When it comes time to replace your old windows, you can’t go wrong with fiberglass frames—but how much do fiberglass windows cost?
Even though fiberglass is considered a premium option, the total amount you’re likely to spend on your new fiberglass windows will largely depend on things like the size of the window, whether or not it’s a custom window, and how complicated the installation will be.
Let’s break down the details of fiberglass windows and everything that goes into the final price tag.
The Price Range of Fiberglass Windows

When you’re picking out new windows, some of the more premium choices can have a higher cost. But depending on what type of window you want and how customized you want it to be, fiberglass windows can be affordable.
Most fiberglass windows can range anywhere between $650 and $950 per window before installation or add-ons. The price range can shift depending on how big your windows are, whether you choose any custom features, and how complicated it will be to replace and install your new windows. For example, a standard double-hung fiberglass window might cost around $900, while sliding windows can be a bit more expensive at around $950.
Let’s explore the specific factors that affect the cost of fiberglass windows.
What Kind of Window Do You Want?

Fiberglass windows come in all different shapes, styles, and sizes—and each type of window has its own price point. A large fiberglass picture window that spans the length of your living room is going to cost much more than a small fiberglass single-hung window for a bathroom.
Custom features also play a big role here. If you need a specialty shape window (think quarter-circle or pentagon), you’re looking at a higher price point.
Energy Saving Features: Window Upgrades That Make A Difference

Fiberglass windows are one of the most energy-efficient options out there, but that can come with an added price. On top of that, you can also add upgrades to give your new fiberglass window even better chances against the elements.
And in terms of window glass options, windows that have multiple panes of glass, Low-E (low-emissivity) glass coatings, or gas-filled spaces between the panes (like argon gas) can make a night-and-day difference when it comes to your window’s insulation power. Just keep in mind that these features also raise the price.
If you’re choosing between a basic fiberglass window and one with triple-pane glass, you’re probably looking at an increase of about 15-20% more for the upgrade. Your new windows can make up for that added cost over time in the form of lower energy bills—especially if you live in a place like Nebraska or Iowa with extreme temperatures that regularly fluctuate.

Installation is another factor that impacts the total price of fiberglass windows.
Professional installation will usually run you anywhere from $100 to $300 per window, depending on the complexity of the job. If you’re dealing with a two-story home or windows that require special handling (like oversized or irregularly shaped ones), the installation price might be higher.
Are Fiberglass Windows Worth It?

You might be thinking, “Fiberglass sounds great, but why would I choose it over vinyl or wood?” Let’s take a quick look at why fiberglass could be worth the higher price tag.
If saving on heating and cooling bills is a major priority for you, then fiberglass should definitely be on your radar. Fiberglass windows are extremely durable and with proper maintenance can last for years since they don’t easily warp, crack, or expand—which is especially useful in Nebraska and Iowa, where fluctuating temperatures are the norm. Naturally, this makes fiberglass windows one of the most energy-efficient window options available because they keep a tight seal year-round.
Compare that to vinyl—which might start showing wear sooner—and wood—which requires slightly more maintenance to prevent rot and insect damage.
