What Is Low-E Glass in a Replacement Window

Low-E glass – or low-emissivity glass – is a special kind of glass used in the construction of replacement windows. Multiple microscopic layers of silver and other metals with reflective properties are applied to the glass during the manufacturing process. These reflective layers are specially designed to allow in the maximum amount of visible light while reflecting as much of the ultraviolet and infrared light as possible.

There are two common types of low-E coatings, passive and solar control. Passive low-E coatings are applied directly to the glass as it is being produced on the float line using a method called the pyrolytic process. Passive low-E coatings are better for colder climates as they allow some of the sun’s infrared light and heat to pass through the window which can make a home feel warmer. Solar control low-E coatings, on the other hand, are applied after the glass has been manufactured and cut into pieces. Solar control low-E coatings are more ideal for mild to hot climates where air conditioners are used frequently. Generally, low-E glass windows with solar control coatings are thought to be superior to low-E glass windows with passive coatings.
