PLASTIC BUILDING PANEL AND METHOD FOR MAKING SAME

摘要

A plastic building panel having a thermoformed face and a thickened upper edge. The upper edge has a flange forming a downwardly facing U shaped opening. A flange at the bottom edge of the panel forms an upwardly facing U shaped opening. The panel is formed by first thermoforming a sheet of plastic and then heating along longitudinal fold lines near the edges of the panel and folding the edges along the fold lines to at least partially form the finished panel.
