Product data

To ensure the air and wind-tightness of a building’s shell the membranes or sheeting materials used must be permanently sealed at overlaps, gaps, joins and penetrations areas. AIRSTOP FLEX FEE Adhesive Tape is flexible, tear-resistant, can be plastered over and painted over and has a high adhesive content with a highperformance adhesive. The adhesive tape’s backing with separate liners means that the tape is particularly suitable for adhesion at corners, intersections and for window installation conforming to RAL and ÖNORM B 5320.
