AIR CONVECTION AND RENOVATION SYSTEM
As can be seen in this figuer, when the sauna is in use, a thermal
progression is produced in the interior. This progression is due to the fact
that the air is lighter as the temperature increases. At the same time, the
system allows for a continuous renovation of the air, maintaining the high
temperature in the interior of the sauna.

BASIC SAUNA MATERIALS AND COMPONENTS
The materials used in the manufacturing process of the sauna largely
determine its proper operation and the funcations and options expected.
Just as with any other porduct, it is valued for its quality and optimum
results during use; the manufacturing components of a Finnish sauna must
comply with a series of qualitative requirements.
Because of this, in the following lines the materials used in the manufacture
of the sauna are oultined, as well as the criterias used in their selection.
The wood: It is the principal raw material used in the manufacture of the
sauna, and the characteristics of this material, along with the manufacturing
and anchoring system, figure prominently in the sauna's quality.
The sauna incorporates different types of wood in its manufacture and each
of them must comply with the concrete requirements for its functions.
