What Is a Spray-On Radiant Barrier?
Spray-On Radiant Heat Barrier is essentially a "liquid foil". We all know that foil is a heat barrier. Thre are many brands of paint and have different performance characteristics. The best are water-based low-e paint called HeatBloc-75 made by STS Coatings or Radiance e.25. made by BASF. It CAN be a good product if installed correctly. However, foil is indisputable for out performing radiant barrier spray paint. Read this report from RIMA for complete comparisons of rdiant barrier paint.

How does a Radiant Barrier work?
Whether you chose to have the Radiant Barrier Paint sprayed or you choose to do-it-yourself or hire a professional to install Radiant Barrier Foil insulation, your home will be more comfortable and energy efficient. Radiant barrier paint has up to an "e" value of 0.25. This means it reflects or "blocks" 75% of the Radiant Heat transfer from the roof into the attic and then the home. The Radiant Barrier Foil has and "e" value of about .03 meaning it will reflect or block nearly 97% OF THE HEAT GAIN!! This is similar to having a Giant Shade Tree instantly land in your yard! By reducing the radiant heat gain, the attic temperature is cooler by as much as 20-30 degrees. More important than the attic temperature is the reduction in radiant heat transfer into the attic and home. The best way to demonstrate this is to ask - Would you feel "cooler" sitting in the SHADE on a 100 degree day or sitting in the SUN on an 80 degree day? Most would agree they would rather be in the shade even though the air is hotter. The bottom line...A radiant barrier will act like shade for you home. This means less heat gain into your living space and a cooler, more energy efficient and comfortable home with lower electric bills.

A radiant barrier will help stop the heat at the source. Think about this. Where does most of the heat come from on a hot summer day? The sun of course. The heat from the sun drives right through your roof, your attic and into your home. A radiant barrier acts like a mirror or the reflective sunscreen you put up in your car. A radiant barrier saves you money on your summer electric bill and can usually pay for itself in between 2-5 years.

How is Radiant Barrier Applied?
Radiant Barrier Spray Paints are sprayed on the underside of the roof deck and Radiant Barrier Foil Insulation is either stapled across the rafters or layed out over the existing blown-in insulation.

Why is it Applied to the UNDERSIDE of the roof?
At first it does not make sense, but think about this. If you hold a mirror up to the sun and reflect the light on your arm you would SEE the light, but you would FEEL the heat. The sun emits both visible light and invisible infrared energy. It is the infrared energy that is being reflected that you feel, NOT the light. Radiant barrier has two qualites that make it work: Reflectivity and Emissivity. Reflectivity is the ability to "reflect" radiant heat while Emissivity is the abiltiy NOT ro "Release" heat in the form or radiant energy. Want more info? Polar-Ply (a radiant barrier roof deck material designed for new construction has a good website) So, even thought radiant barrier is installed underneath the roof it will still reflect the radiant heat flow.

What about A "Radiant Barrier Rebate"?
Some companies use a "Rebate" as a sales gimmick. If they raise their price and then give a "rebate" do you really get a "deal"?
