Abstract
Each product in the Rated Products Directory has a CRRC product rating that indicates the radiative performance—solar reflectance, thermal emittance and solar reflective index—of a roofing product. Solar reflectance is the fraction of solar radiation reflected away from a roof, and thermal emittance is the efficiency by which a roof reradiates absorbed heat.
