Modern windows incorporate more technology than ever before to help increase durability, frame profile, and most importantly energy efficiency.
One of the most effective and popular methods of increasing a windows energy efficiency is by applying a low-e film to the windows glass. Low-e film is a invisible exterior film applied to the window glass to help reflect infared (heat) light from entering your home in the summer and leaving your home in the winter.
An added benefit to that reduction in infared light is the added reduction in ultraviolet light, this helps prevent fading of your interior furniture and carpeting.
Low-e film is known for its slightly green hue when compared to raw clear glass.
