According to the Window and Door Manufacturers Association, windows that are 20 years or older can make 5.3 tons more greenhouse gases per year than new windows. In fact, new windows are more energy efficient than windows that were manufactured just 10 years ago. The US Department of Energy says that you can save 10-25% on your energy bills with by installing modern, high efficiency windows.
Do you know if your current windows are ENERGY STAR rated?* Even if they met ENERGY STAR standards when they were installed, the government has actually raised their standards for granting this rating in the past 5 years, so it’s likely new windows would be an improvement.
Are your current windows single pane or double pane? If you have newer windows, chances are you have double pane windows, also known as insulating glass. They may have argon gas in between the panes, a feature that limits the temperature extremes that can be conducted through the glass, but with new windows, you can upgrade to krypton gas between the panes, which measurably improves upon the performance of argon. If you choose to replace your windows, Marvin offers tri-pane glass, which takes efficiency to new levels.
With more than 150,000 energy-efficient window and door options, along with the superior quality, Marvin is the industry leader in energy efficient windows.
* ENERGY STAR is a set of standards defined by the U.S. Department of Energy and the U.S. Environmental Protection Agency.
