The panel has slotted zones, continuous unslotted zones and continuous connective zones, all of which may be made of plastics. In the unslotted zones impact strength is high. At the same time, the modulus of elasticity in the connective zones allows the panel to be bent to small radii of curvature. PREFERRED FEATURES:- The panel (30) is extruded. It commences as an integral foam panel. It is coextruded as a multilayer and has decorative facings (17) of higher density. It is colored at the surface, or throughout and a decorative sheet may is applied. A molded-on flexible lip seal is located on at least one edge. At one end there is a groove for a fastening. The groove is outwardly open, and there is a T-slot in the rear surface of the panel.
