Reduce Utility Bills with Energy Efficient Windows By Gary Milke
The quality of your windows can surprisingly impact the overall comfort of your home. From cold drafts in the middle of winter to blazing heat in the summer months, inefficient windows can not only impact your comfort level but also add to your heating and cooling costs. One way to enhance the comfort of your home and reduce energy costs is by installing energy efficient windows.
What are Energy-Efficient Windows?
An energy efficient window is one designed with at least two panes of glass to minimize heat loss while maximizing protection from outdoor elements. Energy efficient windows are typically coated to protect the interior of your home from the heat of the sun. Energy-efficient windows will also feature airtight frames and have an ENERGY STAR® rating.
According to ENERGY STAR, windows that are ENERGY STAR qualified can reduce energy bills by 7-24 percent. Not only will energy efficient windows reduce energy bills, but they’ll also increase the overall comfort of your home.
How to Choose Energy-Efficient Windows
When shopping for energy efficient windows, look for windows that are ENERGY STAR qualified for your region. If ENERGY STAR qualified windows are not available, look for windows designed with double or triple pane glass. For maximum efficiency, the glass should be E- coated to provide additional protection against the elements of the outdoors.
The frame of a window also plays an important role in the overall efficiency of a window. Energy efficient windows should feature insulated vinyl or fiberglass frames as these typically provide the greatest efficiency in cold and warm climates. Vinyl and fiberglass frames typically have less heat loss than traditional wood frames.

The U Factor of a window helps determine the overall efficiency of a window. ENERGY STAR recommends individuals living in cold climates utilize energy efficient windows with a U Factor of 35 or less. Those living in warmer climates should look for energy efficient windows with a U Factor of 40 or less. The lower the U Factor the more efficient a window is.
Proper installation can also impact the overall efficiency of your windows. Be sure to work with a qualified window installer who will follow the manufacturer’s instructions for installing energy efficient windows.
