What Are Triple Pane Windows?

Triple pane windows — the most advanced windows on the market today—are made with three panes of glass. As with double paned window, each of the 3 panes has a spacer around the edges to give them a uniform space between layers. A seal between each pane makes the windows airtight and allows for pockets of gas to fill the space for improved insulation and makes for a more energy efficient window.

Double Pane vs. Triple Pane Windows

If you are having trouble deciding between new double pane window installations or triple pane windows, you will need to consider the potential insulation improvements. Just take a look at double and triple pane windows and you will see that the U-factor (rate of heat loss) is better in the triple pane glass option, making them the better insulator.

The most obvious benefit of triple pane windows is an increase in energy efficiency—they offer an improvement of up to 20% to 30% on energy efficiency if you consider Solar Heat Gain Coefficients (SHGC) and U-factors. While these statistics will vary according to where you live and the exact windows your home has, you can find out more about your windows’ energy efficient performance by checking out Energy Star window ratings associated with a thermal window installation.

Because of the additional pane of glass and more complex construction and installation, you can expect at least 10% to 15% more in installation cost for triple pane vs double pane windows. It is estimated it can take a homeowner up to 30 years or more to fully recoup this amount through energy savings and payments.

An increase in energy efficiency conversely means a decrease in energy bill costs. In a March 2021 Modernize survey, 40 percent of homeowners said they are actively pursuing home improvement projects to save money on their utility and electric bills. A home in an area like New England can save up to 2% to 3% on heating bills with triple pane windows, compared to a home in the same area with double pane windows. This can lead to significant long-term savings for homeowners.

More on Insulation

Because of their advanced insulating properties, triple pane windows are better at regulating your home’s temperature at a comfortable level. This affects your expended energy and monthly energy bills, but also your relationship to your home. For example, if you have a favorite spot next to the window in your favorite chair, single pane windows can limit your time here, but triple pane windows will allow you to stay comfortable and warm in your spot until you are ready to leave. Most of the top replacement window brands will offer a triple pane glass option for their different window styles.
