Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes. Heat moves around your home by conduction convection and radiation. Your attic can get as hot as 150 degrees in the summer. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

Seal spaces around plumbing recessed lights and vents. Fortunately there are a number of steps you can take to reduce attic heat and lower your power bills at the same time. Some studies show that radiant barriers can reduce cooling costs 5 to 10 when used in a.
