Compare the cool roof benefits of a roof restoration with Energy Star Heat Reflective Paint to a roof restoration without the use of a solar paint.

Temperature Differences to ASTM E-1980-01 Standard vs Energy Star

Compare The Difference

The temperature values stated on the chart below is the substrate temperature reduction that can be achieved by using Energy Star products on a building envelope as compared to conventional materials.

The data is based on information obtained from tests conducted to ASTM E 1980-01 where the calculation is based on a mathematical formula that includes values for thermal emittance, total solar reflectance, solar absorbance, three convective coefficients, solar flux, the Stefan Boltzman constant, and various other coefficients.
