With being the largest LVT plank on the market, COREtec Pro Galaxy is in a category all its own. Rigid plank technology allows easy handling and installation making COREtec Pro Galaxy a great alternative to glue down LVT, solid locking LVT, or laminate flooring. The patented construction of COREtec Pro Galaxy features our innovative COREtec core structure, which is an extruded core made from recycled wood and bamboo dust, limestone, and virgin PVC. Since COREtec Pro Galaxy products are 100% waterproof, they can be installed in wet areas and will never swell when exposed to water. COREtec Pro Galaxy is inert and dimensionally stable; it will not expand or contract under normal conditions. Further, COREtec Pro Galaxy never needs expansion strips in large rooms. Each COREtec Pro plank has an attached cork underlayment for a quieter, warmer vinyl floor that is naturally resistant to odor causing mold and mildew. COREtec Pro is GREENGUARD GOLD Certified for Indoor Air Quality to help keep your home healthy and happy.
