Double-pane windows, also known as dual-pane or double-glazed, are the standard in most current homes, with an average cost of $234–$1,224. 

These windows are designed with a small gap of space between the two parallel glass layers that can be filled with gas, typically nontoxic krypton or argon, to form a thermal barrier and reduce heat transfer. How much you spend depends on a few factors, such as window style, material, glass type, brand, and energy efficiency features. 

Our guide breaks down how these factors affect your total cost, plus where to compromise versus where to invest to get the best window option at the best price. We collected data from RSMeans, respected window associations, leading window companies, and our internal survey of 1,000 homeowners to give you a sense of what to expect when shopping for window replacement options.

What Are the Benefits of Double-Pane Windows?

Double-pane windows also offer long-term durability, with an average life span of up to 20 years, according to the International Association of Certified Home Inspectors (InterNACHI). Most homeowners today opt for at least double-pane windows due to their increased energy efficiency. Our survey of 1,000 homeowners showed that 56.1% of respondents chose double- or triple-pane windows for their latest replacement. The more panes in your window’s design, the better it can control heat transfer, air leakage, and noise pollution. This means your home will not only be more comfortable, but your HVAC system won’t have to work as hard to regulate your home’s temperature, resulting in lower energy bills.

The Department of Energy reports that heat gain and loss through poor-performing windows are responsible for 25%–30% of residential heating and cooling energy use, so investing in multi-pane windows can go a long way in reducing your energy expense. Though triple-pane windows offer the best insulation due to three window panes, they are more expensive. Upgrading to double-pane windows provides a good balance between energy efficiency and affordability for most homeowners.


Which Factors Affect Double-Pane Window Costs?

While your total cost for a double-pane window replacement will likely be in the $234–$1,224 range, several choices you make when deciding on your windows will greatly impact the cost. These selections can affect your final cost by hundreds or even thousands of dollars:

  • Window style
  • Window material
  • Glass type
  • Brand
  • Energy-efficiency features
  • Installation labor

How Much Do Double-Pane Windows Cost by Style?

There are over a dozen popular window styles to choose from. Whether you’re replacing your window with the same style or trying out a new look, your chosen window type comes with its own price tag, no matter the number of panes. A standard-size, double-hung window, for example, is far more affordable than a large window style such as bay windows. The larger the window and the more complex the design and installation, the higher the price.

How Much Do Different Window Frame Materials Cost?

The window frame material you choose is another major cost factor. You can choose between aluminum, composite, fiberglass, vinyl, and wood framing.

Window material is one area not to skimp on when choosing your windows. It can make a big difference in how well your window performs and how long it lasts, so the goal is to balance your budget with the material that has the look you want and the efficiency your climate requires.

Pros and Cons of Each Window Frame Material

Each material has its own pros and cons.

Aluminum is both strong and lightweight, and it resists bending and warping. However, it’s not energy-efficient and is prone to rusting. 

Composite windows, which are made from wood fibers and polymers, are low-maintenance and energy-efficient, but the quality can vary significantly based on the workmanship of the manufacturer. 

Fiberglass windows are highly durable and energy-efficient, but they’re vulnerable to UV ray damage. If they get a lot of direct sun, they’ll likely fade quickly.

Vinyl windows are common in homes today due to how durable and low-maintenance they are. However, they’re also prone to fading and don’t come in many color options, so if curb appeal is a priority for you, they may not make for the best choice. 

Wood windows are attractive and energy-efficient, but they can warp and rot, especially in humid or rainy climates.


How Much Do Different Glass Types Cost?

When choosing glass for your window, you’re not just choosing the number of panes but also any glass treatments. Three common specialty glass options are frosted glass, laminated glass, and tempered glass. 

  • Frosted glass ($92–$627): Frosted glass allows sunlight to travel through your window while blurring the view into your home. 
  • Laminated glass ($355–$865): Laminated glass options contain resin for added durability, making it up to five times stronger than normal glass. 
  • Tempered glass ($335–$595): Tempered glass is made to resist impact, such as flying debris during extreme weather or a blunt object in the case of a break-in.

Unless you have a need for added protection or privacy, there’s no need to add this expense.


Which Window Brand Is the Most Affordable?

Window brands can have pricing not even in the same ballpark, no matter how similar the product is. We’ve reviewed many leading window manufacturers and learned that brands price their products and services differently due to varying years of experience, industry certifications, awards, product selection, warranty coverage, and other factors they feel set them apart. A well-known national brand with a long history, such as Renewal by Andersen, is likely to charge more than a local company you find online. 

Here’s an idea of the cost you can expect per window with top brands. All major brands make double-pane windows. We recommend going with the company that has the style, materials, and warranty coverage you want without going over your budget. We suggest reading customer reviews online before deciding on the brand to purchase from.

How Much Do Energy-Efficient Double-Pane Windows Cost?

Energy efficiency is a major area not to cut costs on. Choosing double- over single-pane windows is already a step in the right direction to improve energy performance. A few other selections can drastically enhance your windows’ energy efficiency, such as:

  • Argon gas filling ($115–$2,436): This is a nontoxic gas injected between layers of glass during manufacturing to add further insulation. 
  • Low-emissivity coating (107–$2,400): A low-e coating can be applied to the window glass to help with heat transfer, keeping your home warmer in winter and cooler in summer. 
  • Triple-pane glass ($700–$1,050): If you want to take energy performance even further, opt for triple-pane glass. This is most recommended for northern climates with harsh winters. 

The biggest thing to look for when buying windows is an Energy Star label. According to Energy Star, using its certified windows lowers your household energy bills by an average of 12% per year. Energy Star windows are independently tested for performance across U.S. climates and are recommended by the U.S. Environmental Protection Agency. Energy Star products are also tested independently by the National Fenestration Rating Council, a nonprofit organization that grades windows’ insulation and efficiency performance. Look on the Energy Star label for windows recommended for your climate to get the most bang for your buck. 

Major brands are Energy Star partners and already incorporate performance enhancers such as low-e coating and argon gas filling into manufacturing, so getting these features won’t vary your cost too much. Choosing an Energy Star-certified window over one that isn’t will add to the initial price, but your return on investment will be better considering how much an efficient window will save you over time.


How Much Do Double-Pane Windows Cost to Install?

Double-pane windows are typical, so most installers don’t charge any extra to install them compared to single-pane windows. Instead, installers charge varying rates based on their experience and credentials as well as the complexity of the installation. Budget for around $36–$153 per window. More complex installations, such as specialty-shaped windows or large styles, can increase labor costs.

Can I Install Double-Pane Windows Myself?

You can install double-pane windows yourself, but we don’t recommend it. Depending on the size and location of the window, do-it-yourself installation can be dangerous. The job also may be trickier than you think. Not done well, you could end up with air leakage and moisture issues that become a more expensive hassle than just paying for a professional installer from the start. Many window manufacturers void warranty coverage if your windows aren’t installed by a licensed professional, so we recommend investing a little more for a pro so you don’t run into issues.

We had a team member accompany a Renewal by Andersen installation crew to learn what an expert team provides homeowners. Most installers prep your home by laying down drop cloths to protect the workspace. They bring all equipment and securely install and seal your windows before fully cleaning up the job site and disposing of your old windows and materials. Take a look at our guide detailing what to expect on your window installation date.


You can shave a little more off the cost of your double-pane windows with these tips:
Apply for a federal tax credit: There’s a tax credit for installing Energy Star-certified windows and skylights. You can claim up to 30% of installation costs for a maximum credit of $600. This credit applies to your primary residence and is available from January 2023 to December 31, 2032. 
Buy in bulk: If you need to replace multiple windows, buy as many as you can afford at once. Many companies will give you a discounted rate for buying in bulk. Plus, you won’t have to pay an installer to come out multiple times. 
Consider compromising: We recommend spending the bulk of your budget on energy features and quality materials but consider changing your selections in other areas if you’re over budget. For example, if you want a large window that lets in a lot of natural light, go with a picture window over a bay window. Don’t splurge on tempered glass unless it’s something you think you really need.

Retrofit Replacement Cost vs. Full-Frame Cost

If you’re looking to replace a window due to damage to the glass, for example, there’s no need to pay for a full-frame replacement. Instead, you can just get a retrofit replacement. Retrofitting uses the existing window frame and trim and only removes the window sash, so it can save you considerably in material and installation costs.


Are Double-Pane Windows Worth the Cost?

Opting for double panes, as well as other energy performance enhancers, is a wise investment. Most double-pane windows end up costing a few hundred dollars, but the choices you make beyond the number of glass panels have a lot to do with your total expense. Focus your budget on performance first, then appearance and customizations. 

The best way to see what double-pane windows will cost you is to choose a few brands that meet your criteria and get a quote to compare pricing.

FAQs About Double-Pane Window Costs

Are double-pane windows worth the cost?

Double-pane windows are worth investing in because they provide more insulation and therefore better energy performance than single-pane windows. You’ll pay more up-front but have a higher return on investment thanks to energy savings.

How much does it cost to upgrade to dual-pane windows?

It typically costs anywhere from $234–$1,224 to upgrade to dual-pane windows, though your expense can vary depending on the window type, material, glass, brand, and features you choose.

Can you replace one pane of glass in a double-pane window?

Whether you want to replace one pane due to glass damage or to increase performance, you need to replace both panes of glass for the window to work effectively. Replacing just one pane of glass will affect the window’s sealing ability, letting in air and hurting energy efficiency.

How long do double-pane windows last?

Double-pane windows can last 10–25 years. How long your windows last depends on the quality of materials and installation, as well as how well you maintain them.
