The Warehouse Sandwich Panel combines an expanded polystyrene (EPS) foam core with structural aluminum or steel skins for industrial warehouse construction. The snap-lock design enables quick interlocking installation across roofs, walls, and floors while creating continuous insulated barriers that minimize thermal bridging and reduce heating and cooling costs by up to 58%.
Available in 12-inch, 16-inch, 2-foot, or 4-foot widths with customizable lengths from 3 to 48 feet, panels feature thickness options of 3, 4, or 6 inches supporting clear spans up to 22 feet under specified loads. Steel skins come in 24 or 26 gauge prepainted or bare galvalume, while aluminum options include .024 or .032 inch thicknesses with EPS foam densities of 1.5 pounds per cubic foot.
The concealed fastener system provides wind uplift resistance and structural stability against hurricane and earthquake forces. Standard colors include white, eggshell, wheat, and dark bronze with optional stucco or cedar embossed finishes backed by 40-year warranties against peeling and 15-year structural integrity coverage when properly installed over solid substrates with minimum 3:12 roof pitch.
