Round Cedar Sauna Air Ventilation Louver
Air circulation vents allow fresh air into the sauna for comfortable breathing and to help maintain a healthy sauna. Sauna ventilation systems consist of an intake and an exhaust vent. Our sauna vent designs are made with Cedar wood or White Aspen to match a variety of T&G wall paneling types. It is recommended that both vents utilize the same airspace, either outside or to the same room or other interior space.
Sauna ventilation requirements call for two vents, one lower vent for fresh air intake (or gap under entrance door) and one upper vent for exhaust (about one-third up the opposite wall to minimize heat loss). The leading cause of bacteria growth, mold and malodorous saunas is poor air ventilation during steam sauna use and after during the cool down period. The vent is 6" across and requires a rough opening of 3 5/8"
Outdoor sauna buildings with a wood burning stove can be challenging to properly vent, as the stove needs more fresh air than an electric stove. The exhaust vent can be regular size, however the intake vent should be approximately twice the size and near the wood stove. If you have a dividing wall to separate a changing room, it is recommended to install another set of intake and exhaust vents in the changing room, which should typically be opened after the sauna is used to help evaporate any condensation.
