Bi-Tec UDL-40 Underlayment SBS - 2 Sq. Roll
SKU: 283150
BITEC UDL-40 premium underlayment is a monolithic SBS compound, reinforced with a high-strength fiberglass mat. The SBS compound offers a flexible and pliable product which will lay down flat during application, making it easy to install. It has greater tear resistance as compared to conventional organic felt based underlayments and oxidized fiberglass products. The top layer is mineral surfaced for extra toughness, and the bottom layer has polyethylene film as a vapor retarder.
