WebInfrared Emittance (also referred to as Thermal Emittance) is rated between 0 and 1 and rates the ability of a product to cool itself by releasing thermal radiation back into the atmosphere. Painted finishes often maintain a lower emittance value than bare metal products. Solar Reflective Index (SRI) WebDuring the daylight hours, a roof is constantly subjected to solar energy striking its surface. The term “Solar Reflectance” is a measure of the amount of that solar energy that is immediately reflected from the surface. It is not reflected heat but reflected electromagnetic energy from the sun.
