Benefits of low-e glass:

Installing energy efficient windows with low-emission (low-e) glass helps our customers to reduce the amount of ultraviolet (UV) light and radiation entering their home. By keeping the warm air out in the summer and the cool air out in winter, properly installed low-e glass can reduce your overall energy bills by up to a third.

Low-e glass contains a coating of microscopically thin, virtually invisible metallic oxide layers applied on the window surface. A protective, transparent coating ensures long lasting durability and aides in the suppression of unwanted noise from the street or jets flying overhead.

Not only does low-emission (low-e) glass help to keep the warm air out in the summer and cold air out in the winter, it provides protection for your artwork, furniture and drapes to prevent against sun damage and premature fading.
