Description
Description

CertainTeed's MemBrain™ Continuous Air Barrier & Smart Vapor Retarder is a vapor retarder sheeting intended for use with unfaced, vapor-permeable mass insulation (fiber glass and mineral wool) in wall and ceiling cavities.

Features
  • Remains tight in winter when humidity in the cavity is low to prevent moisture from entering
  • Increases permeability in summer to let moisture escape, helping to keep the wall dry
  • Continuous indoor air barrier creates a better performing building envelope
  • Dynamic performance and permeance rating compared to traditional kraft insulation or polyethylene sheeting
  • Senses and adapts permeance to varying humidity throughout the year to keep the cavity dry
  • When installed with standard tape and sealing practices, creates an air barrier that has been tested under stringent performance guidelines
Code: CER409749
