Air and Vapor Barrier Membranes and Accessories

Air and Vapor Barriers play a critical role in controlling the movement of air and vapor through the wall assemblies of a building. Selecting the proper air and vapor barrier systems to meet the needs of a building’s internal and external environmental conditions will not only provide the building with healthy indoor air quality, but it will also minimize the damage that comes from mold, mildew, and corrosion, and play a critical role in the energy efficiency of your building.

Polyglass’ range of Air and Vapor Barrier products includes Permeable and Non-permeable sheet and fluid-applied membranes, sealants, liquid flashings, and detailing tapes that are fully compatible, providing you the protection that you need for your building.

With the introduction of the VertiWrap™ line, Polyglass is your single-source provider of products from roof to wall to foundation. Seal the Envelope™ with best-in-class products designed to protect you from the unpredictable.
