H&B X-Seal Transition Membrane - 75' Roll
H&B X-Seal Transition Membrane Features
This transition membrane ensures a smooth, flexible seal in areas where different building materials meet, such as beams, columns, and joints. It is designed for use with Enviro-Barrier™ air and vapor barrier systems, providing continuity and protection across transitions. The membrane is adhesive-backed with a removable release liner for easy installation. Manufactured from 45% post-industrial and post-consumer recycled material, it meets industry sustainability standards while maintaining high durability. It withstands extreme conditions, achieving a tensile strength of up to 130 lbs and a tear strength of 46 lbs (ASTM testing).
- Self-sealing and self-adhering transition membrane for air and vapor barrier continuity.
- Designed for use with the ENVIRO-BARRIER™ system to seal joints, seams, doors, and windows.
- Heavy-duty synthetic rubber adhesive bonded to a reinforced polyethylene/polypropylene film.
- Resistant to rot, cracking, and adhesive drooling, ensuring long-term durability.
- UV-resistant for up to 120 days, making it suitable for extended construction timelines.
- Asphalt-free composition enhances compatibility with various substrates and sealants.
- Available in widths from 3” to 36” (custom sizes up to 72” available upon request).
- Each roll is 75 feet in length, providing extensive coverage.
- Manufactured from 45% post-industrial and post-consumer recycled material.
- High tensile strength (130 lbs) and tear resistance (46 lbs), tested to ASTM standards.
- Compatible with various building materials, including CMU, OSB, plywood, and glass-faced sheathing.
