Introducing the new QEP Cork Plus Underlayment, an exclusive composite blend of 65% natural cork and 35% EVA foam. All of the EVA foam is collected from recycled shoes. The addition of the recycled EVA provides better flexibility and is less prone to breaking and tearing than traditional cork underlayments. Produced in 1/4-inch thickness, Cork Plus provides an impressive 63 IIC and 61 STC sound resistance rating when measured under ceramic tile. It is available in 200-foot rolls or 2- x 3-inch sheets.
