Before installing a couple of mini splits for my barn/shop I was advised that at least some roof insulation would help. I planned to use R-19 faced fiberglass batts between the 2x10 rafters and cover it with a layer of white scrim paper. Then I found this double insulated cover that might be a good substitute for the scrim paper. I plan to eventually sheet the ceiling with drywall or tongue and groove wood paneling but not now. Any comments or suggestions?
