At-a-glance signals
Stone honeycomb/laminated panels using 3?8 mm stone on lightweight backing, total thickness 12?25 mm and typical weight 14?20 kg/m? (manufacturer data); substantial weight reduction vs solid stone cladding.
Overview
Executive summary
Ultra-thin stone veneer composite panels bond 3?8 mm stone to an aluminum honeycomb or FRP backing. Manufacturer data for stone honeycomb panels list total panel thicknesses of 12?25 mm and typical unit weight of 14?20 kg/m?, depending on stone type and backplate. These systems deliver large weight reductions versus solid stone while keeping the stone finish intact.
