Air gap between cathedral roof insulation and inner wall
Hello, thanks for entertaining my question. I need to obtain r-38 in my cathedral ceiling (really an A-frame), and the rafters are 11 1/4 deep. There will be 2″ of closed cell foam against the inner roof deck. Can I leave a gap between the foam and 6″ of fiberglass and drywall? If so would I use something like simpson strong tie insulation support?
