Radiant Barrier Finished Attic

But a radiant barrier is very effective addressing another way to transmit heat.

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. 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. If your house doesn t have continuous ridge and soffit vents so it s trapping excess heat in the attic that s a very cost effective improvement.

Radiant barrier is a home insulation type that is focused on reducing summer heat gain. In combination these are very effective means to keep your attic and home cool. Radiant barriers are made of aluminum and designed to reflect radiant heat from the sun. A radiant barrier works best when it is perpendicular to the radiant energy striking it.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. When installed properly radiant barriers can reflect up to 95 of the radiant heat off the attic. The best way i have seen to describe this effect is it s like putting your home or office under a shade tree. You still need ventilation addresses convection and insulation addresses conduction.
