Description Aluminum Foil Radiant Barrier for saunas cover 48″ wide and will cover a total of 275 square feet. This roll has enough aluminum foil to cover a sauna room measuring 7′ x 7′. Polyethylene, while an excellent vapor barrier, will break down and melt in the ceiling or in the area around the heater as it does not have a high temperature rating. The aluminum foil has the required high temperature rating. It is also an extra insulator as it reflects heat back into the sauna room. An installation note: The shiny side must face inwards to the sauna; trim off the excess foil at the bottom with a trimming knife and mark the edges of all nailing studs with a grease pencil (or by creasing the foil with your fingernail). By marking all of the nailing areas (including benches), you will simplify the job of nailing on the T & G cedar lining. Please Note: Our vapour barrier is not paperback vapour barrier Please note for USA customers that because of the removal of “De minimus” tax law this product may be subject to duty (effective August 29th) all Homecraft Heaters, controls & wood are exempt as USMCA compliant goods
