Insulating walls without an exterior vapor barrierr
I have a 1930s seasonal camp in Limington, Maine. Open studs on interior walls. Cedar clapboard exterior siding over T&G pine sheathing. No paper (or other vapor barrier) between exterior siding and sheathing. Siding and sheathing in good condition. Want to insulate exterior walls to extend seasonal use of camp - but concerned about lack of vapor barrier. Is it safe to install paper-faced fiberglas insulation on the exterior walls to be later covered with pine paneling? Thanks for any advice you can provide.
