Hello everyone,
Since my parents are a bit hesitant to consult an expert and I don’t really have much knowledge on this topic, I’m just going to ask you all—maybe someone knows something 🙂
My parents have been planning for some time to build an extension to their private home and install a sauna in this extension. Now, a sauna exposes the walls to a significantly different type of moisture than a regular bathroom (it’s warmer, of course) – how is the best way to insulate the walls to prevent mold from forming on the inside?
I’ve tried to read up on this via Google, but I haven’t really found a clear answer 🙁 For individual products like mortar, plaster, concrete, etc., there is always mention of capillary water absorption/water absorption coefficient and something about water vapor – but I don’t really understand what that means or whether a high or low value is good or bad.
Logic tells me that exposure of a wall to moisture and air will lead to mold over time, but maybe it works in a completely different way...
I also asked about this once at a home improvement store, but the salesperson looked at me as if I was crazy...
Could someone please explain this to me? :/

The conditions have changed over the years, as have the materials. Newly constructed buildings or extensions are much more airtight than older buildings.
For this reason, lime-cement plaster is still applied in bathrooms, even though it involves additional effort (both labor and costs) compared to gypsum plaster. This is the case despite exhaust air systems or ventilation units. 😉

EveundGerd16 Apr 2015 12:50Since we still use the public sauna at the moment, I cannot provide a final opinion on that.
We will install an infrared heat cabin.
The neighbor has a sauna in her bathroom. The walls are covered with the plaster I previously recommended. In addition, there are two large floor-to-ceiling windows for cross-ventilation.
She regularly uses these windows for ventilation after every sauna session.

Ah, okay, ^^ I had overlooked that one side.
