Claim 18:
19. A method of manufacturing a wall assembly comprising i) a frame assembly; ii) a sheathing layer extending from an interior surface to an exterior surface coupled to said frame assembly, said sheathing layer comprising at least one closed cell foam selected from the group consisting of expanded polystyrene, extruded polystyrene, and polyisocyanurate; and graphite particles, iii) a closed cell inner foam layer coupling said frame assembly and said sheathing layer, and iv) an outer fiberboard,
said method comprising the steps of:
1. providing said 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;
2. 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;
3. coupling said sheathing layer to said frame assembly; and coupling said outer fiberboard to said sheathing layer to form said wall assembly.
