What Are Low-E Windows?

Low-E stands for “low emissivity.” These windows feature a thin, nearly invisible metallic coating on the glass surface that reflects infrared light while allowing natural daylight to pass through. In hot climates like Austin, low E windows reduce heat gain inside the home, meaning your air conditioner doesn’t have to work as hard.

Benefits include:



  • Lower utility bills – By blocking heat, low E coatings reduce energy waste.

  • Better comfort – Keep rooms cooler in summer and warmer in winter.

  • UV protection – Low E glass helps prevent fading on furniture, flooring, and artwork.

  • Improved efficiency – Recognized as some of the best windows for energy efficiency available.

When paired with double pane windows or triple pane windows, low E coatings significantly enhance the performance of your home’s glass.

Insulated Window Frames: The Hidden Advantage

While glass coatings are critical, the frame also plays a big role in efficiency. Insulated windows use advanced frame materials and thermal breaks to reduce heat transfer around the edges of the glass. This means the entire unit works together as a thermal window for homes, not just the glass itself.

Advantages of insulated frames include:

  • Reduced drafts – No more hot spots or cold edges near the window.

  • Higher energy ratings – Many are Energy Star rated windows.

  • Noise reduction – Insulated designs block outside noise.

  • Longevity – Stronger materials resist warping and wear.

For homeowners looking for custom energy efficient windows that combine advanced coatings and insulated frames, Eco-Windows Austin offers a full selection tailored to Austin’s climate.
