Check out what exactly makes a window energy efficient!
The Energy Star label is by far the most recognized symbol in energy efficient products. Perhaps most notable among these products are energy efficient windows. Windows and doors are historically the most notorious weak spots for inefficiency in a building's envelope. So, it's vital that new and replacement windows be as energy efficient as possible. That's where Energy Star comes in.
Administered by the U.S. Department of Energy and Environmental Protection Agency, the Energy Star program sets a standard for energy efficient windows that window manufacturers must meet to qualify as an Energy Star Partner. Once qualified, that manufacturer may then apply the Energy Star label to their product so that prospective buyers can easily pick out the energy efficient windows in a showroom.
550 individual window manufacturers create Energy Star-rated windows. A master list can be found at the Energy Star website. 550 is too many to list here, but realistically, you're unlikely to find 550 different window brands on your next trip to a window supply store. So I sought out a list of the most popular window brands - the brands you'll find in most any store - and surveyed them for Energy Star-rated windows.All of the top 15 window brands listed below qualify as Energy Star partners. This means that they all offer energy efficient windows that meet strict government standards for efficiency. The fact that every single top window brand in the country offers Energy Star products is a good sign for homeowners and the environment, and it'll make window shopping (pun intended) that much easier.
