How a Radiant Heat Barrier Works
When the sun heats a roof, it's the sun's radiant heat energy that makes the roof hot. Much of the heat is transferred to the attic by conduction. It travels, through the roofing materials and winds up in the the attic where it increase the temperature in an unprotected attic by as much as 50 degrees. A reflective heat shield reduces this heat transfer and makes your attic much, much cooler.
Studies show that radiant heat barriers can reduce cooling costs by as much as 20%. Adding one to your home will cause your H.V.A.C. system to work less & may even allow you to have a smaller AC unit.
Why Add a Radiant Heat Barrier to Your Home?
We all know that it’s easier to keep your home cool at night but have you ever asked yourself why? Radiant heat is the answer. The sun produces a lot of infrared heat. Obviously, when the sun goes down, the radiant heat is drastically reduced. Even though the outside air temperature only changes a few degrees, your H.V.A.C. system doesn't have to work near as hard at night because the radiant heat has been eliminated.
Attic reflective barriers work the exact same way. Installing a radiant barrier is like having a huge shade tree covering your entire home. It deflects the infrared heat back outside, where it belongs. In fact, foil radiant heat barriers will deflect up to 97% of all radiant heat that comes in through the attic. As a result you could reduce your heating and cooling costs by as much as 20%, just by adding a radiant barrier to home.
Getting the Most Out of Radiant Heat Barriers
How well radiant barrier insulation works depends on several factors. Generally the more roof surface you have, the greater the impact you will see. Ranch style homes often see the largest impact but almost any home can benefit from a radiant heat shield, one way or another. Remember, reflective foil insulation is like shade, so the more coverage you have, the better your results.
Installing a radiant heat barrier will reduce your home's heating and cooling costs & make your home more energy efficient. When you combine the infrared heat protection of a radiant barrier with adequate amounts of blown-in insulation and one of our air sealing packages you will maximize your energy savings and slash your energy bills.
