Today, I have a gable on my upper floor made up of the outermost roof truss, with various studs in place to hold an old rotten window. On the outside, there is wind protection, battens, and paneling. The wall is uninsulated and consists only of the studs.
What I want to do now is to furnish my upper floor and therefore insulate both the spaces between the roof trusses and the wall. I was thinking that the wall should be 170 mm.
Now to the question. What should I do first, insulate the sloped roof or the wall? If I insulate the sloped roof first, it will be tricky to put my 170 mm studs on the gable against the already insulated roof. On the other hand, if I start by tearing down the outer wall to reframe it, I will somehow have to notch out the studs to connect to the outermost roof truss?
Can anyone understand my problem and give me tips on how to solve it?
Thanks in advance!!
