WebJul 12, 2024 · An SRI value is calculated using the roof surface’s Solar Reflectance (SR) and Thermal Emittance (TE). The diagram below describes SR and TE, which are measured … WebRoofing products with high solar reflectance and thermal emittance are referred to as "Cool Roof", which refers to an outer layer or exterior surface of a roof. As the term implies, the temperature of a cool roof is lower on hot sunny days than for a conventional roof, reducing cooling loads and energy required to provide air conditioning.
