SmartFOAM is a 3mm closed-cell foam core faced with reflective foil, sold as a 16 in x 10 ft roll. It blocks radiant heat rather than slowing conductive heat, and the maker claims 97% reflectivity with an R-value up to 15.62 for one layer and 21.10 for two in a building envelope. That puts it in the same class as other foil-faced foam rolls, but far below the R-value of batt or blown insulation per inch. It suits small jobs where fiberglass is awkward: garage doors, attic rafters, duct wraps, sheds and radiant floor underlayment.
