What is Low-emittance (Low-e) Coating

When shopping for windows or doors, you may have heard the term “low-emittance” or “low-e” coating. But what exactly is low-e coating, and how does it impact the energy efficiency of your home?

Low-emittance (low-e) coating is a thin, virtually invisible layer of metal or metallic oxide that is applied to the surface of window or door glass. The coating is designed to reflect heat, which helps to keep your home cooler in the summer and warmer in the winter. By reducing the amount of heat that enters or escapes your home through your windows and doors, you can improve the energy efficiency of your home and lower your energy bills.

There are two main types of low-e coatings: hard coat and soft coat. Hard coat low-e coating is applied to the glass during the manufacturing process, while soft coat low-e coating is applied to the glass in a vacuum-sealed chamber after the glass has been manufactured.

Hard coat low-e coatings are generally more durable and can be used in single-pane windows, while soft coat low-e coatings are more delicate and are typically used in double-pane or triple-pane windows.

Low-e coatings can also be customized to suit different climates and orientations. For example, windows or doors that face north may require a different type of low-e coating than those that face south, to optimize the amount of heat that is reflected.

In addition to improving the energy efficiency of your home, low-e coatings can also help protect your furniture, flooring, and other belongings from fading or discoloration due to exposure to sunlight.
