Perm-A-Barrier® Aluminum Flashing

Perm-A-Barrier® Aluminum Flashing is ideal for protecting and sealing critical areas of the building superstructure from the damaging effects of the elements. Perm-A-Barrier Aluminum Flashing’s aluminum faced film provides extended UV exposure, improved sealant adhesion to film, dimensional stability, high tear strength, puncture and impact resistance. By minimizing air and water vapour flow through the building exterior at transition areas, Perm-A-Barrier Aluminum Flashing seals transition and detail areas to provide a continuous air barrier.

FEATURES AND BENEFITS

MORE FEATURES AND BENEFITS:
  • Fully bonded — transmits wind loads directly to the substrate
  • Waterproof and impermeable to moisture — impermeable to the passage of liquid water and water vapour
  • 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 application
  • Aggressive, conformable adhesive — allows self-sealing around mechanical fasteners
