VWFAXW Series Window Sealing Tape is a high-performance butyl flashing tape designed for sealing the exterior perimeter of windows and doors within the building envelope. It helps protect rough openings from water intrusion and air leakage, creating a continuous and durable weather barrier around critical window and door details.
With strong waterproofing, airtightness, and excellent conformability, VWFAXW is suitable for North American window flashing applications where reliable sealing around complex gaps, corners, and frame transitions is required.
