![]() How Does a Radiant Barrier Roof Work?Īttics are hot under normal conditions due to the sun’s heat bearing down on the roof shingles. Placing a radiant barrier on the underside of your roof limits heat gain in the attic, which in turn reduces heat in your home’s living space. Lying beneath the sun-exposed roof, an attic accounts for a large amount of square footage inside a home. A hot air balloon uses convection to rise in the air.Ī significant source of heat transfer into a home occurs in a home’s attic. Convection is the movement of heated fluid, such as air, over a short period of time. This is what happens when a chocolate bar melts in your hand, for example. The transfer of heat through physical contact is conduction. However, unlike thermal insulation materials, barriers do not reduce the other two types of heat transfer – heat conduction and heat convection. Commonly installed in attics, the heat is reflected rather than absorbed by the barrier. The roof radiant barrier reflects this heat and reduces temperatures indoors and cooling costs. This is seen when the heat from the sun intrudes into your home. As a result, heat is transported from the hot item to the cooler item. Radiant heat is a type of heat transfer, which is the transfer of heat or thermal energy between physical items. What Is a Radiant Barrier?Ī radiant barrier roof is a reflecting surface that blocks radiant heat and acts as a barrier between your conditioned air space and the sun. In this post, our Bossier City roofers at Quality Exteriors explore radiant barrier roofs, their pros and cons, and why they are an excellent option for keeping you from sweating over a high electric bill. ![]() ![]() And they’re simply another useful tool for keeping some of that Southern heat out of your house.
