Solar reflective index roofing
WebAug 1, 2014 · Solar reflectance (SR) is the ratio between the solar energy globally reflected by a surface and the total incident solar energy. Traditionally, roofing materials’ SR can be between 0.05 and 0.5 (e.g., 0.05 for black membrane roofs, 0.08–0.5 for … WebEfficient Design. Cool Roofs. A cool roof is designed to reflect more sunlight than a conventional roof, absorbing less solar energy. This lowers the temperature of the building just as wearing light-colored clothing keeps you cool on a sunny day. Conventional roofs can reach temperatures of 150°F or more on a sunny summer afternoon, sun.
