Great question! The short answer- we like to call it “luxury vinyl outdoor flooring”. IntelliDeck is a waterproof deck membrane that is .060” x 72”. It has a PVC layer that is printed with attractive designs to complement any deck, especially those over living spaces. It has a 3 ounce non-woven polyester back layer to promote glue adhesion. IntelliDeck is 100% made in the USA in Winchester, Virginia by a company that has been in business since 1896.
