    Solar heat gain coefficient is a measure of a windows energy efficiency. Read our guide to learn about factors that affect this metric and how to save money.

  4. The amount of solar radiation that can pass through a window or skylight can be measured in terms of its solar heat-gain coefficient, or SHGC. SHGC ratings are used to help in quantifying the energy efficiency of windows and skylights.

    U-Factor and the Solar Heat Gain Coefficient (SGHC). The U-Factor measures how well the window in-sulates. While the U-Factor can take any value, in general for windows it ranges from 0.20 to 1.20. The lower the U-Factor, the better the window insulates. The SHGC measures how much of the sun’s heat comes through the window. It can range in value

    Solar Heat Gain Coefficient (SHGC) is a measure of the amount of solar heat that enters a building through its windows. This number ranges between 0 and 1 and shows the percentage of solar radiation that passes through a window, both directly transmitted and absorbed and then released as heat inside the building.
