DAFA Hi-tack® universal pipe collar
DAFA Hi-tack universal pipe collars are part of the DAFA AirStop System and are a patented solution used for sealing the vapor barrier around pipe penetrations. Attach the collar directly to the vapor barrier – quickly, simply and securely.
The product consists of black, soft and flexible EPDM membrane coated with a very strong acrylic adhesive. The adhesive has been specially developed for sealing and laminating DAFA HiFoil and DAFA ExFoil vapor barriers. The 1.2 mm thick EPDM membrane comes with pre-stamped markings.
The DAFA Hi-tack pipe collar is included in the Nordic Ecolabellings database of construction products that can be used in Swan-labelled buildings.
