Off-grid cabin: Cathedral ceiling insulation?
First off thanks for your help. We have a 500sqft off grid cabin in the Upper Peninsula of Michigan. Currently the inside is down to studs and we need to install insulation in walls and ceiling. Cathedral style ceiling–not vented. The cabin is heated by a wood stove and will be used once a month for 4 nights MAX. As its 6 hours from home. The exterior is barn metal and tyvek. No insulation. We are on a limited budget as this is basically a hunting camp/summer retreat. After insulation we will install pine T&G.
As of right now I am leaning towards cut & cobble 2 inch rigid foam so that I have some sort of vapor barrier. We can not afford spray foam. What other options do I have? Could I do fiberglass batts in walls? Ceiling? The cabin will have limited use.
