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-pane windows, 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 – 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 – 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.
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.
Sound-Proof Triple-Pane Windows
Triple-pane windows are more effective at keeping out sound than single or double-pane windows. This particularly beneficial if you live in a city or some other noisy environment. For some, this advantage can be worth the extra cost of the windows on its own. Check out some of the best soundproof windows.
