Wood flooring is very sensitive to the effects of moisture. When you reduce moisture vapor rising from beneath moisture sensitive wood flooring, you help increase the useful life and protect the appearance of finished floors. To help win the battle, the Fortifiber Building Systems Group offers HWD-15 as economical insurance to reduce most moisture-related flooring problems.
HWD-15 hardwood floor underlayment is an extremely effective moisture vapor retarder specifically designed for optimum performance in wood flooring applications. Consisting of a single layer of kraft paper saturated with asphalt, HWD-15 is a permeable vapor retarder. It reduces vapor flow, without trapping moisture.
