My house built in 1965 has a vaulted ceiling with no insulation! Construction is 4x12 beams 4 ft center with 2x6 t&g on top of that and then probably a layer of plywood then fiberglass shingles. Love the look of the beam / wood ceiling inside, but may have to sacrifice that for heat unless anyone has a better idea???
If I add insulation between the beams inside, covered with either drywall or other wood, do I have to provide ventilation?
or can it be sealed???
Thanks, Steve
