2. THE SAUNA ROOM
2.1. Insulation and Wall Materials of the
Sauna Room
In an electrically heated sauna, all the massive wall
surfaces which store plenty of heat (such as bricks,
glass blocks, plaster etc.), must be sufficiently insu-
lated in order to keep the heater output at a reasonably
low level.
A wall and ceiling construction can be considered
to have efficient thermal insulation if:
the thickness of carefully fitted insulating wool
•
inside the house is 4" (100 mm) minimum 2"
•
(50 mm).
the moisture protection consists of e.g.
•
aluminium paper with tightly taped edges. The
paper must be fitted so that the glossy side is
towards the inside of the sauna.
there is a 3/8" (10 mm) vent gap between
•
the moisture protection and panel boards
(recommendation).
the inside is covered by 1/2" – 5/8" (12–16
•
mm) thick panelling.
there is a vent gap of a few millimetres at the
•
top of the wall covering at the edge of the ceiling
panelling.
When aiming at a reasonable heater output, it may be
advisable to lower the ceiling of the sauna, (minimum
height 6'7" (2010 mm)). As a result, the volume of the
sauna is decreased, and a smaller heater output may
be sufficient. The ceiling can be lowered so that the
ceiling joists are fixed at a suitable height. The spaces
between the joists are insulated (minimum insulation 4"
(100 mm)) and surfaced as described above.
Because heat goes up wards, a maximum distance
of 47" (1200 mm) is recom mended between the
bench and ceiling.
NOTE! Consult fire extinguis hing authorities to find
out which part of the fireproof wall may be insulated.
NOTE! The protection of the walls or ceiling with
heat protection, such as mineral board fitted directly
on the wall or ceiling, may cause the temperature
of the wall and ceiling materials to rise dangerously
high.
Room construction – general information
FRAMING
2" x 4" any suitable wood
material, 16" o.c.
CEILING HEIGHT No higher than 7' 0".
INSULATION
R11 Fiberglas with foil back in
walls and ceiling, foil facing into
room.
DRYWALL
See local codes. Is not required
in most residences. See local
codes for commercial. If drywall
is usedapply 1" x 2" nailers so
that wall and ceiling boards can
be attached to solid wood.
PANELING
Use kiln-dried, clear, T & G soft-
wood such as California Redwood,
Western Red Cedar, Alaska Yellow
Cedar, pine, spruce or other suitable
wood material (with moisture
content not exceeding 11 %).
BENCHES
Use matching wood of vertical
grain. Fasten from bottom to
prevent burning of bathers.
HEATER
Use matching softwood.
GUARDRAIL
DOOR
Must open out and should not
have a lock.
ROOM LIGHT
Should be a vapor proof, wall
mounted type, with rough-in box
munted flush with inside paneling.
It should mount 6" (150 mm) from
ceiling, not directly over
Sauna heater, and not over upper
benches; light bulb should not
exceed 75 watts.
Note! Receptacles OR PLUGS are not allowed in a
Sauna room. If a speaker is installed in a Sauna room,
it should not be installed higher than 3' from floor,
away from the Sauna heater (consult manufacturer
for ratings).
2.2. Sauna Room Floor
Due to a large variation in temperature, the sauna
stones disintegrate in use.
Small pieces of stone are washed down on the
sauna room floor along with the water thrown on the
rocks. Hot pieces of stone may damage plastic floor
coverings installed underneath and near the heater.
A light-cocoured joint grout, used for a tiled floor,
may absorb impurities from the rocks and water (e.g
iron content).
To prevent aesthetic damage (due to the reasons
presented above) only dark joint grouts and floor
coverings made of rock materials should be used
underneat and near the heater.
2.3. Heater Output
When the walls and ceiling are covered with panels,
and the insulation behind the panels is sufficient to
prevent thermal flow into the wall materials, the
heater output is defined according to the cubic vol-
ume of the sauna. See table 1.
If the sauna has visible uninsulated wall surfaces,
such as walls covered with brick, glass block, con-
crete or tile, each 10 square feet (ca. 0,1m²) of said
wall surface causes the cubic volume of the sauna
to increase by 1,2 Cu.Ft. (ca. 0,12 m
output is then selected according to the values given
in the table.
Because log walls are heated slowly, the cubic
volume of a log sauna should be multiplied by 1.5,
and the heater output should then be selected on
the basis of this information.
2.4. Hygienic Conditions of the Sauna Room
Good hygienic standards of the sauna room will
make bathing a pleasant experience.
The use of sauna seat towels is recommended to
prevent sweat from flowing onto the platforms. The
towels should be washed after each use. Separate
towels should be provided for guests.
It is advisable to vacuum or sweep the floor of the
sauna room in connection with cleaning. In addition,
the floor may be wiped with a damp cloth.
The sauna room should be thoroughly washed at
least every six months. Brush the walls, platforms
and floor by using a scrubbing-brush and sauna
cleanser.
Wipe dust and dirt from the heater with a damp
cloth.
