A panel made of sheet metal, synthetic resin, or the like and adapted to be mounted shingle-fashion with a plurality of other such panels to an upright wall is of generally rectangular shape with upper and lower end edges and lateral side edges. Between these edges the panel has when mounted a horizontal bend subdividing it into an upper half and a lower half. In the upper half the panel has an upper central substantially planar region which is surrounded by an upper downwardly U-shaped non-planar attachment portion by means of which the entire panel is secured to the upright wall. The lower half has a lower central substantially planar region which is contiguous at the bend with the upper planar region and generally coplanar therewith in a relaxed unmounted condition of the panel. A lower upwardly U-shaped contoured non-planar portion has an inner periphery connected directly to the lower planar region so as to surround the same and an outer periphery which is connected directly to a lower outwardly directed flange at the edges of the lower half. When mounted the flange is generally coplanar with the upper planar region and the entire outer face of the lower half is exposed, with each side of the lower half overlying a corresponding side of an upper half of an underlying panel and the lower end edge of the panel overlying the upper end edge of an underlying panel. |
