WebWhat is the SRI (solar reflective index) of Indiana limestone? SRI measures the ability of a constructed surface to reflect solar heat. Designing with high-SRI materials like Indiana Limestone products is important because it can reduce the “heat island effect” commonly associated with urban areas. Indiana Limestone’s SRI ratings make it ... The Solar Reflectance Index (SRI) is the measure of solar reflectance and thermal emissivity of materials. Solar reflectance or reflectivity is the ability of a material to reflect solar energy from its surface into the atmosphere. Emissivityis a material’s ability to release absorbed energy. SRI is used to indicate how hot … See more Cool roofs stay cool in the sun by minimizing solar absorption and maximizing thermal emittance.
