ABSTRACT:
A generally flat structural panel includes a center foam core and first and second opposed outer facings, or sheets. The first and second outer facings of the panel may be comprised of virtually any of the more common building materials such as wood, gypsum, cement or wallboard. The insulating core of the panel is preferably comprised of a rigid plastic foam such as expanded polystyrene, extruded polystyrene, urethane or polyisocyanurate. The panel has first and second opposed edges which each include U-shaped grooves formed from adjacent edges of the outer facings and the inner foam core. A spline having an insulating core and a pair of outer facing metal strips extending the length thereof is inserted in the facing grooved edges of a pair of the above-described panels for coupling the panels together in a sealed manner. The spline extends the length of the two panels, with its insulating core preferably comprised of a plastic foam and its opposed metal strips preferably comprised of aluminum or galvanized steel. The spline is affixed to the panel edges by means of a structural adhesive for securely connecting the two insulated panels.
