CCW-705 HT High Temp Air & Vapor Barrier is a composite membrane consisting of a rubberized asphalt adhesive laminated to a tough cross-laminated HDPE film. Factory-controlled quality ensures uniform thickness on the job, providing an excellent air, vapor and water barrier. A siliconized release liner prevents the material from sticking together in the roll and is easily removed for installation. It is made with a high-temperature-resistant modified asphalt adhesive, suitable for use directly behind metal cladding. CCW-705 HT provides a complete barrier to moisture and air when adhered to an above-grade substrate and is also useful for other above-grade wall flashing applications. CCW-705 HT Air & Vapor Barrier is cold-applied and, when pressed against the substrate, will adhere firmly.
