We're remodeling my sons kitchen. Older home, plaster lath, and no insulation. Complete demo, down to bare studs, now re-wired and ready to go back with sheetrock. We have a small area that is vaulted.( What was originally a porch area.) It's about a 3 foot wide vault area the length of the kitchen. Trouble is, ceiling stud cavity in this area through here is only 3 1/2". Is it OK to let fiberglass insulation touch the bottom of the roof sheathing? I don"t want any overheating of shingles, and/or condensation issues below. I know on new home vaults, it shows air flow travel above fiberglass. That is not possible in our situation. Should we leave this area un-insulated, or is this ok to insulate?
