Description


Perm-A-Barrier Wall Membranes are ideal for protecting the building superstructure from the damaging effects of the elements. By minimizing air and water vapor flow through the building exterior, Perm-A-Barrier Wall Membranes


Features


  • Fully bonded - transmits wind loads directly to the substrate
  • Prevent premature deterioration of the building envelope
  • Improve comfort for the building occupants
  • Flexible accommodates minor settlement and shrinkage movement
  • Waterproof and impermeable to moisture impermeable to the passage of liquid water and water vapor
  • Waterproof and impermeable to moisture - impermeable to the passage of liquid water and water vapor
  • Enhance thermal performance of the structure and save energy costs
  • Aggressive, conformable adhesive creates 100% watertight laps and allows self-sealing around mechanical fasteners
  • Cross laminated film provides dimensional stability, high tear strength, puncture and impact resistance
  • Air tight - exceeds CCMC requirements for air barrier membranes, complies with massachusetts state energy code and meets new ASTM E2357 standard
  • Cold applied - no flame hazard; self-adhesive overlaps ensure continuity
  • Controlled thickness factory made sheet ensures constant, non-variable site application
  • Fully bonded continuous adhesion to the substrate resists wind loads and prevents water tracking behind the tape
  • 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
  • Aggressive, conformable adhesive - allows self-sealing around mechanical fasteners
  • Cross laminated film - provides dimensional stability, high tear strength, puncture and impact resistance
  • Controlled thickness - Factory made sheet ensures constant, non-variable site application
  • Flexible - accommodates minor settlement and shrinkage movement
  • Unique green color and logo highly differentiated on the job site from other flashing types and enables easy identification of damage
