A vapour control barrier for use in warm roof systems.
An edge reinforced laminate of a specially modified asphalt supported with twin layers of reinforcing kraft paper.
Similar to the standard Permate except an additional, highly impermeable film of aluminium foil is sandwiched between the twin layers of asphalt and kraft. The asphalt-kraft skin reinforces the foil and protects it from nicks and scratches during application.
Superior insulation protection: Insulation retains its full insulating value and will not be subject to moisture induced rot or warping
Fire resistance: Permate vapour retarders limit combustibles and reduce flame spread in a roofing system
Tear and puncture resistant: Vapour retarder edges are reinforced with glass fibre strands to help prevent tears during application. In Permate Ultra, the twin layers of asphalt bonded kraft protect the aluminium foil from nicks and scratches during application
Compatibility with virtually all types of roofing systems. They are not affected by contact with either asphalt or single-ply system adhesives
Wide rolls for rapid, cost efficient installation
Proven performance, protecting thousands of buildings across North America and Europe for over twenty-five years
F.M. & U.L.C. approved
