What are the Shading Coefficient and the Solar Heat Gain Coefficient?
A2 – These terms are mathematically related and both describe the solar energy blocked from passing through a glass material. The shading coefficient is the ratio of solar energy that passes through a piece of glass relative to piece of 1/8″ clear glass ( which has a shading coefficient of 1.0. Solar heat gain coefficient represents the solar gain through the glass relative to the incident solar radiation; it is equal to 86% of the shading coefficient. In either case, a lower number indicates improved solar control over the 1/8″ clear glass baseline.
