MemBrain Smart Vapor Retarder breathes to allow excess moisture to escape from wall cavities, preventing mold growth and contributing to comfortable, healthy indoor air.
The product is constructed out of a polyamide film that changes permeability from less than one perm at low humidity to greater than 20 perms at high relative humidity.
