Hi
I'm in the process of renovating a part of the house that is original from the 50s. I imagine I should tear down a lot of the exterior walls to start over with new insulation and vapor barrier.
But I would need some input and tips on how the wall may be constructed. I can't quite make sense of the measurements and materials I find.
What I think is as follows from inside out?
Tretex-rough boards-styrofoam with some paper surface-chipboard-building paper-brick.
Thickness about 9 cm excluding tretex
I have torn down the tretex (slightly unpleasant smell) and plan to remove the rough boards and styrofoam, but the question is whether I should take everything while I'm at it?
I would gratefully receive some tips and ideas.

The plank wall in the picture might be stabilizing in such an old house. You should not take it down without being sure that the stability is not affected.

Then everything old stays, I'll build on with a 45mm stud + gypsum with wood fiber insulation and vapor brake (not diffusion-tight plastic). Then I can also run new electricity in that compartment. What do the recommendations say then, vapor brake directly under the gypsum or on the old plank wall?
After some analysis and searches, I conclude that the "frigolite" is not frigolite but urea foam, popular in the 60s.
As I wrote, I'm leaning towards letting the existing material remain and adding a 45: +gypsum. Does anyone with experience with urea foam have a different opinion? I have read the threads available on the subject, and as usual, opinions are divided.
