What is Low-E Glass?

If you are actively shopping for windows, you have probably seen the phrase “low-e glass” pop up several times. So what exactly is low-e glass? Low-e glass, officially called low emissivity glass, is a type of glass that is treated to decrease the amount of heat that is transmitted through your window into your home.

Low-E glass allows visible light to enter your home, but blocks ultraviolet light—the light responsible for generating heat. The glass works by reflecting heat back to its source, keeping your home’s temperature at a more comfortable level while protecting your home’s interior.

Benefits of Low-E Glass

There are several benefits to installing windows in your home with low-e glass. The most notable advantages of low-e glass are:

  • Save money on your heating and cooling bills

    – low-e coatings provide excellent energy efficiency.

  • Year-round comfort

    – low-e glass keeps your home cooler in the summer and warmer in the winter. Low-e glass solutions produce a very low U-factor and heat gain coefficient.

  • Easier cleaning

    – low-e glass can help reduce the amount of dirt and grime that accumulate on your windows, keeping them cleaner for longer.

  • UV protection

    – our low-e glass can block 95 percent – 99.9 percent of the sun’s UV-A and UV-B radiation. UV-A and UV-B radiation can cause your furnishings and flooring to fade, so blocking these harmful types of solar radiation can save you money and extend the life of your furnishings.
