Abstract: 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 between 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 outwardly of the back plane. A row of fastener receiving 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 substantially on said back plane. The profile further includes an upper edge portion above the row of fastener receiving depressions which terminates along the upper edge of the panel.

Abstract: A building panel of wood composite material includes inner and outer faces outlined by opposite ends and upper and lower edges. The panels are adapted to be placed end-to-end in courses or rows arranged in parallel to extend upwardly from a lower edge or eave to cover a building wall or roof structure. Each panel includes an outer face having a lower portion of substantial surface area adapted for exposure to the weather and an upper portion of relatively smaller surface adapted to underlie one or more panels in a next higher course laid in overlapping relation therewith. A large lower portion of the outer face is formed with a surface embossed to resemble a plurality of individual shingle elements positioned in side-by-side relation. Grooves are formed in the outer face of the panel between adjacent shingle elements and each groove tapers from a minimum depth adjacent the upper portion of the outer face to a maximum or greater depth adjacent the lower edge of the panel.
