An asymmetric structural insulated panel for building construction includes a generally planar insulating core such as of plastic foam or wheat-, straw-, or agricultural board. Adhered to a first surface of the insulating core is an outer facing of a conventional building material such as wood, oriented strand board (OSB), gypsum composite or cement. Adhered to a second opposed surface of the insulating core by means of a conventional adhesive is a thin, high strength sheet of paper impregnated with plastic such as polyisocyanurate. The plastic impregnated paper provides a high tensile strength for the structural insulated panel to accommodate large transverse loads on the panel. The panels may be incorporated in conventional stick construction employing 2.times. dimensional structural lumber members by attaching the panel's outer facing to one side of a 2.times. structural member after notching out an edge of the panel's insulating core. The panels have the same thickness as 2.times. structural members allowing the panels to be incorporated in a stick built wall, ceiling or roof without requiring modifications such as window or door jamb extensions. Narrow openings, e.g., less than approximately 4 feet, can be made in the panel in the field using a conventional circular saw.
