What is Low-E glass!

  One common question I get while cleaning windows is what is Low-E Glass. We here at Innovative Glass 865.455.9871 will help you understand this.


 Low-emissive (Low-E) glass is window glass that has been treated with an invisible metal or metallic oxide coating, creating a surface that reflects heat, while allowing light to pass through. Windows treated with Low-E coatings are proven to reduce energy consumption, decrease fading of fabrics, such as window treatments, and increase overall comfort in your home.
  The heat that passes through your window glass is measured by the U-factor or ultraviolet light. The lower the U-factor the more energy-efficient your glass is. This type of light is produced by the sun and generates heat in your home. Too much of this heat, especially during summer, can cause your air conditioning bill to go up in an effort to keep your house cool. Low-E glass reduces the amount of ultraviolet light that enters your home, without blocking visible light.
 Conversely, in winter, Low-E glass reduces the amount of heat lost through your windows from the inside of your home, keeping heating costs down. Depending on your home's heating and cooling needs, various types of Low-E glass have been developed to allow for high, medium or low solar gain.

  In warmer climates, Low-E coating should be applied to the outside of window pane to keep the sun’s heat out. While in colder climates, Low-E coating should be applied to the inside window pane of glass to keep heat trapped in. This way, radiant heat is kept on the same side of the glass from which it originated. Keep in mind this coating is applied in between your double pane window and window cleaning will not effect it in anyway!!
