Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes. By reducing the amount of radiant heat reaching the insulation in your attic the insulation remains cooler and is able to keep your home more comfortable.

A radiant barrier works best when it is perpendicular to the radiant energy striking it. Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat. Type of radiant barrier application size of your house whether your home is a ranch style or a two story house amount of insulation in the attic effectiveness of attic ventilation color of the roof thermostat settings tightness of the building envelope actual weather conditions efficiency of the heating and.
