Abstract
The floor covering includes multiple layers including a non-woven base layer, a VAE precoat applied to the non-woven woven base layer and overlaid by a first PVC layer. A fiberglass mat is applied over the first PVC layer and a second PVC layer is applied over the mat. A woven PVC layer is laminated by heat and pressure to the underlying second PVC layer. The woven PVC layer comprises monofilament or multifilament cores, preferably but not limited to, polyester filaments overlaid by a PVC coating.
