Your windows are an important component of every room. They let natural light into your home, enable you to enjoy a cool breeze when the weather’s nice, and allow your cat to bird-watch on demand.

The main factors that influence the cost of triple pane windows are materials and labor.

Number of Windows

The number of windows you'll need will significantly impact your total costs. For example, a home with 20 windows will cost $6,000 to $54,800 for materials and an additional $2,000 to $6,000 for labor. 


Triple pane windows typically cost $300 to $2,740 per window. Wood-framed windows are usually more expensive than windows with vinyl or aluminum frames. Larger size windows also tend to be more expensive.

Window Type

Large windows will naturally cost more than average-sized windows. 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. Bay windows and large picture windows can cost up to three times more than average windows. 


Labor costs for installing triple pane windows range from $100 to $800. Overall labor costs will depend on how many windows you’re installing and the size of your windows. Labor costs also vary depending on whether you’re installing the windows on the ground floor or an upper story. It can take up to an hour longer per window for upper-level installation.


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. 

First, Second, or Third Story

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. 

How Much Does It Cost to Install Triple Pane Windows Yourself?

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, you’ll want to reach out to a window replacement company to discuss your options.


Do triple pane windows help with condensation?

Yes, triple pane windows are more resistant to condensation. They help to reduce interior condensation that forms as a result of warmer temperatures inside your home than outside it. This makes them a good fit for cooler climates, particularly with newer, well-sealed homes that retain higher levels of moisture in the winter months.

Are triple pane windows more expensive?

Yes, triple pane glass windows cost more than double or single pane windows. You’ll eventually get that money back in energy savings. Depending on how much you pay for the installation, you could recoup your costs in 10 to 20 years

Are triple pane windows quieter?

While some homeowners are under the impression that triple pane windows can help to reduce sound, the truth is that triple pane windows will not be much quieter than double pane windows since having a third pane doesn’t make much difference in sound transmission. If you’re looking to reduce sound, you should consider installing laminated glass windows.

When should I install new windows?

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all of your windows at once

When buying new windows, you should consider energy efficiency, safety, and aesthetics in order to choose the window that’s right for you.

How do I hire a window replacement contractor?

If you’re looking to hire a window replacement contractor, the first step is to solicit quotes from multiple different companies. This will help you to get a sense of how much the project will cost and to select a contractor that meets your budget. 

Be sure to read the fine print of your contract, verify your contractor’s references, and check their license before hiring them to complete a window installation project.
