Double-Pane Windows Cost Factors: What Determines the Price?
Double-pane windows can cost anywhere from $150 to $7,000, and where your total lands within that range depends on a few key factors—frame material, window style, size, and glass type among them.

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 style directly affects what you'll spend, with price driven by the window's size and shape, the complexity of its opening and locking mechanisms, and how difficult it is to lift into place. Windows with operable sashes consistently cost more than fixed options because of their added mechanical complexity.
See the table below for more details about the different styles of double-pane windows and their costs:
| Window Style | Window Cost |
|---|---|
| Single-hung | $200–$900 |
| Double-hung | $250–$1,100 |
| Sliding window | $250–$1,200 |
| Casement window | $250–$2,000 |
| Picture window | $170–$1,000 |
| Hopper window | $150–$600 |
| Bay window | $700–$6,000 |
| Bow window | $1,600–$7,000 |
Size
Larger double-pane windows cost more to install, and you can expect to pay between $75 and $110 per square foot regardless of style. Stepping outside standard sizes into custom dimensions adds further cost through additional manufacturing materials and increased labor. Sticking with standard sizes is one of the most reliable ways to keep your total toward the lower end of the range.
The table below outlines what you’ll pay for a double-pane window based on its size:
| Window Dimensions (Ft.) | Installation Cost |
|---|---|
| 2-by-1 | $150–$220 |
| 2-by-3 | $450–$700 |
| 3-by-2 | $450–$700 |
| 3-by-4 | $900–$1,300 |
| 4-by-3 | $900–$1,300 |
| 4-by-4 | $1,200–$1,800 |
| 4-by-6 | $1,800–$2,600 |
| 5-by-3 | $1,100–$1,700 |
| 6-by-4 | $1,800–$2,600 |
| 7-by-5 | $2,600–$3,900 |
| 8-by-5 | $3,000–$4,400 |
| 8-by-8 | $4,800–$7,000 |
| 10-by-6 | $4,500–$6,600 |
Number of Windows
The number of windows you install affects your per-unit cost, since most contractors discount the per-window price as volume increases. For example, a single window might run $1,000, but that per-window price can drop to $900 or less when you replace all the windows in your home. Because your installer is already on site for a multi-window job, they save time and pass those savings on to you.
Here’s what you’ll pay based on how many windows you’re installing:
| Number of Windows | Average Cost |
|---|---|
| 3–4 | $3,000–$4,000 |
| 5–10 | $4,750–$14,250 |
| 11–20 | $9,900–$18,000 |
Glass Type
Double-pane glass is itself a form of insulated glass, but you can upgrade to specialty glass types that improve security and privacy at an added cost to your window replacement cost. These upgrades can make your home safer and more comfortable, though your final cost will vary based on window size, style, and frame material.
Below are the different types of window glass you can choose from aside from opting for insulated glass:
| Glass Type | Cost Per Window |
|---|---|
| Frosted glass | $450–$1,100 |
| Laminated glass | $400–$950 |
| Low-E glass | $500–$1,400 |
| Tempered glass | $300–$1,000 |
Window Brand
The brand you choose affects your double-pane window cost because brands differ in quality, longevity, and warranty coverage. Higher-quality brands often last longer and offer stronger warranty protection, but carry a higher up-front price. Budget brands lower your initial cost but may cost more over time through earlier replacement needs or higher energy bills if they are less efficient.
The prices below are averages, so costs can increase for larger windows, more complex designs, and higher-quality frame and glass materials:
| Brand | Window Cost |
|---|---|
| Alside | $150–$1,800 |
| Andersen | $250–$3,500 |
| Castle | $200–$2,000 |
| Champion | $200–$2,200 |
| Feldco | $150–$1,500 |
| Harvey | $200–$2,200 |
| Marvin | $250–$4,000 |
| Milgard | $250–$4,000 |
| Pella | $150–$3,500 |
| Ply Gem | $150–$1,800 |
| Simonton | $200–$2,000 |

How to Save Money on Double-Pane Windows
Double-pane windows will save you money on utilities over time, thanks to their improved insulation properties compared to single-pane windows. However, that added efficiency means these windows come with a higher up-front cost. Don't worry, though—there are several things you can do to keep the cost of double-pane windows down.
Shop in the off-season: Need new windows? You can get deals by shopping in the off-season when window installation companies are normally in a lull.
Opt for standard sizes: Unless you really want a custom window, shop for smaller, standard-sized windows to save money on materials and installation.
Replace multiple windows: You can get deals on the per-window price and the cost of installation by buying in bulk and replacing more windows at once. Your total will, of course, be higher, but you'll save a bit on each window.
Skip the extras: Double-pane windows offer great insulation, so you may not need to add the cost of other upgrades, like low-E window films or window tinting.
Next Steps: Finalize Your Project With a Pro
Book an appointment to have your windows professionally measured.
Tell your window installer about your goals for things like efficiency and noise reduction.
Get a quote for professional window framing and finishing that you can compare to DIY costs.
If your budget allows, consider enhancing energy efficiency with add-on options such as low-e glass or specialized coatings that seal windows.
