Adding additional insulation to existing 2×6 framing
We built our house about 30 years ago when 2×6 framing with plastic vapor barrier inside, 6 inches insulation, 1/2 wafer board, Tyvek house wrap, Cedar lap siding.
We would now like to replace the windows and siding and add additional insulation to the exterior. I have read articles on how much rigid foam we should apply if there was no plastic vapor barrier installed. Also read about rockwool as maybe an option to allow the wall to breath.
Looking for suggestions….thanks!
