AquaBarB - In the battle against interior moisture damage, the best defense is a strong offense. When you block moisture vapor from creeping underneath finish materials or reaching moisture sensitive substrates, you help increase the useful life and appearance of finish surfaces. To help win the battle, the Fortifiber Building Systems Group offers Aquabar “B” as inexpensive insurance to reduce moisture-related problems.

Aquabar “B” floor and tile underlayment is an extremely effective moisture vapor retarder for use in a variety of interior construction applications. Consisting of two layers of kraft paper laminated with asphalt, Aquabar “B” is a non-reinforced 30/30/30 duplex type Grade “B” paper.

HWD15 - 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. HWD passes CA01350 for indoor air quality, the most stringent requirement in the country.

Silicone Vapor Shield - Non-toxic, zero VOC, recycled vapor barrier for hardwood flooring

Silicone Vapor Shield (SVS) is the best-rated underlayment paper for moisture protection of hardwood flooring over plywood or OSB subfloors. Rather than trapping moisture, this
semi-impermeable vapor barrier, allows moisture to slowly dissipate through the flooring without mold developing and without causing cupping or buckling of the flooring. It's non-toxic, eco-friendly, and a zero VOC alternative to red rosin paper and asphalt impregnated paper (tar paper). Silicone Vapor Shield is approved and recommended by the National Wood Flooring Association (NWFA) for nail down hardwood flooring. SVS can also be used under engineered hardwood, bamboo, cork or Marmoleum flooring when applied over OSB or plywood subfloors.
