Sauna foil barrier

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
