Radiant Barrier Finished Attic

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

Also the greater the temperature difference between the sides of the radiant barrier material the greater the benefits a radiant barrier can offer. A radiant barrier works best when it is perpendicular to the radiant energy striking it. Radiant barriers are made of aluminum and designed to reflect radiant heat from the sun. Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes.

In combination these are very effective means to keep your attic and home cool. But radiant barrier maybe but it s kind of hard to tell because there s a lot of claims of energy efficiency but it s very difficult to prove it out. When installed properly radiant barriers can reflect up to 95 of the radiant heat off the attic. You still need ventilation addresses convection and insulation addresses conduction.

The best way i have seen to describe this effect is it s like putting your home or office under a shade tree. Unlike traditional thick layers of insulation radiant barrier is a thin reflective material. A radiant barrier can lower heat transfer from attics to the building below keep the attic space cooler and lower cooling costs by up to 17 in warmer climates. Radiant barrier is a home insulation type that is focused on reducing summer heat gain.
