Hello,
I have a house from the 40s with knee wall panels. I decided to tear down one of them. I brought a support beam with me and also made a small hole in the floor underneath to see if the wall rested on the roof truss or the floor joist below. It didn't, so I began removing one plank at a time (the wall consisted of tongue and groove planks 200x50 mm.) and moved the support beam with me. I also took a measurement from the roof truss down to the floor which I checked remained the same the entire time. It did. Also, a rather large amount of snow fell on the roof the next day, and the measurement was the same. The plank with the electrical outlet will stay until the electrician comes to move it.
Then it was time for insulation. I have read a lot about vapor barriers and double insulation and such, but since it's an old house I decided to go with a simple air gap of 45 mm, and a single insulation with 45 mm mineral wool, followed by an OSB board and gypsum (I haven't gotten to the gypsum yet).
What do you think, is this correctly executed so far?
Can I apply the same method to the remaining knee wall panels?

There stood 1 meter high support legs for the roof trusses, with only the eaves behind them, without any insulation. Therefore, I chose to do a simple insulation after the air gap, to "mimic" the old solution.
