Abstract
A building wall panel having an exterior facing formed from a glass fiber reinforced concrete bonded to a metal wall panel support frame formed from a plurality of vertical members having a plurality of flanges thereon by a layer of glass fiber reinforced concrete overlaying both a portion of the rear surface of the exterior facing and the flange abutting the exterior facing at intervals along the length of each vertical member. A method of forming the building wall panel involves spraying a first layer of slurry, formed from a mixture of concrete and chopped glass fiber strands, on a flat smooth surface between elongate members secured thereto and interconnected to form building wall panel mold. A metal wall panel support frame formed from a plurality of vertical members is placed over the first layer of slurry such that a flange disposed on each vertical member abuts the first layer of slurry. A second layer of slurry is sprayed over a portion of the flange on each vertical member and over a portion of the first layer of slurry. Both layers of slurry are cured and the completed building wall panel is removed from the surface and the mold.
