  • 20 MIL SELF-ADHERING BUTYL FLASHING MEMBRANE – BT20XL is a cold-applied, self-adhering flashing membrane composed of a tough cross-laminated high-density polyethylene film laminated to a proprietary butyl adhesive layer for exterior sealing applications.
  • DESIGNED TO SEAL EXTERIOR SHEATHING JOINTS – This butyl flashing tape helps seal joints in exterior sheathing and is engineered to integrate with window and door installations as part of a complete building envelope moisture management system.
  • FLASHING FOR WINDOW AND DOOR NAILING FLANGES – Self-adhered flashing helps seal window and door nailing fins, supporting water management around rough openings when installed according to standard flashing practices.
  • 120-DAY UV EXPOSURE RATING FOR JOBSITE FLEXIBILITY – Rated for up to 120 days of UV exposure, this flashing membrane supports phased construction schedules and exterior exposure prior to final cladding installation.
  • EASY PEEL-AND-STICK INSTALLATION METHOD – Cut BT20XL flashing membrane to the required length, remove the release liner, and apply to a clean, dry surface. Press firmly along exterior sheathing joints or window and door nailing flanges to ensure proper adhesion and water management.
