What is a Low E Window?

If you are considering replacement windows for your home, then it is advisable to get windows with Low E glass. Low E stands for Low Emissivity. Emissivity is the measure of a material’s ability to radiate energy. When the glass of a window has a Low E coating, this mean that the window is better able to reduce the amount of heat radiation that enters the home, making the window more energy efficient.

When ultraviolet and infrared light from the sun passes through the glass pane of a window, the glass absorbs this energy and re-radiates it into the home. Low E glass coatings were developed specifically to minimize the amount of ultraviolet and infrared light that can pass through the glass. Additionally, it reflects heat, so in the winter it will reflect heat back into your home and in the summer it will reflect heat back outside. The coating is extremely thin, so it does not obscure the view through the window.

The replacement windows installed by BELDON® are equipped with Low E glass in addition to numerous other features that make them extremely energy efficient, including warm-edge spacers, multiple panes of glass, and multi-chambered frames. Plus, our proficient installers meticulously measure twice before skillfully installing our windows to ensure a perfect fit that prevents air leakage around the window. And, for added peace of mind, our windows are protected by a lifetime warranty.
