I’m removing the Sheetrock in a cathedral ceiling and installing shiplap pine, nailed directly to the rafters. There are ridge and soffit vents and fiberglass batt insulation. I’m concerned with drafts at the shiplap joints (the house is in New England) and thinking of installing Tyvek between the insulation and the paneling. Will this cause a moisture issue? I could also caulk the joints as I install the boards but this would be a lot more work. Thoughts?
