Abstract

A method comprises: providing a fiber cement substrate, and joining a porous, closed cell foam to a substantial portion of a major surface of the fiber cement substrate.

Claims

1. A method comprising:

providing a fiber cement substrate; and

joining a porous, closed cell foam to a substantial portion of a major surface of the fiber cement substrate.

2. The method of claim 1, wherein the substrate is shaped as a section of siding, a shake, a soffit, roofing tile or shingle, a panel, or a trim piece.

3. The method of claim 1, wherein:

the substrate is shaped as a section of siding, a shingle or a shake; and

the joining step includes covering a surface of the siding, shingle or shake with the foam, except in a region where the section of siding, shingle or shake is to overlap a neighboring section of siding, shingle or shake.

4. The method of claim 1, wherein:

the substrate is shaped as a section of siding, a shingle or a shake; and

the bonding step includes covering a major surface of the siding, shingle or shake with the foam, except in a relatively narrow region adjacent to a first edge of the substrate.

5. The method of claim 4, wherein the foam is tapered from a relatively large thickness adjacent the narrow region to a relatively small or zero thickness at a second edge opposite the first edge.

6. The method of claim 1, wherein:

the substrate is a soffit or a panel; and

the bonding step includes covering an entire rear major surface of the soffit or panel.

7. The method of claim 1, wherein the foam is made of polypropylene or polyethylene.

8. The method of claim 1, wherein the joining step comprises:

providing the foam in the form of a sheet; and

bonding the foam to the substrate with an adhesive.

9. The method of claim 1, wherein the foam is bonded to the substrate without an adhesive therebetween.

10. The method of claim 9, wherein the foam is attached to the substrate by mechanical fastening.

11. The method of claim 10, wherein the foam is attached to the substrate using staples, flanges or prongs

12. The method of claim 9, wherein the foam is attached to the substrate by fusing, or forming the foam on the substrate.

13. The method of claim 12, wherein the bonding step includes pouring the foam onto the substrate, and allowing the foam to solidify.

14. The method of claim 1, wherein the foam comprises polyurethane.

15. A method comprising:

providing a unitary panel, section of siding, roofing tile or shingle, shake, soffit or trim piece including a fiber cement substrate and a porous, closed cell foam bonded to a substantial portion of a major surface of the fiber cement substrate; and

mounting the panel, section of siding, roofing tile or shingle, shake, soffit or trim piece on a building surface.

16. The method of claim 15, further comprising permitting moisture to drain from between the substrate and the building surface by way of interstices between cells of the foam.

17. The method of claim 15, wherein the foam is tapered from a relatively large thickness adjacent a narrow region along a first edge of the substrate to a relatively small or zero thickness at a second edge of the substrate opposite the first edge, the method further comprising:

overlapping a second section of siding, shingle or shake with the first section of siding, shingle or shake, so that a rear surface of the foam on each of the first and second sections of siding, shingles or shakes contacts the building surface.

18. The method of claim 15, wherein the foam covers a major surface of the siding, shingle or shake, except in a region where the section of siding, shingle or shake is to overlap a neighboring section of siding, shingle or shake.

19. The method of claim 18, wherein the mounting step includes:

positioning the section of siding, shingle or shake so that a major surface of the foam contacts the building surface and acts as a spacer to position the region of the section of siding, shingle or shake at a non-zero distance from the building surface.

20. The method of claim 18, wherein the mounting step includes:

positioning the section of siding, shingle or shake so that a major surface of the foam faces away from the building surface and acts as a spacer to position a bottom portion of an adjacent second section of siding, shingle or shake at a non-zero distance from the building surface.

21. The method of claim 15, wherein:

the foam covers a rear surface of the siding, shingle or shake, except in a region where the section of siding, shingle or shake is to overlap a neighboring section of siding, shingle or shake, and the mounting step includes;

positioning the section of siding, shingle or shake so that a bottom edge of the foam rests on a top edge of an adjacent section of siding, shingle or shake.

22. A method comprising:

providing a fiber cement substrate;

forming a plurality of grooves in a surface of a layer of closed cell foam; and

joining the closed cell foam to a substantial portion of a major surface of the fiber cement substrate.

23. The method of claim 22, wherein the substrate is shaped as a section of siding, a shake, a soffit, roofing tile or shingle, a panel, or a trim piece.

24. The method of claim 23, wherein the grooves are oriented so that they have a direction with a substantial vertical component when the siding, shake, soffit, roofing tile or shingle, panel, or trim piece is installed.

25. The method of claim 22, wherein the grooves are located on the major surface of the foam facing away from the fiber cement substrate.
