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. The underlying side marginal edge region of each panel is formed with a plurality of laterally extending interlock flanges each having a nailing aperture, and the overlapping side marginal edge region of the adjacent panel has a plurality of integrally formed hooks for engaging an upper peripheral edge of a respective one of the interlock flanges for positively interlocking the overlapping sides and for maintaining sealing engagement therebetween. A corner molding is provided for receiving respective ends of the panels at a corner in a manner which enhances the aesthetic appearance of the finished installation.

Abstract: A wall covering comprising a plurality of plastic molded panels each having a relatively thin body portion formed with rows of simulated shake shingles. The panels are mounted on a support surface, such as a wall or roof, in a plurality of vertically spaced horizontal courses with a lower marginal edge region of the panels in one course overlapping and sealingly engaging the upper marginal edge regions of the panels in the course immediately below and with side marginal edge regions of adjacent panels overlapping in sealing engagement. The side marginal edge regions of each panel are formed with a plurality of vertically spaced integrally formed hooks depending from the underside thereof for snap action insertion through respective hook receiving apertures formed in the underlying side marginal edge region of the adjacent panel for maintaining the overlapping marginal edge regions of the panels in engaged relation.

Abstract: A decorative wall covering and method of installation. The wall covering includes a plurality of identically molded panels each having first and second predetermined laterally spaced vertical cutting lines and being formed with horizontal rows of laterally spaced simulated shake. The first panel of each alternate course in the vertical direction is cut along the first cutting line and the first panel of every other course is cut along the second predetermined cutting line, whereby the lowermost row of simulated shake of the panels of each course are automatically offset from the uppermost row of the panels in the course immediately therebelow.

Abstract: A wall covering comprising a plurality of plastic molded panels each having a relatively thin body portion formed with rows of simulated of shake shingles. The panels are mounted on a support surface, such as a wall or roof, in a plurality of vertically spaced horizontal courses with a lower marginal edge region of the panels in one course overlapping the upper marginal edge regions of the panels in the course immediately below and with side marginal edge regions of adjacent panels also overlapping. The overlapping marginal edge regions each are formed with a plurality of parallel water barrier ridges for impeding movement of water outwardly over the peripheral edges of the underlying marginal edge region, as well as into nail mounting holes. The water barrier ridges are discontinous so as to impede outward water movement, while allowing drainage of water in a downward direction.
