The only requirement is a vapor barrier if your Waterproof Cork Floor is floated over concrete. If you are gluing your floor down a vapor barrier is not required. Additional underlayment is optional in either case - please see the installation instructions for additional information, located on the product detail page under downloads, direct link below for your convenience. https://www.greenbuildingsupply.com/c...
