Building panel
First Claim
1. A unitary building panel formed of composite wood fibrous material having generally parallel, inner and outer faces outlined by opposite ends and by upper and lower edges, said opposite ends of said panel adapted to closely face the end of an adjacent panel in the same course, said outer face having a large lower portion adapted for exposure to the weather with a substantially greater surface area than a narrow upper surface portion having a relatively smaller, substantially planar, surface area adapted to underlie a generally planar lower portion of the inner face of one or more of said panels laid up in a next higher course, said lower surface area of said outer face being deeply embossed to resemble a plurality of shingle-like elements laid up in a common course with each of said shingle like elements separated from an adjacent element by a groove tapered from a shallow depth adjacent an upper end adjacent said narrow upper surface portion toward a maximum depth opening into said lower edge of said panel, one of said opposite ends having a laterally outwardly projecting integral spacer adjacent an end of said smaller narrow upper surface portion extending laterally outwardly from said one of said opposite ends to provide an expansion space of a width generally similar to the width of said grooves between a lower portion of said one end and an adjacent end of an adjacent panel positioned in the same course.

Abstract
A building panel having inner and outer faces outlined by opposite ends and an upper and lower edges with opposite ends of the panel adapted to closely face the ends of adjacent panels in the same course. The outer face of the panel includes a lower portion of substantially greater surface area adapted for exposure and an upper portion of relatively smaller surface area adapted to underlie a lower portion of the back face of one or more panels laid up in the next higher course. At least one of the opposite ends of the panel is formed with a spacer projection adjacent the smaller upper portion thereof extending outwardly to provide an expansion space between a lower portion of said one end and an end of an adjacent panel positioned in the same course or row. The provision of a spacer eliminates the need for an installer to attempt to provide for adequate expansion space between panel ends when installing the panels and automatically insures that an expansion space of the desired width is present and not forgotten during installation of the panels.
