Definitions

  • the present invention relates to a skylight window for being installed in or on 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.
  • Window sashes have typically comprised box structures consisting of hollow spacings as an attempt to provide structural support and thermal insulation through cavities.
  • a typical example of such structures is presented in US2010269426 .
  • Windows comprising such sashes have typically a quite rough appearance, while limiting the view. What is more, these windows are usually associated with high materials and processing costs in terms of manufacturing the window sash.
  • 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 as mentioned above.
  • the poor insulating properties 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 before reaching 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.
  • another objective of the invention would be to provide a slimmer window sash having lower manufacturing costs and a more lightweight structure.
  • a skylight window according to the introduction, characterized in that at least a portion of said first leg of the first sash side member is generally plate-shaped, consisting of one single section of substantially solid material having a said thickness less than 1 cm.
  • plate-shaped may be understood as the first sash side member being generally flat.
  • substantially solid material may be understood as no cavities and/or hollow spacings are comprised in the material structure.
  • substantially cavity may be understood as any cavity being created between two material layers exceeding e.g. 1mm.
  • said portion of the first leg does not include other sections, which surround or extend in parallel with said single section so that a core spacing is formed between them within said first leg as it is known from the extruded sash and frame profiles, made for example from aluminium or polymer, which are used in many traditional windows.
  • the portion of said first leg having a thickness less than 1 cm of the first leg may correspond to any estimable part that comprises the first leg.
  • thickness of said first leg refers to the extent that the first leg extends in the direction of the width dimension, being perpendicular to the height and length dimensions, as defined previously.
  • 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. This may have the effect of improving the insulation properties of the skylight as the relative area of the superior insulating IGU is increased compared to other parts of the skylight. 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.
  • the first leg of the sash may have a height to thickness ratio of at least 4:1. That means that the leg's height is substantially larger than the leg's width, which can also be perceived as a particularly thin oblong element.
  • the height to thickness ratio may also be 5:1, 6:1, 7:1 etc. If the first leg extends between the interior major surface of the IGU and the exterior major surface of the IGU, i.e. along the outer side of the IGU at the peripheral side, having a thin first leg means that the IGU can come closer to the frame. 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.
  • Reducing the thickness of the material extending along and/or on top of the peripheral sides of the IGU may also lead to significant cost savings with regards to the manufacturing of the window sash and the associated material costs.
  • the sash side members are connected to the exterior major surface of the IGU and extending away from the interior major surface of the IGU, i.e. not extending below the exterior major surface of the IGU in the mounted state. In this way the IGU will be positioned as deep as possible in relation to the roof structure, thereby potentially improving the insulating properties of the window.
  • the sash side member may further comprise a second leg and possibly further legs in order to allow a more complex structure.
  • the second and/or possible further legs may also be substantially plate-shaped.
  • the legs form a stepped profile, when the cross-section perpendicular to the longitudinal direction.
  • An upper surface of the second leg may be denoted a step surface.
  • a step profile may be achieved by making the sash side member with two, three or more legs where each leg is substantially perpendicular to an immediately preceding leg and/or an immediately following leg.
  • a stepped configuration of adjacent surfaces of the first sash and frame side members may thus be achieved by means of the stepped profile of the first sash side member as described and an associated stepped profile of the first frame side member according to the present embodiment.
  • This stepped configuration may provide a labyrinth like structure of a potential 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.
  • the sealing between the stepped profile of the sash and frame side member may further be aided by the load transfer of the load exerted by the IGU through the sash.
  • 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.
  • insulating and sealing properties of the skylight window may be further increased.
  • Such a step may also be used for supporting a screening device, such as a roller blind.
  • a second, third and/or fourth sash side member is/are substantially similar and/or identical in shape and/or form and/or size and/or structure to the first sash side member.
  • the skylight window may comprise one or more thermal breaks being located in the sash side member.
  • Thermal breaks are manufactured 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 window as a lower thermal conductivity through the supporting section or sash member may be achieved.
  • the thermal break may be substantially made from or comprise a polymer or foam.
  • the thermal breaks may be located on the sash side member, so that possible thermal bridges are avoided.
  • a thermal break is provided at an exterior edge of the first leg located above the exterior major surface of the IGU when seen in the height direction, i.e. on the exterior side of the IGU.
  • the legs are attachable/detachable to/from each other. This would for example allow the first leg to be replaced with one of another height, so that the window sash has an adjustable height that could be used for different installation depth.
  • the window sash will be able to adjust its height also based on the number of layers of glazing included in the IGU. For example, an IGU comprising two layers of glazing may require a shorter sash height than an IGU with three layers of glazing.
  • the sash may also be adjusted for different frame sizes.
  • the sash side member may comprise one or more recesses that may be adapted for securing one or more sealing elements (e.g. gaskets), said recesses may lead to a larger thickness of the sash side member in some limited areas, but the thickness should preferably not exceed 3 cm.
  • the recesses may be in the form of a groove or an indentation on any of the legs of the first sash side member.
  • the recesses may also secure centering blocks that may be attached to the sash in order to carry load so that the sealing elements are not too heavily deformed and thus, damaged.
  • the recesses may also be formed between projections, such as feathers extending in the longitudinal direction, and may include barbs or like elements designed to prevent the sealing elements from coming loose unintentionally.
  • the first leg may comprise or substantially consists of metal, such as steel or aluminium and/or polymer.
  • the metal structure may make the sash extremely resistant to high temperatures, which may arise due to high solar gains.
  • the first leg may comprise or substantially consist of a polymer, which may be fibre reinforced, one example being a thermoset plastic polymer material comprising glass fibers.
  • a thermal break may be comprised on the sash side member along with a metal discontinuity, having a different thermal conductivity, which will eventually lead to lower thermal losses through the sash.
  • the frame side members may have a bottom surface facing in a direction away from the interior major surface of the IGU, which bottom surface comprises a recess for receiving an upper part of a reveal panel or lining panel in said installed position of the skylight window, said recess comprising a first surface for abutting an inwardly facing interior surface of said reveal panel or lining panel when received in said recess.
  • the sash side members may be separate members or may be formed as one continuous member.
  • 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 may have multiple layers of 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, 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.
  • 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 is in that case 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.
  • Hinges may be linear displacement mechanisms or multi-link mechanisms.
  • the skylight window may be hinged to open in the exterior direction i.e. away from the interior of the building.
  • the sash may be made movable in relation to the window frame by the sash being outwardly hung, i.e. being rotatable about an axis extending along one of the sash side members. Generally by outwardly hung it is to be understood that the sash moves outwards from the frame during opening. This is contrary to pivot hung skylights which move both outwards and inwards during opening and employ a different design.
  • the sash being outwardly hung may be achieved by 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 skylight window may be openable by a combination of a rotary movement and a shifting movement or other movement paths of the sash in relation to the frame.
  • the exposed interior major surface of the IGU may be a lower surface of the IGU and/or may face in a downwards direction towards an interior of the building in an installed position of the skylight window.
  • the exposed interior major surface faces in a direction away from the weather shield.
  • the IGU comprises an exposed exterior major surface positioned oppositely from the exposed interior major surface and facing towards the outside, in an installed position of the skylight window.
  • 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. A rectangular shape of the four sash side members may be smaller than a rectangular shape of the four frame sash side members, which may allow the sash to be embedded within the frame.
  • 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 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.
  • 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 weather shield pane may be a transparent window pane that may be of glass or hardened glass.
  • the weather shield pane may comprise only one single layer of glazing.
  • the weather shield may be understood as a transparent cover member, preferably a dome of glass or a clear polymer.
  • the first sash and/or frame side member may extend substantially along an entire length of said first peripheral side or side surface of the IGU.
  • the first leg may have a height in the height dimension of at least 1.5, 1.8, 2 or 2.2 times a height or thickness of the IGU, where the height of the IGU as mentioned may be defined as a distance between its exposed exterior major surface and its exposed interior major surface. Additionally or alternatively, the first leg may have an inner side surface facing a side surface of the first peripheral side of the IGU, this inner side surface extending 1.3, 1.5, 1.8 or 2 times the height or thickness of the IGU.
  • the first sash side member may in general in all embodiments have a substantially uniform cross section along a length of the first sash side member in said longitudinal direction.
  • the first frame side member may have a substantially uniform cross section along a length of the first frame side member in said longitudinal direction.
  • One or more of the remaining sash and frame side members may similarly have substantially uniform cross sections in the same manner.

  • one or more or all individual ones of the legs mentioned herein of the sash and frame members may be provided separately from each other, each leg potentially being attached to adjacent legs.
  • these two legs may be provided integrally or in one piece with each other.
  • said first sash side member further has a third leg projecting from an inner end of said second leg in a direction away from said interior major surface of the IGU to provide a lower supporting surface which in the closed position of the window rests on a corresponding upper resting surface of the first frame side member.
  • the direction away from said interior major surface of the IGU, in which direction the third leg projects, may extend substantially in the height dimension and/or may extend downwards, i.e. towards an interior the building in an installed position of the skylight window.
  • Said inner end of the second leg may be positioned opposite from an outer end of the second leg, said outer end preferably being connected to the first leg at a position from which the second leg projects.
  • Said inner end may be denoted a proximal end and said outer end a distal end with relation to the first leg.
  • the third leg of the first sash side member may provide additional support to the IGU, which is a typically relatively heavy component of the window. 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 abutment element (s) may be of or comprise an elastic material and/or a plastic material and/or a sealing material. The abutment element may be deformed in the closed position of the skylight window.

  • the first, second and third grooves 28, 29, 80 are adapted for receiving the fixation member 30, which can be attached to or snap-locked to either one of the two grooves 28, 29, 80 abutting the exterior major surface of the IGU 5 so as to hold the IGU 5 along said first peripheral side 5a thereof, especially in the upward direction.
  • the fixation member 30 is positioned in the groove 80 in the shown embodiment.
  • the fixation member 30 is manufactured of a plastic and sealing material and comprises a projection adapted to be in abutment with the upper or exterior major surface 5g of the IGU 5 such as to hold this in place against the upper resting surface 16a of the second leg 16.
  • the fixation member 30 extends substantially along an entire length (in the longitudinal direction L) of the first peripheral side 5a of the IGU 5. Similar fixation members are attached to similar grooves of the one, two or three of the other sash side members at the other three peripheral sides of the IGU 5.
  • a chain drive or the like may be provided connecting the sash 6 and frame 7 for assisting in opening and closing the skylight window 1.
  • the sash side member 14 has a fourth leg 31 projecting from an upper end of the first leg 15 in the outward direction away from the IGU 5 in the width dimension.
  • the fourth leg 31 is in the closed position of the window 1 positioned above the primary leg 25 of the frame side member 10 as shown in Fig. 3 .
  • the fourth leg 31 has a flat shape so that an upper surface thereof forms a further upper step surface similar to and potentially extending substantially in parallel with the upper resting surface 16a of the second leg 16.
  • the fourth leg 31 has an oblong shape in the width dimension and extends more than 4 times longer in the width dimension than in the height dimension.
  • the extent in the length dimension of the fourth leg 31 is substantially equal to about equal to or somewhat longer than the extent of the first peripheral side 5a of the window pane 5 in the length dimension.
  • an angle between the first 15 and fourth 31 leg is substantially 90 degrees.
  • the fourth leg 31 is formed integrally with the first leg 15.
  • the fourth and second legs 31, 16 extend or project substantially in parallel.
  • the fourth leg 31 is substantually shaped as a rectangle, a surface 31 b of the fourth leg 31 extending substantially along an upper surface 25c of the primary leg 25 being parallel to the upper surface 25c.
  • the fourth leg has an overall or total height in the height dimension less than the thickness of the IGU 5.
  • the skirt 9 of the weather shield 3 is attached to each of the fourth legs of the four sash side members as seen in Fig. 1 .
  • the sealing element 78 is made of an elastic, plastic and sealing material.
  • Similar sealing elements are provided in a similar manner on the remaining frame side members.
  • the sealing elements form the only or substantially the only resting point or resting surface of the sash 6 (including the IGU 5 and the weather shield 3) on the frame 7 in the closed position of the skylight window 1.
  • roofing felt may in a conventional manner be positioned to seal between outer surfaces of the frame 7 and of the roof 2. These outer surfaces of the frame 7 are here formed by a curb flange of the frame 7.
  • a curb flange 40 is shown, which curb flange 40 has an overall triangular shape and forms part of the frame side member 10. Similar curb flanges are here provided at the remaining frame side members.
  • Fig. 4 shows a cross-sectional view of the skylight window 1.
  • the weather shield 3 is dome-shaped.
  • the supporting section 72 of the first sash side member may extend further than shown in Fig. 4 . It may also comprise a thermal break 75.
  • the thermal break 75 may be made from a material of a lower thermal conductivity than other parts of the first sash side member 12 and is used to reduce any potential thermal bridges from the sash.
  • the supporting section 72 may also comprise a material discontinuity to reduce the heat transfer at this point, hence the thermal break may be used to insulate the specific part of the sash side member.
  • the supporting section may also comprise a fixation element 76, which fixation element 76 acts as support between the IGU and the first sash side member and/or may be made of a material that has insulating properties.
  • the first leg has a thickness in a width direction extending perpendicularly to said length and height directions which is denoted with T.
  • the first leg 15 of the first sash side member is generally plate-shaped, consists of one single section of substantially solid material and at least a portion of the first leg has a said thickness less than 1 cm.
  • the legs of the first sash side member 14 may be attachable or detachable from each other.
  • the first leg 15 may comprise metal.
  • the sash is made from a thermoset plastic polymer material comprising fibers, but could also comprise metal such as aluminium. This provides a siginficantly thinner sash which allows the IGU to be placed lower in the window structure and extend closer to the frame side member.
  • the first leg having a thickness of less than 1 cm allows the distance between the peripheral side 5f of the IGU and the inner side surface 25b of the first frame side member 10 facing towards the IGU, to be less than 20 mm.
  • This provides a significantly thinner sash which is particulaly advantagous when the sash extends along the exposed interior major surface of the IGU 5b and/or along a peripheral side of the IGU 5 as the reduction in material thickness allows the IGU to be positioned lower in the window structure and extend closer to the frame side member as seen in Figs 2-4 .
  • Positioning the IGU lower and making it extend further to the sides contrigutes to the overall insulating properties of the skylight window as IGUs generally have better insulating properties than the material used for the sash and frame.
  • the IGU 5 is supported by a first sash side member 14 and the skylight has a weather shield 3, which is substantially flat here, with a weather shield skirt 9.
  • the first leg 25 of the first frame side member 10 extends in the height direction and the second leg 26 of the first frame side member extends in the width direction.
  • the second leg 26 extends from the first leg 25 in the width direction toward a frame opening 201.
  • part of the bottom surface 10a is positioned on the roof 2, whereby the window frame is supported by the roof 2, and part of the bottom surface 10a extends above the opening in the roof.
  • the first frame side member 10 and the first sash side member 14 extend in a length or longitudinal direction L, along the side surface 5f of the interior pane in the closed position of the IGU 5.
  • the first sash side member 14 has a supporting section 72, the supporting section 72 being positioned below the interior major surface 5b.
  • the supporting section 72 carries at least part of the weight of the IGU 5.
  • the first sash side member 14 further has the first leg 15 connected to the supporting section 72.
  • the first leg 15 extends in the longitudinal direction L and in the height direc-tion H.
  • the first leg 15 is generally plate-shaped and consists of only one sin-gle section of substantially solid material having a thickness in the width direc-tion of less than 1 cm.
  • the first frame side member 10 in Fig. 5 is substantially L-shaped, the first leg 25 extending in the height direction H, and the second leg 26 extending from a lower portion of the first leg 26 in the width direction W toward the IGU.
  • the first frame side member further has a supporting section 112, the supporting section 112 is connected to the second leg 26 and is positioned below the IGU 5 in the height direction H. In the closed position shown in Fig. 5 , the supporting section 112 carries a structural load of the IGU 5 and the first sash side member 14.
  • the supporting section 112 is connected to the second leg 26, and in an installed position of the skylight window 1 on the roof 2, the structural load from the IGU 5 and the first sash side member 14, is transferred from the supporting section 112 to the second leg 26 and further to the roof 2.
  • a sealing element 22 is provided between the supporting section 112 and the interior major surface 5b.
  • the outer side 110a of the first leg 25 faces away from the frame opening 201 and the bottom surface 10a of the second leg 26 faces in the interior of the building, in the interior direction D.
  • the major outer surface 110b of the outer side 110a is both perpendicular and adjacent to the bottom surface 10a of the second leg 26.
  • the first frame side member 10 has a pre-formed hole 45.
  • the pre-formed hole 45 extends from the major outer surface 110b toward the bottom surface 10a in a direction inclined in relation to frame plane.
  • the pre-formed hole 45 is a through-hole.
  • the pre-formed hole 45 forms an angle ⁇ with the frame plane. In this embodiment the angle ⁇ is approximately 70 degrees.
  • Fig. 6 shows a perspective view from above 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. 5 .
  • the weather shield pane 8 here has been removed for clarity.
  • Fig. 6 also shows a screening device 34, which is mounted in a spacing delimited in the width direction W by the first 14 and second sash side members.
  • the second sash member is 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 IGU 5 in this embodiment comprises three layers of glazing 5c, 5e, 5d in the form of glass panels, positioned at a distance from each other by sealing members 23, 24 located at peripheral sides of the IGU between the layers of glazing to form two spacings 25. These spacings 25 are filled with inert gas to improve insulation.
  • the top layer of glazing 5c in this embodiment is larger than the other layers of glazing 5e, 5d of the IGU 5 and extends farther in the width direction, the layers of glazing however, may be of equal size in other embodiments.
  • the first frame side member 10 further comprises a lining panel protrusion 10e located lower than the exposed interior major surface 5b of the IGU 5 in the height direction.
  • the lining panel protrusion 10e protrudes away from the IGU 5 and has a first surface 10c for abutting a surface of the reveal panel or lining panel 50 so as to position a reveal panel or lining panel 50 as shown in Fig. 7 .
