Triple-Pane Window Cost Breakdown

Additionally, larger or custom windows, premium materials like fiberglass or wood, and upgrades such as UV-blocking coatings can raise the price.

Overall labor costs will depend on how many windows, the type of window you’re installing, and the size of your windows.

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 |

| Wood | $1,100 |
| Composite | $1,450 |

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 |
DIY vs. Hiring a Pro to Install Triple-Pane Windows
If you plan to install triple-pane windows yourself, you can expect to pay between $300 and $2,740 for each window. You’ll save between $100 and $800 on labor costs. That said, it’s usually best to leave this job to a professional.
Because the primary reason to install triple-pane windows is to improve energy efficiency, doing a sub-par job can negate any future energy savings. If you’re interested in triple-pane windows, reach out to a window replacement company near you to discuss your options.

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.

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.
