Abstract
An improved building panel for wall and roof systems comprises a core of expanded polystyrene or polyurethene foam faced with a layer of wood particle board of gypsum board covered by a layer of steel fastened to the particle board of gypsum so that during fire conditions, gases of vapors evolved from particle board of gypsum board can escape from the interior of the panel but air exterior to the panel is prevented from entering, thereby ensuring that the load-bearing capacity of the panel is maintained for an extended period of time during a fire.
