Abstract: A composite stone panel can comprise a stone slab. A partially metallic panel backer is coupled to the stone slab and can further comprise a core material layer, a first interface layer disposed on a first surface of the core material layer, and a second interface layer disposed on a second surface of the core material layer opposite the first metal interface layer. The stone slab can further comprise a length greater than 1.2 meters (m), a width greater than 0.6 m, and a thickness in a range of 0.2-1.5 centimeters (cm). The core material layer can comprise a thickness greater than 3.75 millimeters and can further comprise polyethylene and optional fibers. The first and second interface layers can comprise a thickness of aluminum in a range of 0.21 millimeters (mm) to 0.30 mm. Accordingly, the composite stone panel can comprises a thickness in a range of 0.6-3.0 cm.
