Hello, I was at a friend's house who just bought a house where the garage area had water damage. When I looked a bit at the repairs the construction company did, I noticed they hadn't addressed the walls. When I removed the insulation, I saw that on the outside of the stud (the outer wall) there were plywood boards that were slightly black. I told my friend that it wasn't optimal since he planned to build a room in one part of the garage and intended to keep it around 25 degrees in that room. I said that the condensation inside the wall wouldn't be able to escape. My friend said it was a Myresjöhus and they build according to standards so it's built correctly. So my question to those of you who know better than me at a hobby level, is it correct to build like that? I believe there's a high risk that mold will develop inside the wall. I have a cross-section image of the wall. Looking forward to a healthy discussion in this thread.
