Abstract
Described herein is a wall assembly for use in walls of energy efficient residential or commercial buildings which can provide improved thermal resistance, moisture resistance and structural capacity. The wall assembly includes a frame assembly; a laminated outer sheathing layer; and a closed cell inner foam layer for coupling the layer to the frame assembly. Also described herein is a method of manufacturing the wall assembly.
Claims24
A wall assembly comprising:
- a frame assembly having a top member, a bottom member opposite to said top member, and a plurality of vertical members coupled to and extending between said top and bottom members with said frame assembly having an interior side and an exterior side opposite to said interior side;
- an outer sheathing layer having an interior surface and an exterior surface, said sheathing layer coupled to said frame assembly and extending from said exterior side of said frame assembly and terminating at an exterior surface of said sheathing layer;
- and
- a closed cell inner foam layer disposed between and bonded to plurality of vertical members of said frame assembly and bonded to said interior surface of sheathing layer for coupling said layer to said frame assembly,
- wherein the sheathing layer is laminated with a lamination.

A wall assembly comprising:
- a frame assembly having a top member, a bottom member opposite to said top member, and a plurality of vertical members coupled to and extending between said top and bottom members with said frame assembly having an interior side and an exterior side opposite to said interior side;
- an outer sheathing layer having an interior surface and an exterior surface, said sheathing layer coupled to said frame assembly and extending from said exterior side of said frame assembly and terminating at an exterior surface of said sheathing layer, said sheathing layer comprises at least one closed cell foam selected from the group consisting of expanded polystyrene;
- extruded polystyrene;
- and polyisocyanurate;
- and
- a closed cell inner foam layer comprising a sprayable foam selected from the group consisting of polyurethane foams, polyurea foam and combinations thereof disposed between and bonded to plurality of vertical members of said frame assembly and bonded to said interior surface of sheathing layer for coupling said layer to said frame assembly,
- wherein said sheathing layer is laminated with a lamination comprising a non-perforated, non-woven polyolefin permeable membrane or a spunbonded polypropylene fabric membrane.

2 more elements
A method of manufacturing a wall assembly comprising i) a frame assembly;
- ii) an outer laminated sheathing layer having an interior surface and an exterior surface coupled to said frame assembly, and iii) a closed cell inner foam layer coupling said frame assembly and said sheathing layer,
- said method comprising the steps of:
- providing the frame assembly having a top member, a bottom member opposite to said top member, and a plurality of vertical members coupled to and extending between said top and bottom members with said frame assembly having an interior side and an exterior side opposite to said interior side;
- applying said closed cell inner foam layer between and on said plurality of vertical members of said frame assembly and said interior surface of said sheathing layer;
- and
- coupling said sheathing layer to said frame assembly to form the wall assembly.
