In protecting your interior space from outside air and vapor transmission, CCW offers three
distinct product catagories providing a “Single System Solution.” CCW's Air & Vapor Barriers are asphalt-based sheet,
spray-applied membranes and multi-layered geomembranes that provide the convenience of quick application and the
lasting benefits of using quality materials. The Air & Vapor Barrier Systems consist of CCW-705 fully-adhered
sheeting, Barriseal fluid-applied membrane, and CCW 705-TWF Thru-Wall Flashing. Barriseal, a water-based asphalt
emulsion, provides a spray-applied medium for large-scale jobs and difficult-to-seal substrates.
