Applications

CONSTIVAP PLUS^® is a high performance, class 2 vapor retarder and air barrier. It's reinforced for dense-pack insulation and helps protect assemblies where a vapor retarder is needed, with a perm rating of 0.17.

Advantages

• Vapor retarding membrane with best in class strength for dense-packing fibrous/vapor open thermal insulation
• Offers insulated assemblies protection against damages and mold from diffusion and air leakage
• Durable airtight layer, with good surface tension for optimal tape adhesion
• Very minimal bulging when used as dense-pack membrane because of reinforcement grid
• Suitable for all types of batts (unfaced fiberglass, mineral wool, cotton, sheeps wool, hemp, flax, etc), as well as for all types of insulation boards (wood fiber, mineral wool, glass wool, straw, etc)
