Definitions

  • the present invention relates to a skylight window for being installed in an inclined roof of a building, the skylight window comprising: a window frame having four frame side members, said frame members defining an inner opening and each frame member, having an inner side facing said inner opening and an outer side facing in an opposite direction of the inner side and away from the inner opening, an interior side for, in an installed position, facing an interior of the building, and an exterior side for facing in an opposite direction of the interior side and away from the interior of the building; an Insulating Glazing Unit (IGU) having multiple layers of glazing, said IGU having an interior major surface facing in an interior direction for facing an interior of said building in the installed position of the skylight window, said IGU further having an exterior major surface facing in an exterior direction opposite the interior direction towards an exterior in said installed position of the skylight window; where a height direction is defined as a direction that is substantially parallel to an interior-exterior direction extending between the inner and exterior side of a frame member; and a weather shield comprising a weather shield pane positioned on an exterior side
  • 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.
  • 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 the flat-roof 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.
  • skylight windows on flat roofs and potentially cover the window portion with a dome-shaped weather shield.
  • a skylight window is disclosed in WO 2009/080026 A1 .
  • This window comprises a standard VELUX ® outwardly opening window, to the sash of which a dome-shaped weather shield is attached.
  • skylight windows of the prior art may be associated with relatively poor insulating properties of the finished roof structure with the skylight window. This may be attributed to the manner, in which flat-roof skylight windows are installed, resting on top of the roof structure of a building, which generally results in a relatively large proportion of the skylight window being exposed to the surrounding environment.
  • a further object of the invention is to provide a method for installing a skylight window, which leads to improved insulation properties of a roof structure with a skylight window installed therein.
  • a still further object is to provide improved inflow of light into a building.
  • At least the first mentioned object is achieved with a skylight window, wherein at least one mounting element attached to the outer side of a first frame side and comprising a roof mounting surface for mounting the skylight window to an exterior support surface of a load bearing structure of the inclined roof, wherein said roof mounting surface is substantially perpendicular to the height direction and extends away from the outer side of the first frame side member and the inner opening, and wherein the interior major surface of the IGU is located below the roof mounting surface of the mounting element when seen in the height direction.
  • the IGU By the interior major surface of the IGU being located below the roof mounting surface of the mounting element when seen in the height direction, i.e. further towards the interior of the building in the interior direction, the IGU will be located substantially in plane with the roof structure. This means that the excellent insulating properties of the IGU will be better utilized than when the IGU is located above the roof mounting surface of the mounting element and hence above the exterior side of the roof structure.
  • the at least one mounting element may for example be one or more mounting brackets attached to one or more frame side members or one or more curb flanges attached to or integrated in one or more frame side members.
  • the exterior support surface of a load bearing structure is here understood as the surface on which the window frame of the skylight rest in a mounted condition. It is not necessarily identical to the exterior side of the roof as such, as the load bearing structure will typically be covered with a roofing material after the installation of the skylight window.
  • the roofing could for example be a roofing felt, shingles, tiles or the like.
  • the support surface of the load bearing structure could for example be an exterior side of at least one batten.
  • IGU is an abbreviation of "Insulating Glazing Unit” and is a concept well-known to the skilled person.
  • the IGU may have multiple layers of glass or tempered glass which define a volume comprising an inert gas or aerogels or vacuum.
  • the IGU may in a conventional manner comprise one or, preferably two, three or more layers of glazing positioned at a distance from each other to form one or more sealed 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.
  • One or more of the layers of glazing may be laminated e.g. the interior layer of glazing.
  • One or more of the layers of glazing may be tempered.
  • the weather shield pane may be tempered.
  • the IGU may be see-through transparent to provide a view out.
  • the exposed interior major surface of the IGU may in that case be a lower major surface of a lowermost of the layers of glazing.
  • Sealing and/or supporting members may be provided at one or more of four peripheral sides of the IGU between the layers of glazing.
  • the sealing and/or supporting members may distance adjacent layers of glazing from each other and may together with lateral edges of the window glazing layers form respective side or lateral surfaces of the IGU. These side surfaces may be substantially plane and extend substantially in the height dimension as defined herein.
  • the exterior major surface of the IGU is located below the roof mounting surface of the mounting element when seen in the height direction, so that the entire IGU is located below the roof mounting surface. This will provide particularly good insulating properties.
  • 10% or more of the total height of the IGU is located below the roof mounting surface of the mounting element, said total height extending from the interior major surface of the IGU to the exterior major surface of the IGU in the height direction. This may be advantageous in order to make room for other parts of the skylight window and/or to achieve a desired distance between the IGU and the weather shield pane, which may for example allow for an improved inflow of light.
  • Other relative locations with for example 25%, 50%, or 75% of the total height of the IGU located below the roof mounting surface of the mounting element are also possible.
  • the weather shield pane is preferably a transparent cover member, preferably a dome of glass or a clear polymer.
  • the weather shield pane may be a transparent window pane that of glass or hardened glass.
  • a weather shield having an exterior shield surface, which is substantially parallel with at least one of the major surfaces of the IGU.
  • a space between the weather shield and the IGU is typically ventilated, whereas the IGU comprises a sealed gas-filled spacing pane layers.
  • the weather shield pane may also include two or more layers with a gas filled space between them.
  • the weather shield pane may comprise only one single layer of glazing.
  • the weather shield may be provided as a unitary structure, which is detachably attached to the 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 mounting 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 pane may be attached to the window frame so as to protect a window portion of the skylight window, the window portion comprising the frame and the IGU, and/or may form part of the IGU.
  • the weather shield may be provided without a sealed gas-filled spacing between the weather shield pane and the IGU.
  • the weather shield may comprise a weather shield pane that may be surrounded by a weather shield skirt that may extend on an outer side of all four sides of the frame, i.e. of the respective frame side members.
  • the skirt may be manufactured from or include metal.
  • the weather shield pane may curve upwardly in relation to the window portion or the IGU to allow for rain and snow to slide or flow off of the weather shield pane.
  • the exterior major surface of the IGU has a major surface perimeter and the weather shield has a weather shield perimeter, and the weather shield perimeter extends beyond the major surface perimeter along the entirety of the major surface perimeter. This allows the weather shield to cover the IGU entirely and protect it from dirt and precipitation.
  • the weather shield pane In order to allow rain water etc. to be drained off the skylight window and onto the roof surface it is presently preferred that, in the closed position of the skylight window, the weather shield pane is positioned above the roof mounting surface in the height direction. However, it may be desired to make the total skylight window protrude as little above the exterior side of the roof as possible.
  • an openable skylight window it may further comprises a window sash supporting the IGU, said window sash being movable in relation to the window frame between an open and a closed position of the skylight window.

  • the thermal break may be made from a material of a lower thermal conductivity than other parts of the first sash side member.
  • the thermal break may be a joint joining parts of the sash. 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 be substantially made from or comprise a polymer or foam.
  • the interior major surface of the IGU is located below the support surface of the loading bearing structure of the roof in the height direction, and the weather shield pane is positioned above the support surface of the load bearing structure of the roof in the height direction.

  • the first frame side members may comprise a core of a wooden or wood-based material encapsulated in a PUR shell, as this may provide a first frame side member which is rigid and strong, and which can support the skylight window.
  • the core provides rigidity and strength, while the shell protects the core from adverse conditions such as water, humidity and/or sunlight.
  • a skylight window for being installed in an inclined roof of a building, the skylight window comprising:
  • the supporting surface is covered with roofing such as roofing felt, shingles, tiles or the like after the installation of the skylight window.
  • the weather shield may be removed prior to arranging the window frame of the skylight window on the load bearing structure of the inclined roof. This will for example allow a mounting bracket to be secured to a frame side member or a previously attached mounting bracket to be unfolded or adjust to a desired installation depth or to a particular roof type. Also, a removal of the weather shield may allow the installation of a flashing to make the finished roof structure water tight. After installation/adjustment of such elements, the weather shield is re-attached. It will of course also be possible to provide the weather shield separately and to only connect it the to the rest of the skylight window when such installation/adjustment steps have been completed.

This allows for the IGU 5 to be positioned high, in the height direction, in the skylight window 1 and makes it possible to have the lining panel protrusion 10e above the bottom surface 10a, in the height direction, of the first frame side member.
  • the top end of the lining panel 50 is above the bottom surface 10a.
  • a sealing member 22 abuts to the IGU and hereby hides the first side member for a viewer viewing the skylight window, in an installed position, from the interior towards the exterior.
  • the sash 14 being in the space between the first frame side member 10, the IGU 5 and the weather shield 3.
  • the top pane of the IGU 5c has a larger perimeter than the other panes of the IGU 5 in the plane of the interior major surface 5b of the IGU.
  • Fig. 6 shows a perspective view of an embodiment of the skylight window 1 according to the present invention installed in a roof 2 (not shown), where a part of the window has been removed for illustration purpose.
  • the window frame 7 and the window sash 6 correspond to the ones shown in Fig. 8.
  • the weather shield pane 8 here has been removed for clarity.
  • Fig. 11 also shows a screening device 34, which is mounted in a spacing delimited in the width direction W by the first sash side member 14 and the remaining sash side members. It is to be understood that the remaining sash members are substantially identical to the first sash side member 14 so that the exterior sides of the sash side members together define an exterior side of the sash 6 which extends substantially in parallel to the exterior major surface 5g of the IGU 5.
  • the screening device 34 is here depicted as a roller curtain in which the screening body 36 is a covering cloth, which at least partially rolled up on a collection device 35 in the form of a collection roller in the first non-screening, end position, but which is here shown in a second, screening end position, where it is extended towards a second sash side member 6 for covering the IGU 5.
  • the screening device 34 might, however, also be another type of blind or a shutter.
  • a fixation member 39 is attached to the first sash side member 14 and extending towards the second sash side member. The fixation member 39 contributes to retaining a top casing of the screening device 34 by preventing it from moving upwards, away from the exterior major surface 5g of the IGU.
