The aluminum foil vapor barrier is an important component for your sauna. Once installed it reflects heat back in to the sauna while protecting the structure by not letting moisture be absorbed in to the outer structure. Plastic Vapor barriers will melt in the high heat of the sauna. Install foil so that it overlaps on studs, and secure with wood staples. Foil Tape or red Tuck Tape can be used to repair tears if necessary (Not Provided).
