Air Ventilation

To have a soothing sauna, there should be a proper mixing of hot and cold air

inside the sauna room. Another reason for ventilation is to draw air around the

heater and move the heat to the farthest part of the sauna. The positioning of

the inlet and outlet vents may vary depending on the design of the sauna

room or preference of the owner.

The inlet vent may be installed on the wall directly below the heater (Fig. 7a).

When using the mechanical ventilation, the inlet vent may be placed at least

60 cm above the heater (Fig 7b) or on the ceiling above the heater (Fig. 7c).

Through these positions, the heavy cold air that is blown into the sauna is

mixed with the light hot air from the heater, bringing fresh air for the bathers

to breathe. The recommended size for the inlet vent is 5-10 cm.

The outlet vent should be placed diagonally opposite to the inlet. It is

recommended that the outlet vent be placed under the platform in a sauna as

far as possible from the fresh air vent. It may be installed near the floor, or led

outside through a pipe from the floor going to a vent to the sauna ceiling, or

under the door (to the washroom). In this case, the sill slot must be at least 5

cm and it is recommended that there is mechanical ventilation in the

washroom. The size of the exhaust should be twice that of the inlet.

Insulation

The sauna must have proper insulation on the walls, ceiling and door. One

square meter (m²) of un-insulated surface increases the cubic volume by

approximately 1.2m³ when determining the power requirement of the heater.

Refer to page 20 (Technical Data).

Ensure that moisture proofing is appropriate in the sauna room. The purpose

of this is to prevent spreading of moisture to the other rooms or wall

structure. Moisture proofing must be placed between heating insulation and

panel.

Thermal and moisture proofing need to be installed according to the following

order from outside to inside.
