The COREtec Plus Premium 7" Noble Oak Collection offers realistic visuals and textures for a look that competes with traditional hardwood flooring. This luxury vinyl flooring is complete with the patented COREtec construction that offers a warmer and quieter floor. It's 100% waterproof so it can be installed in wet areas. It will never swell or warp when exposed to water. COREtec Plus is also inert and dimensionally stable, so it will not expand or contract under normal conditions. Each COREtec Plus Premium plank features an attached cork underlayment that is naturally resistant to odor causing mold and mildew.
