Abstract

A foam wall structure includes a frame, at least one primary support member, a slab of polyiso board and a foam layer. The frame can include: a first member; a second member spaced apart from the first member; and two side members extending between the first and second members. The frame defining a front frame surface and an opposite rear frame surface. The at least one primary support member can be positioned between the two side members and extend between the first and second member. The primary support member defines a front support surface and an opposite rear support surface. The slab of polyiso board may be attached to the front frame surface. The foam layer can be received within at least a portion of the frame and overlies the front surface of the primary support member. A method of making a foam wall structure and a pre-fabricated wall is also disclosed.

First claim

What is claimed is:

1. A foam wall structure comprising:
a) a frame comprising:
a first member;
a second member spaced apart from the first member; and
two side members extending between the first and second members, wherein the first member, second member, and two side members each have a front surface and a rear surface that form the front frame surface and the rear frame surface of the frame;

b) at least one primary support member positioned between the two side members and extending between the first and second member, wherein the primary support member defines a front primary support surface and an opposite rear primary support surface corresponding to the front frame surface and rear frame surface;
c) foam insulation positioned over the front frame surface, the foam insulation positioned over the front frame surface consisting of polyiso board having a front face and a rear face, and a facer material attached to at least a portion of at least one of the front face and the rear face, wherein the polyiso board is attached to and in contact with one of at least a portion of the front frame surface or at least a portion of the front primary support surface, such that the polyiso board, the first and second members, the two side members and the at least one primary support members define one or more voids within the frame; and
d) a foam layer received within at least a portion of one of the voids within the frame, wherein the foam layer adheres to at least a portion of the polyiso board,
wherein the foam layer is dimensioned to a position intermediate the front frame surface and rear frame surface such that a gap is formed within the frame between the foam layer and the rear frame surface, and
wherein the polyiso board has a thickness of about ½″ to about 3″.

2. The foam wall structure of claim 1 , wherein the facer material comprises an impermeable foil.

3. The foam wall structure of claim 1 , wherein the foam layer does not overlie the front frame surface.

4. The foam wall structure of claim 1 , wherein the polyiso board is attached to the at least a portion of the front face of the first and second members and the two side members by fasteners.

5. The foam wall structure of claim 1 , wherein the polyiso board is attached to at least a portion of the front face of the first and second members and the two side members by one or more adhesives.

6. The foam wall structure of claim 1 , wherein the frame further comprises one or more secondary support members extending between two adjacent primary support members or a primary support member and a side member such that a secondary opening is formed within the frame, and wherein the secondary opening is free of foam, and a corresponding opening is present in the polyiso board.

7. The foam wall structure of claim 6 , wherein the frame further comprises one or more tertiary support members extending between two secondary support members, or between a secondary support member and the first member or the second member.

8. The foam wall structure of claim 1 , wherein the foam layer comprises polyurethane.

9. The foam wall structure of claim 1 , further comprising a home utility component selected from the group consisting of an electrical wire, a cord, a pipe, and a plumbing fixture disposed in the gap, and wherein the home utility component does not contact the foam layer.

10. The foam wall structure of claim 1 , wherein the polyiso board has a thickness of about ¾″ to about 2″.

11. The foam wall structure of claim 1 , wherein the foam wall structure has an ultimate load of ≥3,600 lbf when tested according to ASTM E72-05 in the absence of OSB and plywood.

12. The foam wall structure of claim 11 , wherein the foam wall structure has an ultimate load of ≥4,500 lbf when tested according to ASTM E72-05 in the absence of OSB and plywood.

13. A foam wall structure comprising:
a) a frame comprising:
a first member;
a second member spaced apart from the first member; and
two side members extending between the first and second members, wherein the first member, second member, and two side members each have a front surface and a rear surface that form the front frame surface and the rear frame surface of the frame;

b) at least one primary support member positioned between the two side members and extending between the first and second member, wherein the primary support member defines a front primary support surface and an opposite rear primary support surface corresponding to the front frame surface and rear frame surface;
c) foam insulation positioned over the front frame surface, the foam insulation positioned over the front frame surface consisting of polyiso board having a front face and a rear face, and a foil facer attached to at least a portion of the front face and the rear face, wherein the polyiso board is attached to and in contact with one of at least a portion of the front frame surface or at least a portion of the front primary support surface, such that the polyiso board, the first and second members, the two side members and the at least one primary support members define one or more voids within the frame; and
d) a foam layer received within at least a portion of one of the voids within the frame, wherein the foam layer adheres to at least a portion of the polyiso board,
wherein the foam layer is dimensioned to a position intermediate the front frame surface and rear frame surface such that a gap is formed within the frame between the foam layer and the rear frame surface, and
wherein the polyiso board has a thickness of about ½″ to about 3″.

14. The foam wall structure of claim 13 , wherein the foam layer does not overlie the front frame surface.

15. The foam wall structure of claim 13 , wherein the polyiso board is attached to the at least a portion of the front face of the first and second members and the two side members by fasteners.

16. The foam wall structure of claim 13 , wherein the polyiso board is attached to at least a portion of the front face of the first and second members and the two side members by one or more adhesives.

17. The foam wall structure of claim 13 , wherein the frame further comprises one or more secondary support members extending between two adjacent primary support members or a primary support member and a side member such that a secondary opening is formed within the frame, and wherein the secondary opening is free of foam, and a corresponding opening is present in the polyiso board.

18. The foam wall structure of claim 17 , wherein the frame further comprises one or more tertiary support members extending between two secondary support members, or between a secondary support member and the first member or the second member.

19. The foam wall structure of claim 13 , wherein the foam layer comprises polyurethane.

20. The foam wall structure of claim 13 , further comprising a home utility component selected from the group consisting of an electrical wire, a cord, a pipe, and a plumbing fixture disposed in the gap, and wherein the home utility component does not contact the foam layer.

21. The foam wall structure of claim 13 , wherein the polyiso board has a thickness of about ¾″ to about 2″.

22. The foam wall structure of claim 13 , wherein the foam wall structure has an ultimate load of ≥3,600 lbf when tested according to ASTM E72-05 in the absence of OSB and plywood.

23. The foam wall structure of claim 22 , wherein the foam wall structure has an ultimate load
