The first adhesive connection (33) is achieved in an advantageous manner by an adhesive strip and the second by a liquid adhesive material.

Description

window

Field of the invention

The present invention relates to a sash according to the preamble of claim 1, a window system according to the preamble of claim 12 or 22, and a method for its production.

State of the art

In conventional wood, metal or plastic windows, the glazing, consisting of two or three panes, is usually held by the casement frame. The sash extends inside and outside the edge of the glazing so that the glazing is firmly engaged by the frame.

Recently, windows have come on the market, in which the glazing is additionally glued to the sash. However, these adhesive bonds are always used in combination with other form-fitting frame / window connections. Windows with glued joints between glass and sash are usually metal windows. One reason for this is likely to be that the adhesives used are mixed with other materials, e.g. Wood, does not guarantee a reliable and long-lasting connection. As an adhesive, a silicone-based adhesive is used in the mentioned windows, which still has a certain elasticity in the cured state.

In recent years, more and more outwardly opening windows have been used in house construction. In the context of the present invention, an outwardly opening window is to be understood as meaning a file, in which the window is pivoted for opening about a horizontal pivot axis and the pivot axis is thereby moved away from the casement. To the outside

I open windows have the advantage that when the window is tilted fresh air

Bestätigungskopli flows quickly and in large quantities into the room. It is also an advantage that the open window sash does not protrude into the room and takes up space. As far as design is concerned, outward-opening windows are preferred by the architects for their filigree design. Through the use of stepped glass, it is also possible to cover the sash frame, so that such windows can be used for example in full glass facades. A disadvantage of the commercially available, outwardly opening windows is often their complicated structure and the associated high price.

From the company Raico Bautechnik GmbH, Pfaffenhofen, Germany under the trade name "Raicowing" a hinged window is offered, which opens to the outside.The above mentioned folding window has a metal sash and a frame made of extruded aluminum profiles on the wing frame is adapted to the metal frame Locking system provided.

US Pat. No. 6,055,783 teaches the manufacture of a sash wherein the glass sheets are incorporated directly into a frame construction without first producing an insulating glazing. It can be dispensed with the use of separate spacers for the glass. This is accomplished by employing a support structure having a first receiving surface to secure the outer edge of the outside of a first glass sheet thereto, and having a second receiving surface to secure the outer edge of the inside of a second glass sheet thereto do. Both glass panes are only supported by these receiving surfaces.

NL-A-9300377 discloses a window or door structure consisting of a frame and an insulating glazing of two panes connected to the frame. The insulating glazing is a so-called stepped glass, in which the outer window pane is larger than the inner window pane. Of the Frame has a stepped rebate, in which the stepped glass is inserted. The Stufenηglas is connected by a single adhesive joint, which is located between the outer window and the front side of the frame, with the latter. The frame of the window can be made of wood. To protect the adhesive bond from sunlight, the outer glass pane is either internally or externally coated with an enamel layer. NL-A-9300377 does not give details of the window construction and does not indicate suitable adhesives.

DE-A-101 32356 relates to a glass sliding cover or a glass door with a frame enclosing the glass pane, wherein the glass pane is glued to the frame. The gluing of the frame and the glass pane takes place by means of a jelly-like adhesive tape. This has the advantage that the splices are sufficiently clean and therefore need not be obscured for visual reasons.

German utility model DE-U-20010289 relates to a window or door frame with an insulating glazing provided on the outside of the frame, which is connected exclusively by gluing to the casement. The outer pane of the insulating glazing projects in front of the inner pane on all sides, so that a stepped rebate is formed. The stepped rebate of the insulating glazing is inserted into a frame rebate provided on the outside of the frame. To attach the glazing to the frame legs serve mounting rails, which are glued to the edge on the inside of the outer pane. The mounting rails have an undercut groove, can engage in the rotatable hammerhead-like clamps. The clamp closures are fastened to the frame profile. The insulating glazing is thus connected via the fastening rails and the clamp closures with the frame profile. A direct adhesive bond between the glazing and the frame does not exist. task

The object of the present invention is to propose a window opening in particular outwards, in particular a wooden window, and a method for the production thereof, which are inexpensive. Another aim is to provide a window which has a high insulation value. Another goal is to provide a window that is very appealing to the design. In addition, the window by its construction and design, even for high mechanical and structural requirements is ideal.

A window sash according to the preamble of claim 1 is characterized according to the invention in that the sash frame is essentially formed by an L-shaped profile having a first and a second leg, the first legs of opposite frame profiles being oriented towards each other, and the step glazing being oriented towards one another Adhesive connection is connected to the L-profile. A characteristic of the window sash according to the invention is that the inner window pane of the step glazing is fixedly connected to the first leg of the sash frame profile on its outside by an internal adhesive bond. This contributes to a high rigidity and torsional strength of the window. The inner adhesive bond is exposed to lower temperature fluctuations than the outer one

Adhesive bond. The internal adhesive bond can therefore have a lower elasticity than the outside, which leads to an increase in the connection stiffness between sash and glazing.

The selected connection technology, it is also possible to build a structurally very simple window, which is inexpensive to produce. Compared to conventional windows, the new design eliminates wedging of the glazing in the casement. Also, it is not necessary that the sash forms a positive connection with the glazing. Advantageously, the inner window pane is firmly connected to the first limb of the L profile by means of an adhesive connection which has a lower elasticity than the outer adhesive connection. In a stepped glass, the outer pane has a projection relative to the inner pane. Through the use of the stepped glass window, the frame is invisible from the outside, which is particularly appreciated by architects. Between this frame and the outer window of the stepped glass is advantageously an adhesive connection with a _. compared to the inner adhesive bond higher elasticity available.

Different elasticities can be achieved by the choice of material of the adhesive and by the layer thickness of the adhesive.

As a standard bonding, one with a more flexible adhesive can be considered. This offers over less flexible adhesives an improvement in the sound insulation of the window system. This adhesive is defined by the tensile shear strength, which is in a range of 1 to 3 MPa.

For increased tensile shear strength requirements of the adhesive bond, a less flexible adhesive may alternatively be used. Such adhesives have a tensile shear strength in the range of 9 to 12 MPa. Their elasticity is classified with Shore hardness A 90 and D 50. For special applications and special solutions, adhesives with even higher tensile shear strengths can be used.

Advantageously, the adhesive bond, in particular the outer, formed by a heat-reactive polyurethane adhesive, or preferably by an acrylate reaction adhesive. The use of a heat-reactive polyurethane adhesive has the surprising advantage that it is possible to produce such stable and strong hollow glass compounds. According to a preferred

Embodiment is the adhesive connection, in particular the inner, by a double-sided adhesive tape formed. The double-sided adhesive tape has the advantage of comparatively easier handling than liquid adhesive. With an adhesive tape, an extremely clean-looking adhesive bond in constant quality can be achieved. In addition, there are adhesive tapes, which in terms of adhesive strength and durability are in no way inferior to the liquid adhesives. According to an advantageous embodiment, the adhesive tape is made of a foamed plastic, for example polyurethane or silicone. On both sides of the foamed plastic tape suitable adhesive layers, for example based on acrylate, may be applied.

Advantageously, the edge of the outer window pane is provided with an opaque layer or coating at least in the region of the at least one adhesive bond. As a result, aging or damage to the adhesive bond can be avoided by UV radiation. According to a particularly advantageous embodiment, the step glass is fixedly connected to the first leg by means of a first, less elastic adhesive bond and to the end face of the second leg of the L profile by means of a second, more elastic adhesive bond. This creates a particularly stable bond between the stepped glass and the casement. It can be dispensed with additional fastening means for fixing the window glass on the frame. The relatively rigid internal adhesive bond also allows to manufacture the sash made of profiles with very small cross-sections, since the sash obtained by glued glazing stability.

Along the inner window pane extends an end edge of the first leg of the sash profile. Between this end edge and the window pane, a fold is expediently provided, in which a sealing strip is accommodated. This ensures a good seal of the window to the room side. However, this seal may be obsolete with a suitable choice of adhesive bond. Advantageously, the folding depth defined by the L-profile is smaller than the thickness of the stepped glazing composed of a plurality of window panes minus the thickness of the outer window pane. This is between the face of the. second gap and the projecting edge of the step glazing, a gap is present, which is filled with an adhesive to form the second, outer adhesive bond. The filled adhesive forms a thicker and therefore tend to be more elastic adhesive layer than the inner adhesive bond.

Conveniently, between the leg of the L-profile and the step glazing still existing space is filled with an insulating material. As a result, a cold bridge in this area can be avoided. This space may also be vented to facilitate moisture balance with the environment.

The inventive structure of the window is particularly suitable in

Connection with a wooden or plastic frame. The plastic frame can be reinforced by metal profiles. The window sash can be hinged to a window frame in a known manner by means of window fittings pivotally. Preferably, the length and width of the window frame are substantially the same as the length and width of the outer window pane. This has the advantage that the window fittings are protected from the weather.

Advantageously, the window frame is formed by an L-shaped window frame profile. This is a cost-effectively producible frame. Between the soffit of the L-shaped frame profile and the L-shaped sash profile, there is expediently a space in which the window fittings are accommodated.

According to a particularly preferred embodiment, a projection of the outer window pane strikes in the closed position on the end face of the L-shaped window frame profile. This creates a window system which can be fitted with little effort in a Mauerlebubung. Conveniently, a sealing web is provided on the inside of the supernatant. This ensures a good seal of the window. On the window pane oriented side of the base leg of the frame profile grooves are preferably provided for receiving sealing strips. These seals can be simple in design and therefore inexpensive.

A preferred embodiment provides that the inner sash framing is aligned with the inner reveal of the window frame. As a result, furthermore, the casement is concealed by the window frame when the window is closed. This also opens up new possibilities in terms of design. The fact that the light of the frame, sash, and optionally also the light of the step glazing, are identical, results in a very attractive appearance. This clear width of the window can thereby be maximally large compared to the clear width of the wall opening in which the window system is installed.

The present invention also provides a method for producing an outwardly opening window by the following method steps: a) providing a cross-sectionally L-shaped sash profile with a first and a second leg, wherein the first legs of opposite frame profiles are oriented against each other, and b) a step glazing which fits into the sash frame profile and has at least two window panes arranged at an inner and an outer spacing and c) producing at least one continuous glued connection between the step glazing and the sash profile, in particular a circumferential inner glued connection between the outer surface of the sash inner window pane and the first leg and an outer adhesive connection between the inside of the outer window pane and the second leg of the sash frame profile. The inner adhesive bond advantageously has a lower elasticity than the outer adhesive bond.

The inventive method for window production is extremely simple and time-saving. In this case, the adhesive is preferably applied to the window-oriented side of the first and the second leg of the L-profile. To the surprise of the inventors, it has been found that a very stable and torsionally rigid window is obtained, since the strength of the glass used contributes substantially to the stability of the window. Further advantageous variants of the method are defined in the subclaims.

Another variant of the production method is characterized by the following method steps: a provision of a cross section L-shaped sash profile with a first and a second leg, wherein the first legs of opposite frame profiles are oriented against each other, and one in the frame matching step glazing with at least two, one inner and an outer, spaced-apart window panes, wherein the outer window pane has a protruding edge relative to the inner window pane; b applying an adhesive, in particular an adhesive tape, on the first leg of the L-shaped profile to produce a first

Glued connection, c inserting the step glazing into the frame; and d introducing a second adhesive layer between the end face of the L-profile and the edge of the outer window pane to produce a second one

Adhesive bond.

Alternatively, the adhesive may also be applied to the glass before the step glazing is inserted into the frame. An expedient variant provides that the profile with the inserted stepped glass is arranged approximately horizontally for drying and curing of the adhesive layers. Due to the weight of the step window glass can be dispensed with additional weighting of the window during drying. Conveniently, the adhesive surfaces of the frame and the step glass are previously coated with a primer. This ensures a good connection of the adhesive on the one hand with the glass and on the other hand with the sash.

The present invention is also a window system with an outwardly opening, in particular tiltable window with a sash and a window received in the sash and a frame on which the window is hinged in the installed state about a horizontal axis, which is characterized in that the window on at least two opposite sides one over the

Fϊügelrahmen protruding supernatant and that the supernatant with the closed window sealingly rests on the frame. This window system is fundamentally independent of the design and structure of the window. The fact that the supernatant abuts the window frame, the frame and arranged between the window frame and the window fittings are completely protected from the weather. Advantageously, as window glazing a stepped glazing with at least two, an inner and an outer, spaced-apart windows used, and the supernatant is formed by the outer window glass (4-sided step glass).

Advantageous developments of the window system are defined in the subclaims.

Exemplary embodiments of the invention will be explained in more detail below with reference to figures. It shows: 1 shows a vertical section of a first exemplary embodiment of a window system according to the invention mounted in a wall reveal with a step glazing;

The window system 11 according to the invention shown in FIGS. 1 to 2 has a sash 12 in a frame 41. The window sash 12 has a sash frame 13 and a stepped glazing 15 inserted into the sash frame. The stepped glazing consists in the exemplary embodiment shown of an inner window pane 19, a middle window pane 21 and an outer window pane 23, between which spacers 24 are arranged. In the present invention, step glazing is a window glazing consisting of two or more window panes, in which the outer window pane projects beyond the inner window pane

Edge 16 has. The protruding edge 16 is formed on at least three sides of the window, but preferably on all four sides of the window. The individual windows 19,21 and 23 are separated by spacers 24 from each other ^'and fixedly connected thereto. The spaces between the windows can, as is known in high-quality windows, be filled with a noble gas.

The sash frame 13 consists essentially of an L-shaped Flügelrahmenprof il 25 with a first leg 27 and a standing perpendicular to the first leg 27 second leg 29. The step glass 15 is located on the one hand with the inner window 19 on the multi-glazing side oriented towards first leg 27 and on the other hand with the outer window 23 on the outwardly oriented end face 31 of the second leg 29 at. The connection between the step glazing 15 and the wing frame 13 by means of a suitable adhesive. Such adhesives are commercially available. A first adhesive bond 33 between the inner window pane 19 and the first leg 27 may be made by a flowable adhesive or a double-sided adhesive tape. A second adhesive bond 35 is located between the outer window pane 23 and the end face 31 of the leg 29. To produce this outer adhesive bond 35, a suitable flowable adhesive is preferably used. Such adhesives are also commercially available.

By the adhesive bonds 33,35 a solid bond between the step glazing 15 and the sash 13 is provided. The mechanical stability of the stepped glazing 15 substantially contributes to the stability of the (composite) window. It is the glazing, which gives the wing frame 13 stability over the adhesive bond. Due to the novel approach, it is the Inventors managed to create a high-quality window system with a very simple and therefore cost-effectively producible sash profile 25, which can be used, for example, in low energy houses.

In order to protect the adhesive bond 35 from the action of the sunlight, a non-transparent coating 37 may be applied to the edge 16 of the outer window glass 23 at least in the area of the bond. The coating can be applied outside or preferably inside on the window glass surface. It is also conceivable to stick outside a non-transparent material web.

To avoid a cold bridge, the intermediate space between the window panes 19, 21 of the stepped glass 15 and the leg 29 of the casement 13 can be filled with an insulating material 38. The insulating material can in liquid or free-flowing form through a filling opening 40 in

Casement profile 25 are filled. A provided in the first leg 27 of the sash profile 25 fold 34 serves to receive a sealing tape 36th

The window sash 12 is articulated in the reveal 39 of a window frame 41. The frame 41 consists of a cross-sectionally L-shaped frame profile, which is fitted into a wall reveal 43 of a house wall 44. Of the . Frame 41 consists of a base profile 45 and arranged on the base profile reveal plate 47. On the side facing the window sash side of the base profile 41 smd two spaced grooves 49,51 provided in which seals 53,55 are added. When the window system 11 is closed, the seals 53, 55 lie sealingly against the chamber-side-oriented side 57 of the first leg 27 of the casement profile 25. It is also conceivable to arrange the seals 53, 55 on the first leg 27. At least one further seal 59 is provided between the outer window pane 23 and the outwardly oriented end face 61 of the reveal plate 47. This seal 59 is preferably arranged on the inside of a projection 17 of the outer glass pane 23 via the casement 13, but could also be fixedly arranged on the reveal plate 47.

Between the frame framing 39 and the casement 13 there is a gap 63, in which window fittings, not shown, are accommodated. The window fittings allow the window sash to open outwards. In this case, the window fittings may include additional functions, and allow, for example, a lowering and turning of the window sash 12.

The window system 11 with the frame 41 may be fitted in a wall reveal 43 in a manner known to those skilled in the art. Usually, an insulating layer 65 is provided between the frame 41 and the house wall 44. This insulating layer 65 may be sealed inwardly and outwardly by an elastic sealing material 67.

^■ Window fittings arranged on the window frame 41 (not shown in the figures) allow the locking of the window fixture 12 in the closed position.

Preferably, fittings are used, which allow at least the underside and top side, possibly even an all-round locking of the window (fittings with so-called. Ecklagern for eckumlaufende closures). A provided on the sash frame 13 pivot lever 14 allows to operate the locking mechanism:

The embodiment of Figure 3 differs from the example according to Figure 2, characterized in that as adhesive seals continuously foamed, z. B. from Silikorvschaum existing seals 89 a, 89 b, are used. Such

Seals have the advantage that they have a low heat conductivity and so that they are good insulation. The seal 89a is applied on the multi-pane side facing the first leg 27 (first adhesive joint 33) and the seal 89b on the outwardly oriented end face 31 of the second leg 29 (second adhesive joint 35). The seals 89 a, 89 b are glued to the wood of the sash frame 13. For this purpose, adhesive layers of suitable adhesives can be applied to the seals.

In the figures 4 and 5, a third embodiment is shown, in which a double Isolierver glass, also a Stuf enver glazing 15, is provided in the sash 12. The frame 61 has in this example embodiment (as in the other embodiments) a base profile 45 made of wood. However, the reveal plate 47 is made of a plastic profile. The plastic profile of the reveal plate 47 has all the necessary mass of the frame, with the exception of the groove 51 for the sealing profile 55. The base profile 45 must therefore have only this groove 51 and be tailored to the plastic profile. For stable assembly of plastic profile reveal plate 47 and base profile 45, a cutout 71 is provided in the base profile. This cutout 71 has a U-shape, which engages in a channel-like portion of the reveal plate 47.

The first dimension of the base profile 45 between Soffit plate and frame light of the frame as well as the second dimension of the base profile 45 between the seal to the sash 12 and the room side of the frame 41 are adaptable to the particular installation conditions and wishes. The first

Dimension may be less than shown in order to a) obtain a paragraph between the frame light of the frame and the sash, or b) put on a trim panel on the frame, which in turn has the same range as the sash. The second dimension can c) end flush with the inside of the wall, leaving a

Wall cladding panel can be performed over the frame. On the Inside the base profile 45, d) a cutout can be present in which such a cladding panel can, for example, be flush or perpendicular to the inside of the window frame. It can also e) relative to the wall reveal a groove be provided to connect the wooden base member 45 via tongue and groove to an adjacent wooden stand or an adjacent wooden frame, for example, another window. Therefore, the base profile can be adapted in a simple manner to the respective conditions and thereby a standard plastic profile (reveal plate 47) are connected to this, which has expediently for the articulation of the window sash 12 mass.

As can be seen in FIGS. 4 and 5, but also in FIGS. 6 and 7, the horizontal deflection plates 47a and the vertical reveal plates 47 are formed differently. In the case of the horizontal soffit panels 47a, the soffit 39 has a planar surface. The front side 61 is formed by a wall which closes a slot 73 open towards the wall reveal. In this slot, a connection plate can be hung.

In contrast, in the case of the plastic profile 47 provided for the vertical arrangement, a guide rail 75 for a turning window fitting is provided behind the end face 61. This guide rail 75 is open to the window sash 12. In this guide rail 75 engage the turning window fitting existing guide means with which the upper end of the sash 12 can be moved from the upper closing position to a lower turning position. Between the guide rail 75 and the channel-like portion, which is screwed to the base profile 45, a jaw web 77 is formed, which is set back both relative to the moistening side surface of the guide rail 75 and against the fitting side opening of the guide rail 75. As a result, the fitting can be fastened to this jaw web 77 with a fastening plate 79 the fitting side of the Leibungsstegs 77 and a counter-plate 81 on the Mauerleibungsseite the Leibungsstegs 77th

As fittings come in addition to turning fittings and rotary door fittings, Senkklappbeschläge and sliding hardware in question. However, it is important to ensure that these fittings do not burden the outer seal or only slightly shearing.

In FIGS. 6 and 7, in contrast to FIGS. 4 and 5, an exemplary embodiment with a triple insulating glazing is shown. All other details are identical. It is noticeable that the same plastic profiles can be used as reveal plates 47 for the triple glazing, as in double glazing. The larger thickness of the glazing is compensated for by cutting out an even bigger fold in the casement profile 25a.

Even in this minimally dimensioned sash profile 25a according to FIGS. 6 and 7, a locking mechanism 83 is accommodated. The locking mechanism 83 is circumferentially formed in a conventional manner, wherein the lateral linkage slightly lower in the sash profile

25,25a are recessed as the linkage in the horizontal sash profiles.

In both embodiments, the glazing consists of stepped glazing. This step glazing 15 has two windows 19 and 23, or three windows 19,21,23. In each case the outer window pane 23 is larger than the other window panes 21, 19. The edge 16 of the outer window pane 23 projecting beyond the blocking and the blockage together have virtually the same dimension as the frame 41. On the inner side of the outer window pane 23, the edge 16 is subdivided into two areas, namely the area of the outer adhesive joint adjoining the blockage 35 with the sash profile 25, and the it Supernatant 17 on the supernatant 17, a sealing profile 59 is glued, which seals in the closed state of the window system 11 against the end face 61 of the soffit 47.

The bonding of the step glazing 15 with the wooden sash 13 has two different adhesive joints 33,35. The inner adhesive bond 33 serves primarily to stabilize the sash frame 13 by bonding it to the angularly rigid inner window 19. It also causes the sash frame, due to the better connection to the glazing, to twist less when locking and manipulating the handle foil 14 and does not come off the inner window. Next, the inner adhesive bond during assembly of a precise fixation of the step glazing 15 on the sash frame 13. This inner adhesive bond 33 is therefore preferably made via an adhesive tape. The adhesive tape ensures a cleanly formed gap between glazing 15 and wing frame 13, since no liquid adhesive can escape from this joint and the adhesive tape can be mounted exactly along the glazing-side edge of the first leg 27 on the sash profile 25. After assembly of casement 13 and step glazing 15, the mutual position of these two parts is fixed immediately, since the adhesive tape bonding requires no drying time or setting time.

The outer adhesive joint 35, however, takes over primarily the forces that act between glazing and sash. This outer adhesive connection 35 is advantageously produced only after the positional fixing of sash frame 13 to step glazing 15. So this second

Adhesive joint 35 can be performed in the desired quality, the second leg 29 of the sash profile 25 is shorter than the step glazing thickness between the outside of the inner window 19 and the inside of the outer window 23. This results in an adhesive gap between the inside of the edge 16 and the end face 31st of the second

Schenkels 29, which is 3 to 6 millimeters wide. A preferred gap width is 4 to 5 millimeters. Such an adhesive gap can be filled from the open narrow side with a viscous adhesive, for example a two-component adhesive. Thanks to the fixation via the first adhesive bond 33, this external adhesive bond 35 may take a certain amount of time to set and harden, without any risk of the glazing moving with respect to the frame during this time.

The outer adhesive bond 35 has been found to be significant with respect to the soundproofing of the window system. For high thermal insulation values, triple glazing is preferred. For high Schalldämrnwerte regardless of the number of panes of the step glazing 15, a relatively soft-setting adhesive in the sweet glue joint 35 is provided. The hardness of the adhesive in Shore is for high sound insulation values at hardness A. An adhesive of hardness A, for example, has a tensile shear strength of 1 to 3 MPa. For applications where higher tensile shear strengths are required, e.g. very large window panes, high wind load, etc. may cause adhesives with higher tensile shear strengths, e.g. 9 to 12 MPa are used. Such an adhesive has, for example, a Shore D hardness. Such a glued window is less sound-absorbing than a glued with softer glue.

The manufacturing method will now be described by way of example with reference to the production of an outwardly opening wood turn window: First, the sash is provided in the form of an L-shaped sash profile 13 with first and second legs 27,29. The frame profiles are arranged so that the first legs of opposite profiles 25 are oriented in a plane against each other. Step glazings are known and can be obtained from appropriate window glass manufacturers in the desired dimension. Both the step glazing and the sash are cleaned at the intended splices and preferably treated with a primer to improve the adhesion of the adhesives. It is also conceivable that Sand the windowpane at the intended splice (sanding strips) to thaw the surfaces and improve adhesion.

The casement is preferably arranged on a horizontal base and applied to the glazing-oriented side of the first leg 27 of the L-profile, a double-sided adhesive tape 33. Then the step glazing is placed in the frame. Alternatively and preferably, the sash frame 13 is placed at a distance from the inner window pane 19 on the step glazing 15, adjusted against this and finally pressed against this. The gap remaining between the end face 31 of the second leg 29 and the inside of the outer window pane is now filled with a flowable adhesive. The splicing point is left to harden for the required time.

Thereafter, the remaining space in the window sash between the

Sash frame and the middle and inner window glass to be filled with an insulating material. Preferably, by means of a filling opening 40 provided in the casement 13, a sprayable or flowable adhesive is introduced, which is also allowed to harden. It has been found that the cavity need not be filled without disadvantage. To prevent

Condensation in the cavity is provided with a vent.
