With an extra thick HDPE layer than most other GCP flashings for protection of the waterproof membrane, Perm-A-Barrier® Wall Flashing is the ideal Wall Flashing for heavy-duty masonry applications. Ideal for both new and retrofit applications, Perm-A-Barrier® Wall Flashing is a 40-mil through wall membrane designed to collect water entering wall cavities and direct it to the exterior through the wall's weep system. Its unique green color and repeated imprinted logo quickly differentiate it on the jobsite from other flashing types. Easy to install, Perm-A-Barrier® can be applied to concrete, masonry, block, steel, gypsum and wood and is highly effective even on vertical surfaces and around details. Available in 83.3' rolls in widths of 12", 18"


  • Fully bonded — continuous adhesion to the substrate resists wind loads and prevents water tracking behind the tape
  • Waterproof and virtually impermeable to moisture — virtually impermeable to the passage of liquid water and vapour
  • 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 — creates 100% watertight laps and allows self-sealing around mechanical fasteners
  • Unique green color and logo — highly differentiated on the job site from other flashing types and enables easy identification of damage
  • Ripcord® Split Release on Demand — faster application in the straight-aways, ease of membrane positioning in detailed areas
  • Foldless release paper — fewer edge catches, 180° pull-back, ease of membrane cutting (single cuts) and membrane positioning, quicker one-man installs
