If you’re in the market for replacement windows , you’ve probably heard the term “low-E glass” — but you may not know exactly what it means. In today’s post, the experts at Renewal by Andersen® of Central PA explain what low-E glass is and how it boosts the energy efficiency and overall performance of windows.
The “E” in Low-E stands for “emissivity.” A low-emissivity window is built with glass covered by a very thin, metallic oxide coating. The coating is scratch-resistant, preventing micro-abrasions from dust particles and the like. Low-E is commonly associated with energy efficiency.
Low-E windows reflect heat quite effectively. Renewal by Andersen customers enjoy this benefit, particularly during the summer months. While other homes may see marked increases in their cooling requirements when it’s hot outside, homeowners with Low-E glass windows may actually see a reduction.
Low-E glass is also easier than regular glass to clean, making the window lower maintenance, which is a plus for any homeowner. While Low-E glass keeps heat out, it still allows visible sunlight to enter your home. This means you get the best of both worlds: abundant daylighting in your home but without the unwanted heat gain that would accompany it if you had lower-quality windows.
