Patent attributes
Construct a wall assembly by: (a) providing a support structure with spaced apart structural members; (b) affixing a thermally insulating layer of polymeric foam boards to the structural members, the foam boards achieving a Class A rating according to ASTM E-84; (c) covering seams between polymeric foam boards with a sealing tape; (d) affixing a plurality of fasteners through the thermally insulating layer to structural members with the fasteners extending beyond the outside surface of the thermally insulating layer; (e) attaching a façade selected from metal panel, metal-composite-metal panels, fiber reinforced cementitious siding veneer and materials having a thickness of at least 1.9 centimeters (0.75 inches) that qualify as “non-combustible” according to ASTM E136 to the fasteners and within five centimeters of the thermally insulating layer; and desirably (f) applying a spray polyurethane foam material to seal gaps through the thermally insulating layer; the process being free of applying gypsum sheathing layer or wood-based sheathing between structural members and the thermally insulating layer.
