In other words, older windows or non-energy efficient windows can increase your energy bills substantially.

Some things to know about energy-efficiency ratings

What Do Low-E Coatings Do?: Low-E coatings are formulated to transmit energy from the “visible” portion of the solar spectrum into buildings while minimizing the amount of “ultraviolet” and “infrared” light or heat energy that passes through. When heat or light is absorbed by the glass, it is either shifted away by air movement or reradiated by the glass surface.

U-Factor: Measures how good a window or door is at keeping heat in. Lower numbers mean better heat retention.

Solar Heat Gain Coefficient: Measures a window or door’s ability to keep heat out. Lower numbers mean better heat resistance.

Reduce solar heat gain coefficient up to 50%

Low-E lowers both U-Factor and Solar Heat Gain Coefficient numbers. In fact, Low-E can reduce the Solar Heat Gain Coefficient by up to 50% over clear glass.*
*Source: The reduction percentage varies based up the type of Low-E selected.
