Abstract: The present invention is directed to a building panel having a laminate structure, the laminate structure including a topcoat layer comprising a first intumescent composition, a cellulosic veneer layer, an adhesive layer formed from an adhesive composition comprising a second intumescent composition, and a metallic substrate layer and wherein the cellulosic veneer layer is at least partially bonded to the metallic substrate by the adhesive layer. The resulting building panel exhibits superior flame retardancy resulting in a Class A fire rating, according to ASTM E-84.
