The walls must "breathe" or not?
Answer from: ~Red~ (Anton Maltsev):
I know a lot about paintball and like to learn new and interesting!...
All walls are permeable to air and water vapor.
If the term "breathable walls" means that they participate in the process of air exchange in the room, it is not. Less than 1% of the air passes through the walls, and fresh air in the room can only come from good ventilation.
If by that term you mean no condensation on the inside surface of the envelope, that's not true either. There is no condensation on a properly designed fence at all, because it is against the current building code.
Therefore walls must not breathe.
