Butyl Stretch Flex Tape

Butyl Stretch Flex is used particularly as a seal at penetration points through air-tight vapour control layers, roof/facade membranes, OSB and plywoods. Due to its great flexibility the tape can be positioned easily around any size opening that requires sealing. Its extremely good adhesive properties allows it to work on a variety of substrates, mostly without a primer. Its malleability allows it to be neatly pressed down, sealing any form or shape.
