Abstract
A wall covering comprising a plurality of plastic molded panels each having a relatively thin body portion formed with rows of simulated building elements. The panels are mounted on a support surface in a plurality of horizontal courses with a side marginal edge region of one panel overlapping and sealingly engaging an underlying side marginal edge region of the adjacent panel and a lower marginal region of a panel in one course overlying an upper marginal region of a panel in a lower course. Each panel is provided with frangible locating means for positively locating an interlock lip of the overlying panel in predetermined engaged relation with interlock flanges of an underlying panel. The interlock flanges of the panels are provided with reinforcement ribs to prevent breakage when the panels are exposed to weather extremes and undergo thermal expansion or contraction. Finally, each panel is provided with side interlock means which enhance the panel's resistance to buckling during installation and use.
