Abstract: A building wall panel (20) adapted for mounting on a building frame includes an exterior facing formed from a plurality of thin stone panels (22) of for instance granite or marble, backed and interconnected by a layer (28) of glass fiber-strengthened concrete underlying the panels and covering and engaging anchor clips (24) secured to the backs of the stone panels (22). The backing layer (28) is bonded to a metal support frame (30) by additional amounts of glass fiber-reinforced concrete (29) overlaying portions of anchor members (36) carried by the support frame and adjacent portions of the backing layer (28). A method of forming the building wall panel (20) involves placing granite or marble panels (20) face down in a form (48), mounting anchor clips (24) or pins (61) in the backs of the stone panels, and spraying a layer of slurry (55) formed from a mixture of concrete and chopped glass fiber strands, over both the panels (22) and the anchor clips (24 ) or pins (61).

Abstract: A panel adapted for mounting on a building, the panel being formed from a plurality of thin panels of a selected stone facing material, such as granite or marble, backed and interconnected by fiberglass-strengthened concrete underlaying the plurality of thin panels and covering and engaging anchor means mounted in the backs of the stone panels. The method of forming the building panel involves placing the granite or marble panels face down in a form, mounting anchor means in the backs thereof, and overlaying both the plurality of thin panels and the anchor means with a fiberglass-strengthened concrete mixture, and curing the mixture both within and without a support form.
