I've got between 1 1/2 "-2 " on the walls, and 2"-2 1/2" on the roof. I quit paying attention to the "R value," considering that the sealing affect is tough to measure.
I've been in buildings with 8" walls, filled with fiberglass batts, and plastic sheeting, but still have drafts on breezy days
I'll have a better idea of how well it works a year from now. I don't have the concrete, or doors in yet.
