Abstract: A building assembly includes a plurality of expanded polystyrene wall panels, headers, sill panels, U blocks, U block caps, roof panels, and connectors. Each U block includes rebar and at least one of concrete and cementitious material in a recess or void therein. Each U block cap when joined to the U block creates an enclosed void in the U block which holds the rebar and concrete and/or cementitious material. A plurality of capped U blocks joins a plurality of wall panels, headers, and sills to form a wall structure. A plurality of U blocks are placed on a top surface of the wall structure. A roof assembly including a plurality of U blocks, H connectors, T connectors, and combinations thereof connected to roof panels to form a rigid roof assembly. A coating of cementitious material provides additional structural rigidity and resistance to impact, fire, water, mold, mildew, and insects.

Abstract: The present invention relates a low cost, highly insulated light weight prefabricated building assembly capable of providing a swift, efficient and economic construction of exterior walls, interior walls and roofs to form a sturdy building assembly. The present invention includes a plurality of exterior wall panels; a plurality of styrofoam exterior connection blocks; the plurality of exterior connection blocks being capable of joining the plurality of exterior wall panels that form an exterior wall of the building; a plurality of roof panels, where the plurality of roof panels form a roof of the building; a plurality of interior wall panels; and a plurality of interior connection blocks. The plurality of interior connection blocks are used to connect the plurality of interior wall panels that form at least one interior wall of the building.
