Go big and go home. COREtec Plus XL is in a category by itself. Rigid plank technology means handling and installation is no big deal, which makes COREtec Plus XL a smart alternative to glue down LVT, solid locking LVT, or laminate flooring. COREtec Plus XL features our innovative and patented COREtec core structure, which is an extruded core made from an exclusive mix of recycled wood and bamboo dust, limestone, and virgin PVC. This makes COREtec Plus products 100% waterproof, so they can be installed in wet areas and will never warp of swell when exposed to water. COREtec Plus XL is inert and dimensionally stable, which means it won’t change size due to heat or humidity under normal conditions and never needs expansion strips in large rooms. An attached cork underlayment results in a quieter, warmer vinyl floor that is naturally resistant to odor causing mold and mildew. COREtec Plus XL is also GREENGUARD GOLD Certified for Indoor Air Quality.
