Composite and fiberglass frames are the most expensive frame options, running up to $1,800, two to three times as costly as aluminum and vinyl.
Triple-pane windows on the second floor will cost 5% to 10% more to replace due to reduced accessibility.

The average cost to install triple-pane windows runs about $1,950, though it can range from as low as $300 per window to as high as $3,000. But the price comes with some big benefits. Triple-pane glass windows, also sometimes known as triple-glazed windows, are more insulated, so they keep your heat or air conditioning from escaping. This translates into lower utility bills. Triple-pane windows are also more resistant to condensation and will generally provide a higher level of comfort in your home.

From one homeowner to another
I had a kitchen window shatter from it being -20 degrees and was able to call them in to get it inspected quickly. When it was time to install the new glass Mr. Jeremy Glass was had been in communication with me to let me know his ETA, was able to replace the section of broken glass, and was able to re-install the window in the correct way vs how the house flippers before me decided to install it. Mr. Jeremy Glass was friendly, professional, and able to get everything done in less than 30 minutes.

Window Size

Large windows will naturally cost more than average-sized windows, and triple-pane windows cost about $25 to $40 per square foot. Triple pane windows need extra care during the assembly process, and, with increased size, they also require more materials. The same is true of uniquely shaped triple-pane windows. Large picture windows and bay windows cost up to three times more than average windows.
| Window Size (Inches) | Average Cost per Window |
|---|---|
| 24 x 36 inches | $150–$240 |
| 24 x 48 inches | $212–$340 |
| 32 x 48 inches | $275–$440 |
| 32 x 62 inches | $355–$570 |
| 48 x 60 inches | $500–$800 |
| 60 x 36 inches | $375–$600 |
| 72 x 48 inches | $600–$960 |
Materials
Triple-pane windows cost $300 to $2,740 per window on average. Wood-framed windows are usually more expensive than windows with vinyl or aluminum frames. Larger size windows also tend to be more expensive.
| Material | Average Cost |
|---|---|
| Aluminum | $725 |
| Vinyl | $900 |
| Wood | $1,100 |
| Composite | $1,450 |
| Fiberglass | $1,800 |
Number of Windows
The number of triple-pane windows you'll need will significantly impact your total costs. For example, a home with 20 windows will cost $6,000 to $60,000 for materials and an additional $2,000 to $6,000 for labor. If you plan to replace all windows at once, you may spend more upfront, but you also might be eligible for discounts for buying in bulk.
| Number of Windows | Cost |
|---|---|
| 1–5 | $300–$15,000 |
| 5–10 | $1,500–$30,000 |
| 10–15 | $3,000–$45,000 |
| 15–20 | $4,500–$60,000 |
Spacer
The term "spacer" refers to the gas or material between multiple panes of glass. A spacer helps aid in insulation and noise reduction. A higher quality spacer gas or material will affect the overall price per window.
Location
When creating a budget for your project, you'll need to consider the location of your windows. Windows on second stories and higher require more safety precautions and care. Usually, this results in additional time and thus an increased labor cost. You can safely assume that most upper-level windows will take at least an extra hour to install.
Window Extras
Although triple-pane windows already improve the insulation and efficiency of your windows, you can also opt for added treatments or coatings that further improve insulation, block UV rays, or increase soundproofing qualities. These window extras will increase the cost of each window.
You can buy decorative, UV-blocking, or privacy film that clings onto your windows for about $15 to $100. Low-E coatings add about 15% to triple pane windows costs while choosing windows with air or gas-filled panes for better efficiency will cost about $120 to $1,200 per window.
Double vs. Triple-Pane Windows
Double and triple-pane windows differ in the number of glass layers they contain. Double-pane windows have two layers of glass separated by a sealed airspace, providing moderate insulation. On the other hand, triple-pane windows have three layers of glass with two sealed airspaces, offering superior insulation and soundproofing. Triple-pane windows are more energy-efficient and can help reduce heating and cooling costs, making them a popular choice for homes in extreme climates or areas with high noise levels. However, they are typically more expensive than double-pane windows.
| Window Type | Average Cost (Per Window) |
|---|---|
| Double-Pane | $150–$1,000 |
| Triple-Pane | $300–$3,000 |
How to Save Money Installing Triple Pane Windows
Triple-pane windows are a worthwhile investment, especially because they offer cost-saving insulation plus provide some natural soundproofing from the noisy outdoors. Still, you can lower triple-pane windows costs with a few simple tips.
Consider Buying in Bulk
Some companies will offer discounts for buying more windows, and you may save on labor by replacing all your windows at once.
Get Multiple Quotes
Don’t settle for the lowest offer. Instead, look at multiple offers and consider the total value of each quote. Some quotes may cost a little more but provide better windows or more extras.
Stick to Standard Sizes
Unless you really want a custom window for your reading nook, save money by purchasing windows in standard and smaller sizes.
Replace Windows With the Same Sizes
Enlarging a window or creating new window openings significantly increases costs. Instead, install new windows in existing openings.
Shop in the Off-Season
Start browsing for off-season deals on your triple-pane windows in the wintertime.
