Description

Technical Field

[0001] The present invention relates to a roof window, which includes a frame, a window frame and a pane. In the roof window, the frame includes a set of frame members, the set of frame members including a top frame member, two side frame members and a bottom frame member, and the window frame includes a set of window frame members, the set of window frame members including a top window frame member, two side window frame members and a bottom window frame member. Each frame and window frame member defines a longitudinal direction, and the pane includes a plurality of edge portions and an outer pane surface, the outer pane surface defining the plane of the roof window in the assembled state of the roof window. The present invention also relates to a method of manufacturing such a roof window. Background Art

[0002] There are various types of roof windows installed on inclined roof surfaces. When selecting a type of roof window for a specific installation location in a building, parameters such as operability, thermal performance, weather resistance and proper decoration of the building interior are usually given substantial weight; however, it is generally desirable and in some areas actually necessary to consider the external appearance. This is particularly applicable to the installation of roof windows in protected areas, where building regulations may require the roof windows to meet standards or local requirements. Therefore, certain requirements apply depending on whether the installation involves newly installed roof windows or replacing existing windows or skylights as part of a renovation or refurbishment project.

[0003] Past windows or skylights were typically made of cast iron and individual glass pane elements, separated by one or more cast iron glazing bars, and the thermal efficiency of these roof windows or skylights left room for improvement. To meet the energy consumption performance required by modern building regulations, energy-saving roof windows are usually provided with insulated panes while starting to imitate the style of traditional skylights.

[0004] In many installation cases, it is also required that energy-saving roof windows can be installed with a "low profile", that is, the height of the part of the roof window protruding above the surrounding roof is as small as possible. This is particularly evident in buildings with a generally flat roof material such as slate or shingles. To meet this requirement, most major roof window manufacturers allow installation in at least two layers, thus adapting to the height and installation conditions of various roof profiles.

[0005] With the increasing awareness of environmental issues and the desire to reduce or even eliminate the climate footprint of products, there is also a need to provide more environmentally friendly products in terms of manufacturing, supply, installation and use.

[0006] Considering all of the above requirements, improving roof windows for protection purposes is an ongoing task. Summary of the Invention

[0007] In this context, the object of the present invention is to provide a roof window which is not only particularly easy to manufacture and assemble, but which also provides sufficient weathertightness in use.

[0008] In a first aspect, this object and other objects are achieved by a roof window of the kind mentioned in the introduction, which roof window is furthermore characterized in that each window frame member comprises a profile element, an inner element and an intermediate element, and that in the assembled state of the window frame the intermediate element forms a connection between the profile element and the inner element of each window frame member, the profile elements of the window frame members being positioned along the respective outer edge portions of the pane in the assembled state of the window frame, and the profile elements of the top window frame member and the two side window frame members being formed as a set of longitudinal profiles having substantially uniform cross-sections.

[0009] By this design, the object of facilitating manufacture and assembly is achieved, since the longitudinal profiles forming at least the top window frame member and the side window frame members can be manufactured and assembled in a first step of the manufacturing process and are subsequently connected to the intermediate element and the inner element. At the same time, the profile elements of the window frame members can form part of the weathertight arrangement of the roof window in use, since they are all present along the outer edge portions of the pane.

[0010] In one embodiment, each profile element comprises a head portion and an adjoining outer portion, wherein in the assembled state of the roof window the head portion is substantially parallel to the plane of the roof window and wherein the adjoining outer portion is substantially perpendicular to the head portion. These measures provide a harmonious appearance and at the same time contribute to the weathertightness of the roof window.

[0011] In another embodiment, the pane comprises an outer sheet and at least one inner sheet, and wherein the outer sheet comprises an extension which extends beyond the bottom edge portion of the at least one inner sheet to the bottom edge portion of the outer sheet, the pane having common side edge portions and a common top edge portion. The provision of a so-called stepped pane not only improves the visual performance of the roof window, but also promotes the drainage of rainwater and other precipitation from the pane to the roof below the roof window, as seen along the slope of the roof. The bottom frame member remains protected under the extension of the outer sheet of the pane.

[0012] Preferably, the head portion of the profile element of each of the top window frame member and the two side window frame members is located on the outer side of the outer pane surface, preferably on the outer sides of the side edge portion and the top edge portion of the pane. In this way, rainwater and other precipitation falling on the pane will remain in the basin thus formed and will be guided downwards in the direction of the slope of the roof. Additionally, these features accentuate the appearance of the roof window so that it resembles a window of a traditional style.

[0013] At the bottom of the roof window, the roof window is less affected by weathering compared to the sides, especially the top. Preferably, the head portion of the profile element of the bottom window frame member is located on the inner side of the extension of the outer sheet of the pane. This makes it possible to fully utilize the advantages of the stepped pane.

[0014] In an embodiment that particularly contributes to the structural integrity of the roof window and further improves the weatherproof performance, the lengths of the profile elements of the two side window frame members are substantially equal to or slightly exceed the distance between the top edge portion of the pane and the bottom edge portion of the outer sheet of the pane, such that an overlap is provided between the profile elements of the two side window frame members and the profile element of the bottom window frame member.

[0015] In another embodiment, the inner elements of the window frame members form a coherent inner element window frame structure that supports the inner edge portions of the pane in the assembled state of the window frame. The inner elements of the window frame members preferably have substantially the same cross-section. The flexibility in the configuration of the inner elements allows for customization of the inner members according to, for example, various interior design lines.

[0016] In a currently preferred embodiment, in the assembled state of the window frame, a miter joint is formed between the profile element of the top window frame member and the corresponding profile elements of the side window frame members by a longitudinal profile. The miter joint provides a particularly cost-effective manufacturing and assembly process because the profile elements can be formed from a single coherent profile that is cut to form parts intended to constitute one side, the top, and the other side of the assembled window frame.

[0017] To improve the tightness at the corners of the window frame members of the roof window according to this preferred embodiment, a corner key can be provided at each miter joint. The corner key is preferably supplemented by applying a sealant, and the corner key can have a generally L-shaped configuration having two perpendicular legs separated by a channel. The channel is preferably provided with a set of main openings. More preferably, each leg abuts a hanging skirt on a first side. The hanging skirt is preferably provided with one or more secondary openings. This configuration is particularly advantageous for the proper distribution of a suitable sealant, thus ensuring that the area around the joining edges of the miter joint is completely covered by the sealant.

[0018] Advantageously, each leg abuts an inclined portion on a second side, and the channel advantageously ends in a tongue. The channel optionally abuts an inclined channel portion. These measures have proven to further improve the sealing performance.

[0019] In another embodiment, each longitudinal profile of the profile elements forming the top window frame member and the two side window frame members includes an inner portion adjacent to the head portion, and the inner portion is configured to overlap with the pane in the assembled state of the window frame. With this configuration, the drainage performance at the pane is further improved.

[0020] In a further refinement of this embodiment, the head portion of each profile element is configured to protrude outward relative to the outer pane surface in the assembled state of the window frame, and in the assembled state of the window frame, the inner portion preferably extends inward and toward the outer pane surface obliquely from the head portion relative to the head portion. In addition to improving the weather resistance by ensuring proper drainage of precipitation from the pane to the roof, this design also gives the roof window an appearance similar to that of a traditional-style window.

[0021] In a second aspect, a method of manufacturing such a roof window is provided.

[0022] Other proposed preferred embodiments and other advantages will be apparent from the following detailed description and the accompanying drawings.

[0023] The features described in connection with one of these aspects can also be incorporated into another aspect, and the advantages of the feature apply to all aspects into which it is incorporated. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] In the following detailed description, preferred embodiments of the present invention will be described. However, it should be understood that the features of different embodiments may be exchanged between the embodiments and combined in different ways, unless otherwise specifically indicated. It should also be noted that, for clarity, the dimensions of some components illustrated in the drawings may be different from the corresponding dimensions in the actual implementation.

[0064] Note that terms such as "upper", "lower", "left side", "right side", "outer", "inner", "outside", "inside" are relative and relate to the perspective under discussion. Generally speaking, when referring to the outer part, this relates to the side of the roof window that faces the outside of the building or the outdoors in the installed state. Conversely, the inner part relates to the side that faces the inside of the building, i.e., the room below that usually includes any light well. Terms such as "outward" and "inward" are directions that are generally perpendicular to the inside-outside direction, with the center of the roof window as its reference point.

[0065] General description of the roof window- Figure 1 and Figure 2

[0066] First, referring to Figure 1 and Figure 2 , a roof window 1 is shown. The roof window 1 is intended to be installed on an inclined roof surface (not shown).

[0067] The roof window 1 includes a frame 2, a window frame 3, and a pane 4. The frame 2 includes a set of frame members, and the set of frame members includes a top frame member 21, two side frame members 22, 23, and a bottom frame member 24. Correspondingly, the window frame 3 includes a set of window frame members, and the set of window frame members includes a top window frame member 31, two side window frame members 32, 33, and a bottom window frame member 34. Although the frame 2 and the window frame 3 are described as rectangular structures, some principles of the proposed concept can also be applied to other geometries.

[0068] As will be described in further detail below, the pane 4 includes a plurality of edge portions that are typically associated with the members of the window frame 3. When in the closed position, the outer pane surface 4e defines the plane of the roof window 1 in the assembled state of the roof window 1. The assembly condition of the roof window 1 is achieved when the main components of the frame 2 and the window frame 3 have been assembled and the frame 2 and the window frame 3 are connected to each other, for example, in the installation position when the roof window 1 is ready. Correspondingly, the assembly condition of the window frame 3 is achieved once the main components of the window frame 3 have been assembled, and the assembly condition of the frame 2 is achieved when the main components of the frame 2 are assembled.

[0069] The inner pane surface 4i faces inward, typically the room in the building below the roof surface where the roof window 1 is installed. The outer surface 4e of the pane is fitted with a glass spacer 45, and the inner pane surface 4i is fitted with a glass spacer cover plate 46. Although not practical, there could also be a two-part pane, where the two panes are divided into two equal parts by a through glass spacer. In a wide roof window, there could also be more than one glass spacer, for example, two glass spacers that divide the surface of the pane visible from the outside into three parts.

[0070] In the illustrated embodiment, the window frame 3 is capable of being opened relative to the frame 2 to obtain one or more open positions. In such an open position, the window frame 3 and the pane 4 are moved out of the plane of the roof window 1. As will be described below, the window frame 3 is shown as top-hung, i.e., during normal use, the window frame 3 rotates about a generally horizontal hinge axis at or near the top frame member 21 and the top window frame member 31. However, it is contemplated that some principles of the proposed concept for the roof window could be applied to different types of windows with other opening methods or provided as fixed skylights.

[0071] Figure 1 and Figure 2 Other details shown in and include an operating assembly 5, shown here as a manual winder or screw jack. Other operating assemblies could also be present.

[0072] Also shown is a typical mounting bracket 6 forming part of a plurality of mounting brackets that form a load transfer connection between the roof window 1 and the surrounding roof structure (not shown). Such a roof structure may include rafters and battens, plywood or other construction materials.

[0073] Finally, a thermal insulation frame 7 is shown. Thermal insulation through the thermal insulation frame is optional and may be provided only along some of the frame members or, as shown, around all four frame members 21, 22, 23, 24.

[0074] In the following description of the various embodiments, elements having the same or similar functions always have the same reference numerals. Appropriate variations and modifications will be apparent to those skilled in the art.

[0075] Mounting bracket and roof window with a set of mounting brackets - Figures 3 to 4

[0076] Generally, a roof window, such as Figure 1 and Figure 2 the roof window 1 shown in is equipped with a set of mounting brackets 6. As indicated, two mounting brackets 6 are fastened to each of the side frame members 22, 23. Below, a single mounting bracket 6 associated with one side frame member 22 will be described. The set of mounting brackets 6 will generally be the same, although variations are also possible.

[0077] The mounting bracket 6 includes a first bracket leg 61 for fastening to the roof structure and a second bracket leg 62 for fastening to the frame 2 of the roof window 1. For this purpose, the second bracket leg 62 includes engagement means that interact with corresponding receiving structures on the outer side of the side frame member 22 of the frame 2 of the roof window 1. This ensures that the mounting bracket 6 is correctly positioned on the side frame member 22 and facilitates the installation process. The positioning of the mounting bracket 6 can be indicated in the longitudinal and height directions of the side frame member 22, for example by appropriate markings and / or holes. The first bracket leg 61 of the mounting bracket 6 is connected to the second bracket leg 62 via a bend 614.

[0078] In the illustrated embodiment, the second bracket leg 62 is provided with a first engagement means 624 in a first part 621 of the second bracket leg 62 and a second engagement means 629 in a second part 626 of the second bracket leg 62.

[0079] Of these two engagement means 624, 629, the second engagement means 629 is configured to assume a non-active position and an active position, with the active position shown.

[0080] The first engaging device 624 is configured to be received in one receiving structure on the outer side of the frame member 22 in the mounted state of the mounting bracket 6 on the frame 2 of the roof window 1, and the second engaging device 629 is configured to be received only in its active position in another receiving structure on the outer side of the frame member 22 in the mounted state of the mounting bracket 6 on the frame 2 of the roof window 1. This is most clearly shown in Figure 4 wherein the first engaging device 624 is received in the first outer groove 27 and the second engaging device 629 is received in the second outer groove 27b. At least the side frame members 22, 23 each include a plurality of receiving structures at the outer side of the respective side frame member, such that at least one of the receiving structures interacts with the mounting bracket 6 in the mounted state of the roof window 1. Both the first outer groove 27 and the second outer groove 27b extend in the longitudinal direction of the side frame member 22 spaced from each other in the height direction, and the first outer groove 27 is located outside the second outer groove 27b as seen in the height direction.

[0081] Bring the second part 626 and the second engaging device 629 from the position in the opening 620 in the second bracket leg 62 to the position where the second part 626 is substantially positioned in the extension of the first part 621. The second part 626 and the second engaging device 629 are connected to the first part 621 via a hinge connection 625, such that the second part 626 is configured to be brought from the inactive position to the active position by rotating the second part 626.

[0082] In the illustrated embodiment, each of the first engaging device and the second engaging device includes flanges 624, 629 protruding at a substantially right angle from the respective first part 621 and second part 626. Alternative configurations, such as discrete spikes, are also conceivable.

[0083] Hinge assembly and coupling unit - Figures 6 to 7 and Figure 22 and Figure 23

[0084] First, referring to Figure 6 and Figure 7 , which show that the roof window 1 further includes a hinge assembly 9.

[0085] The hinge assembly 9 is configured to allow the window frame 3 to be cantilevered in a first operating state corresponding to normal use. That is, during normal use, the window frame 3 rotates about a substantially horizontal first hinge axis α at or near the top frame member 21 and the top window frame member 31 between a closed position and an open position.

[0086] Now also referring to Figure 22 and Figure 23As can be seen, the hinge assembly 9 includes a hinge unit 91 which has a frame hinge portion 92 connected at least to or capable of being connected to the top frame member 21, a window frame hinge portion 93 connected at least to the top window frame member 31, and a hinge pin 94 connecting the frame hinge portion 92 and the window frame hinge portion 93.

[0087] The term "connected to" means that the component in question is in a condition, state or position where the component in question is actually connected to a certain part, while "capable of being connected to" is intended to include conditions, states and positions where the component in question can be connected to the relevant part but is not necessarily connected to that part. In Figure 22 and Figure 23 the description of, the frame hinge portion 92 including any sub-components will be described as being connected to a part of the frame 2.

[0088] Hereinafter, the coupling unit 95 of the hinge assembly 9 will be described in considerable detail. The details of the hinge assembly 9 are described in more detail in a co-pending patent application of the applicant filed on the same day as the present application. [[ID=ll]]

[0089] The coupling unit 95 is configured to allow at least the frame hinge portion 92 of the hinge unit 91 to be selectively coupled to the top frame member 21 and optionally to one of the side frame members 22, 23. Hereinafter, the coupling unit 95 will be described as including both a top frame coupling plate 96 and a side frame coupling plate 97. Alternative configurations are conceivable.

[0090] The top frame coupling plate 96 includes a base portion 961 connected to the inner side portion of the top frame member 21. The top frame coupling plate 96 is connected to the top frame member 21 by means of a plurality of fastening means including at least one bolt 961c on the base portion 961 and two bolt elements also serving as engagement pins 962, 963. In this case, each engagement pin 962, 963 cooperates with an insert nut 982, 983 on the outer side portion of the top frame member 21. To accommodate the top frame coupling plate 96, the top frame member 21 includes a hinge assembly receiving serrated edge 29a and a set of openings 29c, 29e, where the opening 29e is a through-opening or through-hole.

[0091] The side frame coupling plate 97 includes a base portion 971 and is connected to the inner side portion of the side frame member 22 by means of a plurality of fastening means including at least one bolt 971e on the base portion 971 and at least one opening (not shown in detail) for a fastening means such as a screw 981. To accommodate the side frame coupling plate 97, the side frame member 22 includes a hinge assembly receiving serrated edge 29b and a set of openings 29d, 29f.

[0092] Operating component- Figure 8 and Figure 10

[0093] During normal use, i.e. when the roof window 1 has been installed and the user wishes to place the window frame 3 in a ventilation position, opening, closing and stopping can be achieved with the assistance of an operating assembly, such as the manual winder or screw jack forming the operating assembly 5 as shown.

[0094] First referring to Figure 8 , the operating assembly 5 includes a window frame fitting 55, a spindle portion 52 having a spindle 521, and a handle 522. The spindle 521 is connected to a socket fitting 51 via a nut portion 53. In the installed state of the operating assembly, the window frame fitting 55 is connected to the bottom window frame member 34 and the socket fitting 51 is connected to the bottom frame member 24, such that when the spindle portion 52 rotates relative to the nut portion 53, the bottom window frame member 34 moves relative to the bottom frame member 24.

[0095] In the illustrated embodiment, the roof window 1 can be provided in a supply state suitable for packaging and shipping, with the window frame fitting 55 connected to the bottom window frame member 34 of the roof window 1, while the spindle portion 52, the nut portion 53 and the socket fitting 51 are provided separately from the roof window 1.

[0096] The nut portion 53 includes a nut ring 531 which is connected here to a set of flanges 512 protruding from a base plate 511 of the socket fitting 51 by means of a set of bolts 532. A hole 513 is provided in the base plate 511 for mounting the socket portion 51 to the bottom frame member 24.

[0097] The operating assembly 5 further includes a split 56 associated with the window frame fitting 55 which is displaceable between an active position in which it engages with a set of openings 553 in a set of flanges 552 protruding from a base plate 551 of the window frame fitting 55 and an inactive position in which a receiving gap is shown between the flanges 552 of the window frame fitting 55.

[0098] The spindle portion 52 includes an end portion 54 configured to cooperate with the window frame fitting 55 in the installed state.

[0099] Window frame and frame structure- Figures 5 to 16

[0100] As Figure 8 and Figure 9 shown in the cross-sectional view of the bottom portion of the roof window 1 in Figure 4 and Figure 5, which respectively show the side part and the top part of the roof window 1. The window pane 4 has a common side edge part 4b and a common top edge part 4c, which are also suitable for the opposite, not shown side. The spacer 47 is arranged between the outermost inner sheet 42 and the outer sheet 41 along all the edge parts.

[0101] What all the window frame members 31, 32, 33, 34 of the window frame 3 according to the present invention have in common is that each window frame member includes: profile elements 31a, 32a, 34a, inner elements 31c, 32c, 34c and intermediate elements 31b, 32b, 34b. Although not pointed out, the side window frame member 33 not shown in the cross-section has a similar configuration to the shown side window frame member 32.

[0102] The intermediate elements 31b, 32b, 34b of the corresponding window frame members 31, 32, 33, 34 form a connection between the profile elements 31a, 32a, 34a and the inner elements 31c, 32c, 34c of the window frame members 31, 32, 33, 34 under discussion. For all four window frame members, the intermediate elements 31b, 32b, 34b of the window frame members 31, 32, 33, 34 can in principle be formed in the same way or formed with individual characteristics. However, generally the two side window frame members 32, 33 of the window frame 3 will be designed to have the same properties.

[0103] Also referring to Figure 12a , in the shown embodiment, the intermediate element 31b of the top window frame member 31 and the intermediate elements 32b, 33b of the two side window frame members 32, 33 are formed as a group of longitudinal profiles, while the intermediate element 34b of the bottom window frame member 34 includes a group of separate fittings, which will be described in more detail in conjunction with Figure 14a -b. The details of the corresponding intermediate elements 31b, 32b, 33b, 34b will be described below.

[0104] The inner elements 31c, 32c, 33c, 34c of the window frame members 31, 32, 33, 34 form a continuous inner element window frame structure that supports the inner edge portion of the pane 4. That is, when viewed from the inside, the edge portion of the pane 4 partially overlaps with the inner elements 31c, 32c, 33c, 34c. In this way, the top edge portion 4c, the side edge portions 4b and the opposite side edge portions, and the bottom edge portion 42b of the inner sheet 42 are all positioned on the outer side of the continuous window frame structure provided by the inner elements, so that any spacers 47 and other elements present along the edge portion of the pane 4 are obscured by the inner elements 31c, 32c, 33c, 34c and are thus not visible from the inside of the building. The inner members 31c, 32c, 33c, 34c of the window frame members 31, 32, 33, 34 can have substantially the same cross-section and be formed of any suitable material, such as wood joined in a mortise joint at the corner. It is also contemplated to form the inner element structure as a completely continuous structure, for example, by molding.

[0105] As will be described in more detail in connection with the following embodiments, the profile elements 31a, 32a, 33a, 34a of the window frame members 31, 32, 33, 34 are positioned along the respective outer edge portions of the pane 4, and the intermediate elements 31b, 32b, 33b, 34b of each window frame member 31, 32, 33, 34 include engaging means 32b3, 34b3 that are configured to form a structural connection with the inner elements 32c, 34c at one of at least two different positions in the height direction.

[0106] Figure 5 and Figure 6 Also indicated in and is the hinge assembly 9 present in the gap between the top window frame member 31 and the top frame member 21, and in the gap between the side window frame member 32 and the side frame member 22. The window frame 3 is connected to the frame 2 by the hinge assembly 9 to provide a top-hung hinge connection.

[0107] Regarding the frame 2 of the roof window 1, each frame member 21, 22, 23, 24 includes a plurality of receiving structures located inside, outside, on the inner side and / or on the outer side of the respective frame member. Each receiving structure is configured to interact with auxiliary devices in the assembled state of the frame 2.

[0108] In the illustrated embodiment, the top frame member 21 and the two side frame members 22, 23 have substantially the same cross-section.

[0109] Particularly referring to Figure 8 and Figure 9, the bottom frame member 24 includes an outer plate 24a and a separate inner plate 24b. The outer plate 24a and the separate inner plate 24b can be formed of the same material as the top frame member 21 and the side frame members 22, 23, such as wood, or as a composite member including plywood and other materials.

[0110] Another feature of the roof window 1 in the illustrated embodiment is that the frame 2 includes at least one releasable member configured to allow replacement with different sets of components to change the function of the roof window 1.

[0111] In the illustrated embodiment, one such releasable member includes a cover 24c that is releasably connected to the remaining parts of the bottom frame member 24 and defines a cavity relative to the remaining parts of the bottom frame member 24. The cover 24c can be formed of any suitable material, such as a profile element of plastic or metallic material.

[0112] Here, the bottom frame member 24 includes an outer plate 24a and a separate inner plate 24b, and the cavity defined by the cover 24c is defined by the inner side portion of the outer plate 24a in the outward direction and is mainly defined by the outer side portion of the separate inner plate 24b towards the interior.

[0113] To obtain a releasable connection, the edge portions 24c1, 24c2 of the cover 24c are received in receiving grooves in the bottom frame member 24, particularly in a receiving groove 24a1 in the outer plate 24a and a receiving groove 24b1 in the separate inner plate 24b.

[0114] In the illustrated embodiment, where the roof window 1 is prepared for manual operation by means of the operating assembly 5, a heat insulator 24d is accommodated in the cavity defined by the cover 24c.

[0115] To change the function of the roof window 1, the cavity defined by the cover 24 is configured to receive an electric operator (not shown), and the cover 24 is configured to be replaced by a different cover (not shown) that allows connection of the operating device of the electric operator to the window frame 3.

[0116] It is also contemplated that a window frame fitting 55 that allows connection to the bottom window frame member 34 can be selectively connected to such an electric operator, in which case the window frame fitting 55 simply duplicates the operating device for the electric operator.

[0117] Similarly, it is contemplated that the roof window 1 is provided in the case where the bottom frame member 24 includes a dummy element configured to be replaced by the socket fitting 51 of the operating assembly 5.

[0118] Accordingly, if the roof window 1 is provided in a basic form of a hinge different from the hinge assembly 9 described in the above embodiments, it is also contemplated to use a blanking plate to cover the hinge assembly receiving serrated edges 29a, 29b to allow the replacement of the previous hinge with the hinge assembly 9.

[0119] The first receiving structure includes lining grooves 25 on the inner sides of each of the frame members 21, 22, 23, 24. The lining grooves 25 are configured to interact with a set of internal lining panels. Such lining panels generally form a transition between the roof window 1 and the internal wall. In the bottom frame member 24, a first groove portion 25a is provided in the outer plate 24a, and a second groove portion 25b is provided in a separate inner plate 24b. In the assembled state of the frame 2, the first groove portion 25a and the second groove portion 25b form the lining groove 25.

[0120] In the illustrated embodiment, when viewed from the inside, each of the frame members 21, 22, 23, 24 includes inwardly projecting portions 21i, 22i, 24i that at least partially overlap the corresponding window frame members 31, 32, 33, 34. This is possible since when the window frame 3 is opened relative to the frame 2, all parts of the window frame 3 move towards the outside.

[0121] The second receiving structure includes sealing grooves 26 located on the outer sides of the inwardly projecting portions 21i, 22i, 24i. The sealing grooves 26 are configured to interact with the frame sealing profile 26p.

[0122] The third receiving structure includes first outer grooves 27 located on the outer sides of the frame members 21, 22, 23, 24. The first outer grooves 27 are configured to interact with the corresponding plates 71, 72, 73, 74 of the heat-insulating frame 7. The interaction can occur by introducing the longitudinal protrusions 78 of the heat-insulating frame plates into the grooves 27 or by correctly positioning separate fastening means.

[0123] Again, from the perspective seen by the user from the inside of the building, with the roof window 1 installed on the roof, it is also noted that the inwardly projecting portions 21i, 22i, 24i of each of the frame members 21, 22, 23, 24 each have an inward-facing surface, and the inward-facing surfaces together form a continuous inward-facing surface. As noted, this appearance mimics the corresponding continuous inward-facing surface of the window frame 3.

[0124] The fourth receiving structure includes engagement unit grooves 28 located on the outer sides of the top frame member 21 and the two side frame members 22, 23. The engagement unit grooves 28 interact with the corresponding top element 81 and side elements 82, 83 of the engagement unit 8, and the function of the engagement unit grooves 28 will be further described below.

[0125] Other details visible in the drawings include guide element 22g (see Figure 7 ) and guide element 32g (see Figure 10 ). Guide element 22g and guide element 32g determine the alignment of window frame 3 relative to frame 2 when closing the window frame, such that any skew occurring in the open position of window frame 3 is eliminated. The masking mounting bracket 32s is visible in Figure 8 . An internal masking device (not shown) can be mounted in window frame 3 via the masking mounting bracket to provide masking for pane 4. The abutting element 22s provides a stop for the bottom window frame member 34 during closing.

[0126] Details of the heat-insulating frame 7 are also shown in these drawings; as mentioned above, the heat-insulating frame 7 includes a top plate 71, side plates 72, 73 and a bottom plate 74. In the illustrated embodiment, each such heat-insulating frame plate includes a protrusion 78 to be received in the outer portion of the corresponding frame member and a recess 75 that interacts with auxiliary equipment having the form of a sleeve under the roof described in more detail in a co-pending patent application of the applicant filed on the same day as this application. With particular reference to Figure 11 , a recess 76 is shown to make room for the mounting bracket 6 to be mounted on the side frame member 23 of frame 2, and a fold line 77 that allows a part of the side plate 73 of the heat-insulating frame 7 to be folded backward to allow access to the outer side of the side frame member 23. Such recesses 76 and fold lines 77 are provided at or near the location where the mounting bracket 6 of a set of mounting brackets for the roof window 1 is positioned on at least the side plates 72, 73 of the heat-insulating frame 7. In principle, the heat-insulating frame 1 can be made of any material with appropriate heat-insulating properties. Currently, it is preferred to use a foam material, such as polyethylene foam.

[0127] Intermediate element- Figures 5 to 16

[0128] Now referring to the description of the connection between the elements of window frame 3, the joining of the intermediate elements 31b, 32b and 33b of the top window frame member 31 with the two side window frame members 32, 33, and with the corresponding internal elements 31c, 32c, 33c will be described first.

[0129] With particular reference to Figure 16 , on the outer side of each internal element, here such as the internal element 32c of the side window frame member 32 shown, there are receiving means configured to receive the joining means of the intermediate element 32b of the side window frame member 32.

[0130] In the illustrated embodiment, the receiving means includes two longitudinally extending grooves 32c1, 32c2 spaced apart from each other in the height direction, and the grooves are open in the outward direction of the roof window 1.

[0131] In the illustrated embodiment, the longitudinal profiles forming the intermediate elements 31b, 32b, 33b have a uniform cross-section and can in principle be cut from one and the same profile length. Preferably, the longitudinal profiles are formed by a continuous molding process, such as extrusion or pultrusion. In particular, the profiles are formed by pultrusion of a composite material combining resin and glass fibers.

[0132] Therefore, only one of these intermediate elements, namely the intermediate element 32b, will be described in detail. Now referring to Figure 15 , the intermediate element 32b includes a base portion 32b1 that extends substantially in the height direction in the assembled state of the window frame 3 and a head portion 32b2 that extends at an angle to the base portion 32b1. As shown in Figure 16 , the base portion 32b1 is provided with engaging means on the inward-facing surface in the assembled state, which surface faces the outer surface of the inner element 32c. Figure 3 , Figure 4 , Figure 5 , Figure 10 and Figure 12a also present the positions, orientations and lengths of the individual intermediate elements 31b, 32b and 33b.

[0133] In the illustrated embodiment, the engaging means of the base portion 32b1 of the intermediate element 32b includes a protruding portion formed as a flange 32b3 that extends over the entire length of the profile and is configured to engage with a selected one of the grooves 32c1, 32c2 of the inner element 32c of the side window frame element 32.

[0134] The base portion 32b1 of each intermediate element 32b includes a stepped portion 32b4 that is offset in the inward direction by an offset bend 32b5 relative to the remainder of the base portion 32b1. The engaging means, here the flange 32b3, is provided in the stepped portion 32b4.

[0135] Additional fastening means 30x (refer to Figure 12a and Figure 16 ) are provided to fasten the intermediate element 32b to the inner element 32c of the side window frame member 32. To receive the additional fastening means 30x, the base portion 32b1 of the intermediate element 32b includes an opening 32b6 configured to receive the additional fastening means 30x, i.e., the opening 32b6 is in the stepped portion 32b4.

[0136] Now referring in particular to Figure 14a and [[ID= , the connection between the intermediate element 34b of the bottom window frame member 34 and the inner element 34c will be described in detail.

[0137] As described above for intermediate elements 31b, 32b, 33b, intermediate element 34b includes a base portion 34b1 extending substantially in the height direction and a head portion 34b2 extending at an angle to the base portion 34b1. The base portion 34b1 is provided on its inner surface with engagement means 34b3, which inner surface faces the outer surface of the inner element 34c. The engagement means of the base portion 34b1 includes projecting portions 34b3 which engage selectively with one of the grooves 34c1, 34c2 of the inner element 34c of the bottom window frame member 34. Additional fastening means 30y are provided in an opening 34b6 in a stepped portion 34b4 offset in an inward direction by an offset bend 34b5 relative to the remainder of the base portion 34b1 to fasten the intermediate element 34b of the bottom window frame member 34 to the inner element 34c.

[0138] In the illustrated embodiment, the intermediate element 34b of the bottom window frame member 34 includes a set of fittings. Two such sets may be provided along the length of the bottom window frame member 34.

[0139] Each set of fittings includes a connecting fitting provided with engagement means configured to form a structural connection with the inner element 34c at one of at least two different positions in the height direction. The connecting fitting includes a first fitting portion 34b0 and a second fitting portion 34b10. The first fitting portion 34b0 includes the engagement means, and the second fitting portion 34b10 is configured to be connected to the first fitting portion 34b0 to serve as a spacer between the outer surface of the inner element 34c of the bottom window frame member 34 and the first fitting portion 34b0. To connect the first fitting portion 34b0 and the second fitting portion 34b10 to each other, the second fitting portion 34b10 is provided with at least one resilient hook-like member 34b11 configured to interact with a corresponding opening 34b12 in the first fitting portion 34b0. In the assembled state of the window frame 3, the head portion 34b2 of the intermediate element 34b of the bottom window frame member 34 is received in a slit 34a5 in an inner portion 34a2 of the profile element 34a of the bottom window frame member 34.

[0140] Comparative embodiments - ​ and ​

[0141] Now referring to ​ and ​ which show a simplified schematic view of the main components of the side window frame member 32, it can be seen how the same components of the window frame 3 can accommodate two window panes 4 of different thicknesses. This is achieved by changing the position of the engagement means of the intermediate element 32b from the first groove 32c1 to the second groove 32c2. This will require a slightly adapted side frame member 22c. The intermediate elements 31b, 33b, 34b at the other window frame members 31, 33, 34 are moved similarly.

[0142] Profile element- ​

[0143] The focus will now be on the profile elements of the window frame 3. In ​ and ​ the overall configuration of the profile element 31a of the top window frame member 31 and the profile elements 32a, 33a of the side window frame members 32, 33 is shown in a perspective view, while the details are shown in a cross-sectional view in ​ . In ​ the profile element 34a of the bottom window frame member 34 is most clearly shown.

[0144] Corresponding to the above, only the profile element 32a of the side window frame member 32 will be described to represent the longitudinal profiles of the top window frame member 31 and the two side window frame members 32, 33, because in the illustrated embodiment, these profile elements are formed as a group of longitudinal profiles having a substantially uniform cross-section.

[0145] The common details of all the profile elements 31a, 32a, 33a, 34a are as follows:

[0146] Each profile element 32a, 34a includes a head portion 32a1, 34a1 and an adjacent outer portion 32a3, 34a3.

[0147] The head portions 32a1, 34a1 are substantially parallel to the plane of the roof window 1 in the assembled state of the roof window 1, while the adjacent outer portions 32a3, 34a3 are substantially perpendicular to the head portions 32a1, 34a1.

[0148] However, the head portion 32a1 of the profile element 32a of each of the top window frame member 31 and the side window frame members 32, 33 is positioned on the outer side of the outer pane surface 4e of the pane 4 and on the outer side of the side edge portion 4b and the top edge portion 4c of the pane 4, while the head portion 34a1 of the profile element 34a of the bottom window frame member 34 is positioned on the inner side of the extension portion 41a of the outer sheet 41 of the pane 4.

[0149] The profile element 32a of the side window frame member 32 and the profile element 34a of the bottom window frame member 34 are thus separated by a layer of glass; however, an overlap is provided by selecting the lengths of the profile elements 32a, 33a of the two side window frame members 32, 33 to substantially correspond to or slightly exceed the distance between the top edge portion 4c of the pane 4 and the bottom edge portion 41b of the outer sheet 41 of the pane 4. The length of the profile element 34a of the bottom window frame member 34 is appropriately selected to substantially extend to the side edge portion 4b of the pane 4.

[0150] The length of the profile element 31a of the top window frame member 31 is selected according to the size of the pane 4 and the manner required to connect the profile element 31a to the profile elements 32a, 33a. In the illustrated embodiment, see ​ , in the assembled state of the window frame 3, the longitudinal profiles form a miter joint between the profile element 31a of the top window frame member 31 and the corresponding profile elements 32a, 33a of the side window frame members 32, 33.

[0151] In ​ it is also visible that the end plug 38 that plugs the profile element 32a of the side window frame member 32. The end plug 38 is provided with ribs and snap arms for increasing friction, which are not described in detail. The glass spacer 45 is provided with a corresponding end plug. In addition, a trailing element 37 is provided to drain any condensate to the profile element seal 34p.

[0152] See ​ , to ensure a tight connection at the miter joint, a corner key 39 is provided at each miter joint. During the manufacturing process, as will be described in particular below with reference to ​ the sealant 39b is applied appropriately.

[0153] The corner key 39 generally has an L-shaped configuration, in which two perpendicular legs 39a1 are separated by a channel 39a2. In the channel 39a2, a set of main openings 39a3 is provided.

[0154] In addition, each leg 39a1 is adjacent to a hanging skirt 39a4 on the first side. Here, secondary openings 39a5 are provided.

[0155] To fit the profiles of the profile elements 31a, 32a, 33a, each leg 39a1 is adjacent to an inclined portion 39a6 on the second side.

[0156] As ​ and ​ shown, the channel 39a2 ends at a tongue 39a7, optionally adjacent to an inclined channel portion 39a8.

[0157] The profile elements 31a, 32a, 33a are appropriately configured to receive the pane 4 in an inverted position, that is, an inverted position in which the corresponding head portion 32a1 faces a substrate such as an assembly table. After the intermediate elements 31b, 32b, 33b have been introduced into the corresponding profile elements 31a, 32a, 33a, this step of assembling the window frame 3 can be carried out. In ​ and ​ it is also visible that the pane holders 4t are placed at appropriate distances from each other along the top edge portion 4c and the side edge portion 4b of the pane 4. In the illustrated embodiment, the interaction between the main components of the window frame 3 is defined by the following configuration of the components:

[0158] Each longitudinal profile of the profile elements 31a forming the top window frame member 31 and the profile elements 32a, 33a of the two side window frame members 32, 33 includes an inner portion 32a2 adjacent to the head portion 32a1. The dimensions are selected such that the inner portion 32a2 overlaps the pane 4 in the assembled state of the window frame 3.

[0159] The head portion 32a1 of each profile element 31a, 32a, 33a is configured to project outward relative to the outer surface 4e of the pane in the assembled state of the window frame 3.

[0160] In the assembled state of the window frame 3, the inner portion 32a2 is inclined relative to the head portion 32a1 from the head portion 32a1 and extends inwardly and extends to the inside toward the outer surface 4e of the pane.

[0161] The inner portion 32a2 abuts a first bending portion 32a4 configured to be located at or near the outer surface 4e of the pane.

[0162] The second bending portion 32a5 is provided as shown, for example, ​ The second bending portion 32a5 has a function of accommodating the seal 4p relative to the outer surface 4e of the pane.

[0163] A third bending portion 32a6 is also provided, and the third bending portion 32a6 is configured to accommodate the inner edge portion 32b9 of the intermediate element 32b relative to the inner side portion of the inner portion 32a2. For a detailed schematic view of the intermediate element 32b, refer to ​

[0164] A transition portion 32a7 is provided between the head portion 32a1 and the inner portion 32a2. The transition portion 32a7 is configured to accommodate the ridge portion 32b7 of the intermediate element 32b.

[0165] The outer portion 32a3 of the adjacent profile element 32a is provided with a fourth bending portion 32a8. The fourth bending portion 32a8 is configured to accommodate the outer edge portion 32b12 of the intermediate element 32b.

[0166] In the assembled state of the window frame 3, the inner portion 32a2 of the profile element 32a is configured to be positioned opposite to the inner inclined portion 32b8 of the intermediate element 32b.

[0167] Finally, the outer edge portion 32b12 of the intermediate element 32b is associated with the head portion 32b2 of the intermediate element 32b via the outer inclined portion 32b11 and the bending portion 32b10.

[0168] ​In summary, the configuration of the described embodiments enables a firm engagement to be provided between the intermediate elements 31b, 32b, 33b and the profile elements 31a, 32a, 33a.

[0169] The lengths of the intermediate elements 32b, 33b of the side window frame members 32, 33 can be selected to be slightly shorter than the associated profile elements 32a, 33a.

[0170] At the bottom window frame member 34, the head portion 34a1 of the profile element 34a is provided with at least one longitudinally extending groove 34a4 for receiving the corresponding sealing strip 4s. These sealing strips 4s can be made of silicone resin to form an adhesive connection between the profile element 34a and the extension 41a of the outer sheet 41 of the window pane 4. A mask 44 can be provided at the extension 41a on the inner side of the outer sheet 41.

[0171] As described above, the intermediate elements 31b, 32b, 33b, 34b of each window frame member 31, 32, 33, 34 include engaging means 32b3, 34b3 configured to form a structural connection with the internal elements 31c, 32c, 33c, 34c. See ​ , to further fasten the intermediate element 34b of the bottom window frame member 34 to the profile element 34a, the head portion 34b2 of the intermediate element 34b is configured to be received in a slit 34a5 in the inner portion 34a2 of the profile element 34a of the bottom window frame member 34 in the assembled state of the window frame 3. To increase the strength of the inner portion 34a2, this portion can be formed as a two-layer folded portion.

[0172] The window frame 3 can in principle be manufactured in any suitable manner. In the following, a currently preferred method will be described:

[0173] In a first step, a set of profiles consisting of three longitudinal profiles is provided. For example, the longitudinal profiles can form a single profile length of an extruded material of a metal such as aluminum. Other materials and manufacturing processes can be envisaged, including roll forming of steel or other metals or roll forming of composite materials.

[0174] Secondly, miter shapes are formed at the mutually facing ends of the longitudinal profiles. If the longitudinal profiles consist of a single length, and if convenient, the miter shapes can be formed in a continuous length by appropriately formed cuts that form internal corners at the intersections between the top and the sides.

[0175] A window pane of appropriate dimensions is provided, for example as described above.

[0176] A set of elements consisting of four internal elements and four intermediate elements is provided, for example as described above.

[0177] The longitudinal profiles are now placed in an inverted position on an assembly table to form a profile element frame structure forming three sides of a rectangle. This is usually achieved by guide elements that can be fixed to the assembly table corresponding to the periphery of the window frame.

[0178] The window pane is placed within a profile element frame structure, and the profile element frame structure is connected to the interior elements to form a window frame, optionally via intermediate elements. During this process, the intermediate elements at the top and sides are typically inserted into the corresponding profile elements. Multiple interior elements can be interconnected as described above to form an interior element frame structure that is placed on the window pane, and then the intermediate elements are connected to the corresponding interior elements.

[0179] Brief reference back ​ Before the pane 4 is placed in the profile element frame structure, a set of two corner keys 39 is advantageously provided, which are placed in the longitudinal profile elements 31a, 32a, 33a at the mutually facing mitered ends. A sealant 39b is preferably applied to each corner key 39. During assembly, it is ensured that the sealant 39b can flow through the main opening 39a3 of the corner key 39 so that the sealant 39b is distributed.

[0180] In the embodiment shown, each angle key 39 is configured to be mechanically connected to the corresponding adjacent profile element 31a, 32a, 33a. This can be done by nailing, for example by Technology to achieve.

[0181] In the embodiment where the roof window 1 comprises one or more glass spacers, such as the glass spacer 45, the glass spacers are aligned on the assembly table before the pane 4 is placed in the profile element frame structure. The glass spacer 45 is provided with one or more adhesive strips 45a fastened to the outer surface 4e of the pane 4.

[0182] Sealing assembly and joining unit- ​

[0183] Now with particular reference ​ , shows an embodiment in which a roof window 1 is provided with a cover assembly 10. Details of the cover assembly 10 generally including a flashing assembly and any other auxiliary equipment are described in more detail in the applicant's co-pending patent application filed on the same day as the present application.

[0184] Hereinafter, the sealing assembly of the roof window 1 will be described. Some details of the sealing assembly have also been described above.

[0185] A sealing assembly typically comprises a set of sealing profiles.

[0186] In the illustrated embodiment, the sealing between the window frame 3 and the frame 2 is provided by an outer sealing plane, an intermediate sealing plane, and an inner sealing plane. Also refer to the cross-sectional views of the top, side, and bottom of the roof window 1 shown and described above.

[0187] The inner sealing plane includes a frame sealing profile 26p provided on the outer side of each frame member 21, 22, 23, 24 and interacting with the inner side of the corresponding window frame member 31, 32, 33, 34.

[0188] The intermediate sealing plane includes a window frame sealing profile 30p1 provided on the outer side of each window frame member 31, 32, 33, 34 and interacting with the inner side of the corresponding frame member 21, 22, 23, 24. The window frame sealing profile 30p1 is provided in a window frame sealing groove 30g1.

[0189] On the bottom side, in the closed position of the window frame 3, an outer sealing plane is provided because the profile element seal 34p on the profile element 34a of the bottom window frame member 34 contacts the outer side of the bottom frame member 34.

[0190] On the top and side, the outer sealing plane is defined by the engagement elements 81, 82, 83. With particular reference to ​ and ​ , the similarities and differences between the top engagement element 81 and the side engagement element, herein represented by the engagement element 82, in the illustrated embodiment will be described:

[0191] Each engagement element 81, 82 includes a base portion 80 having an anchoring portion 801, an inner leg 86, an outer leg 87, a flange 88, and a sealing portion 89. The anchoring portion 801 of the base portion 80 is received in the engagement unit groove 28 in the assembled state of the roof window 1. The sealing portion 89 faces outward and interacts with the top window frame member 31 and the side window frame members 32, 33 during the opening and closing of the window frame 3 and in the closed position of the window frame 3.

[0192] The inner leg 86, the outer leg 87, and the flange 88 together form a channel 810 in the top engagement element 81 and a channel 820 in the side engagement element 82. A corresponding channel is formed in the other side engagement element 83. In this way, water originating from rain or other precipitation can be guided from the channel 810 in the top engagement element 81 to the channels 820 in the side engagement elements 82, 83 and further outward to the cover assembly 10 (not shown in detail).

[0193] What the top engagement element 81 and the side engagement element 82 in the illustrated embodiment have in common is that the sealing portion 89 includes an inner sealing lip 891 and an outer sealing lip 892. Refer to ​ and​ , the inner sealing lips 891 of both the top engaging element 81 and the side engaging element 82 are sufficiently set inward so that the inner sealing lips 891 interact with the interiors of the top window frame member 31 and the side window frame member 32; however, the outer sealing lip 892 of the top engaging element 81 is positioned on the outer side portion of the top window frame member 31. In the illustrated embodiment, this is due to the fact that the flange 88 of the top engaging element 81 is longer than the corresponding flange of the side engaging element 82. Note that although at least the sealing portions 89 of each engaging element 81, 82, 83 are formed to be elastic, i.e., as is characteristic of a seal, the sealing portion 89 is capable of deforming when abutted against another component and then rebounding when relaxed, this is not reflected in the drawings as the drawings typically show the elements in their undeformed state. Generally, at least the sealing portion 89 has different characteristics from at least the base portion 80. This can be provided by co-extruding or co-molding two (or more) different materials.

[0194] To ensure a tight interaction at the top of the roof window 1, also referring to ​ , the top engaging element 81 includes an additional inner sealing lip 893, a first additional outer sealing lip 894, and a second additional outer sealing lip 895.

[0195] In the illustrated embodiment, since the base portion 80, the inner leg 86, and the flange 88 form a flashing receiving groove 85, the engaging elements 81, 82, 83 also allow interaction with the cover assembly 10. The flashing receiving groove 85 has a groove opening 85b and is provided with a plurality of protrusions 85a.

[0196] The seal assembly further includes a pane seal 30p2 received in the pane seal groove 30g2. Note that the pane seal 30p2 remains fixed relative to the window frame 3.

[0197] Now referring to ​ , the details of an alternative embodiment will be described. Only the differences from the above-described embodiment will be described in detail.

[0198] In ​ , a foam element 32f present in the side window frame member 32 is shown. Similar foam elements may also be present in the opposite side window frame member 33. The longitudinal extent of the foam element 32f may be such that the foam element 32f extends over a majority of the length of the side window frame member 32. The foam element 32f abuts against the inner side portion of the head portion 32b2 of the intermediate element 32b along the extent of the intermediate element 32b, and allows the foam element 32f to expand towards the inner side portion of the head portion 32a1 of the profile element 32a of the side window frame member 32 at the portion where the foam element 32f protrudes beyond the longitudinal end of the intermediate element 32b. The foam element 32f has general weather protection properties.

[0199] In ​ it, the stabilizing plate 310x is placed in the channel 810 of the top element 81 of the engaging unit 8 to improve the structural characteristics. In addition, the extension plate 310y is shown fastened to the profile element 31a of the top window frame member 31 to project into the channel 810. The extension plate 310y improves the guidance of precipitation into the channel 810 and is used to further guide it towards the sides of the roof window. This is particularly relevant in the case of roof windows built on steeply pitched roofs. In ​ the relative positions of the stabilizing plate 310x and the extension plate 310y are shown more clearly. To facilitate viewing of the relevant part of the engaging unit 8, ​ the top element 81 of the engaging unit 8 is shown without the stabilizing plate 310x and with the window frame 3 including the extension plate 310y.

[0200] ​ The interaction between the bottom of the roof window 1 and the cover assembly 10 is shown.

[0201] Finally, ​ a view of the lower right corner of the roof window 1 is shown, where for reasons of clarity, the window frame 3 is slightly lifted relative to the frame 2.

[0202] Here, the clip 22x is mounted on the side element 82 of the engaging unit 8. The clip 22x is provided with a clip flange 22xa, as shown in more detail in ​ it. The end plug 38 of the side window frame member 32 is provided with an end plug flange 38a in this embodiment. In the closed position of the roof window 1, the end plug flange 38a overlaps with the clip flange 22xa.

[0203] Generally speaking, the components of the roof window are easy to disassemble, and each component can in principle be reused, recycled or have its materials reclaimed for other uses by appropriate environmentally responsible treatment means.
