Just a brainstorm ....
Wouldn't it be a good idea to build an empty "strawbale box", and inside
this box you build another box in wood (like a normal sauna).
Between these boxes you keep an open space for ventilation. Just like a
Then you have the very good insulation properties of the outside box, and
the good moisture properties of the inside box.
In the hollow wall you can possibly make a ventilation system.
