ENERGY PERFORMANCE RATINGS – U-FACTOR, SOLAR HEAT GAING COEFFICIENT,VISIBLE TRANSMITANCE
U-factor measures how well a product prevents heat from escaping a home or building. U-factor ratings generally fall between 0.2 and 1.20. The lower the U-factor the better a product is at keeping heat in. U-factor is particular important during the winter heating season. Solar Heat Gain Coefficient (SHGC) measures how well a product blocks […]
