COREtec Plus Treasure Pine Premium is the latest, and most comfortable step in the evolution of luxury vinyl flooring. Beneath the realistic visuals and textures, the patented COREtec construction has been enhanced to create a softer, warmer and quieter floor. COREtec Plus Premium is 100% waterproof, so it can be installed in wet areas as it will never swell when exposed to water. COREtec Plus is inert and dimensionally stable; it will not expand or contract under normal conditions, making it a great alternative to glue down LVT, solid locking LVT, or laminate flooring. Further, COREtec Plus Premium never needs expansion strips in large rooms. Each COREtec Plus Premium plank features an attached cork underlayment that is naturally resistant to odor causing mold and mildew.
