Roberts AirGuard 5-in-1 Premium Underlayment is the only underlayment manufactured with both Microban and air flow technology to inhibit mold growth. The bottom layer of clear film has tiny holes in it allowing the subfloor to breathe. Thousands of tiny polyshims act as cushioning and stabilizers to allow the air to move and flow through the underlayment, pushing the moisture vapor, inhibiting the growth of odor and stain causing bacteria, mold and mildew. With the overlap flap and tape, installation below grade, on grade or above grade is easy.
