How decisive is the wall thickness?

The feeling of well-being in the sauna is not only influenced by the quality of the sauna oven, the infusion or the visual effect of the equipment. First and foremost, it is the types of wood used and above all the wall thickness that have a decisive effect on the climate in the sauna.

The thicker, the better

Ultimately, when talking about the sauna climate, we are talking less about temperatures and humidity and more about how the heat in the sauna is felt individually. An extremely pleasant room climate is one that is dominated by a soft radiation of the heat through the wooden surfaces in the sauna. Such a soft radiation of heat can only be achieved by thicker walls in the sauna. To do this, you have to consider the structure of the walls and ceilings in the sauna.

The wall structure - decisive for the heat radiation

With thinner wooden surfaces in the sauna, the insulating layer of aluminium foil or copper foil lies relatively close behind the wooden surface. This creates a rather hard heat radiation, which is usually perceived as very unpleasant. Signs of this are for example burning eyes or a burning sensation on the skin when touching the wooden surfaces.

Stronger wooden surfaces in the wall structure usually heat up only from the inside and return this absorbed heat to the room quite softly. This creates the room climate in the sauna cabin, which is described as soft and is perceived as more pleasant throughout. For this reason, it is worth giving priority to a thicker layer of wood in the interior when building a sauna wall. A pleasantly soft room climate is then the reward.
