GCP PERM-A-BARRIER® Detail Membrane 6” x 75' Roll

PERM-A-BARRIER® Detail Membrane is ideal for protecting and sealing critical areas of the building superstructure from the damaging effects of the elements. By minimizing air and water vapor flow through the building exterior at transition areas, PERM-A-BARRIER® Detail Membrane:

• Seals transition and detail areas to provide a continuous air barrier
• Prevents premature deterioration of the building envelope

Product Advantages:

• Fully bonded - transmits wind loads directly to the substrate
• Waterproof and impermeable to moisture - impermeable to the passage of liquid water and water vapor
• Airtight - exceeds CCMC requirements for air barrier membranes, complies with Massachusetts State Energy Code
• Cross-laminated film - provides dimensional stability, high tear strength, puncture and impact resistance
• Cold applied - no flame hazard; self-adhesive overlaps ensure continuity
• Flexible - accommodates minor settlement and shrinkage movement
• Controlled thickness - factory-made sheet ensures constant, non-variable site application
• Aggressive, conformable adhesive - allows self-sealing around mechanical fasteners 
• Wide application window - PERM-A-BARRIER® Detail Membrane surface and ambient temperatures at 25°F (-4°C) and above
