A composite cladding panel for application primarily to the exterior of buildings, comprises a core layer of lightweight insulating foam proving a thermal insulation of at least R10, said insulating foam being encapsulated in a layer of fluid impermeable material to inhibit the passage of vapor and gasses therethrough, an outer sheet consisting of at least one finishing panel adhering to an outer surface of said core layer, and an inner structural insulating sheet, thermally compatible with the expansion characteristics of said outer sheet, adhering to an inner surface of said core layer to provide structural integrity to said panel and facilitate attachment thereof to a building structure. The panel is of lightweight construction and useful especially in the environmentally efficient finishing of buildings.
