Service Cavity OK for Backsplash and Mirrors?
Climate Zone 6A, Ottawa Ontario
My proposed wall is double stud cellulose with a 2×3 service cavity. The service cavity would be filled with a compressed R12 fiberglass batt for around R9-R10. Vapor barrier will have variable permeability, probably Membrain.
With a fiberglass filled service cavity on the inside of my vapor barrier, should I be concerned with moisture buildup behind a kitchen backsplash/cabinets or bathroom mirror? Should I be using green drywall in the kitchen just in case?
