Definitions

  • the present invention relates to a skylight window for being installed in a roof of a building, the skylight window comprising:
  • Inclined skylight windows are typically built into an opening in an inclined roof structure with an angle above 15 degrees with a substantial part of the inclined skylight window is positioned within the inclined roof structure in an installed position.
  • Flat-roof skylight windows are generally installed on top of the exterior side of flat roofs of buildings, where the inclination of the roof is less than 5 degrees with respect to a horizontal plane of the roof.
  • flat-roof skylight windows are installed to cover an opening in the roof, i.e. a substantial part of the flat-roof skylight window extends above an exterior side of the flat roof structure in an installed position.
  • skylight windows of this type often comprise a dome-shaped weather shield attached to the sash.
  • the weather shield typically follows the movement of the sash.
  • the main purpose of the dome or weather shield is to protect the sash and frame from the weather and to avoid accumulation of precipitation and dirt on the IGU.
  • This roof window comprises a standard VELUX ® outwardly hung window, to the sash of which a dome-shaped weather shield is attached.
  • EP 3 346 071 A1 relates to a window assembly for being mounted in a roof or a celling of a building.
  • the window assembly comprises a window including a window frame arranged to be fixed to the roof or the celling of the building, and wherein the window frame is arranged to suspend a windowpane.
  • EP 3 396 100 A1 relates to a roof window arranged to be mounted in a roof with a sloping pitch of 0-15°, wherein the window comprises: a main supporting frame and/or a sash frame with a glazing unit, and an external screen enabling at least to drain rain water from the window onto the roofing.
  • skylight windows of the prior art may be associated with relatively poor insulating properties and/or limited entry of light into an interior of the building on which the flat-roof skylight window is installed, as well as limited visibility through the window from the interior of the building as well as limited compatibility with different roof angles.
  • This may be attributed to the manner, in which flat-roof skylight windows are installed on a roof structure of a building which generally results in a larger proportion of the window portion structure being exposed to the surrounding environment.
  • a weather shield attached to the top of the skylight there are more layers of glazing which may result in a long travel path for light entering the flat-roof skylight window into the interior of the building.
  • a further object of the invention may be to provide a skylight window with improved light entry and/or in which view through the window is improved.
  • Less material along a peripheral side of the IGU may allow the IGU to be positioned deeper or lower in the window structure, as well as closer to the window frame, which may improve the insulating properties of the skylight as the relative area of the IGU may be increased.
  • An increase in relative area of the IGU may further improve light inflow and view through the skylight. This also reduces the area of sash, and so the likelihood of thermal bridges through which heat energy can escape (or enter) from the interior of the building.
  • the adherence between the IGU and the supporting section may be the only point of contact between the IGU and the supporting section. Additionally, the adherence between the IGU and the supporting section may be the only point of contact between the IGU and the first sash side member.
  • the supporting section carries the IGU in said open position of the skylight window.
  • This may have the advantage of enabling the IGU to be carried solely by a supporting section attached to its exposed exterior major surface.
  • a knock-on effect of this may be that no supporting section or sash is required around the peripheral sides or exposed interior major surface of the IGU, allowing for a more compact skylight window with less sash.
  • a more compact skylight window may facilitate a better integration in a roof structure and/or an installation that is more flush with the exterior side of the roof structure, as well as a better view out of the window.
  • a better and/or more flush integration in a roof structure may have the effect of improving the insulation properties as more of the skylight may be embedded in the roof structure.
  • a further advantage may be that there is less or no material around the peripheral sides or along the exposed interior major surface of the IGU with different thermal expansion properties, that have to be taken into account when considering the insulation and/or weatherproofing or sealing properties of
  • carries may be understood as the supporting section carrying a substantial load exerted on it by the IGU.
  • a substantial load may be 10, 20, 30, 40, 50, 60, 70, 80, 90, 95, 99% or more of the total load exerted by the IGU.
  • the supporting section is adhered to said exposed exterior major surface of the IGU by means of adhesive.
  • the adhesive may be silicone based eg. a Silane-terminated polyurethane (SPUR) adhesive or a silyl modified-polymer (SMP) adhesive etc.
  • SPUR Silane-terminated polyurethane
  • SMP silyl modified-polymer
  • the supporting section may be adhered to the exposed exterior major surface by means of suction cups.
  • the suction cups may work by providing at least a partial vacuum.
  • the supporting section may be adhered to the IGU by means of mechanical attachment devices such as screws, fasteners or the like. The mechanical attachment devices may be inserted through one or more layers of glazing of the IGU.
  • the adhesive is provided by means of adhesive tape.
  • the substantially only attachment of the first sash side member to the IGU is an adherence provided by the supporting section being adhered to said exposed exterior major surface of the IGU.
  • the supporting section may be adhered to the exposed exterior major surface of the IGU through a bottom surface of the supporting section.
  • the supporting section may be a non-integral part attached to another part of the first sash side member.
  • the supporting section may constitute or comprise, or be part of a thermal break.
  • the supporting section comprises or constitutes a thermal break.
  • the thermal break may be made from a material of a lower thermal conductivity than other parts of the first sash side member. This may have the advantage of improving the insulation properties of the skylight as a lower thermal conductivity through the supporting section or sash member may be achieved. Thermal breaks may also be used for interconnecting the window frame and the sash.
  • the thermal break may made be substantially made from or comprise a polymer or foam.
  • the first sash side member includes a further supporting section provided as a safety device catching the IGU in case said adherence fails in said open position of the skylight window.
  • the safety device may be provided as a safety clip.
  • the safety device may be mechanically attached to the first sash side member.
  • the first sash side member comprises a first leg, said first leg extending only above the exposed exterior major surface of the IGU, where said first leg may be connected to a second leg.
  • the first sash side member comprises a first leg and the first sash side member may be in the form of a stepped profile.
  • the stepped profile may provide a labyrinth like structure between the sash and frame side member, resulting in a less direct path for air, precipitation or dirt to pass between the interior and exterior of the building.
  • the stepped profile also provides the possibility of placing sealing elements along the profile such that sealing is facilitated between two parallel surfaces i.e. a surface of the frame side member and a parallel sash side member.
  • insulating sealing members may conveniently be positioned between the first sash and frame side members at respective corners of the stepped configurations, e.g. as described in the above.
  • a second aspect of the invention concerns a method of manufacture of a skylight window according to the first aspect of the invention, the method comprising the steps of:
  • This provides a skylight with a sash attached to the exposed exterior major surface of the IGU with the advantages as described above for the first aspect of the invention.
  • the method may further comprise a step of holding said bottom surface of the supporting section in contact with the exposed exterior major surface of the IGU until the adhesive has cured.
  • a holding element for holding said bottom surface of the supporting section in contact with the exposed exterior major surface of the IGU until the adhesive has cured, may be provided.
  • This may be in the form of a different adhesive such as an adhesive tape, suction cups, clamps etc.
  • the holding element adhesive may be a fast curing adhesive which cures faster than the adhesive securing the supporting section to the exposed exterior major surface of the IGU.
  • the method may comprise the step of applying the holding element adhesive to said bottom surface of the supporting section or the exposed exterior major surface prior to the step of bringing said bottom surface into contact with the exposed exterior major surface of the IGU.
  • all four sash side members have the structure as described for the first sash side member and that the corresponding or associated four frame side members are also adapted accordingly.
  • a length dimension in relation to the first sash side member, may be defined as a dimension in which said longitudinal direction extends, a height dimension may be defined as a direction perpendicular to the length dimension and to major surfaces of the IGU, and a width dimension may be defined as a dimension perpendicular to the height and length dimensions.
  • the width and length dimensions are thus parallel to the major surfaces of the IGU.
  • the longitudinal direction extends in the length dimension
  • the width and height dimensions can be said to extend in transverse or lateral directions.
  • the length dimension may also be denoted longitudinal direction.
  • the width dimension may also be denoted width direction.
  • the height dimension may also be denoted height direction.
  • the term "interior” is used to indicate that something is intended to face the interior of the building in which the skylight window is installed, in an installed position of the skylight window.
  • the term “exterior” is used to indicate that something is intended to face in a direction opposite to the interior of the building in which the skylight window is installed, in an installed position of the skylight window.
  • the terms “inner” and “outer” are used to indicate that something is intended for facing towards or away, respectively, from the opening in the frame of an assembled skylight window.
  • insulation insulation, insulating, insulation properties and “insulating properties” are to be understood in the sense of thermal insulation and thermal insulation properties and thermally insulating and insulating properties. However, other insulation may also be provided such as for example acoustic insulation.
  • skylight windows for inclined roofs are typically built into the roof structure.
  • the frame and sash i.e. most of the frame and sash structures, are embedded in the roof so that much, most or all of an outer surface of the frame facing away from the opening in the frame is positioned within the roof structure.
  • the inventors of the present invention have realized that in inclined skylight windows installed in this way the insulation properties of the frame and sash are to a large extent not decisive for the total heat loss through the window.
  • skylight windows where the frame and sash are positioned higher than the level of the roof i.e.
  • the typically inferior insulation properties of the frame and sash structures compared to those of the IGU are to a much lesser degree alleviated by the insulation properties of the roof structure.
  • the IGU is typically the best insulated part of the window, i.e. having the lowest thermal conductivity or "U-factor", unit W/(m2K), especially compared to the thermal conductivity of the frame and sash.
  • U-factor unit W/(m2K)
  • the IGU has multiple layers of glass which define a volume comprising an inert gas or aerogels or vacuum.
  • the IGU may in a conventional manner comprise two, three or more layers of glazing, i.e. layers of glass, polycarbonate or the like or glass panels, positioned at a distance from each other to form one or more spacings or cavities between them. This spacing may be filled with an inert gas or may hold a vacuum to improve insulation.
  • One or more of the layers of glazing may have a low emissivity coating or coating stack.

  • Hinges may be linear displacement mechanisms or multi-link mechanisms.
  • the sash may be made movable in relation to the window frame by the sash being top-hung, i.e. being rotatable about an axis extending along one of the sash side members. This may be achieved using a rotary hinge positioned at this sash side member and connecting this sash side member with an associated, adjacent frame side member.
  • the sash may be parallel-displaceable so that all four sash side members shift upwardly or downwardly between the open and closed positions of the window in which case further or other hinges or the like connect the sash with the frame.

  • the exterior major surface may be substantially parallel with and/or may have substantially the same or the same shape and size as the interior major surface of the IGU. A distance between the two major surfaces defines a thickness of the IGU, which distance may be measured in the height dimension.
  • the IGU may have a rectangular shape and may have further second to fourth peripheral sides that each extends linearly along, potentially along substantially a total extent of, a corresponding respective sash member.
  • the peripheral sides may define a shape of the IGU.
  • the four frame side members may together form a substantially rectangular shape. Additionally or alternatively, the four sash side members may together form a substantially rectangular shape.

  • the weather shield may be provided as a unitary structure, which is detachably attached to the sash.
  • the weather shield may be attached detachably to the sash, providing for access to clean the IGU; this may also be of advantage during installation of the skylight window, e.g. when positioning or attaching the window portion or when attaching roofing felt to cover a potential gap between the frame and the roof structure.
  • the weather shield is mounted on the window portion to protect it from the elements and preventing rain and other downfall from entering into gaps or slots in the roof or the window portion.

This means that it is possible to substantially reduce the strength and/ or stiffness of the first and second legs of the first sash side member without compromising structural integrity of the first sash side member. As a consequence, the first and second legs may be made of smaller size, which again allows for positioning the IGU lower in the window structure as well as to use an IGU with a larger planar area, i.e. it extends further to the sides and so increase the relative area of IGU compared to the skylight window. This reduces the area of the sash and frame through which heat energy escapes from (or enters) the interior of the building.
  • the third leg may be provided in the form of a stiffening and/or strengthening leg, which substantially improves stiffness, strength, structural integrity and/or the like of the first sash side member. Accordingly, the third leg may affect stiffness, strength, moment of inertia and/or like structural properties of the first sash side member, including providing greater resistance to bending. Improved structural properties mean that the sash can hold a larger IGU or an IGU having a plurality of glazing layers.
  • the structural properties of the sash in this manner, it has been found that when holding IGUs of substantially the same size and weight as in the prior art, it is possible to decrease the size of other legs of the sash, specifically the first and second legs.
  • the IGU can be placed lower in the skylight window construction, and as such will improve the insulating properties of the skylight window.
  • the inventors have realized that inclusion of the third leg need not obstruct entry of light or the view through the IGU.
  • the inventors since it is possible to position the IGU lower in the window structure, entry of light and view through the IGU may, in fact, be improved.
  • the third leg may comprise the only or substantially the only supporting surface or supporting point of the first sash side member resting on the frame in the closed position of the skylight window.
  • a corresponding third leg may comprise the only or substantially the only supporting surface or supporting point of the respective sash side member resting on the frame in the closed position of the skylight window. This may provide an improved ability to position and center the skylight window during closing thereof.
  • Other contact points or contact surfaces between the sash and frame in the closed position of the skylight window, which contact surfaces are not carrying any substantial amount of the weight of the sash in the closed position of the skylight window, may include sealing members between associated sash and frame side members.
  • An insignificant amount of a weight of the sash in the closed position of the window can be defined as less than 20, 10, 5, 3, 2 or 1 percent of a total weight of the sash the sash imposed by the first sash side member on the first frame side member. It is preferable that the only contact points between one, two, three or four of the sash side members to the associated frame side member are established by the abutment element(s) and potential sealing members, potentially a hinge and/or a chain drive for moving the sash.

  • the first leg having a thickness less than 1 cm may have the advantage of allowing the IGU to extend closer to the frame side members as the thickness of material extending along the peripheral sides of the IGU is reduced.

Moreover, this will lead to a more lightweight structure that can potentially be easier to manufacture and lead to cost savings with regards to the material use. Furthermore, the small thickness of the first leg will lead to a better appearance for the window, having an aesthetic superiority compared to conventional thicker window sash. Eventually, that will also lead to improved daylight conditions, as the daylight inlet may be increased due to the increase of the glazing area that the IGU covers. The thinner leg of the first sash side member may also facilitate the placement of two skylight windows side by side, due to their slimmer structure.

This is turn means that the excellent insulating properties of the IGU can be exploited and potentially also that the light admitting area of the IGU, i.e.
  • the distance between a peripheral side of the IGU and an inner side of a frame side member extending substantially in parallel with said peripheral side of the IGU and facing towards the IGU is less than 20 mm, preferably less than 15 mm.
