Witryna3 cze 2024 · SHGC refers to the window’s Solar Heat Gain Coefficient. And, because of where we live, this is a very important factor to consider in your new or replacement windows. The SHGC rating refers to the window’s ability to block the sun’s radiant heat. This too is expressed in a decimal with a lower number being better. WitrynaThe SHGC is found by multiplying the shading coefficient by 0.87. The shading coefficient is the old metric that window companies used to determine the thermal performance of a glass unit. The lower the number, the better solar heat gain coefficient your window has. Why is SHGC Important?
