Glass fiber reinforced concrete (GFRC) may be used to replace conventional concrete backup to stone veneer precast panels, thereby producing a lightweight panel. Toein spring clips connect stone veneer to GFRC backup. A bondbreaker separates the GFRC and stone veneer to allow differential movement. A steel stud frame commonly functions as a panel stiffener. The stud frame is attached to the GFRC skin by means of flex anchors.

The gravity load of the GFRC skin is transferred to the stud frame by two methods: (1) flex anchors only, and (2) gravity anchors in addition to flex anchors. The stud frame is attached to the building structural frame, and the loads of the panel are carried through the stud frame to the panel connection points on the structure.
