Abstract

The invention relates to a building section including a sub-structure and a cladding member connected in fixed relation relative to the sub-structure. A multi-function elongate, flexible insulating element is disposed between the sub-structure and the cladding member for damping energy transfer between the cladding member and the sub-structure, facilitating alignment of the cladding, and creating a rainscreen configured to drive out moisture from the wall cavities. The flexible insulating element includes a bond breaker disposed on the external surface of the insulating element. The bond breaker prevents externally applied joint sealant compound from adhering to the insulating element. The bond breaker can act as a safeguard to prevent joint sealant deterioration or adhesion to undesired surfaces.

Claims

1. A building section comprising:

a sub-structure;

a plurality of cladding members connected in fixed relation relative to the sub-structure, wherein a sealant is disposed between adjacent cladding members; 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 kg/m3 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, wherein an exterior surface of the insulative element comprises a bond breaker, said bond breaker functions as a sealant release and prevents the sealant from adhering to the insulating element;

wherein the at least one substantially incompressible layer of the insulating element has a hardness of at least 60 HD.

2. The building system of claim 1, wherein the insulative element further comprises an adhesive layer.

3. The building system of claim 1, wherein the bond breaker comprises silicone.

4. A building section according to claim 1, wherein the insulating element further comprises two or more layers with a first layer being the at least one substantially incompressible insulating layer and a second layer being more deformable than the substantially incompressible insulating layer so as to readily adapt to irregularities in the cladding and/or building structure.

5. A building section according to claim 1, wherein the at least one substantially incompressible layer of the insulating element has a thermal conductivity of less than 0.1 W/m·

K.

6. A building section according to claim 1, wherein the thickness of the insulating element is in the range of about 5 mm to 50 mm.

7. A building section according to claim 1, wherein the insulating element has a plurality of markings, the markings being spaced relative to one another on an outer surface of the insulating element for facilitating alignment of the cladding members relative to the sub-structure.

8. A building section according to claim 1, wherein the sub-structure includes an intermediate support member connected to a frame member, the support member being arranged intermediate the frame member and the cladding member such that the insulating element is sandwiched between the frame member and the support member or between the support member and the cladding member.

9. A building section comprising:

a sub-structure;

a plurality of cladding members connected in fixed relation relative to the sub-structure, wherein a sealant is disposed between adjacent cladding members; 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 kg/m3 to 300 keg 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, wherein an exterior surface of the insulative element comprises a bond breaker, said bond breaker functions as a sealant release and prevents the sealant from adhering to the insulating element;

wherein the at least one substantially incompressible layer of the insulating element has a compressive strength in the range of approximately 200 kPa to 400 kPa.
