The R-value describes the effectiveness of insulating materials. Because COOLWALL® does not work by an insulation process, it doesn’t have an R-value. Instead, it works by reflecting the sun’s infrared energy, so the wall doesn’t get as hot in the first place. This reduces the amount of heat that insulation materials, like fiberglass, have to keep out. By reflecting solar heat, COOLWALL® is both reducing surface temperatures and your energy bill!
