Is Paint Really A True Radiant Barrier?
Let me start off by saying this, if you are considering having a true “Radiant Barrier” installed in your home the paint is not an option. To qualify as a Radiant Barrier a material must have an emittance value of 0.1 or less, our RG 2 Industrial Foil has an emittance value of .03 and as you can see on the chart to the right the best paint only has an emittance value of .23. To help you understand, “Emittance Value” is the amount of heat that the material being used gives off to the air below, you want the emittance value to be as low as possible! Our RG 2 Foil value is .03 meaning that it is reflecting 97% of the incoming radiant heat and only allowing 3% to penetrate through.

How Long Will The Paint Be Effective? Radiant Barrier paint is not a process that only has to be done 1 time, some paints have to be recoated in as l
