If I have seen correctly, my wall looks as follows:
Brick
--------
Air gap
--------
Wood/asfaboard
--------
Black tar paper
--------
Insulation/studs (NOT much insulation..)
--------
Black tar paper
--------
Interior wall
If I am going to redo the surface layer in certain rooms as I'm putting up drywall and new wallpaper, can I then install some form of windproof material before I put up the drywall? Or will it cause condensation problems?
How else can it be solved?
