Exclusive to Floor & Decor, NuCore® is 100% waterproof flooring. It looks and feels like wood, but NuCore can be installed where real wood cannot. With no acclimation time needed, it comes ready to install, right out of the box, and can be installed over most existing floors. It is also one of our easiest floors to install, and has a simple drop lock installation. Options are available with an attached cork underlayment for a quieter, warmer floor that is naturally resistant to odor-causing mold and mildew.
