Heating and cooling costs have become a major factor in sunroom choice. There’s much to learn about U-Factor and Solar Heat Gain Coefficient performance by reading the National Fenestration Rating Council (NFRC) label on a window or door. The NFRC is an educational organization that provides the public with the information it needs to make more informed independent choices about the energy performance of windows and doors. NFRC ratings are used to determine qualification for ENERGY STAR.
U-factor gauges the efficacy of a product to preventing heat loss. Heat loss rate is designated in terms of the U-factor (U-value) of a window assembly. U-Factor ratings usually fall between 0.20 and 1.20. The insulating value is indicated by the R-value which is the inverse of the U-value. The lower the U-value, the greater a window's resistance to heat flow and the better its insulating value.
Solar Heat Gain Coefficient (SHGC) gauges efficacy of a product to block heat generated by sunlight. The SHGC is the fraction of incident solar radiation admitted through a window, both directly and through absorption. SHGC is expressed as a number between 0 and 1. The lower a window's SHGC, the less solar heat diffusion.
