The panel (10) has a rigid foam layer (12) of synthetic organic polymeric foam, a protective weathering layer (14) of thermoplastic sheet material and a generally flexible backer layer (16) of stereoreticulate material interposed between the foam and weathering layers. Interstices (30) of the backer layer (16) adjacent the foam layer (12) are filled with the resin of the foam layer (12) providing a physical bond and a protective substrate (32) for the foam layer. The weathering layer (14) may be adhered to the backer layer (34) by application of heat.
