Many newer homes in Florida come equipped with Low Emissivity (or “Low-E”) windows. As you can guess from the name, these types of windows are specially designed to reduce the amount of energy emitted through them. Low-E windows typically have one or more layers of a coating that is designed to block things like infrared or ultraviolet light, while maintaining the same amount of luminance allowed to travel through the window.
If you suspect that your windows are not doing their part to efficiently maintain energy use in your home, or you’re in the market for new windows, be sure to consult a professional before deciding on the best Low-E windows for you. There are a few different types of coatings available, and a lot of big scientific words are used to describe how they work. Phrases like solar heat gain coefficient, visible light transmittance, and magnetron sputtering vapor deposition may not mean much to your common consumer, but a professional can help you decode them successfully.
