If you’ve been researching modern windows, you’ve likely come across the term Low-E glass—but what does it mean?
Low-E stands for low emissivity, a property that helps glass reflect rather than absorb infrared and ultraviolet light. Low-E coatings are thin, virtually invisible metallic layers applied to one or more surfaces of the glass. They allow visible light through but reflect heat.
Here’s why it matters:
* Better Insulation: Low-E glass keeps your indoor temperature stable by reflecting interior heat during winter and blocking external heat in summer.
* UV Protection: It helps protect furniture, floors, and artwork from fading caused by UV rays.
* Improved Comfort: Rooms stay more temperate, reducing hot or cold zones near windows.
There are different types of Low-E coatings—passive for cold climates and solar control for hot climates. A professional window replacement near me Chicago contractor can recommend the best option for your home based on your region and energy goals.
