45" Wide SuperPerf AtticFoil® for Over Insulation

SuperPerf™ 45″ wide radiant barrier is a double-sided roll that has been punch-perforated for maximum breathability. If you are laying radiant barrier foil on top of existing insulation, you should use SuperPerf™. This product is an AtticFoil™ exclusive and was designed for over-the-insulation installations inside attic spaces. SuperPerf™ is a punched foil (vs the traditional pin-perforations) which allows more water vapor to pass through the foil’s surface; this foil virtually eliminates the possibility to trap moisture underneath it. Just like all of our products, SuperPerf™ is strong and heavyweight, made with pure aluminum. You cannot cover SuperPerf™ with more insulation or flooring on top, it must be the top-most layer on your attic floor to work as a radiant barrier.
