Description

TECHNICAL FIELD

[0001] The utility model relates to a waterproof member for covering a gap between a first roof penetration structure and a second roof penetration structure, the waterproof member comprising a first engagement section configured for engagement with the first roof penetration structure, a second engagement section configured for engagement with the second roof penetration structure, and a connecting section extending between the first engagement section and the second engagement section, the connecting section defining a first plane. BACKGROUND

[0002] Generally, in the field of installation of roof penetration structures, there is always a need to provide a convenient waterproof solution that provides weather protection of the transition area between the roof and the roof penetration structure and is reliable and easy to install. For the special case where two roof penetration structures are placed in close proximity to each other, the space between the structures cannot provide enough space to cover this area with conventional waterproof solutions, and therefore special waterproofing is required. Waterproof solutions for two adjacently placed roof penetration structures have been developed. For example, a waterproof assembly for roof windows installed next to each other is disclosed in DK 154099. The waterproof assembly provides excellent weather protection, but there is still a need for a waterproof assembly that is easier to install.

[0003] With the increasing awareness of sustainability, the requirements for reduction and optimization of materials, reuse, recycling, and recycling are strict in terms of modern building components. Further, this means that the components of the roof structure, including roof windows and waterproof assemblies, not only need to be sustainably manufactured, transported, and installed, but they also need to be easily disassembled.

[0004] Although such existing waterproof assemblies generally provide a relatively good functional solution, there is still room for improvement. SUMMARY

[0005] It is therefore an object of the utility model to provide a waterproof member that makes the waterproof assembly universal and easy to install. Another object is to provide a waterproof assembly that is easy to remove after installation.

[0006] The objects and other objects are achieved by a waterproof member of the type mentioned in the introduction, characterized in that the width of the connecting section is variable, and the waterproof member further comprises a first protrusion and a second protrusion, both protruding away from the first plane, and the first engagement section and the second engagement section are flat and extend parallel to the first plane.

[0007] Since the first and second joint sections are flat, the connection between the waterproofing member and the first and second roof penetration structures enables a low installation height, i.e. a low height from the groove formed between the first and second protrusions to the joint with the roof penetration structures. This is advantageous since the space available for such a waterproofing member is typically small in the height direction, i.e. in a direction perpendicular to the first plane. For example, in a situation where two roof penetration structures are installed on each side of a rafter and the roof penetration structures do not protrude too much beyond the rafter - which is desirable since this provides less exposed surface which can introduce heat loss - the space available for installing the waterproofing member is limited by the two waterproofing member receiving grooves and the rafter at the bottom. Furthermore, it is desirable to keep a low profile towards the top to reduce the surface of attack for the wind. Thus, even a shallow gap can be waterproofed in an appropriate manner.

[0008] As mentioned, it is desirable to keep a low profile with the roof penetration structures, and thus, the roof, such as roof tiles, will make it impossible to insert the waterproofing member into the waterproofing member receiving groove from a direction parallel to the main extension of the first or second waterproofing member receiving groove. The ability to change width allows the waterproofing member of the present embodiment to be inserted in a direction perpendicular to the direction parallel to the main extension of the first or second waterproofing member receiving groove. In this way, the waterproofing member can be provided in a supply state where the first and second joint sections are engaged with each other, but where the waterproofing member is in a non-deployed position, and the waterproofing member can be brought into an installed state by first lowering the waterproofing member into the gap so that the bottom of the groove formed by the connection sections is positioned at approximately the same level as the part of the roof structure located in the gap, and secondly moving the first and second joint sections in mutually opposite directions and into engagement with the first and second roof penetration structures.

[0009] Furthermore, the presence of the first and second protrusions makes it possible to provide protection of the part of the roof penetration structure that interacts with the waterproofing member. This is particularly advantageous in a roof penetration structure comprising a roof window having a joint unit that interacts with the joint sections of the waterproofing member.

[0010] Finally, the first and second protrusions not only facilitate installation, but also removal; during installation, the installer can manually push the protrusions or can push the protrusions by means of a suitable tool, such as a hammer, to move the waterproofing member into place. Conversely, in the event that the waterproofing member needs to be removed, the protrusions can be moved in a direction towards each other, manually or with the aid of a suitable tool, such as a spade.

[0011] The term "first plane" is configured to encompass any plane extending between the upper surface and the lower surface of the connection section.

[0012] In one embodiment, the first and second engagement sections are substantially coincident with the first plane. By forming the first and second engagement sections not only flat but also substantially coincident with the first plane, the connection between the waterproofing member and the first and second roof penetration structures is substantially flush with the groove formed between the first and second protrusions.

[0013] The term "substantially coincident" is configured to encompass a small variation in level; for example, a difference in level in the range of 1 mm to 5 mm.

[0014] In some embodiments, the first and second protrusions protrude away from the first plane in a perpendicular manner. The protrusions thus provide a holding portion for the operator to exert a force in two directions, either towards or away from the respective structure.

[0015] In some embodiments, the connection section comprises a first portion and a second portion, wherein the first portion is configured to be displaceable in a slidable manner relative to the second portion. The first and second portions allow the waterproofing member to be deployed in a mechanically simple but reliable manner in the width dimension with said two portions moved relative to each other.

[0016] In some embodiments, the first portion comprises a first engagement portion and the second portion comprises a second engagement portion, wherein the first and second engagement portions are configured to engage with each other to prevent the first and second portions from separating.

[0017] In a further improvement of the above-mentioned embodiments, the first portion comprises a first leg portion and a second leg portion, a recess being formed between the first and second leg portions, and the second portion comprises a leg portion that can be inserted into said recess to form a telescopic joint. This provides a reliable joint between the two portions of the waterproofing member, notwithstanding the fact that the two portions of the waterproofing member are fully adjustable between a maximum width and a minimum width.

[0018] In an alternative embodiment, the connection section comprises a corrugated portion. The corrugated portion allows the waterproofing member to be deployed in the width direction and thus to be inserted into shallow gaps and then deployed in the shallow gaps to make these gaps waterproof. The advantage of this embodiment is that the waterproofing member can be provided as a monolithic component, thereby eliminating any risk of disassembly of the components during transport and / or handling.

[0019] Other presently preferred embodiments and further advantages will be apparent from the following detailed description and from the drawings.

[0020] Features described in relation to one of these aspects can also be incorporated into another aspect and the advantages of that feature apply to all aspects into which it is incorporated. BRIEF DESCRIPTION OF DRAWINGS

[0044] In the following, a detailed description of embodiments of the present application will be given with reference to the accompanying drawings. From the FIG. 1A At the outset, an embodiment of a water protection member 1 is shown which is configured for covering a gap between a first roof penetration structure 100 and a second roof penetration structure 200. As indicated, the roof penetration structures 100, 200 can be represented by the joining units of the respective side members of a fixed frame which represents a roof window installed in a tilted roof structure (not shown) adjacent to each other in a side-by-side manner.

[0045] The water protection member 1 is located above the roof penetration structures 100, 200, i.e. at a horizontal level closer to the outside than the roof penetration structures 100, 200. The water protection member 1 comprises a first joining section 13 and a second joining section 23, both of which are configured to be received in a water protection member receiving groove 102, 202 of the roof penetration structures 100, 200. The water protection member receiving groove can extend along the entire side of the roof penetration structures 100, 200. The first joining section 13 and the second joining section 23 are connected by a connecting section 2. The connecting section 2 defines a first plane PI which extends approximately between an upper surface 2a and a lower surface 2b of the connecting section 2.

[0046] The water protection member 1 is expandable in its width dimension. The connecting section 2 is configured to be variable in its width and thereby makes the water protection member 1 expandable. The width dimension can be understood as the dimension extending from left to right in FIGS. 1A-1C and FIGS. 2A-2C .

[0047] In the embodiment of FIGS. 1A-1C , the connecting section 2 comprises a first portion 10 and a second portion 20. The first portion 10 is formed such that it is slidable with respect to the second portion 20. Thus, it can be said that the first portion 10 receives the second portion 20 as will be described in further detail herein.

[0048] In the shown embodiment, the first portion 10 and the second portion 20 are each formed as a substantially longitudinally extending profile element having a length direction which, in the installation situation to be described in the following, is parallel to the inclination direction D of the roof structure and extends into the drawing plane in Fig. 1.

[0049] As will be described in the following with reference to FIG. 3In further detail, the upper surface 2a of the connection section 2 is formed on the first leg portion of the first portion 10 of the waterproofing member 1, while the lower surface 2b is formed on the second leg portion of the first portion 10, thereby delimiting a slit-shaped recess into which the second portion 20 can be inserted by the leg portions and can slide in order to provide the target of adjustability of the waterproofing member 1.

[0050] FIG. 1A In the middle, a portion of the roof structure 500 is also shown, which can limit the depth of the waterproofing member 1 in the installed state.

[0051] The first roof penetration structure 100 and the second roof penetration structure 200 can be roof windows, but other structures such as solar panels can also be envisaged.

[0052] The waterproofing member 1 also comprises a first protrusion 11 and a second protrusion 21. The first protrusion 11 is located between the first joint section 13 and the connection section 2. The second protrusion 21 is located between the second joint section 23 and the connection section 2. In the case where the gap between two adjacent roof penetration structures is to be waterproofed, the waterproofing member 1 is inserted into the gap between the first roof penetration structure 100 and the second roof penetration structure 200.

[0053] In FIG. 1A In the middle, the waterproofing member 1 is shown in an assembled but not yet unfolded position. This position can for example correspond to the supply state of the waterproofing member 1.

[0054] Since the width of the waterproofing member 1 is smaller than the width of the gap, the waterproofing member 1 can be inserted into the gap from the top. In FIG. 1B An embodiment of the waterproofing member 1 inserted into the gap can be seen in the middle, wherein the waterproofing member 1 assumes an intermediate position, i.e. the waterproofing member 1 is positioned within the gap between the roof penetration structures 100, 200 and is ready to be connected to the waterproofing piece receiving grooves 102, 202.

[0055] Once the waterproofing member 1 is inserted into the gap and thus positioned at the appropriate height with respect to the roof penetration structures 100, 200, a force is applied in the direction F2 to the exposed first protrusion 11 to insert the first joint section 13 into the first waterproofing piece receiving groove 102. A force in the opposite orientation in the direction F3 unfolds the connection section 2 in the width direction and inserts the second joint section 23 into the second waterproofing piece receiving groove 202. In FIG. 1C The unfolded waterproofing member 1 is shown in the middle in cross-sectional form, wherein the first joint section 13 and the second joint section 23 are inserted into the waterproofing piece receiving grooves 102, 202. Now, the waterproofing member 1 assumes a position corresponding to the installed state of the waterproofing member 1.

[0056] To prevent the first part 10 and the second part 20 from separating, for example in the supply state and in the installed state, and thus impairing the weatherproofness of the weatherproofing member 1, the first part 10 comprises a first engagement portion 12 and the second part 20 comprises a second engagement portion 22. These engagement portions 12, 22 can be formed as folded portions which engage with one another to prevent unfolding beyond a degree which would jeopardise the weatherproofness of the weatherproofing member 1. For example, the first part 10 and the second part 20 can be made of a sheet material substantially as shown in FIGS. 1A-1C .

[0057] The weatherproofing member 1 as a whole can be made of a sheet material formed by parallel folded portions or bends. In particular, the first and second protruding portions 11, 21 and the first and second engagement portions 12, 22 can be formed by bending a sheet-like material such as a metal sheet. However, the weatherproofing member 1 can in principle be formed by extrusion, as indicated in the embodiment of FIGS. 1A-1C .

[0058] In FIG. 2A , an alternative embodiment of the weatherproofing member 1 is shown in which the connection section 2 comprises a corrugated portion 30 which is configured to be stretched to provide a variable width to the weatherproofing member 1. The corrugated portion 30 can be formed such that it does not increase the depth of the weatherproofing member 1 substantially below the first and second engagement sections. This means that almost all of the corrugated portion 30 can be positioned above the first and second engagement sections 13, 23. This is important because it allows the weatherproofing member 1 to waterproof shallow gaps, which would otherwise be at risk of the corrugated portion colliding with the roof structure. The weatherproofing member 1 can thus be said to have a non-protruding character. In a preferred embodiment, the weatherproofing member 1 does not protrude towards the roof in the installed state by more than 30 mm. The weatherproofing member can thus be used to waterproof gaps between roof penetration structures which are installed relatively low with respect to the roof and span a portion of the roof structure 500 which is higher in the roof structure, i.e. towards the outer surface of the roof, for example a roof rafter, without having to modify such a roof structure. The first plane can be defined as the plane containing all of the lower folds of the corrugated section 30.

[0059] As shown, the first weatherproofing member receiving recess 102 of the first roof penetration structure 100 can comprise a first sealing protrusion 101 configured to be in sealing contact with the first engagement section 13. The same can apply mutatis mutandis to the second weatherproofing member receiving recess 202, which in the embodiment shown comprises a second sealing protrusion 201.

[0060] The first and second protrusions 11, 21 can extend from the first plane a distance of at least 15 mm. This can facilitate the use of the protrusions to push the joint sections into or out of the waterproofing piece receiving grooves. The height of the protrusions 11, 21 contributes to the protrusions 11, 21 receiving forces that can be exerted on the protrusions 11, 21 by hand or a tool adapted to exert force on such structures, for example a mallet or a hammer. The height of the protrusions can be beneficial because each protrusion 11, 21 covers the upper half of the respective waterproofing piece receiving groove 102, 202 and thereby protects the sealing protrusion 101, 201 from radiation from the sun, wind, rain, dust or dirt.

[0061] In the following, the installation of the waterproofing member 1 for covering the gap between the first and second roof penetration structures will be described in some detail.

[0062] The installation of the waterproofing member 1 will be described with particular reference to the embodiments described above and shown in FIGS. 1A-1C and FIGS. 2A-2C in connection with the first and second roof penetration structures 100, 200.

[0063] The first step comprises inserting the waterproofing member 1 between the first and second roof penetration structures 100, 200. The arrow F1 indicates the movement of the waterproofing member required to position the waterproofing member 1 in the gap. Thereafter, the waterproofing member 1 can be unfolded in the direction of the forces indicated by F2, F3. For the sake of simplicity, the procedure is described for the first joint section 13, but it is applicable to the second joint section 23 mutatis mutandis. First, the protrusion 11 is moved towards the first roof penetration structure 100 and the first joint section 13 is inserted into the first waterproofing piece receiving groove 102, the first joint section 13 being held in the first waterproofing piece receiving groove 102 by the sealing protrusion 101. Thereafter, the second protrusion 21 is moved in the direction of the second roof penetration structure 200 and the second joint section 23 is inserted into the second waterproofing piece receiving groove 202, the second joint section 23 being held in the second waterproofing piece receiving groove 202 by the second sealing protrusion 201. This step also unfolds the waterproofing member 1 and closes the gap between the first and second roof penetration structures 100, 200. Alternatively, the first and second protrusions can be moved towards the first and second waterproofing piece receiving grooves, respectively, simultaneously, achieving the same unfolding and closure of the gap. Other combinations of movement patterns can even be envisaged.

[0064] By the configuration of the waterproof member 1 according to the present utility model, it can also include a step of disengaging the waterproof member 1 from the first roof penetration structure 100 and the second roof penetration structure 200 by pulling the first engagement section 13 out of the first waterproof member receiving groove 102 by exerting a force on the first protruding section 11. This is a major advantage in case the waterproof member needs to be removed from the gap in the installed state, for example when a part of the roof located under the waterproof member needs to be accessed. To this end, a spade-like object can be wedged into the space between the first protruding section 11 and the first roof penetration structure 100. This allows the user to exert the force to pull the first engagement section out of the first waterproof member receiving groove 102.

[0065] In the following, two further embodiments will be described with reference to FIG. 3 and FIG. 4 two further embodiments, FIG. 3 and FIG. 4 a waterproof member 1 in a tilted position is shown, which tilted position indicates an exemplary position assumed by the waterproof member 1 in the installed state between two adjacent roof penetration structures (not shown). Elements having the same or similar function as in the embodiments shown in Figs. 1 and 2 above are always denoted by the same reference numerals. Only the differences to these embodiments will be described in detail.

[0066] In FIG. 3 , an embodiment of a waterproof member 1 is shown, which corresponds to FIGS. 1A-1C an embodiment of a two-part waterproof member 1 comprising a first part 10 and a second part 20. In the shown embodiment, both the first part 10 and the second part 20 are formed by folding a sheet material, such as a suitable metal material, with a bend to form the first part 10 and the second part 20 as follows.

[0067] The first part 10 comprises a first leg part 10a and a second leg part 10b, between which a pocket 10c is formed. The first leg part 10a is formed by folding the material onto itself to form a double-walled structure. The second leg part 10b is positioned with a gap relative to the lower wall of the first leg part 10a, so that the formed pocket 10c is substantially slit-shaped. A first engagement section 12 is formed at the free end edge of the second leg part 10b, which here acts as a flange formed by bending back more than 90 degrees and less than 180 degrees relative to the second leg part 10b.

[0068] The second part 20 comprises a leg portion 20a which is insertable into the recess 10c of the first part 10 to form a telescopic joint. The free end of the leg portion 20a comprises a second engagement portion 22 which here is formed as a flange by bending it backwards by an angle of more than 90 degrees and less than 180 degrees relative to the leg portion 20a.

[0069] FIG. 3 The following general directions are also indicated in the middle: the oblique direction D, the width direction W and the height direction H.

[0070] It should be noted that in order to make the second engagement section 23 coincide with the plane of the first engagement section 13, the bend connecting the second engagement section 23 and the second protrusion 21 has a different height than the bend connecting the second protrusion 21 and the leg portion 20a. This compensates for the fact that the second part 20 is partly located below the first part 10 which is partly located above, thus allowing the leg portion 20a of the second part 20 to be inserted into the slit-shaped recess 10c formed in the first part 10 in the width direction W. Thus, in a configuration where the roof penetration structures 100, 200 are at the same height, the engagement sections 13, 23 are parallel to the roof and are positioned in approximately the same plane in the height direction H, which can be beneficial for forming a tight seal with the sealing protrusions 101, 201 of the roof penetration structures 100, 200.

[0071] In FIG. 4 embodiments of the waterproofing member 1 with a corrugated portion 30 are shown, and FIG. 4 the corrugated portion in

[0072] Now turning to FIG. 5 which shows the waterproofing member 1 in an embodiment of the waterproofing member 1 in its installed state between two adjacent roof penetration structures in the form of roof windows 100, 200. FIG. 3

[0073] The configuration of such roof windows, comprising an engagement unit forming the point of interaction with the waterproofing assembly of a single, standalone roof window, is described in more detail in the applicant’s published international application WO 2023 / 186250 Al.

[0074] As FIG. 5 ​As shown, the first engagement section 13 of the first part 10 of the waterproofing member 1 is inserted into the first waterproofing member receiving groove 102 of the engagement unit of the left side roof window 100 and the second engagement section 23 of the second part 20 is inserted into the second waterproofing member receiving groove 202 of the engagement unit of the right side roof window 200. The first protrusion 11 is urged into engagement with the engagement unit of the left side roof window 100 and correspondingly the second protrusion 21 with the engagement unit of the right side roof window 200, so that the water tightness is ensured just because the respective protrusions 11, 21 protect the engagement unit from the ambient environment by partially or completely covering the openings to the waterproofing member receiving grooves 102, 202.

[0075] With particular reference to FIGS. 6-8 More details are shown of FIG. 3 the interaction between the first part 10 and the second part 20 of the two-part waterproofing member 1 of the embodiment:

[0076] During assembly of the waterproofing member 1, the second part 20 is introduced into the pocket 10c formed between the first leg portion 10a and the second leg portion 10b of the first part 10 by its leg portion 20a comprising the second engagement portion 22. Upon passage of the second engagement portion 22 past the first engagement portion 12, one or both of the first part 10 and the second part 20 yield to achieve engagement.

[0077] Once engaged, the mutual position of the first part 10 and the second part 20 can be adjusted as needed.

[0078] In FIG. 7 the position shown, a maximum measure D 最大 of the distance between the first protrusion 11 and the second protrusion 12 is indicated. As shown, the first engagement portion 12 is engaged with the second engagement portion 22, thus preventing the first part 10 and the second part 20 from separating.

[0079] In FIG. 8 the position shown, a minimum measure D 最小 is indicated. At this position, the leg portion 20a of the second part 20 has been inserted into the pocket 10c to its maximum extent.

[0080] Turning now to FIGS. 9-18B , further aspects of the utility model will be described in considerable detail with reference to a roof structure comprising four roof penetration structures 100, 200, 300, 400. Elements having the same or similar function as in the above described embodiments bear the same reference numerals.

[0081] The two lowermost roof-penetrating structures 100, 200 are each provided with a bottom water-proofing member 144, 244, which forms part of the water-proofing assembly, when viewed in the oblique direction D.

[0082] Other components of the water-proofing assembly include a set of two-part water-proofing members 1 of the type described with reference to Figs. 1 to FIG. 8 A set of components of a two-part water-proofing member 1 of the type described. Two different second parts 20 and 20’ are selected, respectively, according to the spacing in the width direction W between pairs of adjacent roof-penetrating structures 100, 200 and 300, 400, as indicated. FIG. 11A and FIG. 11B .

[0083] As shown in FIG. 12 , a first part 10 is provided. The first part 10 is formed with a first leg portion and a second leg portion, between which a recess (not indicated in detail) is formed, substantially as shown in FIG. 7 and FIG. 8 . Furthermore, the first part 10 comprises a first protrusion 11 (see FIG. 17 ).

[0084] It should be noted that, contrary to the embodiments of the parts of the water-proofing member shown in Figs. 1 to FIG. 8 , FIGS. 11A-18B the first part 10 and the second part 20; 20’ shown in Figs. 1 to 3 do not comprise respective flat joint sections parallel to the first plane P. However, the presently described principles are generally applicable to water-proofing members having such flat joint sections and to water-proofing members not having such flat joint sections.

[0085] In order to further improve the installation conditions, the water-proofing assembly is provided with a retaining device. The retaining device can be temporary to provide temporary retention in the installation step, or can form part of a permanent structure fixing the water-proofing assembly to the roof-penetrating structures or to the roof structure.

[0086] The retaining device ensures that the water-proofing members are positioned between adjacent roof-penetrating structures with their length direction parallel to the oblique direction.

[0087] The retaining device can be form-fitting or non-form-fitting.

[0088] The term "form-fitting engagement" (German: formschlüssig) shall be interpreted to encompass a mechanical coupling of two originally separate components, such that the design and geometry of the components will prevent such coupling from being released unintentionally due to forces experienced by the components during use, which particularly includes such mechanical couplings in which the respective components, which are complementary in shape, fit together in the engaged position, and in which at least one of the components needs to be moved intentionally when leaving the engaged position, which typically involves one or more portions of one or both components being moved at least partially in a direction at an angle to the intended motion. In other words, the term "form-fitting engagement" shall be understood as any form of form-locked coupling in which the shape or geometry of the two components interlock with each other such that the two components create an engagement that prevents disengagement until intentional release by a user's active or conscious action.

[0089] In contrast thereto, "non-form-fitting engagement" (German: kraftschlüssig) relates to an engagement that only requires a force in the intended direction of motion to enable release. A non-exhaustive list of examples of non-form-fitting engagement means includes frictional connections, magnetic connections, "soft" snap connections, etc., in which the engagement between the components is primarily achieved by means of forces in tangential direction and not in normal direction.

[0090] The retaining device can be disposed on any waterproofing member of the waterproofing assembly.

[0091] The retaining device can comprise a substantially planar lug extending in a plane substantially parallel to any plane spanned by portions of the waterproofing member. The planar lug can be formed to extend in a plane spanned by the height direction H and the inclination direction D of the waterproofing member.

[0092] Such one or more planar lugs can be formed to protrude from the waterproofing member.

[0093] The shape of each planar lug can be chosen arbitrarily to comply with manufacturing, shipping or installation requirements.

[0094] Each planar lug can be foldable about a fold line substantially parallel to the height direction H or the inclination direction D.

[0095] In FIG. 16 and FIG. 17 In a more detailed embodiment, a substantially planar lug 14 is formed on a bottom waterproofing member 144 of the first roof penetration structure 100.

[0096] The planar lug 14 here has a trapezoidal shape and protrudes from a vertical flange of the bottom waterproofing member 144 to extend in a plane spanned by the height direction H and the inclination direction D.

[0097] The planar lug 14 is configured to be foldable about a fold line substantially parallel to the inclination direction D to abut the first protrusion 11 of the first portion 10 of the waterproof member 1 in the installed condition of the waterproof assembly.

[0098] Therefore, in the installed condition, the trapezoidal lug 14 assumes a folded-back position substantially parallel to its original plane and acts as a force-locked engagement device to prevent the waterproof member 1 from sliding along the inclined roof by means of friction.

[0099] This engagement can be reinforced by manually, possibly with the aid of suitable tools, clamping the trapezoidal lug 14.

[0100] In the installed condition of the waterproof assembly, the trapezoidal lug 14 is arranged to abut the first protrusion 11 of the first portion 10 of the waterproof member 1. FIG. 18A and FIG. 18B In a more detailed embodiment, a substantially planar lug 15 is formed on the first protrusion 11 of the first portion 10 of the waterproof member 1.

[0101] The planar lug 15 has a rectangular shape and protrudes from the first protrusion 11 so as to extend in a plane spanned by the height direction H and the inclination direction D.

[0102] The planar lug 15 is configured to be foldable about a fold line substantially parallel to the height direction H to a position at right angles to its original plane to abut a portion of the first roof penetration structure 100, typically at a corner of a fixed frame of a roof window or at a portion of any insulation frame mounted to the frame. In this way, the rectangular lug 15 provides a form-locked engagement with the first roof penetration structure 100, thus further improving the retention of the waterproof member 1.
