Ideal for wood flooring and tile applications. When you block moisture vapor from creeping behind finish materials or reaching moisture sensitive substrates, you help increase the useful life and appearance of finish surfaces.

As A semi-permeable material, Aquabar “B” is much less likely than common poly film to trap moisture condensation between it and the sub-floor. With a moisture vapor permeance of less than 1, Aquabar “B” is a superior vapor retarder under wood flooring applications.
