How Much Do Triple Pane Windows Cost?

The main draw back with triple pane glass replacement windows are they are a bit more expensive in price, although the amount of increased insulation versus the cost can more than pay for itself over time in energy bills.

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.


National Average for Triple Paned Window Replacement Cost:

$550 – $850 (including installation costs.)

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.

Double Pane vs. Triple Pane Windows

Pros: 

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

More Sound Proof

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.

Better 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’re ready to leave.

Cons:

As discussed earlier the main issue with triple paned windows is the cost. If you need an accurate measurement of the cost of replacement triple pane glass windows use our windows cost calculator here.


Things to Consider:

Choosing a Quality Spacer

Though the gas pockets between panes provide excellent insulation, heat moves through the spacers, which limits a window’s potential energy efficiency. If you’re buying triple pane windows, make sure to get a “warm edge spacer”. These are more effective at slowing heat down and, therefore, make your windows more efficient.

Getting an Upgraded Window Gas

Switching to a gas with a higher insulating factor—like argon or krypton—can make a noticeable difference in your window’s insulation. Argon gas is the most commonly used insulating gas because it’s clear, odorless, and most importantly, non-toxic.

Krypton has those same qualities, but it provides an even higher level of insulation. Triple pane windows provide two pockets for gas, so you can have them both filled with whichever gas you choose.

More Protective Coatings

If you’re shopping for windows, you may hear about low-e coatings, which are designed to reflect heat back into the home when it tries to escape. Since only one coating can be added to each section of glass, triple pane windows offer more potential layers to coat, meaning more insulative protection for your home.

Triple pane windows are modern upgrades to double pane windows. Both options offer marked improvements over single pane windows, and almost every style of window today comes with double or triple pane glass depending on your preferences.
