## Description

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. 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 surface finishes. To help win the battle, the Fortifiber Building Systems Group offers Aquabar B as a great tile underlayment and inexpensive insurance to reduce moisture-related problems.
