WebFactors to Consider When purchasing ENERGY STAR qualified windows, look for the 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. WebSolar Heat Gain Coefficient (SHGC) measures the fraction of solar energy transmitted and tells you how well the product blocks heat caused by sunlight. SHGC is measured on a scale of 0 to 1; values typically range from 0.25 to 0.80. The lower the SHGC, the less solar heat the window transmits.
