Abstract
Abstract A moisture, fungi, and alkaline salt resistant laminate for floor, wall or other covering purposes comprising a moisture permeable backing layer, preferably a sized asbestos felt, a barrier layer overlying the backing layer resistant to penetration and degradation by moisture, fungi and alkaline salts, preferably a thermoplastic resin such as polyvinyl chloride or mixtures of resins having the mentioned characteristics, a resinous body layer overlying the barrier layer preferably of an open cellular character and a resinous wear layer overlying the body layer.
