Moisture in homes is unavoidable, making moisture in wall cavities nearly inevitable - and dangerous if not properly addressed.  CertainTeed's MemBrain™ Continuous Air Barrier & Smart Vapor Retarder is the industry's most advanced technology to create a better performing home.

In "mixed-climate" parts of the country, where homes heat in the winter and cool in the summer, homes using traditional polyethylene vapor retarders may actually trap moisture in the cavity during the summer - raising the risk of costly moisture and mold issues, structural damage, health consequences and liability.

This patented, revolutionary solution can provide a continuous air barrier along with advanced moisture management in a single product, helping achieve Complete Comfort.  It's another reason why choosing CertainTeed means you're installing much more than trusted high-performance insulation products. You're installing confidence.

Where to Use MemBrain

Vapor retarders are required by code in zones 4C and above. However, MemBrain is ideal for any area where the home cools in the summer and heats in the winter.
