Radiant Barrier Insulation

Worried about your rising energy costs?

Do you avoid going into your attic in the summer out of fear that you might die of heatstroke?


Roofing Radiant BarrierAt Athens Roofing, we offer a variety of products that, when used alone or in combination, can dramatically reduce your summer cooling costs.


Athens Roofing is excited to offer the installation of Radiant Barrier insulation as a part of your roofing project. This type of insulation can be applied to either a metal roof or a shingle roof and can offer dramatic energy savings. A radiant barrier is a foil-like metallic sheet that reflects most radiant heat from entering your home through your attic. At Athens Roofing we’ve worked hard to understand the benefits of energy efficient roofing practices so that we can pass along that knowledge to our customers. Below, we’ve tried our best to explain, in plain English, the benefits of radiant barriers. For more information, please see some of the links below or call us today for a free roof inspection and a proposal to install roofing and insulation to your home.


Sooo.... What exactly is radiant heat and how does it relate to my attic?


Radiation is the way heat is transferred from the sun to Earth. Infrared, or radiant heat, is invisible. Radiant heat is the transfer of heat from one object to another object without direct contact. Energy is transferred in a waveform, similar to how sound travels. This energy is then converted to heat when it comes in contact with another surface.


When the sun heats a roof, it's primarily the sun's radiant energy that makes the roof hot. Much of this heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.


When you add a radiant barrier to your roof assembly, it becomes your first line of defense against heat being transferred into your attic and then into your cooled spaces of your home. Virtually ALL of the heat entering from a roof into an attic is radiant heat. Over 90% of heat from a roof is transferred by radiant heat into the attic. The fiberglass insulation in your attic is merely preventing the heat which has entered your attic in the form of radiant heat from being transferred into the conditioned (cooled or heated) part of your home. A radiant barrier makes your regular, existing attic insulation more effective. It is an entirely different type of insulation that keeps the existing insulation cooler.


Simply put: radiant barriers reduce the amount of heat entering the home/building. Lessen the amount of heat gain helps to reduce the energy needed to remove the heat (air conditioning) and makes the living space more comfortable.


How Much Will I Save?

As we mentioned above, it depends on a few factors. In general, you can expect a 5 to 25% savings. You can use this simple calculator to get an idea about how much your new radiant barrier will save you. Keep in mind that actual savings may vary and that your existing insulation, the presence of air ducts in your attic and the layout of your home will affect the amount you save.



Installing radiant barrier under your new roof is almost like putting a giant tree over your home. Bang for the buck, you can not beat it. Your home will have immediate energy savings, and be more comfortable year round. If you have chosen to spend the extra money on a high-quality roof from Athens Roofing, why not spend just a little more to make the roof pay for itself through energy savings from a radiant barrier?
