A generally rectangular, building-wall panel comprising: an interior polymeric sheet and an exterior polymeric sheet bonded together at their peripheral edges and at selected areas within their peripheral edges to define a panel, a central panel area defining a door which is bordered on at least three sides by a planar surface area wherein said sheets are bonded together, which central panel area may be cut from said panel in said planar area, said central panel area having patterned offset areas to reinforce said central panel area, and an offset area extending from one edge of said central panel area to the adjacent edge of said panel wherein said molded sheets are bonded together and one side of said offset area is at a plane parallel to the other side, said one side being spaced substantially the thickness of said two sheets from said other side, which offset area may be cut at its midpoint to separate said panel whereby the one and said other side may be placed in overlapping relationship to form a frame smaller than said central panel area, said offset and overlap provides said frame in one plane from said surface area adjacent the central panel area.
