Are you looking to lower your energy bills and be more energy efficient? If so, energy efficient windows may be a good option for you. But how do energy efficient windows work?

Energy efficient windows are designed to keep heat in during the winter and out during the summer. They do this by having a special coating on the glass that reflects heat. This coating is usually made of a material called Low-E glass.

Low-E glass is a type of glass that has a very low amount of thermal conductivity. This means that it doesn’t transfer heat very well. So, when the sun hits a window with Low-E glass, the heat is reflected back outside. This helps to keep your home cooler in the summer.

In the winter, energy efficient windows work to keep heat in your home. They do this by allowing the sun’s rays to pass through the glass and into your home. This helps to warm your home and lower your heating bills.

Energy efficient windows are a great way to save money on your energy bills and be more energy efficient. If you’re looking to replace your windows, be sure to look for windows with the Energy Star label. This label means that the windows meet strict energy efficiency guidelines set by the U.S. government.
