What is the recommended method for insulating a cathedral ceiling in a moisture-laden home?
My split level home was built in the 60’s with insulating practices of the the era. No moisture barrier under concrete basement floor. R-3 fiberglass batt, fiberboard sheathing.
After structuring for an open floor plan and removing all the old 2×6 ceiling joist I have to re-insulate as well as re-roof. I mention this because I have the opportunity to add neopor foam board to top of roof sheathing. Really can adapt to any recommendation for ceiling , but will have to live with leaky house for a while.
Appreciate any help, thank you.
