CertainTeed's MemBrain™ Continuous Air Barrier & Smart Vapor Retarder is a vapor retarder sheeting intended for use with unfaced, vapor-permeable mass insulation (fiberglass and mineral wool) in wall and ceiling cavities. It changes its permeability with ambient humidity conditions, all while providing a continuous air seal.
- Continuous indoor air barrier creates a better performing building envelope
- Dynamic performance and permeance rating
- Senses and adapts permeance to varying humidity throughout the year to keep the cavity dry
- Prevents moisture vapor from entering the wall cavity in the winter
- Allows any moisture buildup to escape the cavity in the summer
- When installed with standard tape and sealing practices, creates an air barrier that has been tested under stringent performance guidelines
