Black Jack® Floating Floor Cushion Underlayment is a dense foam underlayment that helps absorb everyday in-room noise under floating laminate, bamboo and engineered flooring. The 2.5 mm thick foam layer provides optimal cushioning and sound absorption, and is ideal for use with radiant-heated floors. The closed-cell design provides excellent moisture-vapor resistance, and helps fight mold and mildew. For added convenience and time savings, Black Jack features a 3" overlap and adhesive strip to join pieces and help seal out moisture.
