Description

DK 181528 B1 1
Technical Field
The present invention relates to an underroof collar for use with a roof window mounted in a roof structure inclined in a direction of inclination, wherein said roof window comprises a frame delimiting a frame opening and having an outer side facing away from the frame opening, wherein said underroof collar comprises an inner portion, which is configured for extending along the outer side of the frame of the roof window, and an outer portion, which is configured for extending away from the roof window and for overlapping with sections of an underroof extending along the roof window, said inner portion delimiting a collar opening, and wherein said underroof collar comprises a plurality of collar members each having a length direction extending along the collar opening.
The invention further relates to a method for sealing the joint between a roof window mounted in a roof structure inclined in a direction of inclination and an underroof of said roof structure.
Background Art in roofs covered by tiles and other roofing materials an underroof is typically provided underneath the roofing material to divert any precipitation penetrating through the roofing material, for example snow entering through small gaps between tiles, and any condensation forming on the interior side of (the roofing material. in this context the term “interior” is used to indicate a direction towards the interior of a building covered by the roof, and the term “exterior” is used for the opposite direction, away from the interior of the building.
When a roof window is mounted in the roof, an opening is cut in the roof structure, thereby interrupting the underroof. After mounting of the roof window in said opening, an underroof collar is used for sealing the joint between the roof window and the underroof. The inner portion of the underroof collar is typically attached to the frame of the roof window, for example by
DK 181528 B1 2 means of staples or an adhesive, and the outer portion of the underroof collar, also referred to as a skirt portion, overlaps with the sections of the underroof extending along the opening closest to the roof window. The outer portion may be attached to the roof structure, for example by means of staples, and/or to the underroof, for examples by means of adhesive tape, thereby keeping the underroof collar in its intended position. In some roof structures, laths for supporting the roofing material extend on the exterior side of the underroaf. To be able to reach over such laths and down to the underroof between them, at least the outer portion of the side collar members of the underroof collar may be provided with a surplus of material, for example being made from a pleated material. Examples of underroof collars are disclosed in EP09949092B1,
EP1774118B1, EP1896673B1, and EP2284329A2.
The underroof collars are typically made from a textile material, such as a non-woven material, which is waterproof but vapour-permeable, and flashing and covering members are arranged on top of the underroof collars to protect them from weather and mechanical wear.
Attempts have been made to facilitate mounting of an underroof collar by making the inner portion of the underroof collar from an elastic material, by fixating a pleating or folding of the outer portion of the underroof collar so that it only unfolds when the surplus of material is needed, and by packaging the underroof collar in a manner, which eases unpacking and mounting. Improved handieability of underroof collars during mounting in roof structures, however, continues to be desired by installers.
Summary of Invention
With this background, it is therefore an object of the invention to provide an alternative underroof collar, which makes the work of the installer easier.
This and further objects are achieved with a underroof collar of the kind mentioned in the introduction which is furthermore characterised in that the underroof collar further comprises at least one attachment member, which is attached to the inner portion and which is configured for being inserted in an
DK 181528 B1 3 opening at the frame of the roof window, and that the/each attachment member is provided with a barb.
The provision of an attachment member on the underroof collar configured for being inserted in an opening not only aliows for a relatively easy installation of the underroof collar as the attachment member(s) can simply be inserted in the opening(s), but it also increases the likelihood of the inner portion of the underroof collar actually being attached. Adhesive on the inner portion, as has been used in the prior art, will typically be covered by a cover strip in the state of delivery of the underroof collar, and it happens that the installer forgets to remove the cover strip. Attachment members are less likely to be overlooked or forgotten, as they will typically be more distinct from the other parts of the underroof collar, typically being made from a stiffer material.
Another advantage of the attachment members over the adhesive is that there is virtually no risk of the attachment members sticking together or sticking to other parts of the underroof collar, which is a known problem with adhesives, particularly when handling underroof collars in windy conditions.
The opening at the frame of the roof window may be an opening in the frame itself, an opening in an insulating frame arranged around the frame during installation of the roof window, or an opening formed between the frame of the roof window and such an insulating frame. An opening formed between the frame of the roof window and an insulating frame may preferably extend substantially in parallel to the outer side of the frame. it is presently preferred that at least one attachment member is provided on each collar member. This will help to ensure that all collar members are arranged correctly in relation to the frame of the roof window.
By the/each attachment member being provided with a barb the risk of the attachment member being detached from the opening, as may for example happen if wind pulls on the underroof collar during installation or if the installer pulls on other collar members to get the underroof collar in place, is reduced.
The barb may be configured for engaging with an insulating frame, which is typically made from an elastic material, in which case the barb may form an indentation in the material of the insulating frame by compressing it. It is,
DK 181528 B1 4 however, also possible to pre-form an indentation for engagement with the barb, either in an insulating frame or in the frame of the roof window, It is also, or alternatively, possible for the attachment member to be made from an elastic material, so that it may deflect during insertion into the opening and snap into a locking engagement with the frame of the roof window and/or the insulating frame. The locking engagement may be established by friction and/or by mechanical means.
The attachment member may be a local member, in which case each collar member is preferably provided with two or more attachment members, but in one embodiment an attachment member extends over substantially the entire length of a collar member in the length direction. in addition to providing a continuous attachment, an attachment member extending over substantially the entire length of the collar member may provide stiffness to the inner portion of the underroaf collar, which may facilitate installation. To facilitate storage and packaging, such an attachment member may be provided with one or more hinges or weakenings allowing the colfar member to be folded. Furthermore, an attachment member extending over substantially the entire length of a collar member may provide improved weather proofing compared to when using local attachment members, since the underroof collar may be kept in tight contact with the frame of the roof window over the entire length of the attachment member and hence substantially the entire length of a collar member.
An attachment member extending over substantially the entire length of a collar member will typically be inserted in a groove extending over the entire length of a corresponding member of the frame of roof window, either being formed in the frame itself or in an insulating frame or between the frame and an insulating frame, said groove constituting the opening. In case the groove is formed in an insulating frame or between the frame of the roof window and an insulating frame, the groove and possibly also the attachment member, may be slightly longer than the frame of the roof window. in one embodiment the/each attachment member forms part of a rail member extending over substantially the entire length of a collar member in the length direction, said rail member being plate-shaped having two major
DK 181528 B1 surfaces interconnected by minor surfaces. Such a rail member may be inserted in a groove extending between the frame of the roof window and an insulating frame and arranged such that a first major surface extends along the outer side of the frame and such that the outer portion of the underroof collar 5 extends away from a second major surface, away from the frame.
For ease of installation the inner portion of the underroof collar will typically be attached to the second major surface of the rail member, facing away from the frame of the roof window in the mounted state, but it may also be attached to the first major surface, in which case ft may be brought into close contact with the frame of the roof window during installation. in one embodiment an edge section of the inner portion having a width perpendicular fo the length direction of 10-100 mm, preferably 15-50 mm, is attached to a major surface of the rail member. If attached to the second major surface of the rail member, it may be arranged io extend substantially in parallel 18 fo the outer side of the frame and such that the edge of the inner portion facing away from the outer portion faces away from an interior of a building covered by the roof structure. in this way the underroof collar will extend up along the outer side of the frame, thereby forming a L-shape, which may contribute to deflecting any water being pushed up against the frame of the roof window, for example under the influence of wind. A similar or supplementary effect may be achieved by using a rail member made from a watertight material.
Depending on the design of the attachment member and the material used for the frame of the roof window and the insulating frame, if any, the attachment member may be made from different materials. Particularly the stiffness of the attachment member and the friction between the attachment member and the opening into which it is inserted can be taken into consideration when choosing the material. When using a rail member as attachment member polypropylene (PP) or a thermoplastic elastomer (TPE) may be employed.
As in the prior art, this underroof collar may also comprise at least one side collar member made with a surplus of material to facilitate installation on roof structures comprising laths for supporting a roofing material.
DK 181528 B1 6
A second aspect of the invention relates to a method for sealing the joint between a roof window mounted in a roof structure inclined in a direction of inclination and an underroof of said roof structure, wherein said roof window comprises a frame delimiting a collar opening and having an outer side facing away from the frame opening, and wherein an underroof collar comprises an inner portion, which is configured for extending along the outer side of the frame of the roof window, and an outer portion, which is configured for extending away fram the roof window and for overlapping with sections of an underroof extending along the roof window, said inner portion delimiting a collar opening, and wherein said underroof collar comprises a plurality of collar members each having a length direction extending along the collar opening, said method comprising the steps of: arranging the inner portion of the underroof collar so that the inner portion extends along the outer side of the frame of the roof window, securing the underroof collar in an intended position in relation to the roof window and to the roof structure, wherein the step of securing the underroof collar in the intended position comprises inserting af least one attachment member attached to the inner portion and provided with a barb in an opening at the frame of the roof window.
Embodiments and advantages described with reference to the first aspect of the invention also apply to the second aspect of the invention.

Description of Embodiments
Referring initially to Fig. 1, it is shown how an opening 110 is cut in a roof structure 11 for mounting a roof window. As may be seen, sections of the laths 111 used for supporting the roofing material 112 have been removed, and the underroof 113 has been interrupted by cutting. As shown at the left-hand 18 side of the opening 110, sections 114 of the underroof previously covering the area of the opening 110 are folded over the ends of the laths 111 and the same may be the case with the sections 118 of the underroof extending along the top and bottom of the opening 110. In this case the folded over sections 114 are secured to the laths 111 by means of staples.
A roof window 1 is then mounted in the opening 110 in the roof structure 11 as shown in Fig. 2. in this case an insulating frame 7 surrounds the roof window 1 and mounting brackets & used for securing the frame (not visible in Fig. 2) of the roof window 1 to counter-battens 116 of the roof structure 11 span over the insulating frame 7. The insulating frame 7 may be a separate unit installed in the opening 110 in the roof structure 11 before installation of the roof window 1, or it may be pre-mounted on the frame of the roof window 1 and installed in the roof structure 11 together with the roof window 1.
After mounting of fhe roof window 1, an underroof collar 104 is arranged to surround the roof window 1 as shown in Fig. 3 with an inner portion 1041 extending along the roof window 1 and an outer portion 1042, also referred to as a skirt portion, extending over the roof structure 11.
As shown in Fig. 4, the inner portion 1041 is attached at the frame 2
DK 181528 B1 8 of the roof window 1 by hand, here by inserting an attachment member 1043 in the form of a plate-shaped rail member into a groove 105 between the frame 2 of the roof window 1 and the insulating frame 7.
Turning now fo Figs 5 and 8, details of the installation of an underroof collar 104 are shown. As may be seen, the attachment member 1043, which may be a rail member as in Fig. 4 or a local bracket, is inserted into a groove 105 extending between the frame 2 of the roof window 1 and the insulating frame 7 and substantially in parallel to an outer side 200 of the frame 2.
An edge section 1044 of the inner portion 1041 is attached to the major surface 1045 of the attachment member 1043 facing away from the frame 2 of the roof window 1, so that it extends substantially in parallel to the outer side 200 of the frame 2 in a mounted state and so that an edge 1046 of the inner portion 1041 facing away from the outer portion 1042 faces away from the roof structure 11. in this way the inner portion 1041 has been given an L-shape, which may facilitate diversion of water. Here, the edge section 1044 has a width perpendicular to the length direction L of 16 mm, but it will be understood that it may be smaller or larger depending for example on the construction of the roof window 1 and installation depth in the roof structure 11, and that a similar or supplementary effect may be achieved by using a rail member 1043 made from a watertight material. in the embodiment in Figs 5 and 6, the attachment member 1043 is provided with a barb 1047 and an indentation 75 is provided in the insulating frame 7 matching the size and shape of the barb 1047. The engagement between the barb 1047 and the indentation 75, as shown in Fig. 6, will hinder a retraction of the attachment member 1043 once inserted and will thus contribute to keeping the underroof collar 104 in place, both during and after installation. If the insulating frame 7 is made from an elastic material, the indentation 75 need not be pre-formed as in Fig. 5 but may be made by the barb 1047 during installation. in this embodiment the width of the plate-shaped attachment member 1043 corresponds to the distance from the bottom of the groove or opening 105 to the top of the frame 2, but this need not be the case. While it is considered
DK 181528 B1 9 advantageous for insulating purposes that the groove or opening 105 is not deeper than needed for the insertion of the attachment member 1043, a deeper opening may for example allow the use of several different underroof collars having different attachment members. Likewise, if for example the frame 2 of the roof windows 1 extends in a height above the exterior side of the laths 111, the attachment member may not extend to the top of the frame 2.
To complete the installation of the underroof collar 104, the outer portion 1042 is usually attached to the roof structure 11. This is shown in Fig. 7, where the outer portion 1042 is attached to laths 111 by means of staples.
Components of the roof window 1 and underroof collar 104 are easily disassembled and each component may in principle be reused, be recycled by appropriate environmentally responsible disposal means, or the material be recovered for other uses.
