Exterior walls in an upstairs living space over a garage. Vinyl siding exterior, 1/2" green foam board, 7/16" OSB, are the layers from exterior inward. What would be the proper insulation for the 2x4 walls? Can't afford spray foam. Would like to use Roxul, but our big box stores claim it is unavailable here (north Alabama). Interior wall surfaces will be 1/2" drywall. Should standard insulation be faced or unfaced? Thanks for your replies.
