Thermal break wall systems and thermal adjustable clip

1. An exterior cladding mounting assembly for use in mounting exterior cladding to inner components of a wall, in a wall system, the exterior cladding mounting assembly comprising:

a clip supported between an inner component of a wall and exterior cladding, the clip comprising a spanning web that in use defines a span between the inner component and the exterior cladding; and

a thermal block for interposing between the clip and adjacent components of the wall system, the thermal block comprising:

an insulation material, comprising a fibrous insulation embedded with a silica aerogel;

an encapsulant; and

an adhesive material;

wherein the clip comprises:

two mounting plates, one mounting plate projecting from an edge of the web and the other mounting plate projecting from an opposite edge of the web;

wherein, in use, the thermal block is interposed between one or the other of the mounting plates, and adjacent components of the wall system; and

wherein the mounting plates project from the web in opposite directions, whereby the general configuration of the whole of the clip is a Z shape.

2. The exterior cladding mounting assembly of claim 1 , wherein the clip comprises sheet metal and the projection of each mounting plate from the web is provided by a bend in the sheet metal.

3. The exterior cladding mounting assembly of claim 2 , wherein the sheet metal is galvanized steel or stainless steel.

4. The exterior cladding mounting assembly of claim 1 , wherein each mounting plate has at least one hole for receiving a fastener.

5. The exterior cladding mounting assembly of claim 1 , wherein the web comprises:

a component-tang; and

a component-tang receiver for mating slidable engagement with the tang; and

a fixing means for fixing the tang in a desired position in mating engagement with the tang receiver

wherein, in use the size of the span may be adjusted by selection of the desired position.

6. The exterior cladding mounting assembly of claim 5 , wherein:

the tang is generally planar and has opposed substantially parallel tang edges; and

the tang receiver has opposed substantially parallel channels for receiving the tang edges, to provide the mating slidable engagement with the tang.

7. The exterior cladding mounting assembly of claim 6 , wherein the tang receiver comprises sheet metal and the channels are provided by bends in the sheet metal.

8. The exterior cladding mounting assembly of claim 5 , wherein the fixing means comprises holes in the tang or the tang receiver for use in inserting fasteners through both the tang and the tang receiver to fix one to the other.

9. The exterior cladding mounting assembly of claim 5 , wherein the fixing means comprises aligned holes in the tang and the tang receiver for use in inserting fasteners through both the tang and the tang receiver to fix one to the other in pre-determined relative positions.

10. The exterior cladding mounting assembly of claim 5 , wherein the clip comprises two mounting plates, one mounting plate projecting from an edge of the tang and the other mounting plate projecting from an edge of the tang receiver, each mounting plate having at least one hole for receiving a fastener, wherein, in use, the thermal block is interposed between one or the other of the mounting plates, and adjacent components of the wall system.

11. The exterior cladding mounting assembly of claim 1 , wherein the insulation material is about 10 mm thick or about 20 mm thick.

12. The exterior cladding mounting assembly of claim 1 , wherein the encapsulant comprises a shrink wrap plastic.

13. The exterior cladding mounting assembly of claim 1 , wherein the adhesive comprises a double-sided bonding tape.

14. The exterior cladding mounting assembly of claim 1 , wherein the clip is mounted between the inner component of the wall and exterior cladding.
