The CCW-705 LT Air & Vapor Barrier is a composite membrane consisting of a special extra tacky, rubberized asphalt adhesive laminated to a tough, cross-laminated HDPE film which is specially formulated to enable easier installation in cold weather conditions. A siliconized release liner prevents the material from sticking together in the roll and is easily removed for installation. Factory-controlled quality ensures uniform thickness on the job, providing an excellent air vapor and water barrier. CCW-705 LT provides a complete barrier to moisture and air when adhered to an above-grade substrate. It is also useful for other above-grade wall flashing applications. It is cold-applied and will adhere firmly when pressed against the substrate.
