Make sure that moisture proof is appropriate in sauna room. Purpose of this is to prevent spreading of moisture to
the other rooms or wall structure. Moisture proof must be placed between panel and heating insulation. Moisture and
thermal proofing should be installed from outside to inside:
1.
Recommend that the MIN thickness of the thermal insulation in the walls is 2” and in the ceiling 4”.
2.
Aluminum foil laminate can be affixed over the heating insulation as a vapor barrier.
3.
Leave at least 0.8” air slot between vapor barrier and inside panel.
4.
Leave a slot between wall panel and ceiling to prevent gathering moisture behind the panel.
Spruce wood is recommended as material of wall and ceiling.

door. It will take about an hour to reach suitable temperature in sauna room if the output of heater is proper.

The temperature that user preferred to is about 140-194℉. Too powerful heater will heat sauna room too quickly
and the temperature of stones may remain insufficient. Consequently, water thrown on the stones will run through and do
not produce sufficient vapor. On the other hand, if the heater is underpowered the heating time will be much longer.
