Product Applications

Grade AS is a semi-permeable barrier paper, which allows for moisture to slowly transfer to and from the flooring.  Since Grade AS helps to control moisture transmission, this product  can mitigate the chances of the flooring to buckle, warp, or crack due to drastic changes in moisture.

Grade AS provides separation between the sub-floor and the finished flooring.  This separation reduces the noise associated with poorly installed wood flooring.
