I want to add 2 inches of blue board to the addition I'm building. Will it cause moisture to build on the inside wall?
I live in central Maine on the coast. Some have warned the dew point will fall on the inside of the 2x6 wall and not dry out. Others have said it will dry out in the summertime if i use a breathable paint on the drywall so it can dry out that way.
My slab on the 1st floor is heated and insulated w/ blue board 2" on the sides and 4" on bottom. Please advise.
