Radiant Barrier Spray
Spray-On Radiant Heat Barrier is essentially a “liquid foil”. We all know that foil is a heat barrier. There are many brands of paint that 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 is the best product to install. However, foil is indisputable for out performing radiant barrier spray paint. Read this report from RIMA for complete comparisons of radiant barrier paint. Our radiant barrier spray is a high-tech coating that was originally developed by the U.S. military to make their vehicles invisible to heat-seeking missiles. Its remarkable heat-shielding properties make it an ideal radiant barrier for your home or business.
A single, thin coat of our spray applied to the underside of your roof deck will block up to 80% of the sun’s radiant heat from entering your home through the attic.
And in winter, the same barrier will reflect back up to 80% of the heat that tries to escape from your home through the attic. Yet unlike foil substrates, our radiant barrier spray can be applied in a matter of hours instead of days. It goes on evenly, with no gaps or holes. And because it is sprayed on, it can easily be applied to existing roofs.
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 qualities that make it work: Reflectivity and Emissivity. Reflectivity is the ability to “reflect” radiant heat while Emissivity is the abiltiy NOT to “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.
