How can I seal gaps in a tongue and groove ceiling?My log house is 15 years old. The ceiling is 1×6 tongue and groove boards nailed to 2×8 rafters. Insulation is normal pink batting between the rafters with kraft paper facing the ceiling boards. There is no vapor barrier between the ceiling and the insulation. There is some separation in the boards where they join. I am concerned about heat loss through the gaps.
