Abstract
Abstract A load bearing wall panel unit is comprised of a pair of facially opposed co-extensive panels connected together by edge fasteners and has a core of foam-like material located between the panels. The unit has an outer layer of weatherproofing material and is connected to adjacent units by tongue and groove fasteners. Tongue and groove fasteners are also used to connect the units to a building foundation and roof.
