Vinyl, wood, aluminum, fiberglass… These are probably the first terms that come to mind when considering window frame materials, right? Which one’s the best for my windows? Which one’s more energy-efficient? Which one’s more durable? Well, today we’re going to talk about fiberglass windows, as there’s a bit of controversy regarding them. Why fiberglass windows are not popular is a common question that comes to mind, given that vinyl, wood, and aluminum are incredibly more common than other window materials.
After all, do fiberglass frames deserve to be shaded by other window materials? If they do, why? If they don’t – yet again, why? We’re here to find out, so keep reading!
Key Takeaways
- Fiberglass windows are durable, energy-efficient, and require minimal maintenance, lasting 30-40 years.
- One of the disadvantages of fiberglass windows is their high initial cost and limited availability.
- Fiberglass windows are susceptible to fading if not equipped with a special coating, are prone to water build-up over the years, and can’t have their corners welded.
What Are Fiberglass Windows?
Fiberglass windows are made by weaving glass fibers (consisting of silica-based materials) into a mat and coating them with resin. The material is then cut into window frames, which are then assembled into a window unit.
This combination of glass fibers and resin yields a robust and durable material that is energy-efficient and weather-resistant. That’s why fiberglass windows are resistant to warping and cracking, which makes them superior to, let’s say, vinyl windows.
Advantages of Fiberglass Windows
Given the details mentioned above, it’s clear that fiberglass has numerous advantages – what else can we expect from a window besides being energy-efficient, weather-resistant, and durable?
Let’s discuss all these aspects in detail, and then we’ll see if there’s any disadvantage that makes fiberglass not as commonly used as other materials in the window industry.
Durability
Fiberglass windows generally last 30-40 years, outlasting many other window materials.
Fiberglass windows are:
- Resistant to warping and cracking
- Resistant to fading and discoloration
- Resistant to rot and rust
- Resistant to mold
For comparison purposes – vinyl windows last only approximately 20 years; aluminum windows can reach a lifespan of 30-40 years, but they’re not energy-efficient; wood windows may also reach 40 years in lifespan, but only if maintained properly.
Another material you may want to consider if you’re weighing the pros and cons of each is Magic’s Hybrid Fusion Frame. We combine vinyl, aluminum, and steel to yield a superior frame material in terms of energy efficiency and durability. Our frames can sometimes perform well even past their expected lifespan of 40 years.
Maintenance
Another major advantage to take into account is maintenance – fiberglass windows don’t require regular painting or another type of maintenance. You just have to clean them once in a while using water and a mild detergent. If your house has many windows, this advantage can definitely reach the top of your pros and cons list!
Energy Efficiency and Aesthetics
Fiberglass is an excellent material when it comes to energy efficiency, as it has a low thermal conductivity. In simple terms, this means it doesn’t transfer heat and cold easily, so fiberglass windows can help you keep indoor temperatures steady.
In addition, fiberglass is often preferred above other window materials because it looks good. Thanks to their durability, fiberglass frames are thinner than others on the market.
Eco-Friendliness
People often believe that fiberglass is not environmentally friendly. Its production and disposal can indeed be quite challenging. But it is possible to recycle fiberglass successfully if appropriate measures are taken. Furthermore, fiberglass windows can also help you limit your energy consumption due to their excellent insulation properties. This further contributes to sustainability efforts.
Cons of Fiberglass Windows
Now that we’ve covered the advantages of fiberglass frames – which, without a doubt, make them a worthy investment – what about the downsides? What makes fiberglass windows unpopular in Canada?
Like any other material, fiberglass has some disadvantages as well – they may or may not be worth considering depending on your preferences and needs.
Higher Initial Cost
The primary reason fiberglass frames aren’t as popular as other window frames is their cost, which can be a problem if you don’t want to or can’t spend too much on windows. Fiberglass windows cost 10%-30% more than vinyl windows.
However, this higher upfront cost can be justified by long-term benefits. They offer better insulation, leading to significant energy savings over time. Additionally, they may also increase property value, so they can be cost-effective in the long run.
Limited Availability
Fiberglass windows aren’t as readily available as, let’s say, vinyl windows. That’s why you may have to wait longer for them to be manufactured, delivered, and installed. If you need a quick window replacement, this may be an inconvenience.
Professional Installation Requirement
In terms of installation, vinyl windows, for example, are easier to install than fiberglass windows because the latter are more rigid. While you can install vinyl windows yourself if you have some experience in installing windows, you’ll likely have to seek professional help with fiberglass windows. This can further increase the final price.
If the windows are installed improperly, you can say goodbye to energy-efficiency and high performance, unfortunately. This can lead to drafts and water leaks, which, in turn, can lead to structural damage over time. Therefore, trained professionals should handle the installation process, especially in older or custom-built homes where it’s even more difficult to fit the units into the window opening.
Susceptibility to UV Light
Fiberglass windows are susceptible to UV light, which can cause fading and damage the frames over the time. However, they can be manufactured with protective coatings that prevent degradation caused by UV exposure. But this translates into additional costs.
No Weep Holes!

Weep holes are tiny openings at the bottom of the frame allowing the water that has accumulated within the frame to escape the structure. Without weep holes, the water simply builds up within the frame, which can lead to water damage over time.
Unfortunately, fiberglass windows often come without weep holes. Even if they do have weep holes, they aren’t enough to prevent clogging. This can be a concern if you live in a region with frequent rain storms or high humidity.
Fiberglass Windows Can’t Have Their Corners Welded
Since fiberglass cannot be welded, the corners of fiberglass window frames are created mechanically. This can make them appear less aesthetically pleasing, although this method is sometimes preferred for older homes. In addition, mechanical joints are less durable than welded joints
Comparing Fiberglass with Other Window Materials
Let’s outline the differences between fiberglass and other window frame materials, as they’ll help you see the bigger picture and make the correct decision:
- Vinyl windows are cheaper than fiberglass windows but, on the other hand, have a shorter lifespan because they aren’t as durable. Unlike wood windows, which need regular upkeep, both fiberglass and vinyl window frames require minimal maintenance. Additionally, both vinyl and fiberglass windows are energy-efficient.
- Wood windows are praised for their natural beauty and ability to enhance a home’s aesthetic value. However, they require regular maintenance, including painting and sealing, to prevent damage from moisture and pests. This can be a significant drawback for homeowners seeking low-maintenance options. Fiberglass can mimic the look of wood while providing superior durability without too much maintenance.
- Aluminum windows are extremely durable but lack the energy efficiency of fiberglass options. While suitable for certain climates, aluminum windows do not offer the same level of performance as fiberglass windows.
