 Basic Use
CertainTeed MemBrain™ 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.

This product can be used in place of traditional vapor retarders with unfaced fiber glass insulation to provide an insulation system that is ideal in some of the more severe climate condition areas in terms of both temperature and humidity.

 Basic Use
This product is intended for use in either residential or commercial construction as thermal and acoustical insulation in walls. These batts are designed for use in standard width wood framed construction where a vapor retarder is needed. The batts have kraft-paper facing without flanges and can be friction-fit between wall studs for non-exposed applications.
