Hand Grade is a high-quality, high-performance, pre-finished engineered board of triple layered construction, with a nominal 6mm wear layer of European oak, WBP birch ply core and European oak base. The sheer size of these planks sets Hand Grade apart from the rest and are Cradle to Cradle (Bronze) and FSC® Certified. Hand Grade is a luxury finish for residential and commercial installations, and suitable over underfloor heating.
