What Are Energy-Efficient Windows?

Energy-efficient windows, alternatively referred to as energy-saving windows, are designed to keep heated or cooled air inside your home. Their increased insulation helps to reduce your home’s energy consumption—and thus your utility bills! —while also increasing the overall comfort of your home.

Are Energy-Efficient Windows a Good Investment?

Whether or not efficient windows are worthwhile depends entirely on the type of windows being replaced. If, for example, you have single-pane windows with warped wood frames, you’re likely to see a noticeable difference in your utility bills. However, the majority of homes are unlikely to be in this situation. The majority of the leading residential window manufacturers will offer energy-efficient upgrades.

Many homes already have double-paned windows, and the energy savings associated with replacing them with ENERGY STAR-rated products are much smaller. According to the Department of Energy, a window installation will save you between $27 and $111 per year, which means that it will take much longer to recoup the cost of your initial investment in new windows.

However, energy savings are not the only factor that should be considered when determining a new window installation value. Additionally, new windows increase the value of your home. Indeed, installing new vinyl windows can add up to $12,000 to the selling price of your home, making them an extremely wise investment if you’re about to list your property or intend to sell soon.

How Do Energy Efficient Windows Work?

As our world moves toward energy conservation and efficiency, home improvement can become a little perplexing. Particularly for windows, because they appear identical to other windows, many people wonder how they differ from other windows and what benefit there is to replacing windows. Apart from lower heating and cooling bills, there is a significant technological component to how energy-efficient windows work. In order to help you understand how modern window technology works, a compiled list of some energy-efficient features that will keep you cooler in the summer and warmer in the winter are explained below.

Glass coating

 Low-E glass, also known as Low-emissivity glass, is used in energy-efficient windows to help block the sun’s rays (up to 90%) and keep the heat inside when it’s cold and outside when it’s hot. Additionally, there are numerous glazing options, including tints, gas fills, and reflective coatings. Again, all of these are used to assist you in lowering your heating and cooling costs.

Spacer systems

Instead of metal, 100 percent polymer structural foam is used as a window insulation material to keep the windows thermally stable and condensation-free. Most companies use the Super Spacer®, which reduces the U value, or rate of heat loss, by.01. The lower the U value of the window, the more efficient it is.

Window technology

The use of gas and multiple panes of glass are two of the most recent window technologies. Double- and triple-paned glass both increase the number of UV rays blocked. With a triple-paned glass window, up to 97 percent of UV rays are blocked, ensuring year-round comfort and preventing fading of fabrics, flooring, and other personal belongings. Another excellent energy-efficient window technology is Krypton gas’s addition to the space between the insulated glass to reduce heat transfer further.

If windows are not equipped with the coating, proper glass, and spacers, they can act as a thermal hole. According to some estimates, one-third of the money spent on heating and cooling goes straight out the window. However, with the numerous new technologies available for energy-efficient windows, all you need to worry about is getting your old windows replaced! You can be certain that you will immediately begin saving money and achieving a more energy-efficient home in general.
