GRADE AS – ASPHALT SATURATED KRAFT

Medium Weight Kraft Saturated with Asphalt

When Blue Shield Grade AS is used as an underlayment for wood or tile flooring it offers multiple benefits:

Moisture Protection

Grade AS is a semipermeable barrier paper. It allows for moisture to slowly transfer to and from the flooring. Helping to control moisture transmission, AS can mitigate the chances for the flooring to buckle, warp or crack due to drastic changes in moisture.

Slip Layer

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