      Polyurethane is better insulator, doesn’t absorb moisture and doesn’t require a vapor barrier but is also much more expensive. It’s what I insulated my shed with so that I can let it get cold if need be and will not have moisture problems later.

        I always underestimate oil biproducts in the market, but maybe that is the play.
