CoolStar roofing products are more energy-efficient than standard roofing products and exceed ENERGY STAR® and California Title 24 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 roofing products surpass both of these important, industry-recognized standards.
