FIELD OF THE INVENTION
[0001] The present invention relates generally to the field of building systems and, in particular. to systems incorporating the use of improved materials for insulating a section of a building.
[0002] The invention has been developed specifically for use in connection with internal and external cladding systems and will be described primarily with reference to this application.
BACKGROUND TO THE INVENTION
BACKGROUND TO THE INVENTION
[0003] The following discussion of the prior art is intended to enable the invention to be placed in an appropriate technical context and to allow the advantages of it to be fully appreciated. However, any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely- known or forms part of common general knowledge, in the field.
(0004] With the advent of new and improved cladding materials in a variety of geometrical fours, the popularity of frame plus cladding construction techniques is increasing, particularly. in the residential market. At the same time there is increasing demand for energy efficient structures which necessitates, or at least encourages, use of insulating materials between the frame and the cladding of such structures.
[0005] One difficulty which arises in constructing some cladding systems, is the need to correctly align the mating surfaces of adjacent cladding panels on the frame, and to maintain this alignment after the erection process has been completed.
In a cladding system for a wall, it is typically desired to fix the cladding panels to the frame such that a substantially-continuous wall surface is defined by each array of panels, be they flat mounted panels or long arrays of panels to be mounted in an overlapping arrangement. However, using popular soft foam thermal Insulating strips for example, it is often difficult to achieve such a flat surface at the adjoining or abutting edges of adjacent panels, which reduces the aesthetic appeal provided by the final wall. This difficulty arises, at least in part, due to the physical properties of these soft foam insulating strips and/or irregularities in the frame.

[0006] Such misalignment of adjacent cladding panels can give rise to a more serious situation where the building section Is a floor of the building. In particular, such misalignment of adjacent panels or floor boards can give rise to undesirable unevenness in flooring. While rigid polystyrene foam alternatives used for waft and high density rubber sheets used for floors reduce this problem to some extent, they are slow to install and awkward to transport.
[0007] Another issue which arises with the use of soft foam strips is that,.
when either hand or gun nailing the cladding panels to the frame, the nails. are often over driven such that an indentation is formed in the cladding panel and the head of the nail sits beneath the surface of the panel, again reducing the aesthetic appeal provided by the wall.

[0008] It is an object of the present invention to overcome or ameliorate one or more of the disadvantages of the prior art, or to at least provide a useful alternative.
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[0009] According to a first aspect of the Invention, there is provided a building section including:
a sub-structure;
a cladding member connected in fixed relation relative to the sub-structure;
and an elongate, flexible insulating element, the insulating element having at least one insulating layer which is substantially Incompressible and which has a substantially constant density in the range of 200 kgfrn3 to 300 kg/m3, wherein the insulating element is disposed between the sub-structure and the cladding member for damping energy transfer between the cladding member and the sub-structure.
a sub-structure;
a cladding member connected in fixed relation relative to the sub-structure;
and an elongate, flexible insulating element, the insulating element having at least one insulating layer which is substantially Incompressible and which has a substantially constant density in the range of 200 kgfrn3 to 300 kg/m3, wherein the insulating element is disposed between the sub-structure and the cladding member for damping energy transfer between the cladding member and the sub-structure.
[0010] The term "substantially incompressible" is used herein to define at least one insulating layer of an insulating element which substantially resists compression during and after fixing between a sub-structure and a cladding memberwhen conventional fasteners are used to secure the cladding member to the sub-structure with the insulating element therebetween.
[0011] The term "cladding member" is intended to include all internal or external wall, floor and ceiling covering panels and planks or opening covers such as windows and door frames, as may be secured to a structural frame to define a.building envelope.
AMENDED SHEET
IPEA/AU
Received 07/12/2011 (00121 The substantially incompressible characteristic of the at least one insulating layer results in this layer substantially maintaining its geometric shape when the cladding member is being connected to the sub-structure by fasteners which pass through the insulating element. Desirably, the at least one insulating layer provides support to the cladding member when the cladding member is being secured to the sub-structure. It will be appreciated that this enables cladding materials such as fibre cement panels to be nailed or screwed to the sub-structure using conventional power tools and the like by providing rear support to the material. Advantageously, the substantial incompressibility of the at least one insulating layer helps facilitate the erection of a building section having a substantially continuous cladding surface at the abutting edges of adjacent cladding members. The substantial incompressibility of the at least one insulating layer also helps to inhibit over driving fasteners when using conventional hand and power tools.
[0013] In certain preferred embodiments, the insulating element reduces the transfer of thermal energy between the cladding member and the sub-structure.
In other preferred embodiments, the insulating element reduces the transfer of acoustic energy between the cladding member and the substructure. Preferably, the insulating element reduces the transfer of both thermal and acoustic energy between the cladding member and the sub-structure. In some embodiments, the damping of energy transfer between the cladding member and the substructure is primarily effected by the at least one substantially Incompressible insulating layer. In other embodiments, the damping of energy transfer is achieved by the combination of the substantially incompressible insulating layer or layers and the remaining layer or layers of the insulating element.
That is, in these embodiments, the damping of energy transfer is achieved by the insulating element as a whole.
100141 The cladding member is preferably connected to the sub-structure via one or more fasteners. Preferably, the one or more fasteners securely engage the sub-structure and the cladding member. At least certain of the one or more fasteners preferably pass through the insulating element to hold the insulating element in a desired position relative to the cladding member/sub-structure. The fasteners are preferably selected from the group including nails, screws, staples and rivets. However, it will be appreciated by those skilled in the art that the fasteners are not limited to those listed here, and that any suitable fastener (including adhesives) may be used to connect the cladding member to the sub-structure.

Received 07/12/2011 [00151 The at least one insulating layer is preferably formed of a foam, more preferably, a closed cell foam such as, for example, polyolefin. In some preferred forms, the foam is cross-linked. Suitable cross-linked foams include polyurethane and polystyrene. I will of course be appreciated that the closed cell and cross-linked foams are not limited to those listed here. and that other suitable foams may be used.
[0016] In addition, it will also be appreciated that the insulating element may, in certain preferred forms, be a homogeneous element such that the overall construction results in a flexible, substantially incompressible insulating element [00171 However, in other preferred embodiments, the insulating element may be a hybrid or composite element having two or more layers, at least one layer being formed of a material having at least one different physical property relative to the material used to form one or more of the other layers. For example, the insulating element may be a two-layer element having one layer which is relatively 'harder' than the other- Alternatively, the Insulating element may be a three-layer element in which the outer layers are relatively 'harder' than the inner layer, or vice versa.
In such embodiments, the first 'harder' layer or layers are substantially incompressible and the second 'softer' layer or layers can advantageously deform to account for, or at least reduce the effect of, irregularities in the sub-structure to provide a substantially flat surface across adjacent cladding panels. Accordingly, in embodiments having a 'softer' outer layer, this layer preferably abuts the sub-structure. However, in other embodiments the softer outer layer could abut the cladding member or another intermediate member.
[00181 It will of course be appreciated that the Insulating element could be embodied in many various di ferently layered constructions to suit a particular building application.
[0019] For multi-layered embodiments of the insulating element, one or more of the physical properties of density, hardness, compressive strength, thermal conductivity, thermal resistance, cross-section and thickness of at least one layer may be configured to be different to. that of another layer of the insulating element. it will be appreciated by those skilled in the art that the physical properties which can be varied are not limited to those listed here-AMENDED SHEET

[0027] Preferably, the insulating element (orthe at least one insulating layer) has a thermal conductivity of less than 0.1 WIm=K.

Received 07/12/2011 (00121 The substantially incompressible characteristic of the at least one insulating layer results in this layer substantially maintaining its geometric shape when the cladding member is being connected to the sub-structure by fasteners which pass through the insulating element. Desirably, the at least one insulating layer provides support to the cladding member when the cladding member is being secured to the sub-structure. It will be appreciated that this enables cladding materials such as fibre cement panels to be nailed or screwed to the sub-structure using conventional power tools and the like by providing rear support to the material. Advantageously, the substantial incompressibility of the at least one insulating layer helps facilitate the erection of a building section having a substantially continuous cladding surface at the abutting edges of adjacent cladding members. The substantial incompressibility of the at least one insulating layer also helps to inhibit over driving fasteners when using conventional hand and power tools.
[0013] In certain preferred embodiments, the insulating element reduces the transfer of thermal energy between the cladding member and the sub-structure.
In other preferred embodiments, the insulating element reduces the transfer of acoustic energy between the cladding member and the substructure. Preferably, the insulating element reduces the transfer of both thermal and acoustic energy between the cladding member and the sub-structure. In some embodiments, the damping of energy transfer between the cladding member and the substructure is primarily effected by the at least one substantially Incompressible insulating layer. In other embodiments, the damping of energy transfer is achieved by the combination of the substantially incompressible insulating layer or layers and the remaining layer or layers of the insulating element.
That is, in these embodiments, the damping of energy transfer is achieved by the insulating element as a whole.

However, those skilled in the art will appreciate that the frame 2 may be a section of any suitable building frame including a wall frame, a sub-floor frame, a ceiling frame and a roof frame. It will be further appreciated by those skilled in the art that the present invention is not limited to the sub-structures listed here.
In addition, it Is to be understood that certain frames may be inclined, rather than being arranged to lie in a substantially vertical or horizontal plane.
[0058] As most clearly shown in FIG. 1, a plurality of cladding=members in the form of fibre cement cladding panels 4 are connected in fixed relation relative to the frame 2 by fasteners 5. As will be described in greater detail below, the plurality of cladding panels 4 form a cladding or wall surface 6 for the building section 1. To facilitate connection of the panels 4 to the frame 2 of the wall section, each cladding panel 4 preferably spans two or more of the frame members 3.
[0057] The type of fasteners 5 used to secure the panels 4 to the frame 2 will be primarily determined by the type of material of the frame members 3. That is, fasteners in the form of screws,, nails or staples can be used to securely fasten the cladding panels 4 to a timber frame. However, to fasten the panels 4 to a metal frame, it may be necessary to employ screws or rivets.

-13-(00601 The insulating foam tape 7 is applied in strips and positioned to extend in a direction substantially parallel to the longitudinal axis of the associated frame member 3. In the embodiment illustrated in FIG. 2, a strip of foam tape 7 is applied to each vertical frame member 3. However, it will be appreciated that in certain embodiments, it may be sufficient to apply strips of foam tape 7 to only a selected few of the vertical frame members 3. In yet further embodiments such as that shown in FIG. 4, a strip of foam tape 7 can be applied to each vertical and horizontal frame member 3.
[0061] As most clearly shown in FIG_ 2, the foam tape 7 has a rectangular cross-section with a constant thickness along the length of the strip. The insulating foam tape7 defines a mounting surface B on which an attaching means In the form of a layer of acrylic adhesive 9 is applied, The adhesive 9 enables the foam tape 7 to be readily adhered to the relevant frame member 3 in the desired position. It will therefore be appreciated that the adhesive layer 9 provides the foam tape 7 with the characteristic of a self-adhesive tape. In some embodiments, a removable backing strip (not shown) covers the mounting surface 8 to protect the layer of adhesive 9 from dust and other debris during storage of the foam tape 7 prior to use.
[00621 The insulating tape 7 is preferably formed of a closed cell, cross-linked foam such as, for example, polyolefin. The insulating element is substantially incompressible such that the Insulating element substantially maintains its geometric shape when the cladding member is being fastened to the frame. This property enables the insulating element to provide support to the cladding material when the cladding member is being secured to the sub-structure.
[00831 It will be appreciated that it is this property of substantially incompressibility which enables relatively brittle cladding materials to be nailed or screwed to the frame 2 using power tools and the like. For example, a nail-gun can conveniently be employed to efficiently fasten the panels 4 to the frame 2, without significant variations in the level or degree of compression of the foam tape 7 at the various locations at which the fasteners have been placed.
[0064] The significant lack of compression of the foam tape 7 in combination with the degree to which this compression is consistent at the various fastening locations is particularly advantageous at the adjoininglabutting. edges of adjacent cladding panels 4. That is, the substantial incompressibility of the foam tape AMENDED SHEET
Received 07/12/2011 facilitates the erection of a building section 1 having a substantially flush wall surface 6 at the abutting edges of adjacent cladding panels. In other words, the adjoining or abutting edges are not significantly raised or lowered relative to each other as a result of the fastening process. To achieve the required degree of incompressibility, the polyolefrn preferably has a substantially constant density of about 230 kg/rre 10%.
[00651 In the form shown in the drawings, the width of the foam tape 7 is less than that of the associated frame member to which it Is attached. In the illustrated embodiments, the width of the foam tape 7 is approximately 45mm. The thickness of the foam tape Is approximately 13mm 0.16mm. it will be appreciated that the tape may be formed in various widths with the thickness of the tape then being selected to provide the Insulating tape with a thermal resistance of at least 0.2 K.m2MW
(or a thermal conductivity of <0.06W/m=K)..
[0066] Each strip of foam tape 7 is adhered directly to the respective frame member 3 by the layer of adhesive 9. A fibre cement cladding panel 4 is then held in position relative to the frame 2, against the foam tape 7. The panel 4 Is then secured in the desired position such that each strip of foam tape 7 is disposed between the frame 2 and the associated panel 4. As clearly shown in FIG. 2, at least some of the fasteners pass through the foam tape 7. The adhesive 9 works in combination with these fasteners to securely hold the strip of foam tape 7 relative to the cladding member 4 and frame 2.
[0067] In the cladded wall section 1 shown in the drawings, the foam tape 7 forms a thermal breakfor damping thermal transfer between the cladding panels 4 and the frame 2 to reduce thermal losses through the wall section 1.
(00681 It will be appreciated that in those embodiments in which the frame is a roof or ceiling frame, the Insulating element again primarily provides thermal insulation.
However, in those embodiments in which the frame is a sub-floor frame, the insulating element primarily provides acoustic insulation. In certain applications, including those listed above, the foam tape can provide both thermal and acoustic insulation for the building section 1 and therefore reduce energy losses. It will be further appreciated that the foam tape 7 may also provide a degree of moisture management for the building section.

[0061] As most clearly shown in FIG_ 2, the foam tape 7 has a rectangular cross-section with a constant thickness along the length of the strip. The insulating foam tape7 defines a mounting surface B on which an attaching means In the form of a layer of acrylic adhesive 9 is applied, The adhesive 9 enables the foam tape 7 to be readily adhered to the relevant frame member 3 in the desired position. It will therefore be appreciated that the adhesive layer 9 provides the foam tape 7 with the characteristic of a self-adhesive tape. In some embodiments, a removable backing strip (not shown) covers the mounting surface 8 to protect the layer of adhesive 9 from dust and other debris during storage of the foam tape 7 prior to use.
[00621 The insulating tape 7 is preferably formed of a closed cell, cross-linked foam such as, for example, polyolefin. The insulating element is substantially incompressible such that the Insulating element substantially maintains its geometric shape when the cladding member is being fastened to the frame. This property enables the insulating element to provide support to the cladding material when the cladding member is being secured to the sub-structure.
[00831 It will be appreciated that it is this property of substantially incompressibility which enables relatively brittle cladding materials to be nailed or screwed to the frame 2 using power tools and the like. For example, a nail-gun can conveniently be employed to efficiently fasten the panels 4 to the frame 2, without significant variations in the level or degree of compression of the foam tape 7 at the various locations at which the fasteners have been placed.
[0064] The significant lack of compression of the foam tape 7 in combination with the degree to which this compression is consistent at the various fastening locations is particularly advantageous at the adjoininglabutting. edges of adjacent cladding panels 4. That is, the substantial incompressibility of the foam tape AMENDED SHEET
Received 07/12/2011 facilitates the erection of a building section 1 having a substantially flush wall surface 6 at the abutting edges of adjacent cladding panels. In other words, the adjoining or abutting edges are not significantly raised or lowered relative to each other as a result of the fastening process. To achieve the required degree of incompressibility, the polyolefrn preferably has a substantially constant density of about 230 kg/rre 10%.
[00651 In the form shown in the drawings, the width of the foam tape 7 is less than that of the associated frame member to which it Is attached. In the illustrated embodiments, the width of the foam tape 7 is approximately 45mm. The thickness of the foam tape Is approximately 13mm 0.16mm. it will be appreciated that the tape may be formed in various widths with the thickness of the tape then being selected to provide the Insulating tape with a thermal resistance of at least 0.2 K.m2MW
(or a thermal conductivity of <0.06W/m=K)..
[0066] Each strip of foam tape 7 is adhered directly to the respective frame member 3 by the layer of adhesive 9. A fibre cement cladding panel 4 is then held in position relative to the frame 2, against the foam tape 7. The panel 4 Is then secured in the desired position such that each strip of foam tape 7 is disposed between the frame 2 and the associated panel 4. As clearly shown in FIG. 2, at least some of the fasteners pass through the foam tape 7. The adhesive 9 works in combination with these fasteners to securely hold the strip of foam tape 7 relative to the cladding member 4 and frame 2.
[0067] In the cladded wall section 1 shown in the drawings, the foam tape 7 forms a thermal breakfor damping thermal transfer between the cladding panels 4 and the frame 2 to reduce thermal losses through the wall section 1.
(00681 It will be appreciated that in those embodiments in which the frame is a roof or ceiling frame, the Insulating element again primarily provides thermal insulation.
However, in those embodiments in which the frame is a sub-floor frame, the insulating element primarily provides acoustic insulation. In certain applications, including those listed above, the foam tape can provide both thermal and acoustic insulation for the building section 1 and therefore reduce energy losses. It will be further appreciated that the foam tape 7 may also provide a degree of moisture management for the building section.
