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, an outer fiberboard, and a closed cell foam layer. The fiberboard is laminated with a lamination such as a non-perforated, non-woven polyolefin permeable membrane. The closed cell foam layer couples the frame assembly and the outer fiberboard. Also described herein is a method of manufacturing the wall assembly.
Claims23
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 fiberboard having an interior surface and an exterior surface, said fiberboard coupled to said frame assembly, extending from said exterior side of said frame assembly and terminating at an exterior surface of said fiberboard;
- and
- a closed cell foam layer disposed on and between said plurality of vertical members and extending from said exterior side of said frame assembly, said closed cell foam layer couples said fiberboard to said frame assembly.
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 fiberboard having an interior surface and an exterior surface, said fiberboard coupled to said frame assembly, extending from said exterior side of said frame assembly and terminating at an exterior surface of said fiberboard;
- and
- a closed cell foam layer comprising a sprayable foam selected from the group consisting of polyurethane foams, polyurea foam and combinations thereof disposed on and between said plurality of vertical members and extending from said exterior side of said frame assembly, said closed cell foam layer couples said fiberboard to said frame assembly,
- wherein said fiberboard is a fiberboard made of pressure laminated plies of cellulose fibers, laminated with a lamination comprising a non-perforated, non-woven polyolefin permeable membrane.
A method of manufacturing a wall assembly comprising i) a frame assembly;
- ii) an outer fiberboard;
- and iii) a closed cell foam layer coupling said frame assembly and said outer fiberboard;
- 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 foam layer on and between said plurality of vertical members and extending from said exterior side of said frame assembly;
- and
- coupling said fiberboard to said frame assembly to form said wall assembly.
