Comes in a 54" wide roll. However our sq ft figures below are based on a 48" roll, so your overlap is taken care of! Aluminum foil sauna vapor barrier is one of the necessary components for traditional sauna room construction. We use foil in all the saunas we manufacture. Do NOT use other vapor barrier materials, such as plastic, Visqueen or Tivek. They melt and/or release an unpleasant odor.
