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...

The Solar Heat Gain Coefficient (SHGC) is the percent of solar energy incident on the glass that is transferred indoors both directly and indirectly through the glass. The direct gain portion is the solar energy transmittance, while the ind...

The Solar Heat Gain Coefficient measures the amount of solar heat that gets through a window. The lower the SHGC, the better a window is at reducing heat gain, and in the end, the cooling costs that go along with it.

is a measure of the window’s ability to reflect the rays of the sun off the window. Anything lower than .40 SHGC would be considered a good window. For SHGC, lower scores demonstrate a window more able to reflect the sun’s rays.
