A type of rigid core flooring, Waterproof Vinyl (WPC) is a variety of vinyl whose core is comprised of wood plastic composite, made from a combination recycled wood pulp and plastic. This type of core is thicker compared to Rigid Waterproof Vinyl (SPC). As a result, WPC offers more cushion underfoot, creating a more comfortable walking experience and better soundproofing. As a rigid product, it is also able to withstand heavy traffic and spills.
