SAUNA ROOM
Wall materials and insulating the sauna room
In a sauna with electric heating, all massive heat accumulating wall
surfaces (brick, glass brick, rendering etc.) must be insulated to use
the electric heater with a regular output.
The following sauna wall and ceiling construction is considered
to be sufficiently insulated:
• a carefully installed insulation wool layer of 100 mm (min. 50 mm);
• the construction is damp proofed with taped aluminium paper or
other reflective material;
• there is a 10 mm air gap between the damp protection and
boarding;
•
a light wooden board that is about 12–16 mm thick has been used
for interior finishing;
• there is an air gap of at least 5 mm on the edge of the ceiling
panels at the upper part of the wall panelling.
In order to use the heater with a regular output, it would be practical
to bring the ceiling of the sauna lower (min. height of sauna room
2200 mm) so that the volume of the sauna room diminishes. The
ceiling is insulated with an insulation laer at least 100 mm thick and
boarded according to the method described above.
Wood should be used to cover internal surfaces; an exception may be
made for heat resistant walls in the vicinity of the heater.
ATTENTION!
Insulating the heat barrier has to be approved by the fire
inspector. Insulating flues in use is forbidden!
NB!
Covering the walls or floor with light protective material, for
example, mineral tiles that are installed directly on the surface of the
walls or ceiling might cause the dangerous overheating of the wall or
ceiling material.
