ABSTRACT:
An insulated building is constructed of panels that have a rigid, closed cell foam sandwiched between, and bonded to high tensile strength outer sheets. The outer sheets extend beyond the edges of the foam to provide grooves along the edges of the panels. The panels are joined together by elongate edge connectors. Each edge connector is formed by extrusion of a high tensile strength outer layer enclosing a rigid foam core. From the central body of the edge connector, tongues extend out at fixed angles corresponding to the angle between panels. The tongues are bonded into the grooves in the panel edges. End connectors fit telescopically into the ends of adjoining edge connectors and are bonded in place to form an integrated frame interlocked with the panels.
