DAFA universal pipe collar

DAFA universal pipe collars are part of the DAFA AirStop System and are a patented solution for sealing the vapor barrier around pipe penetrations. They can be attached directly to the vapor barrier—quickly, simply, and securely.

Material

The product consists of a black, soft, and flexible EPDM membrane coated with a very strong acrylic adhesive. The adhesive has been specially developed for sealing and laminating PE and PP vapor barriers. The Danish Technological Institute tested the product. The 1.2 mm thick EPDM membrane comes with pre-stamped markings.
