Definitions

  • the present invention relates to an insulating frame for a roof window mounted in an inclined roof structure of a building, comprising top, bottom and side frame members, each including an insulating member and a support member, and a plurality of connector brackets, said insulating frame defining an inner opening adapted to surround a frame of the roof window and said insulating frame having an interior side intended to face the interior of the building and an exterior side intended to face the exterior and each frame member having an inner side facing the inner opening and an outer side facing away from the inner opening, said insulating frame further defining a base plane at the interior side of the insulating frame members which is substantially parallel with the inner opening.
  • Such insulating frames have found wide use and considerably improved the insulating properties of inclined roofs with roof windows, as well as the ease with which a window may be installed in an inclined roof structure.
  • EP2677092A1 flanges on the support members are used for connecting the insulating frame to the roof structure and since they extend over substantially the entire length of the insulating frame members this insulating frame can easily be connected to virtually any roof structure.
  • the insulating frame is simply inserted in the pre-made opening in the roof structure and the flanges on the support member will then automatically come into abutment with portions of the roof structure, such as battens, to which they may be attached.
  • an insulating frame as described above, where the insulating frame comprises a set of roof connector brackets adapted for connecting the insulating frame to the roof structure and at least one attachment section on an insulating member or a support member, wherein each of the roof connector brackets comprises a first connecting section and a second connecting section, where the first connecting section is connected to an attachment section in the assembled state of the insulating frame, and where the second connecting section is adapted for connecting to the roof structure and extends away from the inner opening of the insulating frame in the assembled state in parallel with the base plane and beyond the outer side of the frame member to which the roof connector bracket is attached, and where said attachment section(s) allow attachment of each roof connector bracket at several different positions depending on the design of the roof structure.
  • roof connector brackets can be attached at the positions fitting the design of the specific roof structure in which it is to be used, thus providing high versatility with a minimum material consumption.
  • top, bottom and side are used to indicate the intended position of different parts in the mounted position even though these parts may be located differently during for example storage and transportation or prior to assembly of the insulating frame.
  • internal and exitterior are used to indicate that something is intended to face the interior or exterior of the building in which the roof window is mounted, respectively, and the terms “inner” and “outer” that something is intended for facing towards or away from the inner opening of the insulating frame, respectively, in the mounted state.
  • the roof connector brackets having a first connecting section adapted for connecting to the at least one attachment section may have the effect of improving handling and transportation as the connector brackets and the insulating frame members may be provided separately so that the insulating frame can be assembled in-situ.
  • One or more of the roof connector brackets may be adapted for displaceable attachment to the attachment section such that the one or more connector brackets may be moved along the length direction of the attachment section after being attached. This may have the effect of improving the ease of installation of the roof window as the position of the roof connector brackets may be adjusted once mounted e.g. by moving one or more roof connector brackets to a desired position e.g. a position where the roof connector bracket is located over a batten of the roof structure and may be connected thereto. This has the further effect that the risk of roof connector brackets being lost or forgotten is reduced compared to embodiments where they are to be attached by the installer.
  • lactable attachment may be understood as being able to be moved along an attachment section in the length direction of an insulating frame member after being attached, without substantially damaging the connector brackets and/or attachment section and/or support member and/or insulating member and/or frame member and/or insulating frame e.g. by pushing or pulling the connector bracket.
  • the roof connector brackets as such may be of different shapes, lengths, widths and/or heights.
  • the first connecting sections and/or second connecting sections of the roof connector brackets may be of different shapes lengths, widths and/or heights. This may have the effect that it allows the insulating frame to be adapted to a given roof structure by using the appropriate types of roof connector brackets.
  • the roof connector brackets may be made of wood, steel, stainless steel, aluminium, other metals, polymers, ceramics, glass fibre, composites and/or combinations thereof.
  • the roof connector brackets may comprise a support section.
  • the support section may engage with the attachment section and/or support member and/or insulating member and/or insulating frame member. This may have the effect of improving the connection between the roof connector bracket and the insulating frame member and thus improving the strength and stability of the insulating frame.
  • the support section may be in the form of a plate that is pressed into engagement.
  • the attachment section may be a separate element or be an integrated part of an insulating member or a support member.
  • the attachment section may be made from a material different from the insulating and/or support member. This may have the effect that materials of the different components of the insulating frame may be optimised to the specific purpose such as thermal properties, strength, cost and/or ease of manufacture.
  • the attachment section may comprise interconnecting means for interconnecting with roof connector brackets.
  • the interconnecting means may be in the form of channels or grooves adapted for engaging with first connecting sections of the roof connector brackets.
  • the interconnecting means may be in the form of rivets, screws, nails, spikes, or the like.
  • the interconnecting means may for example engage by snap-locking, barbed sections, and/or press fitting.
  • a barbed section can include lugs, pins or other protrusions looking like semi-pierced fingernail detent formed into the connector bracket or guide member e.g. by punching or stamping.
  • the barbed section may facilitate snap-locking.
  • space-locking may be understood as the connector bracket mechanically fastening itself to the attachment section once it is brought into the correct position.
  • the length of the attachment section may be of substantially the same length as the insulating frame member and/or insulating member and/or support member.
  • the length of the attachment section and/or the support member may be less than 3/4, 1/2, 1/3, 1/4, or 1/5 of the length of an insulating frame member.
  • the insulating frame member may also comprise several attachment sections.
  • the attachment section being of substantially the same length as the insulating frame member may improve the ease of installation of the insulating frame as the connector bracket may then be placed at virtually any desired location on the attachment section e.g. at a location where the connector bracket will be proximal to a batten of the roof structure such that it may be connected thereto.
  • the attachment section may be a separate part of the insulating frame. This may have the effect that the attachment section may be selectively arranged at a desired location, such as near the battens of the roof structure. This may also have the effect that the insulating frame may be tailored to a certain roof structure by varying the number and location of the at least one attachment section.
  • the attachment section may be a different material to the rest of the insulating frame member.
  • the attachment section may be a high density foam where the insulating member is a low density foam.
  • the attachment section is located at an exterior side of an insulating frame member. This may have the advantage that it improves the ease with which roof connector brackets may be attached to the attachment section, thus improving the ease of installation of the insulating frame.
  • the attachment section is made from a material chosen from the following group: wood, metal, polymer, high rigidity polymer foam such as EPS (expanded polystyrene) or combinations thereof, where the material may comprise perforations.
  • EPS expanded polystyrene
  • the attachment section may be made from the same material as the support member and vice versa.
  • the support member is made from a rigid insulating material, such as a non-elastic foamed polymer.
  • the attachment section may then be a part of the support member.
  • the attachment sections may be adapted to interconnect with one or more other attachment sections, for example via a mortise joint or the like. In this way, it is for example possible to establish a continuous series of attachment sections extending along the entire insulating frame, and it is of course also possible to provide one continuous attachment section extending all the way around the insulating frame.
  • the first connecting section of the roof connector brackets is adapted for detachable attachment.
  • attachment may be understood as being able to be removed by non-destructive mechanical action where neither the insulating frame, attachment section or connector bracket is substantially damaged and the connector bracket is able to be reattached to the attachment section. For example, by pulling the connector bracket off.
  • the roof connector brackets being detachable may have the effect of improving the ease of installation of the insulating frame as a wrongly placed roof connector bracket may be detached and reattached at the required location. It may also improve the ease of transportation of the insulating frame as the roof connector brackets may be transported, packaged and/or shipped pre-attached to the insulating frame in a position optimal for packaging and transportation and then moved during installation. It may also improve maintenance, should it be required, as a potentially damaged roof connector bracket may simply be removed and replaced. It may also provide a greater flexibility of installation as the insulating frame may be adapted to different installation scenarios by varying the number and/or types of roof connector brackets used in-situ.
  • the first connecting section extends over half or less than half the length of an insulating frame member.
  • the first connecting section of the roof connector brackets are adapted for attachment via snap-locking.
  • the first connecting sections may alternatively be adapted for being attached to the attachment section by screws, bolts, spikes or the like.
  • the first connection section may comprise a tab for releasing the roof connector bracket from the attachment section.
  • the first connecting section may comprise interconnecting means in the form of a barbed section.
  • the barbed section can include lugs, pins or other protrusions looking like semi-pierced fingernail detent formed into the connector bracket or guide member e.g. by punching or stamping.
  • the barbed section may facilitate snap-locking.
  • the second connecting section of the roof connector brackets comprises means for attachment to a roof structure such as holes for screws, spikes, nails and the like.
  • the second connecting section may be in the form of one or more flanges extending over at least a part of the length of the roof connector bracket and projecting from the frame away from the opening in the mounted state.
  • the flange may comprise a series of holes and/or recesses and/or openings adapted for allowing a screw, nail, rivet or spike to pass through for securing the connector bracket to a roof structure.
  • the insulating frame is provided as a kit for making an insulating frame according to one or more embodiments of the first aspect of the invention, comprising a plurality of insulating frame members and a plurality of roof connector brackets.
  • roof connector brackets first to the insulating frame member(s) and then to the roof structure, while other roof connector brackets used for installing the same insulating frame are connected first to the roof structure and then to the insulating frame member(s).
  • roof connector brackets at one side of the insulating frame may be connected first to the corresponding side insulating frame member while roof connector brackets at the opposite side of the insulating frame are connected first to the roof structure, so that the insulating frame can be swung into place in the opening in the roof structure.
  • An insulating frame 100 will now be described in reference to Fig. 1 .
  • An insulating frame 100 like this is typically installed in a suitable opening in a roof structure (not shown).
  • the insulating frame provides an insulating barrier at the interface between a roof window (not shown) and the roof structure, and facilitates easier mounting of the roof window by providing a predefined space adapted for the window.
  • the frame 100 can be delivered as a complete kit for assembly including a plurality of insulating members 112, a plurality of support members 114 and a plurality of roof connector brackets 200, providing a convenient solution for the installer.

  • the insulating frame 100 comprises top 110c, bottom 110d and side insulating frame members 110a and 110b, which refer to their location when mounted, support members and a plurality of connector brackets 200 as will be discussed in more detail below.
  • the insulating frame members 110a-110d define an inner opening 3.
  • the insulating frame members comprise a ledge 120 projecting towards the inner opening 3, which is intended to project underneath a frame of a roof window, which the insulating frame 100 is intended to receive.
  • the outer side of the insulating frame 100 is intended to face the opening in the roof structure.
  • the insulating members 112 which make up the majority of the volume of the insulating frame 100, are made from a material of a dimensionally stable nature having good thermal insulating properties.
  • the insulating members of the side insulating frame members 110a, 110b further comprise a softer material on the outer side, which is compressible so as to allow it to yield and adapt to the shape of the opening in the roof structure. Further details of this are described in the applicants granted patent EP2677092B1 .
  • the insulating members of the side insulating frame members 110a, 110b are made from two types of polymer foam. It is, however, also possible to make them from a single material, and/or for the insulating members of the top and bottom insulating frame members 110c, 110d to be made from different materials or combinations of materials.
  • roof connector brackets 200a and 200b which may be collectively referred with reference number 200
  • the connector brackets 200 are attached to the attachment sections 500 of the insulating frame members 110d and 110a via their respective first connection sections 220 best seen in Fig. 4 .
  • the insulating frame 100 need not be attached to battens (not shown) or other parts of the roof structure, but may simply rest on top of these as the subsequent fastening of the roof window will also secure the insulating frame 100.
  • holes 213, which allow a clamp, nail, spike or screw to pass, are provided in the second connecting sections 210.
  • the features here described in relation to the bottom insulating frame member 110d and one of the side insulating frame member 110a also apply to the other side insulating frame member 110b and the top insulating frame member 110d, which are substantially the same.
  • the first type of roof connector bracket 200a used at the corners is an angular L shaped bracket having two legs, where each leg comprises a first connecting section 220, a second connecting section 210 and a support section 250 best seen in Fig. 4 .
  • the angular L shape allows the roof connector bracket 200a to be attached to two insulating frame members 110 such as shown in Fig. 1 .
  • This roof connector bracket 200a also acts as a corner or frame connector bracket interconnecting the two insulating frame members with the additional advantages of the second connecting section 210 of a roof connector bracket 200.
  • the first connecting section 220 of each leg of the roof connector bracket 200a comprises interconnecting means in the form of a barbed section, as shown in Fig. 4 , which engage with the interconnecting means 130 (see Fig. 3 ) of attachment sections 500.
