Darkening of the sauna room walls
Over time, the wooden materials used in the sauna room may begin to darken due to
the high temperature. This is a natural process that does not pose a risk and is usually
caused by the darkening of the wood protection product used. The darkening process
can also be caused by the fine stone dust, breaking away from the heater stones and
lifted up by the airflow. By following the manufacturer's instructions when installing the
heater, flammable materials in the sauna room will not become dangerously hot.
ATTENTION! The highest allowed temperature for the wall and ceiling surfaces of
the sauna room is 140˚C.
Floor of the sauna room
Due to large changes in temperature, the heater stones also crumble over time.
Together with the steam water, particles released from the stones and fine stone dust
are washed onto the sauna floor. Hot stone chips can damage plastic covered floors
under and near the heater. The splashes of heating stones and steam water
(especially for e.g. iron-rich water) can be absorbed into the light joint of the tile floor.
In order to avoid aesthetic damage, ceramic tiles and dark joint filler should be used
under and around the heater.
Ventilation of the sauna
In order to ensure sufficient oxygen supply and fresh air, the sauna's ventilation should
be as efficient as possible (air should exchange six times an hour).
The ventilation system depends on whether the building has a natural air inlet and outlet
or forced ventilation.
Sauna ventilation consists of at least two, as a rule three parts:
• Supply air pipe. The supply air pipe diameter should be ∅ 50-100mm.
• Exhaust air pipe. The diameter of the exhaust air pipe should be 2x the
diameter of the supply air pipe, ∅ 100-200mm.
• Drying pipe. In the absence of a drying pipe opening, the door may be left open
for ventilation after using the sauna.
