6. AIR EXCHANGE FOR THE STEAM ROOM:
- The air exchange in the steam room must be as efficient as possible, in order to
guarantee sufficient oxygen content and availability of fresh air. The air in the steam room
should be changed 3-6 times in an hour.
It is recommended that the ventilation be realised in accordance with the HVAC designer’s plan
- The fresh air is directed through a ca. 100-mm diameter duct. The outlet duct should be larger
in diameter than the inlet duct. If the ventilation is mechanical, we recommend placing the inlet
air valve in the ceiling near the heater. Locate the temperature sensor at a sufficient distance
from the inlet air valve!
- There must be a space of at least 1,000 mm between the temperature sensor and
the fresh air duct or 500 mm if the duct end can be turned.
- If the ventilation is natural, we recommend placing the inlet air valve on the side of the heater
or under it, either in the wall or in the floor.
- It is important to introduce fresh air, so that the air mixes with the air and the steam.
- The exiting air should be exhausted from near the floor as far as possible from the incoming air.
- The air exhaust valve may be located under the sauna benches.
- The exiting air may be directed out of the steam room through the washroom,
for instance under the door. There must be an approximately 100-150-wide slit
between the door and the floor.
- If you provide your sauna with a separate drying valve, place it in the ceiling of the steam room.
(This valve shall be closed during the use of the sauna.)
7. CONSTRUCTION OF THE STEAM ROOM:
- The steam room must be well insulated, especially the ceiling, through which most of the steam
escapes. Because of the humidity, it is recommended the insulation be covered with a moisture
resistant material, for instance aluminum foil. The surface (panels) of the sauna rooms interior should
always be wooden or made of non-combustible material.
- Floor is recommended to be of dark color, because water impurity and stones may stain lighter floor
materials.
8. PROTECTIVE BARRIER:
- A protective barrier may be built around the heater if necessary. In this case, you should
definitely adhere to the minimum clearances from structures made of flammable materials.
