Environmental protection and energy efficiency also play a central role in sauna construction, and we apply strict quality standards in our choice of wood and its processing, as well as in the operation of the sauna itself. The insulated cabin shell with its sophisticated, multi-layer construction reduces energy consumption, for example, because it stores heat and releases it evenly into the interior. At the same time, we reduce the heat-up time inside the sauna by means of efficient heater technology and, under certain circumstances, we can even feed the waste heat into the ventilation system of Minergie®-certified houses.
