WebAug 18, 2024 · The Shading Coefficient (SC) is a measure of the heat gain through glass from solar radiation. Specifically, the Shading Coefficient is the ratio between the solar heat gain for a particular type of glass and that of double-strength clear glass. A lower Shading Coefficient indicates lower solar heat gain. Relationship between SC and SHGC Weban excellent shading coefficient and good visible transmittance. A glazing is generally considered selective if it has relatively high visible transmittance and a relatively low shading coefficient. The ratio of the visible transmittance to the shading coefficient can be used as a metric for selectivity, with ratios greater than 1.0 indicating that
