A building panel having opposite sides and parallel beveled edges defined respectively by facing sheets and by the parallel sides of the first and last trapezoidal corrugations of a longitudinally corrugated sheet sandwiched between the facing sheets, the longitudinally extending trapezoidal spaces between the corrugated sheet and the facing sheets being filled with urethane or like insulating foam which bonds the facing and corrugated sheets together and forms a strong monolithic section. The facing sheets and corrugations are preferably made of cardboard, and the facing sheets desirably have colored, patterned or textured surfaces. The panel herein is further characterized in that a reinforcing, weatherproofing, and protective skin of translucent or transparent plastic is applied over the sides and edges of the panel through which the colored, patterned, or textured surfaces of the facing sheets are visible. The parallel beveled edges of the panels permit such panels to be assembled in edge-to-edge sealed relation over a foundation wall, or in partially overlapped and sealed relation on the rafters of a sloping roof, or in side-by-side relation with resilient strips therebetween on a flat or sloping roof. When used as horizontal siding in home construction, the edges of the panels may be placed in abutting engagement with such edges sloping downwardly away from the structure so that the joints are self-draining. A suitable caulking material may also be placed between the joints to provide a better seal between panels if desired. Alternately, the panel edges may be provided with extruded plastic or like strips for nailing directly to the wall studs and for interlocking the edges of successive panels in partially offset relation to resemble conventional siding construction. When used as vertical or diagonal siding in home construction, caulking may also be provided at the joints, or plastic coated and foam filled cardboard battens may be provided and sealed between successive panels or sealing strips may bridge the joints between adjacent panels.
