Why Low-E Windows
Low E glass, the E stands for emissivity, is a great favorite among home owners. Low E, low emissivity coating, is a unique microscopic glaze that helps minimize the amount of ultraviolet, infrared and visible light from penetrating the glass keeping you cooler in the summer and warmer in the winter. These windows can be installed in all areas of the US.
Windows without Low-E have a much poorer ability to keep heat in, thus allowing warm air to escape the building in the winter, and increase the demand on your heating and cooling systems.
Window manufacturers have, over the years, developed many new insulating and glazing techniques to improve the performance of windows, save on your heating and cooling bills, save on any carpet and furniture fade, and add overall comfort to your home.
Pros of Low-E Windows
The Low-E coating reflects heat back to its source so it helps your home stay cooler in the summer and warmer in the winter.
The coating won’t scratch off because it is applied to the inside of the glass.
It help protects against UV fading of any nearby furniture.
It requires no special cleaning.
Cons of Low-E Windows
Low-e coatings typically add about 10 to 15 percent to the cost, but they reduce energy loss by as much as 30 to 50 percent. So this really shouldn’t be a negative issue.
Low-E is sprayed on with coats. Some windows manufacturers, in order to obtain a higher U-Value, add many coats, thus giving the window a bronzed look, especially from the exterior.
