Decorative wall covering with improved interlock and corner construction

DETAILED DESCRIPTION It is an object of the present invention to provide a wall and roof panel that is adapted for more reliable interlocking engagement along its peripheral sides for maintaining a sealed condition between overlapping marginal edge portions of the panels and for enhancing the realistic and aesthetic appearance of the assembled wall covering, even when mounted on slightly irregular support surfaces.
Another object is to provide a synthetic wall and roof panel which permits more secure mounting of the panel on the support surface and easier and more effective interlocking of overlapping side marginal edge regions.
A related object is to provide such a panel which enables nailing of the panel to the support surface along top and side marginal edge regions for more secure installation, while not encumbering the interlocking engagement of subsequently installed panels.
A further object is to provide a wall and roof panel of the foregoing type which is relatively simple in construction and which lends itself to economical manufacture and ease of installation.
Yet another object is to provide a more aesthetic and naturally appearing corner construction for synthetic wall and roof panels formed with relatively uniform building elements, such as perfection shake.
Other objects and advantages of the invention will become apparent upon reading the following detailed description and upon reference to the drawings, in which:
