A building panel has a unitary foamed core, and a unitary cover layer of resinous polymeric material covering the core and covering a bottom edge or drip edge and an upper edge of the panel. A system for installation of adjacent panels includes the adjacent panels having vertical clip-receiving grooves slidably receiving narrow edges of a clip. The clip holds adjacent panels in coplanar abutting relationship to minimize movement while installed on a wall of a building.

An apparatus for making a shingle, together with the shingle made thereby, is provided, in which one or more thermoplastic materials are extruded or co-extruded to form an extrudate, with the extrudate being cut into a preliminary shingle shape, which is allowed to dissipate heat, and then is delivered to a compression mold, wherein the preliminary shingle shape is compression molded to substantially its final dimensions and is then discharged from the mold and allowed to cool.
