Abstract: A kit for assembling prefabricated wall panels includes prefabricated wall panels and clips. Each side of the prefabricated wall panels is configured to form a side-lap joint and at least a tongue and groove joint upon assembly. Each clip includes a flange having a plurality of holes and a web that is connected to an edge of the flange and is at least 4 inches long. The clips may allow for greater panel spans and/or provide improved wind resistance. For assembling the prefabricated wall panels to a building structure, a clip is placed on a cheek surface of the side-lap joint of one of the prefabricated wall panels. Fasteners are threaded through the prefabricated wall panel to clamp an edge of the prefabricated wall panel between the clip and the building structure.

Abstract: A roof panel includes a fascia plate having a pair of vertical legs extending from opposite edges of the fascia plate with a receptacle formed into an upper end of each of the pair of vertical legs so that the receptacle opens outwardly relative to the fascia plate. An insulating foam is bonded to the fascia plate and to a liner plate that has a tongue and groove formed on opposite edges of the liner plate.
