What Is Low-E Glass and Why Should My New Windows Have It?

Last updated 4 years ago

The modern home is often filled with amazing new technologies that bring extra comfort and security to families. Improved air conditioning and electrical and structural systems have made the most obvious progress in the past 50 years. However, did you know that windows also feature some of the latest innovations?

Low-E glass is a window that is covered with a virtually invisible layer of metallic oxide. This coat can actually reflect the sun’s heat away from the window while allowing natural light to shine through. There are two types of low-E coatings that vary in intensity and performance. A hard coat, which may have a bluish tint, involves a process of pouring a layer of molten tin on a sheet of glass. A soft coat involves the application of tin to the glass in a vacuum chamber that is electrically charged. The main difference between the two types is that a hard coat is more durable, while a soft coat offers a higher emissivity.

• The Application
Houses that are built in hot climates should have low-E coatings applied to the outside panes of glass. This will allow the window to radiate heat away from the house, thereby keeping the space cool. If you live in cold climates and are interested in windows that are tailored to keep heat inside the house, the low-E coating should be applied to the inside pane of glass.

• The Benefits
Apart from the obvious benefits of keeping your home cool or warm, low-E glass makes it easy to save energy. When your air conditioner or heater is not expending extra energy to maintain a certain temperature in your home, you can rest assured that your utilities bill will also show savings.
