I read your article on insulation an older home that does not have sheathing behind the ceder lap siding. The house is in southern Missouri so I was planning on 0.75 inch foiled rigid foam board (foil facing the exterior siding with a 0.75 inch air space. My question is should the fiberglass batting have kraft paper or just the fiberglass batting. I was planning on 0.5 inch sheet rock for the interior walls.
Thank you for your time.
