D-S Exteriors provides Low-E glass for your windows, if desired. We hear the term, Low-E, but are not always sure what it means. In “Low-E”, the “E” stands for “emissivity”. Low-emissive glass has been treated with an invisible metal or metallic oxide coating, creating a surface that reflects heat, while allowing light to pass through. Windows treated with Low-E coatings are proven to reduce energy consumption, decrease fading of fabrics, and increase overall comfort in your home.
