BUILDING PANEL Abstract of the Disclosure A building panel for surfacing exterior and interior wall and roof structures comprises an outer shell formed of relatively thin, molded hardboard material having upper and lower edges, opposite ends, a molded outer surface adapted for exposure to the weather and a back surface. The shell is formed with a cross-sectional profile extending transversely be- tween the upper and lower edges comprising a lower edge portion extending upwardly and outwardly of the lower edge of the panel and a back plane of the panel joining an intermediate portion which is spaced out- wardly of the back plane. A row of fastener receiv- ing depressions is formed along an upper edge of the intermediate portion and these depressions have a base spaced inwardly of the surrounding surface with a back face of said depression bases lying substan- tially on said back plane. The profile further in- cludes an upper edge portion above the row of fastener receiving depressions which terminates along the upper edge of the panel. The molded shell profile has an overall dimension between an outer face of the inter- mediate portion and said back plane that is substan- tially greater than the nominal wall thickness of the shell material between the outer and back surfaces thereof.
