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 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.

How Much Do Triple Pane Windows Cost?

The average cost for a replacement triple pane window installation is $550 to $850 per triple paned window + labor  costs which can average around $38 per hour depending on your local window installers average price.

Because of the additional pane of glass and more complex construction and installation, you can expect to pay at least 10 to 15% more 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.

Double Pane vs. Triple Pane Windows

If you’re having trouble deciding between replacement double pane or triple pane windows, you’ll need to consider the potential insulation improvements. Just take a look at double and triple pane windows and you’ll 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 their Energy Star rating.

An increase in energy efficiency conversely means a decrease in heating bills. A home in an area like New England can save up to 2-3% on heating bills with triple pane windows compared to a home with double pane windows
