Energy Efficient Features to Look For When You're Replacing Your Windows

Replacing your windows can be a cost-effective way to reduce your energy bills and carbon footprint at the same time. Windows play a critical role in keeping your home comfortable, but they can also be a source of heat gain and loss, depending on the season.

If you’re planning to replace your windows soon, it’s essential to consider the energy efficiency features that will make a significant impact on your home’s energy performance. Explore some of the energy-efficient features you should look for when you’re shopping for new windows.

Low-E Glass

Low-E (low emissivity) glass has a special coating that reflects heat back into the room during the winter months and blocks heat from the sun during summertime. This means that it can help reduce your energy bills by preventing heat loss during the wintertime and reducing your cooling needs during the summer months.

Insulated Frames

Materials like vinyl and fiberglass are excellent insulators and can prevent heat transfer between the inside and outside of your home. The frames around your windows play an important role in the overall energy efficiency of your windows, so it’s worth considering your options.


Gas-filled windows have an inert gas, usually argon or krypton, between the panes, which helps reduce heat loss. This feature can add a layer of insulation to your windows and make them more energy-efficient.

Multiple Panes

Double or triple-pane windows have multiple layers of glass with a layer of gas or air in between. The extra layer of glass provides added insulation and can help reduce heat loss and gain throughout the year.


Weatherstripping is an essential component of any energy-efficient window. It’s a durable material between the sashes and frames that prevents airflow and drafts. Check for weatherstripping when choosing new windows to make sure that your windows are as energy-efficient as possible.

If you’re looking for a way to save money on your energy bills and reduce your carbon footprint, replacing your windows with energy-efficient ones is an excellent place to start. Look for windows that have low-E glass, insulated frames, gas filling, multiple panes, and weatherstripping. These energy-efficient features will help keep your home comfortable year-round and will save you money on your energy bills in the process. By making energy-efficient choices with your windows, you can improve the overall comfort and energy performance of your home.
