U-Value is the measure of a window’s ability to reduce heat loss during indirect radiation exposure; such as during the winter months.

Solar Heat Gain Coefficient (SHGH) is a measure of a window’s ability to reduce heat gain direct radiation exposure; such as during the summer months in warmer climates. A lower SHGC translates into less direct heat being pulled into the home resulting in lower cooling cost.
