CoolStar-coated roofing products are more energy-efficient than standard roofing products and exceed ENERGY STAR standards.
To meet ENERGY STAR standards, a low slope roofing surface must have a solar reflectivity of .65 (meaning it reflects 65% of the radiation away from the surface and absorbs 35%).
In general, an ENERGY STAR-labeled product can help reduce energy costs by as much as 30%.
The state of California has an even tougher requirement for a "cool" or energy-saving roof called Title24. To comply, a low slope roofing surface must have an initial solar reflectivity of .70 and thermal emittance of .75. CoolStar-coated roofing products surpass both of these important, industry-recognized standards.
All CoolStar cap sheets have initial ratings for solar reflectance and thermal emittance from the Cool Roof Rating Council (CRRC).
