ABSTRACT Construction and use of a modular system of prefabricated building panels is described: in the system a structural frame of characteristically OSB (oriented strand board) or plywood is formed in jigs under compression, the integrity of the frame being assured by the rabbeting or dovetailing of all joints and the design of the supporting channels and l-struts, and by the gluing and nailing of all parts. In the preferred embodiment for load-bearing and insulating wall, floor and ceiling panels additional rigidity is provided by fire-retardant expanding foam insulation which hardens under pressure inside the frame. Electrical conduits are pre-set into the frame, which is offset from fastened interior and exterior sheathing boards so that the finished panel will mate in a rabbet joint with an identical panel; thus a series of such panels can be connected in the field with ease. In addition, the exterior sheathing of wall panels extends down to exactly cover the thickness of a joining floor member to prevent thermal loss and wind penetration; and a special comer wall panel has its dimensions reduced by the thickness of a joining wall member, so that the joint can be accommodated without compromising the horizontal modularity of the multiple identical-panel design.
