**U-factor measures how well a product prevents heat from escaping. The rate of heat lost is indicated in terms of U-factor (U-value) of window assembly. U-factor ratings generally fall between 0.20 and 1.20. The lower the U-value, the greater a window’s resistance to heat and the better its insulating value.
