PERM-A-BARRIER ALUMINUM FLASHING - Self-adhesive,rubberized asphalt detail membrane for air and vapor barrier purposes
Perm-A-Barrier Aluminum Flashing 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 Aluminum Flashing seals transition and detail areas to provide a continuous air barrier. It also prevents premature deterioration of the building envelope.
- Fully bonded—transmits wind loads directly to the substrate
- Waterproof and impermeable to moisture—impermeable to the passage of liquid water and water vapor
- Aluminum faced film—provides extended UV exposure, improved sealant adhesion to film, 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 condition
- Aggressive, conformable adhesive— allows self-sealing around mechanical fasteners
- Wide window—Perm-A-Barrier Aluminum Flashing surface and ambient temperatures at 25°F (-4°C) and above.
