RadiantGUARD® is Superior to "Radiant Barrier Paint"
There are several suppliers of products misnamed "radiant
barrier paint" that are designed to be sprayed on the underside of the roof
decking in the attic. These "spray" products are paint
solutions with added metallic flakes designed to reflect
These paint solutions are NOT
true radiant barriers per the definition provided by the US Department of Energy
DOE Radiant Barrier Definition : a product must have a
low emittance of 10% or less and high reflectance of 90% or more to be
classified as a "radiant barrier"
Ultima radiant barrier foil insulation products have
an emittance of 5% and a reflectance of 95%;
far exceeding the DOE's radiant barrier minimum classification requirements.
For more information, visit the
Department Of Energy website.
These spray paints do not come close to Department of Energy's
definition for a radiant barrier.
In 2006, David W. Yarbrough, Phd, PE conducted testing of
the reflectivity properties
of leading reflective paints.
He found that the emittance (heat that passes through the paint) of these
paints varies widely. In fact, ONLY FOUR of the products tested
actually passed the DOE's required definition for such a paint product
intended to reduce heat trasfer.
barrier emits only
3% making them FAR SUPERIOR
to radiant barrier paints.
Details of the findings can be found in
Dr. Yarbrough's study.
While installation costs of radiant barriers and
reflective paint products equate to about the same, RadiantGUARD® radiant
barriers provide a quicker ROI (return-on-investment) because they block
much more heat than the paints.
Additionally, reflective paints require more installation
paint sprayer, protective clothing, and face masks making it a more difficult
task for the average do-it-yourself
(DIY) individual. However, our RadiantGUARD® products are
extremely easy to install requiring less installation tools and effort which
results in a quicker ROI.
