CCW-705 Air & Vapor Barrier is a 40-mil-thick (0.040" inch) composite membrane consisting of a rubberized-asphalt adhesive laminated to a tough, dimensionally stable, smooth-surfaced poly film. CCW-705 is provided in rolls of various widths lined with disposable silicone-coated plastic release film. The release film is removed to expose the adhesive as the membrane is pressed in place. CCW-705 provides a complete barrier to moisture and air when adhered to an above-grade substrate. Cut sizes are also useful for other above-grade wall flashing applications. CCW-705 is cold applied and will adhere firmly when pressed against the substrate.
