SHGC calculates how well a product blocks heat caused by sunlight. In other words, the SHGC of a window measures the rate of heat gain, which determines how well a window blocks heat from the sun. SHGC is similar to the SC(Shading Coefficient), but also accounts for absorbed, convected, and inwardly radiated solar energy.
