Abstract: An asymmetric structural insulated panel for building construction includes a generally planar insulating foam core such as of expanded polystyrene, urethane or polyisocyanurate plastic. Adhered to a first surface of the insulating foam 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 foam core by 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. Elongated “nailing” members may be affixed in a spaced manner to the inner or outer surface of the plastic impregnated paper to also provide this surface of the panel with high compressive strength and to permit the panel to withstand large axial loads.

Abstract: A post frame building utilizing wood support posts having bottom portion of the posts sunken into the ground. An encapsulating sleeve for each underground portion of the posts providing a positive barrier against deterioration by ground contact. The sleeve may be trimmed at ground level or higher as desired.
