Our take on the QEP Cork Underlayment Roll

This is a 1/4-inch natural cork underlayment roll, 4 ft wide and 50 ft long, covering 200 sq. ft. It is made for ceramic tile and stone floors and adds a 22 Delta sound rating and an R-value of 0.74, so it quiets footfall and slows heat loss. Cork resists mold and mildew and works over any subfloor, glued down with ROBERTS 7250 Cork Adhesive or laid floating. It suits tile and stone installs where sound and warmth matter more than a thin, hard membrane.
