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 2.times. 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.

1. A structural panel for use with 2.times. stick structural members in a building structure, said structural panel comprising:a generally planar insulating core having plural peripheral edges and first and second opposed sides; first and second high tensile strength plastic impregnated paper sheets respectively attached to the first and second sides of said insulating core, each of the plastic impregnated paper sheets having plural edge portions each extending outwardly beyond an adjacent edge of and in spaced relation from said insulating core; and connecting pins inserted through adjacent edge portions of the first and second impregnated paper sheets and into an adjacent 2.times. stick structural member for mounting the structural panel in the building structure.
