Lurker here; now exposed. My husband and I bought a shell of a cabin and 7 acres in NH. We have a 3 to 5 year plan to move permenantly there and do a real "simplistic lifestyle". We will be installing a wood burning stove to heat the whole thing (open flooring - 20 by 32 ft one floor). But we will freeze our buns off if we don't insulate well. The outside is simple 10" barnboard with approx. half to one inch seperations. Over these we place 2" battens. The studs are 2x6 so we will do the regular fiberglass stuff but because the barnboard are the only seperation between the fiberglass and outside, do you place anything else inbetween. Is 6" fiberglass the best? Help. I only have so many layers of clothes!
