Structural Panels Inc. Rockwall Wall Panels are constructed of 26 gauge steel skins, mineral fiber board insulation and tongue-and-grooved vertical joints. The panels are 46-1/2 in. wide (joints 46 in. on centre when assembled) available in thicknesses of 4 in., 5 in., and 6 in.
Rockwall XP is an insulated sandwich wall panel consisting of steel skins bonded to a mineral wool core with a tongue and groove joint on each side. The panels are 4 inches thick, 46-1/2 in. wide, and up to 25 ft. long.
