Type C Single Sided Foil Vapor Barrier

This is a superior radiant and vapor barrier used for sauna construction or other building applications. When building your sauna, it is important to install this vapor barrier under the tongue and groove wall boards to increase the R-value, radiate heat back into the sauna, and add extra protection from sauna moisture.

Once you frame and insulate your sauna walls, simply staple this product to the studs, prior to installing your tongue and groove wood. For the best protection, be sure to make as few cuts as possible and always overlap adjoining runs by 2″ – 3″. This roll is 3.28′ x 82.02′ (269 s.f.). It will cover up to a 6′ x 8′ x 7′ sauna.

NOTE: For an even better installation tape the seams using a roll of “Tough Tape” in related products below. One roll is generally enough for a roll of foil.
