A generally planar structural insulated panel for use in the wall of a building structure includes an inner core of insulating material such as plastic foam. Disposed on and attached to opposed surfaces of the insulating core are outer facings in the form of thick sheets of paper impregnated with plastic such as urethane, polystyrene or polyisocyanurate. The plastic impregnated paper (PIP) sheets are 0.14'' to 0.70'' thick and extend several inches beyond the edges of the panel's insulating core. The PIP sheets provide the panel with high tensile strength and the peripheral edges of the PIP sheets are adapted to receive coupling pins such as nails, screws or staples for mounting the panel to 2x dimensional lumber members in the building structure. The high tensile strength of the PIP sheets also provides secure mounting of the panel to the adjacent structural members. Compression struts are provided within the panel's insulating foam core and inside the panel's outer PIP facings to accommodate large axial loading on the panel. The inner PIP sheet may have attached thereto a gypsum or cementous composite sheet to provide a finished panel when installed in a building structure. Adjacent PIP facings of a pair of structural panels may be arranged in an overlapping manner and connected to a structural member such as a spline or stud to provide a high strength, sealed connection between the panels.
