through the drain cap of Fig. 89. Fig. 7 and 8 illustrate a frame sealing system 1 according to a described invention, adapted to mutually position and mutually seal a first frame 2 and a second frame 3 arranged adjacently to each other. Each frame surrounds a window 4 or door or other wall element and is provided with a peripherally extending groove 5 as it is common in wooden window frames. However, although the frame sealing system 1 according to this invention may be particularly suitable for wooden frames, it is equally applicable to any other type of frame being provided with a peripherally extending groove, such as frames composed by plastic or aluminium profiles. The frame sealing system 1 includes a seal carrier profile 6 having a longitudinal direction L, as indicated in Fig. 4. Referring to Fig. 3, the seal carrier profile 6 has a first side 7 being provided with a first outer sealing strip 8 and a first inner sealing strip 9 spaced from each other and both adapted to seal against the first frame 2 to form a first drain channel 18. Likewise, the seal carrier profile 6 has a second side 10 provided with a second outer sealing strip 11 and a second inner sealing strip 12 spaced from each other and both adapted to seal against the second frame 3 to form a second drain channel 19. Furthermore, the frame sealing system 1 according to a described invention includes at least two locator blocks 13 adapted to be mounted on the seal carrier profile 6 so that the locator blocks 13 are spaced in the longitudinal direction L of the seal carrier profile 6. Comparing Figs. 10 and 11, illustrating comparable embodiments including a horizontally extending seal carrier profile 6, it may be understood that at some positions along the length of the seal carrier profile 6, locator blocks 13 are arranged as seen in Fig. 10, and at other positions along the seal carrier profile 6, frame packers 66 are arranged as seen in Fig. 11. At the positions of the frame packers 66, the adjacent frames 2, 3 may be fixed together by means of frame screws 67. Fig. 12 illustrates a view from the left of Fig. 11; however, the locator blocks 13 are not illustrated in Fig. 12.

Referring to Figs. 5 and 6, each locator block 13 has a first side 14 being provided with a first flange 15 adapted to engage the peripherally extending groove 5 of the first frame 2 and a second side 16 being provided with a second flange 17 adapted to engage the peripherally extending groove 5 of the second frame 3. Thereby, the forces acting be- tween the frames may be taken up by the locator blocks which act to mutually position the frames. Being separate elements, the locator blocks may be produced as strong as necessary with only very little impact on the sealing properties.

The sealing and isolation properties of the continuous seal carrier profile 6 may be opti- mized independently of the positioning properties of the locator blocks 13, and vice versa. The seal carrier profile can be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, because it does not need to carry the load of the forces acting between the frames.

Preferably, the seal carrier profile 6 is made of a first material having a first coefficient of thermal expansion and the locator block 13 is made of a second material having a second coefficient of thermal expansion, wherein the second coefficient of thermal expansion is greater than or substantially greater than the first coefficient of thermal expansion. In a preferred embodiment, the seal carrier profile 6 is made of aluminium, and the locator blocks 13 are made of a plastic material. Although the thermal conductivity of aluminium is relatively high, the seal carrier profile can be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, and even with a greater thermal conductivity of the seal carrier profile, it may therefore be possible to avoid creating a thermal bridge.

By making the seal carrier profiles 6 of aluminium, the length of the seal carrier profiles will only change relatively little as a result of temperature changes and therefore, the change in length may easily be taken up for instance by means of an end gasket. Conse- quently, very good sealing properties may be achieved. However, the seal carrier profiles 6 may be made of any suitable material, preferably having thermal expansion properties similar to or better than those of aluminium.

The locator blocks 13 are separate, discretely arranged elements, which are relatively short compared to the length of the seal carrier profiles. Therefore, the material of the locator blocks may be chosen without taking into consideration the coefficient of thermal expansion, that is, a greater coefficient of thermal expansion may be accepted. Consequently, in order to not create a thermal bridge, a material having low thermal conductivity may be preferred, such as plastic.

As seen in Fig. 3, each of said sealing strips 8, 9, 11, 12 is arranged in a corresponding groove 20 of the seal carrier profile 6, wherein said groove 20 is formed between a cor- responding outermost flange 21 and a corresponding innermost flange 22 of the seal carrier profile 6. The seal carrier profile 6 may have different cross-sections, and another example is illustrated in Fig. 25. As also seen in Fig. 3, in the unmounted position of the frame sealing system 1, each of said sealing strips 8, 9, 11, 12 protrudes from its corresponding groove 20 by a distance corresponding to at least 1/2 of the depth of the groove, and preferably corresponding to at least the depth of the groove. In this way, the sealing strips may take up relatively large tolerances in the distance between adjacent frames, and thereby even better seal- ing properties may be ensured. As illustrated, preferably the sealing strips 8, 9, 11, 12 are hollow and they are preferably made of an elastic material, such as rubber, for instance EPDM, or the like. Furthermore, the sealing strips 8, 9, 11, 12 may have different cross-sections, and other examples are illustrated in Figs. 28 and 29. In order to ensure that the seal carrier profile does not prevent proper relative positioning between adjacently arranged frames by means of the locator blocks, the largest dimension d of the seal carrier profile 6 measured in the direction extending from the first side 7 to the second side 10 of the seal carrier profile 6 is smaller than the dimension D between the first side 14 and the second side 16 of the at least two locator blocks 13. The dimensions d and D, respectively, are indicated in Figs. 3 and 5. This also means that when adjacently arranged frames are correctly relatively positioned by means of the locator blocks 13, there may still be sufficient room for the sealing strips 8, 9, 11, 12 to deform between the seal carrier profile 6 and the corresponding frames 2, 3 without interfering with the relative positioning of the frames. When deforming, the sealing strips 8, 9, 11, 12 may be squeezed between the outer end of the outermost and innermost flanges 21, 22 of the seal carrier profile 6 and the frames 2, 3.

As illustrated in Figs. 5 and 6, the first side 14 of each locator block 13 is provided with two elastic grippers 23 arranged side by side and adapted to abut a first side wall of the peripherally extending groove 5 of the first frame 2. Thereby, when the locator block is positioned on the first frame 2 with its first flange 15 engaging the peripherally extending groove 5 of the first frame 2, the elastic grippers 23 may ensure that the locator block 13 and the seal carrier profile 6 mounted on the locator block do not move when the second frame 3 is positioned adjacent the first frame 2 and the second flange 17 of the locator block 13 is brought to engage the peripherally extending groove 5 of the second frame 3. The elastic grippers 23 are arranged between two spaced flanges form- ing the first flange 15 of the locator block 13, however, the elastic grippers 23 may have different configurations, and they may also be arranged directly on the first flange 15 in any suitable way. Instead of elastic grippers 23, the first flange 15 may simply be formed a little thicker than the second flange 17, so that the first flange 15 fits into the groove 5 with a narrow fit.

As furthermore illustrated in Figs. 5 and 6, each locator block 13 has first and second opposed ends 24, 25 each being provided with a first type of snap lock part 26 adapted to engage a corresponding second type of snap lock part 27. The first type of snap lock part 26 is formed by elastic grippers 30 adapted to engage respective opposed side walls 31 of a channel 32 of the second type of snap lock part 27. However, any suitable type of snap lock system may be applied.

As illustrated in Fig. 3, the seal carrier profile 6 has first and second opposed longitudinal end sides 28, 29 each being provided with the second type of snap lock part 27. The second type of snap lock part 27 is formed by a channel 32 extending in the longitudinal direction L of the seal carrier profile 6.

By means of the snap lock system, the locator blocks 13 may easily be connected with the seal carrier profile 6. Furthermore, if even better sealing properties are required, the first end 24 of the locator blocks 13 may be connected with a first seal carrier profile 6 and the second end 25 of the locator blocks 13 may be connected with a second seal carrier profile 6. Furthermore, as an example, a variety of accessories such as a separate front gasket 79 or a drip nose element 43 may be attached to the second type of snap lock part 27 of the seal carrier profile 6.

As illustrated in Figs. 3 and 8, the frame sealing system 1 includes an outer sealing profile 33 adapted to mutually seal the first and second frames 2, 3 against each other to form two outer additional drain channels 34, 35 between the adjacent frames 2, 3. Thereby even better sealing properties may be achieved in that water or humidity possibly leaking through the outer sealing profile 33 may be drained away through the outer additional drain channels. The outer sealing profile 33 has the form of an elastic seal- ing strip having a longitudinal flange 36 adapted to engage the channel 32 extending in the longitudinal direction L of the seal carrier profile 6 and having a first sealing lip 37 adapted to seal against the first frame 2 and a second sealing lip 38 adapted to seal against the second frame 3 whereby the first outer additional drain channel 34 and the second outer additional drain channel 35 are formed. The elastic sealing strip has a mounting channel 39 extending in the longitudinal direction of the outer sealing profile 33 opposed to the longitudinal flange 36 and between the first and second sealing lips 37, 38. The outer sealing profile 33 may have different cross-sections, and other examples are illustrated in Figs. 26 and 27. Figs. 1 and 2 illustrate in a purely schematic way a curtain walling system 40 incorporating a frame sealing system 1 as described above. The curtain walling system 40 includes a number of frames 2, 3 arranged adjacently to each other and forming a wall or a part of a wall having an outside 41 and an inside 42 as illustrated in Figs. 7 and 8. For the sake of simplicity, the frames 2, 3 are not shown in Figs. 1 and 2, but only the intermediately arranged horizontal and vertical seal carrier profiles 6 are indicated. In the embodiment illustrated in Fig. 1, the frames are arranged in three horizontally extending rows of frames, wherein each row is formed by four frames. In the embodiment illustrated in Fig. 2, the frames are arranged in two horizontally extending rows of frames, wherein each row is formed by three frames. The rows of frames are positioned on top of each other, and each frame includes an upper frame member, a lower frame member, a first side frame member and a second side frame member, wherein each frame 2, 3 surrounds a window 4 or door or other wall element. The adjacent frames in each row are sealed against each other by means of a vertically arranged seal carrier profile 6 as described above, and the rows of frames are sealed against each other by means of a hori- zontally arranged seal carrier profile 6 as described a bove. Each horizontally extending seal carrier profile 6 arranged between two horizontally extending rows of frames positioned on top of each other is formed by one or more profiles arranged end to end, thereby forming a through going horizontal seal carrier profile 6 extending from side to side of the curtain walling system 40. Preferably the profiles are arranged end to end via a gasket 56 and preferably the profiles are mutually positioned via a connecting piece 88 adapted to be inserted into the ends of the profiles. A suitable connecting piece 88 with gasket 56 is illustrated in Fig. 40. The connecting piece 88 has downwardly protruding taps adapted to be inserted and lock into holes in the profiles.

Each vertically extending seal carrier profile 6 arranged between two adjacent frames 2, 3 has a length corresponding at least approximately to the height of said adjacent frames and a buts any horizontally extending seal carrier profile 6 arranged just above and/or just below said vertically extending seal carrier profile 6. The vertically extending seal carrier profiles 6 abut the horizontally extending seal carrier profiles 6 via upper and lower gaskets 57, 58, respectively, as illustrated in Figs. 36 and 37.

As illustrated in Figs. 10, 11 and 13, horizontally extending seal carrier profiles 6 extending between two horizontally extending rows of frames 2, 3 are provided with a drip nose element 43. In the embodiments illustrated in these figures, the drip nose element 43 is mounted by means of mounting screws 44 inserted into the mounting channel 39 of the elastic sealing strip 33 mounted on the seal carrier profile 6. However, in other embodiments, these mounting screws 44 may be inserted directly into the channel 32 extending in the longitudinal direction L of the seal carrier profile 6.

In the embodiments illustrated in Figs. 14 and 16, seal carrier profiles 6 extending along a perimeter 45 of the curtain walling system 40 are provided with stacker flashing or membrane 46 sealing against a wall 47 or the like surrounding the curtain walling system. The stacker flashing or membrane 46 is mounted by means of mounting screws 44 inserted into the mounting channel 39 of an elastic sealing strip 39 mounted on the seal carrier profile 6. In the embodiment illustrated in Fig. 14, the seal carrier profiles 6 extend horizontally along the upper part of the perimeter 45 of the curtain walling system 40. In the embodiment illustrated in Fig. 16, the seal carrier profiles 6 extend vertically along a side part of the perimeter 45 of the curtain walling system 40.

In the embodiment illustrated in Fig. 17, seal carrier profiles 6 extending vertically along a frame of the curtain walling system 40 at a supporting column 74 of the curtain walling system are provided with stacker flashing or membrane 46 at the outside 41 in the same way as described just above regarding the perimeter 45.

A suitable mounting screw 44 for the mounting of a drip nose element 43, stacker flash- ing or membrane 46 or the like is illustrated in Figs. 41 to 44. The support disc 84 of the mounting screw 44 ensures that for instance a drip nose element 43 may be fixed adequately between the support disc 84 and a nut 83 for the mounting screw, also when mounting directly on an outer sealing profile 33 of elastic material. Otherwise, the drip nose element 43 would abut the outer sealing profile 33 and would be a ble to move as a result of wind.

Furthermore, in the embodiments illustrated in Figs. 14 and 16, seal carrier profiles 6 extending along a perimeter 45 of the curtain walling system 40 are provided with stacker flashing or membrane 46 sealing against a wall 47 or the like surrounding the curtain walling system, wherein the stacker flashing or membrane 46 is provided with an edge 73 inserted into a groove of the seal carrier profiles 6. Thereby, the same type of seal carrier profile 6 that is used between adjacent frames 2, 3 may also be utilized for sealing and mounting of stacker flashing or membrane 46 along a perimeter of the curtain walling system 40. The groove 20 of the seal carrier profiles 6 in which the edge 73 of the stacker flashing or membrane is inserted may be a groove 20 which is used for mounting a sealing 8, 9, 11, 12 when the same type of seal carrier profile 6 is mounted between adjacent frames.

In the embodiment illustrated in Fig. 17, seal carrier profiles 6 extending along a frame of the curtain walling system 40 at a supporting column 74 of the curtain walling system are provided with stacker flashing or membrane 46 sealing against supporting column 74, wherein the stacker flashing or membrane 46 is provided with an edge 73 inserted into a groove 20 of the seal carrier profiles 6 in the same way as described just above regarding the perimeter 45.

In the embodiments illustrated in Figs. 14, 16, seal carrier profiles 6 extending along the perimeter 45 of the curtain walling system 40 are mounted on the frames 2, 3 of the curtain walling system by means of perimeter brackets 48 as shown in Fig. 24. The perimeter brackets 48 are positioned on said frames by means of flap extensions 49 fitted in the peripherally extending groove 5 of the respective frames 2, 3 and are mounted on said frames by means of screws 50. The perimeter brackets 48 are mounted on the seal carrier profiles 6 by means of screws 51 inserted into the channel 32 extending in the longitudinal direction L of the seal carrier profiles 6. Thereby, along the perimeter of the curtain walling system, the locator blocks 13 may be dispensed with, and installation of the curtain walling system may be facilitated. The perimeter brackets 48 may ensure a good permanent fixture of the seal carrier profiles 6 along the perimeter.

As illustrated in Fig. 15, a specific starter profile 69 of the curtain walling system 40 may be used below the bottom row of frames of the curtain wall. The horizontally extending starter profile 69 is illustrated in cross-section in Fig. 18. The starter profile 69 ensures a fixed and levelled starting point for the curtain wall. The starter profile 69 supports a horizontal seal carrier profiles 6 sealing against the lower perimeter of the curtain wall. Furthermore, the starter profile 69 is provided with a number of support blocks 72 replacing the locator blocks at this level of the curtain wall. Each support block 72 correspond to the first or second flange 15, 17 of the locator blocks 13 and fits into the peripheral groove 5 of the frames 2, 3. As indicated in Fig. 15 by means of arrows, the starter profile 69 may be adjusted in vertical and horizontal direction thereby ensuring proper levelling. The starter profile 69 is composed by a first part 70 and a second part 71 and it also carries a stacker flashing or membrane 46 forming a drip nose. As seen in Figs. 19 and 20, the ends of the starter profile 69 may be provided with an end bracket 75 adjustable in the length direction of the starter profile in order to fit vertically ex- tending seal carrier profiles 6 abutting the starter profile at its ends. The end bracket 75 is provided with a gasket 76 made of elastic foam material and having a vertical groove 77 for insertion of an edge of a stacker flashing or membrane 46. Fig. 2 illustrates in a purely schematic way how the curtain walling system 40 is provided with a draining system. Adjacent frames 2, 3 are sealed against each other by means of a frame sealing system 1 as described above. In each horizontally extending row of frames 2, 3, each drain channel 18, 19, 34, 35 extending vertically between two adjacent frames 2, 3 is provided with a drain opening 52 connecting said vertically extending drain channel with the outside 41 of the wall. Each said drain opening 52 is arranged at the position 53 of the lower frame members of said two adjacent frames 2, 3. Furthermore, at the position 54 of the upper frame members, each drain channel 18, 19, 34, 35 extend- ing vertically between two adjacent frames 2, 3 is provided with a vent opening 55 connecting said vertically extending drain channel with the outside 41 of the wall. By draining each drain channel at each level of frames, it may be ensured that the drain channels are always sufficiently drained so that they are not overloaded even in heavy rain, thereby minimizing a possible water pressure on the inner sealing strip. Therefore, even if water should pass the outer sealing strip, water is very unlikely to also pass the inner sealing strip. The vent openings serve to avoid that under pressure builds up in the drain channels and thereby prevents proper draining of the drain channels, and it may consequently even better be ensured that water is drained from the drain channels at each level of frames.

As illustrated in Figs. 38 and 39, each horizontally extending seal carrier profile 6 arranged between two respective horizontally extending rows of frames 2, 3 positioned on top of each other is provided with a number of drain holes 59 connecting a first and upper drain channel 60 of said horizontally extending seal carrier profile 6 with a second and lower drain channel 61 of said horizontally extending seal carrier profile. Thereby, any water collected in a first and upper drain channel of a horizontal seal carrier profile may drain through said drain holes to a second and lower drain channel of said horizontally extending seal carrier profile and therefrom, the water may easily drain away into vertically extending drain channels. In the case of a through going horizontal seal carrier profile, said drain holes 59 may ensure that any water not already drained away through drain openings above the through going horizontal seal carrier profile may continue to drain openings below the through going horizontal seal carrier profile 6. As illustrated in Figs. 31 to 37, each said vertically extending drain channel 18, 19, 34, 35 is blocked just below each said drain opening 52. The drain openings 52 connecting said vertically extending drain channels 18, 19, 34, 35 with the outside 41 of the wall are formed in that the respective outer sealing strip 33 is cut away locally, and in that the respective inner sealing strip 9, 12 is bent so that is crosses the respective vertically extending drain channel 18, 19 and thereby blocks said vertically extending drain channel in downward direction just below the respective drain opening 52. The part of the inner sealing strip 9, 12 that is bent may be glued to the seal carrier profile 6, and therefore, it may be advantageous that the sealing strip 9, 12 is provided with ribs at its bottom as seen in Figs. 28 and 29.

At said drain openings 52, the outermost and innermost flanges 21, 22 holding the outer sealing strips 8, 11 are cut away locally, and, at said drain openings 52, the outermost flanges 21 holding the inner sealing strips 9, 12 are cut away locally.

Vent openings 55 connecting said vertically extending drain channel 18, 19 with the outside 41 of the wall or a part of a wall are formed in that the respective outer sealing strip 33 is cut away locally, preferably with a downwardly sloping cut in outward direction. At said vent openings 55, the outermost and innermost flanges 21, 22 holding the outer sealing strips 8, 11 are cut away locally.

As seen in Figs. 36 and 38, respective first and second drain openings 52 of respective first and second vertically extending drain channels 18, 19, 34, 35 formed on the first and second side 7, 10, respectively, of a vertically extending seal carrier profile 6, are provided with a common drain cap 62 mounted on said vertically extending seal carrier profile 6. At said drain openings 52, the outer sealing profile 33 is cut away locally, and the common drain cap 62 is mounted on the outer sealing profile 33 just above the opening formed by cutting away part of the outer sealing profile. The drain cap 62 has a flange 63 arranged in a mounting channel 39 extending in the longitudinal direction of the elastic sealing strip. Respective first and second vent openings 55 of respective first and second vertically extending drain channels 18, 19, 34, 35 formed on the first and second side, respectively, of a vertically extending seal carrier profile 6, are provided with a common vent cap 64 mounted on said vertically extending seal carrier profile 6. At said vent openings 55, the outer sealing profile 33 is cut away locally, and the common vent cap 64 is mounted on the outer sealing profile 33 just above the opening formed by cutting away part of the outer sealing profile 33. The vent cap 64 has a flange 65 arranged in a mounting channel extending in the longitudinal direction of the elastic sealing strip. According to the method according to a described invention of mounting a curtain wall, a number of frames 2, 3 are arranged adjacently to each other in at least two horizontally extending rows of frames positioned on top of each other, each frame 2, 3 including an upper frame member, a lower frame member, a first side frame member and a second side frame member, and each frame surrounding a window 4 or door or other wall element, and each frame being provided with a peripherally extending groove 5. Adjacent frames are sealed against each other by means of a frame sealing system 1 as described above, whereby the first sealing strip 8, 9 is being brought to seal against a first frame 2 and the second sealing strip 11, 12 is being brought to seal against a second frame 3. Each seal carrier profile 6 is connected to the respective first frame 2, 3 after the frame has been arranged in the curtain wall, whereby the seal carrier profile is mounted on the first frame by means of a least to locator blocks 13 connected to the seal carrier profile 6 and spaced in the longitudinal direction L of the seal carrier profile 6 by bringing the first flange 15 of the first side 14 of each locator block 13 into engagement with the peripherally extending groove 5 of the first frame 2, and whereby the respective second frame 3 is subsequently arranged in the curtain wall, thereby bringing the second flange 17 of the second side 16 of each locator block 13 into engagement with the peripherally extending groove 5 of the second frame 3.

In an embodiment of the method, when a first row of frames 2, 3 has been mounted, a through going horizontal seal carrier profile 6 is arranged on top of the first row of frames so that the horizontal seal carrier profile extends from side to side of the curtain wall, and a second row of frames is arranged on top of the horizontal seal carrier profile. Before arranging the second row of frames, the horizontal seal carrier profile is levelled by means of inserting wedges or the like below it, if necessary.

The frame sealing system according to a described invention may be produced in differ- ent sizes in order to fit different types and sizes of frames. In particular, the thickness of the space between adjacent frames may vary according to frame type and size. The seal carrier profiles 6 may to a large extent be of the same type for different types of frames, because the sealing strips may take up tolerances, whereby the locator blocks may suitably be formed in different sizes. Special locator blocks may also be made wherein one side of the block fits one size or type of frame and the other side of the block fits another size or type of frame. This may be used, if two different sizes or types of frames a but each other. Each size may be produced in a specific colour, so that workers on a building site may easily pick the correct locator blocks. The frame sealing system according to some of the described inventions makes sealing easy on the building site in that all sealings may be built into the frame sealing system 1 in the form of dry sealings as illustrated and described above. Nevertheless, additional sealings may be provided, for instance in the form of a wet sealing joint as illustrated in Figs. 8 and 10.

Fig. 46 and 47 illustrate a frame sealing system 101 according to a described invention, adapted to mutually position and mutually seal a first frame 102 and a second frame 103 arranged adjacently to each other. Each frame surrounds a window 104 or door or other wall element and is provided with a peripherally extending groove 105 as it is common in wooden window frames. However, although the frame sealing system 1 according to this invention may be particularly suitable for wooden frames, it is equally applicable to any other type of frame being provided with a peripherally extending groove, such as frames composed by plastic or aluminium profiles. The frame sealing system includes a seal carrier profile 106 having a longitudinal direction L, as indicated in Fig. 59. Furthermore, as seen in Fig. 61, the seal carrier profile 106 has an inner face 120, an outer face 121, a first side 107 and a second side 110. As illus- trated in Figs. 46, 56 to 58 and 61, the first side 107 is provided with a first sealing strip 108 adapted to seal against the first frame 102 and the second side 110 is provided with a second sealing strip 111 adapted to seal against the second frame 103. As particularly illustrated in Figs. 57 and 58, the first side 107 of the seal carrier profile 106 is provided with a first recess 109 in which the first sealing strip 108 is mounted and the second side 110 of the seal carrier profile 106 is provided with a second recess 112 in which the second sealing strip 111 is mounted. Each first and second sealing strip 108, 111 is made of a deforma ble adhesive material adapted to adhere to the respective frame 102, 103. The deformable adhesive material is a rubber adhesive based on natural or synthetic rubbers. Preferably, the deformable adhesive material is an adhesive butyl rubber, sometimes just called "butyl". A suitable butyl is for instance available from the company Dafa. Adhesive butyl ru bber has low temperature-sensitivity and adheres very well to many different materials. Alternatively, the deformable adhesive material may be an acrylic adhesive.

Furthermore, at seen in Fig. 46, the frame sealing system 101 is provided with a first flange 115 adapted to engage the peripherally extending groove 105 of the first frame 102 and a second flange 117 adapted to engage the peripherally extending groove 105 of the second frame 103.

Each first and second recess 109, 112 has a width W and a depth D as indicated in Fig. 57. In a preferred embodiment, in the unmounted position of the frame sealing system 101 illustrated in Fig. 57, each of the first and second sealing strips 108, 111 fills its cor- responding recess 109, 112 only partly in a direction of the width W of the recess and protrudes from the recess, in a direction of the depth D of the recess, by a distance corresponding to at least 1/2 of the depth of the recess and preferably corresponding to at least the depth of the recess. As further indicated in Fig. 57, each of the first and second sealing strips 108, 111 is provided with a release liner 100 to be removed before adhe- sion to the respective frame 102, 103. Thereby, it may be avoided that the deformable adhesive material collects dust or particles which could degrade the adhesive properties of the sealing strip. Furthermore, handling of the seal carrier profile 106 may be facili- tated in that the adhesive properties of the deformable adhesive material may be released only when the seal carrier profile is correctly positioned. The release liner 100 may prevent that, during handling, the deformable adhesive material adheres to other items than intended.

When the seal carrier profile 106 is mounted on a frame, as illustrated in Fig. 46, the deformable adhesive material making up the sealing strip 108, 111 is deformed in that it is pressed flat to a thickness corresponding to the depth D of the corresponding recess 109, 112 so that it is flush with the respective first or second side 107, 110 of the seal carrier profile 106 in which the corresponding recess 109, 112 is formed, and so that the deformable adhesive material at least substantially fills up the recess and thereby adheres to the respective frame 102, 103 over at least substantially the entire width W of the recess. Thereby, a suitable large contact area between the deformable adhesive material and the frame may be ensured, and a suitable initial contact pressure may be created between the deformable adhesive material and the frame, thereby ensuring that good adhesion is subsequently achieved. Fig. 58 illustrates the seal carrier profile 106 in its mounted position (shown isolated from its surroundings), wherein the sealing strips 108, 111 have been pressed flat. As seen in Figs. 46, 57 and 58, each first and second recess 109, 112 of the seal carrier profile 106 is spaced from the inner face 120 and opens through the outer face 121. Thereby, it may be prevented that the deformable adhesive material flows to the inside of the seal carrier profile 106, but still the deformable adhesive material may be able to expand in the recess 109, 112 when the seal carrier profile 106 is mounted on a frame 102, 103, and excessive material may possibly escape from the recess through the opening in the outer face 121.

As illustrated in Figs. 46 and 56 to 58, the outer face 121 of the outermost seal carrier profile 106 is provided with an elastic gasket 122 mounted thereon and adapted to mu- tually seal the first and second frames 102, 103 against each other and thereby form outer first and second drain channels 118, 119 between said adjacent frames. The elastic gasket 122 provides a primary seal in front of the seal carrier profile 106 so that any water leaking through said primary seal may be drained away by means of the outer drain channels 118, 119. Thereby, the risk of any water reaching the seal carrier profile 106 itself may be substantially reduced. Because of the elastic gasket 122 in front of the seal carrier profile 106, the pressure of any water reaching the seal carrier profile 106 may be substantially reduced. Because the sealing properties of the seal carrier profile 106 provided with the deformable adhesive material may indeed by very good, the risk of any water entering through both the primary seal in the form of the gasket 122 and the secondary seal in the form of the seal carrier profile 106 may be very little. In the illustrated embodiment, the elastic gasket 122 has a first side 126 and a second side 127 separated by a wall 128 of the gasket 122. The first side 126 of the gasket 122 is provided with a first outer sealing lip 129 and a first inner sealing lip 130 spaced from each other and both adapted to seal against the first frame 102 to form the first drain channel 118, and the second side 127 of the gasket 122 is provided with a second outer sealing lip 131 and a second inner sealing lip 132 spaced from each other and both adapted to seal against the second frame 103 to form the second drain channel 119. Thereby, the gasket 122 may create a double sealing effect in that both the outer sealing lips 129, 131 and the inner sealing lips 130, 132 seal against the respective frames. Furthermore, because the gasket 122 forms a first drain channel 118 and a second drain channel 119 which are separated from each other by means of the wall 128 of the gasket 122, an even better sealing effect may be obtained. In this way, any water possibly reaching one of the first or the second drain channels 118, 119 may immediately be drained away without reaching the opposed frame. Thereby, the risk that any water having reached one of the drain channels could leak into the building is further reduced.

Furthermore, referring to Figs. 5 and 6, in an embodiment, the frame sealing system 101 includes at least two locator blocks 113 adapted to abut the seal carrier profile 106 so that the locator blocks 113 are spaced in the longitudinal direction L of the seal carrier profile 106. Comparing Figs. 48, 49 and 50, illustrating the same embodiment including a horizontally extending seal carrier profile 106, it may be understood that at some positions along the length of the seal carrier profile 106, locator blocks 113 are arranged between the frames 102, 103 as seen in Fig. 48, and at other positions along the seal carrier profile 106, frame packers 171 are arranged between the frames 102, 103 as seen in Fig. 50. At the positions of the frame packers 171, the adjacent frames 102, 103 may be fixed together by means of frame screws 172. Fig. 51 illustrates a view from the left of Fig. 50; however, the locator blocks 113 are not illustrated in Fig. 51. Further- more, it may be understood that at some positions along the length of the seal carrier profile 106, frame mounting brackets 173 are arranged between the frames 102, 103 as seen in Fig. 49.

Referring again to Figs. 5 and 6, each locator block 113 has a first side 114 being provid- ed with a first flange 115 adapted to engage the peripherally extending groove 105 of the first frame 102 and a second side 116 being provided with a second flange 117 adapted to engage the peripherally extending groove 105 of the second frame 103. Furthermore, the first side 114 of each locator block 113 is provided with two elastic grip- pers 123 adapted to abut a first side wall of the peripherally extending groove 105 of the first frame 102. Thereby, when the locator block 113 has been positioned on the first frame 102 with its first flange 115 engaging the peripherally extending groove 105 of the first frame 102, the elastic grippers 123 may ensure that the locator block 113 does not move when the seal carrier profile 106 is subsequently brought into abutment with the locator block 113 and mounted on the first frame 102, and when the second frame 103 is positioned adjacent the first frame 102 and the second flange 117 of the locator block 113 is brought into engagement with the peripherally extending groove 105 of the second frame 103. As seen, the elastic grippers 123 of each locator block 113 are arranged between two spaced flanges forming the first flange 115 of the locator block. As described above, the locator block 13, 113 illustrated in Figs. 5 and 6 is further provided with first and second opposed ends 24, 25 each being provided with a first type of snap lock part 26 formed by elastic grippers 30. However, the embodiment of the locator blocks 113 used for the inventions illustrated in Figs. 45 to 90 are generally not provided with snap lock parts at its first and second opposed ends. Rather, as mentioned above, the at least two locator blocks 113 are adapted to abut the seal carrier profile 106. This embodiment of the locator blocks 113 may be preferred for seal carrier profiles made of wood or wooden materials. Nevertheless, of course, the locator blocks 113 used for the inventions illustrated in Figs. 45 to 90 could be provided with snap lock parts 26 at its first and second opposed ends 24, 25, as illustrated in Figs. 5 and 6. In fact, also other types of snap lock parts or interlocking structures could be employed. For instance, the seal carrier profiles 106 may be provided with a tongue or groove fit- ting a corresponding groove or tongue of the locator blocks 113.

Because the locator blocks 113 are separate elements which abut the seal carrier profile 106, the sealing and isolation properties of the continuous seal carrier profile may be optimized independently of the positioning properties of the locator blocks 113, and vice versa. The seal carrier profile 106 can be made with relatively small dimensions so that it does not extend all the way from the inside to the outside of the frames, because it does not need to carry the load of the forces acting between the frames. These forces may be taken up by the locator blocks 113 which act to mutually position the frames 102, 103. The locator blocks, in turn, may be produced as strong as necessary with only very little impact on the sealing properties. Furthermore, the locator blocks 113 may facilitate positioning of the seal carrier profile 106 on the respective frames 102, 103, because the position of the locator blocks 113 is given by the peripherally extending groove 105, and the seal carrier profile may be brought into a butment with the locator blocks during positioning.

Preferably, the seal carrier profile 106 is made of a first material having a first coefficient of thermal expansion and the locator block 113 is made of a second material having a second coefficient of thermal expansion, and the second coefficient of thermal expansion is greater than or substantially greater than the first coefficient of thermal expan- sion. Because the seal carrier profile 106 extends continuously along frame members of the frames 102, 103, the seal carrier profile may preferably be made from a material having a relatively low coefficient of thermal expansion, such as wood. As a result, the length of the seal carrier profiles 106 will only change relatively little as a result of temperature changes and therefore, the change in length may easily be taken up for in- stance by means of an end gasket. Consequently, very good sealing properties may be achieved. Because the locator blocks 113 are separate, discretely arranged elements, which the seal carrier profile 106 only abuts, the material of these may be chosen with- out taking into consideration the coefficient of thermal expansion, that is, a greater coefficient of thermal expansion may be accepted. Consequently, a strong material such as plastic may be used. In any case, in order to not create a thermal bridge, a material having low thermal conductivity may be preferred for the locator blocks 113.

In an alternative not shown embodiment, the first side 107 of the seal carrier profile 106 is provided with the first flange adapted to engage the peripherally extending groove 105 of the first frame 102 and the second side 110 of the seal carrier profile 106 is provided with the second flange adapted to engage the peripherally extending groove 105 of the second frame 103. Thereby, mounting of the sealing system 101 may be facilitated in that the seal carrier profile 106 and the first and second flanges may be mounted on a first frame in one operation.

Fig. 45 illustrates in a purely schematic way a curtain walling system 140 incorporating a frame sealing system 101 as described a bove. The curtain walling system 140 includes a number of frames 102, 103 arranged adjacently to each other and forming a wall or a part of a wall having an outside 141 and an inside 142 as illustrated in Figs. 46 and 47. For the sake of simplicity, the frames 102, 103 are not shown in Fig. 45, but only the intermediately arranged horizontal and vertical seal carrier profiles 106 are indicated. In the embodiment illustrated in Fig. 45, the frames are arranged in three horizontally extending rows of frames, wherein each row is formed by four frames. The rows of frames are positioned on top of each other, and each frame includes an upper frame member, a lower frame member, a first side frame member and a second side frame member, wherein each frame 102, 103 surrounds a window 104 or door or other wall element. The adjacent frames in each row are sealed against each other by means of a vertically arranged seal carrier profile 106 as described above, and the rows of frames are sealed against each other by means of a horizontally arranged seal carrier profile 106 as described above. Each horizontally extending seal carrier profile 106 arranged between two horizontally extending rows of frames positioned on top of each other is formed by one or more profiles arranged end to end, preferably via a sealing strip, thereby forming a through going horizontal seal carrier profile 106 extending from side to side of the curtain walling system 140. Each vertically extending seal carrier profile 106 is arranged between two adjacent frames 102, 103 and has a length corresponding at least approximately to the height of said adjacent frames and abuts any horizontally extending seal carrier profile 106 arranged just above and/or just below said vertically extending seal carrier profile 106. The vertically extending seal carrier profiles 106 abut the horizontally extending seal carrier profiles 106 via upper and lower sealing strips, respectively, as illustrated in Figs. 56, 59 and 60. As seen, these sealing strips are mounted as one length of sealing string attached about the entire perimeter of the vertically extending seal carrier pro- files 106 and thereby also forming the first and second sealing strips 108, 111. In addition, as seen in Fig. 65, the horizontally extending seal carrier profiles 106 are also provided with sealing strips mounted as one length of sealing string attached about the entire perimeter of the horizontally extending seal carrier profile 106 and thereby also forming the first and second sealing strips 108, 111 of the horizontally extending seal carrier profile 106. Therefore, the sealing strips of the horizontally extending seal carrier profiles 106 also form part of the upper and lower sealing strips by means of which the vertically extending seal carrier profiles 106 abut the horizontally extending seal carrier profiles 106. As mentioned above, the locator blocks 113 abut the seal carrier profile 106. Thereby, during installation of the curtain wall, the locator blocks 113 may facilitate positioning of the seal carrier profile 106 on the respective frames, because the position of the locator blocks is given by the peripherally extending groove 105, and the seal carrier profile may be brought into abutment with the locator blocks during positioning.

As illustrated in Figs. 46, 48 and 50, corresponding seal carrier profiles 106 may be arranged on opposed sides of the locator blocks 113. Thereby, further improved sealing properties may be achieved. Alternatively, such inner seal carrier profile 106 may be replaced by means of a joint of elastic sealant 135 mutually sealing the first and second frames 102, 103 against each other, as seen in Fig. 47. In the curtain walling system illustrated in Fig. 45, as seen in Fig. 46, the first side 107 of the seal carrier profile 106 is provided with a first recess 109 in which the first sealing strip 108 is arranged and the second side 110 of the seal carrier profile 106 is provided with a second recess 112 in which the second sealing strip 111 is arranged, and each first and second sealing strip is made of a deformable adhesive material adhering to the respective frame 102, 103. The first side 107 of the seal carrier profile 106 abuts the first frame 102 and the second side 110 of the seal carrier profile 106 abuts the second frame 103. As further seen in Fig. 46, when comparing with Fig. 58, the outer elastic gasket 122 has an inner face 133 facing the outer face 121 of the seal carrier profile 106 and an opposed outer face 134, and the outer face 134 of the outer elastic gasket 122 is covered by a joint of elastic sealant 135 or a so-called wet sealing joint mutually sealing the first and second frames 102, 103 against each other. The joint of elastic sealant 135 may create a further sealing barrier against water. Thereby, even better sealing properties may be achieved.

As illustrated in Figs. 48, 49 and 50, at horizontally extending and adjacent frames 102, 103, the upper frame 2 may be provided with stacker flashing in the form of a drip nose element 143 shielding the joint of elastic sealant 135 from rain. The drip nose element 143 is mounted by means of a number of holders 174 for the drip nose element 143 as illustrated in Figs. 74 to 76. The holder 174 for the drip nose element is provided with a screw fixture 189 holding the mounting screw 191 in place during mounting. As the mounting screw 191 is tightened, the screw fixture 189 breaks off the holder 174.

As illustrated in Figs. 52, 53, 54, 55, 62, 67 and 70, perimeter seal carrier profiles 136, 137, 138 extend along a perimeter 145 of the curtain walling system 140 and are provided with membrane 146 sealing against a wall 147 or the like surrounding the curtain walling system. The membrane 146 is preferably adhered to the wall 147 or the like by means of a suitable adhesive or paste and subsequently also taped to the wall 147 or the like at its edge by means of a suitable tape. A suitable membrane is for instance obtainable from the company Tremco lllbruck. Each perimeter seal carrier profile 136, 137, 138 has a longitudinal direction L, a frame contacting face 150 abutting one or more frames 102, 103 and a membrane contacting face 151 to which the membrane 146 is adhered. In the illustrated embodiments, the frame contacting face 150 and the membrane contacting face 151 extend at right angles and are arranged at either side of a corner of the perimeter seal carrier profile 136, 137, 138, seen in cross-section. However, in alternative embodiments, the frame contacting face 150 and the membrane contacting face 151 could also be arranged differently, for instance at opposed, parallel faces of the perimeter seal carrier profile 136, 137, 138, seen in cross-section. The perimeter seal carrier profiles 136, 137, 138 are fixed to the frames preferably by means of screws 139. The frame contacting face 150 of the perimeter seal carrier profile 136, 137, 138 is provided with a recess 148 in which a perimeter sealing strip 149 is arranged. This recess 148 of the perimeter seal carrier profiles 136, 137, 138 corresponds to the recesses 109, 112 of the seal carrier profiles 106. The perimeter sealing strip 149 is correspondingly made of a deformable adhesive material adhering to the respective frame or frames 102, 103. The deformable adhesive material is a rubber adhesive based on natural or synthetic rubbers. Preferably, the deformable adhesive material is an adhesive butyl rubber, sometimes just called "butyl". Adhesive butyl rubber has low temperature- sensitivity and adheres very well to many different materials. Alternatively, the deformable adhesive material may be an acrylic adhesive.

As for instance seen in Fig. 52, an edge 144 of the membrane 146 is sandwiched between an edge of a metal cover profile 152 and the membrane contacting face 151, and said edge of the metal cover profile 152 is fixed to the perimeter seal carrier profiles 136, 137, 138 preferably by means of screws 153 or nails extending through the mem- brane 146. A perimeter groove 154 is formed between the metal cover profile 152 and the frames 102, 103, and an elastic perimeter gasket 155 is arranged in the perimeter groove 154 and mutually seals the metal cover profile 152 and the frames 102, 103 against each other, thereby forming perimeter drain channels 156, 157 in the perimeter groove 154.

As further seen for instance seen in Fig. 52, the elastic perimeter gasket 155 has a first side and a second side separated by a wall of the gasket 155. The first side of the gasket is provided with a first outer sealing lip and a first inner sealing lip spaced from each other and both sealing against the one or more frames 102, 103, thereby forming a first perimeter drain channel 156. The second side of the gasket 155 is provided with a second outer sealing lip and a second inner sealing lip spaced from each other and both sealing against the metal cover profile 152, thereby forming a second perimeter drain channel 157. Furthermore, the elastic perimeter gasket 155 has an inner face facing the metal cover profile 152 and an opposed outer face, and the outer face of the elastic perimeter gasket is covered by a joint of elastic sealant 135 mutually sealing the metal cover profile 152 and the frames 102, 103 against each other. As it is understood, the elastic perimeter gasket 155 may be similar to the elastic gasket 122 arranged in front of the seal carrier profiles 106 as described above.

As seen in Fig. 53, at the level of the starter profile 169 of the curtain walling system, a metal cill profile 179 is formed by a metal cover profile 152 arranged in a way corre- sponding to that explained above regarding Fig. 52.

As illustrated in Figs. 81 to 84, at corners of the wall or a part of a wall formed by the frames 102, 103 of the curtain walling system 140, the membrane contacting face 151 of the perimeter seal carrier profiles 136, 137, 138 illustrated in Figs. 62, 67, 70 and meet- ing at the corner is provided with a recess 158 in which an elastic corner piece 159 illustrated in Fig. 80 is arranged at least substantially flush with the membrane contacting face 151. Pieces of membrane 146 meeting at the corner are adhered to the elastic corner piece 159. The elastic corner piece 159 may be made of rubber, such as EPDM or any other suitable material. Furthermore, as seen, a metal corner plate 160 illustrated in Fig. 79 is arranged in the recess 158 in the membrane contacting face 151 and sandwiched between a bottom of the recess 158 and the elastic corner piece 159.

As understood from the above, in the curtain walling system 140 illustrated in Fig. 45, adjacent frames 102, 103 are sealed against each other by means of a gasket 122 having a first side 126 and a second side 127 separated by a wall 128 of the gasket 122. The first side 126 of the gasket is provided with a first outer sealing lip 129 and a first inner sealing lip 130 spaced from each other and both sealing against a first frame 102, thereby forming a first drain channel 118. The second side 127 of the gasket is provided with a second outer sealing lip 131 and a second inner sealing lip 132 spaced from each other and both sealing against a second frame 103, thereby forming a second drain channel 119. Thereby, the gasket 122 may create a double sealing effect in that both the outer sealing lips 129, 131 and the inner sealing lips 130, 132 seal against the respective frames. Furthermore, because the gasket 122 forms a first drain channel 118 and a second drain channel 119 which are separated from each other by means of the wall 128 of the gasket 122, an even better sealing effect may be obtained. In this way, any water possibly reaching one of the first or the second drain channels may immediately be drained away without reaching the opposed frame. Thereby, the risk that any water having reached one of the drain channels could leak into the building is further reduced.

The gasket 122 has the form an elastic gasket having an H-shape and being formed in one single piece. Of course, elastic gaskets having other suitable shapes are possible. The elastic gaskets may be made of rubber or synthetic rubber or any other suitable material.

Furthermore, each horizontally extending gasket 122 arranged between two horizontally extending rows of frames 102, 103 positioned on top of each other is formed by one or more gaskets 122 arranged end to end, thereby forming a through going horizontal gasket extending from side to side of the curtain walling system 140, and, in each horizontally extending row of frames, a separate vertically extending gasket 122 is arranged between each pair of adjacent frames 102, 103 and extends between a corresponding upper and lower through going horizontal gasket 122.

Referring to Fig. 50, and as illustrated in Figs. 87 and 88, each horizontally extending gasket 122 arranged between two respective horizontally extending rows of frames 102, 103 positioned on top of each other is provided with a number of drain holes 162 connecting a first and upper drain channel 163 formed by said horizontally extending gasket with a second and lower drain channel 164 formed by said horizontally extending gasket. Thereby, even better drainage of the curtain walling system 140 may be ensured, because any water collected in a first and upper drain channel 163 of a horizontally ex- tending gasket 122 may drain through said drain holes 162 to a second and lower drain channel 164 of said horizontally extending gasket and therefrom, the water may easily drain away into vertically extending drain channels 118, 119. In the case of a through going horizontally extending gasket, said drain holes 162 may ensure that any water not already drained away through drain openings 161 above the through going horizontally extending gasket may continue to drain openings below the through going horizontally extending gasket 122.

As illustrated in Fig. 45, each pair of first and second vertically extending drain channels 118, 119 formed by a common gasket 122 arranged in a first horizontally extending row 165 of frames 102, 103 positioned on top of a second horizontally extending row 166 of frames 102, 103 is associated with a separate drain opening 161 arranged in the second horizontally extending row 166 of frames. Furthermore, as seen in the figure, each pair of first and second vertically extending drain channels 118, 119 formed by a common gasket 122 arranged in a certain horizontally extending row 165, 166 of frames 102, 103 is associated with a separate vent opening 167 arranged in the same horizontally extending row of frames. Furthermore, as seen in the figure, in each horizontally extending row of frames 102, 103, the separate drain openings 161 are arranged between each pair of adjacent frames 102, 103 at the position 168 of the upper frame members of said pair of adjacent frames. Furthermore, as seen in the figure, the separate vent openings 167 are arranged below the respective drain openings 161, and the first and second vertically extending drain channels 118, 119 are blocked between the drain openings 161 and the vent openings 167. As illustrated in Fig. 45, a common drain and vent insert 170 shown in Figs. 56, 71, 72, 86 and 88 forms a common drain opening 161 for a pair of first and second vertically extending drain channels 118, 119 and a common vent opening 167 for a pair of first and second vertically extending drain channels 118, 119. As illustrated in Figs. 56, 59, 60 and 88, the common drain and vent insert 170 is arranged in line with a gasket 122 forming the pair of first and second vertically extending drain channels 118, 119 vented by said drain and vent insert 170. The common drain and vent insert 170 is also provided with sealing strips 184 along the sides of the blocking wall 186 of the drain and vent insert.

Each seal carrier profile 106 is connected to the respective first frame 102, 103 after the frame has been arranged in the curtain wall, whereby, firstly, at least two locator blocks 113 are mounted on the first frame 102 by bringing a first flange 115 of a first side 114 of each locator block 113 into engagement with the peripherally extending groove 105 of the first frame 102, whereby secondly, the seal carrier profile 106 is arranged on the first frame 102 so that it abuts the at least two locator blocks 113 and so that the locator blocks are spaced in the longitudinal direction L of the seal carrier profile 106, and whereby thirdly, the seal carrier profile 106 is preferably fixed to the first frame 102 by means of nails or screws, and whereby the respec- tive second frame 103 is subsequently arranged in the curtain wall, thereby bringing a second flange 117 of a second side 116 of each locator block 113 into engagement with the peripherally extending groove 105 of the second frame 103. The seal carrier profile 106 may simply stick to the first frame 102 only by means of the first sealing strip 108, in the case that this is made of or includes an adhesive, and in this case, separate fixing means such as nails or screws may not be necessary.

In an embodiment of the method, when a first row 166 of frames 102, 103 has been mounted, a through going horizontal seal carrier profile 106 is arranged on top of the first row 166 of frames so that the horizontal seal carrier profile extends from side to side of the curtain wall, and a second row 165 of frames is arranged on top of the horizontal seal carrier profile 106.

The frame sealing system 101 according to a described invention may be produced in different sizes in order to fit different types and sizes of frames. In particular, the thickness of the space between adjacent frames 102, 103 may vary according to frame type and size. Accordingly, the seal carrier profiles 106 may be formed in different sizes. Special locator blocks 113 may also be made wherein one side of the block fits one size or type of frame and the other side of the block fits another size or type of frame. This may be used, if two different sizes or types of frames abut each other. Each size may be produced in a specific colour, so that workers on a building site may easily pick the correct locator blocks.
