A Closer Look At Radiative Properties
What is Thermal emittance (TE) ?
How important of Solar Reflectance Index (SRI) ?
Codes, standards and programs that specify cool roofing requirements may also reference an additional calculated value,the Solar Reflectance Index (SRI). SRI allows actual measured solar reflectance and thermal emittance values to be combined into a single value by determining how hot a surface would get relative to standard black and standard white surfaces.
