CCW-705 Air & Vapor Barrier is a composite membrane consisting of a rubberized-asphalt adhesive laminated to a dimensionally stable, tough, smooth-surfaced poly film. It 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. It 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.
