The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions

The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits
