Why Fiberglass Windows Are Not Popular And Are They Worth It?

Fiberglass windows have many benefits. But they are not so popular among average homeowners for many practical reasons.

The labor-intensive manufacturing process that leads to higher cost, limited options, discoloration, higher maintenance, etc. are some of the reasons why fiberglass windows are not popular among homeowners. 

But it takes an in-depth explanation to understand the whole picture. Stay with me for a while.

What Are The Disadvantages of Fiberglass Windows?

Let’s talk about the downsides of this particular window type to understand why it’s not the homeowners’ first choice.

  • Expensive

The higher cost has made it less popular than vinyl windows. Depending on the brand, it can cost you 10% to 30% more than other window types. 

Manufacturing fiberglass windows is a labor-intensive task. So, brands can’t lower the cost. Also, higher shipping cost is a major concern.

For multiple windows replacement, this can add the cost up way higher than the budget for many homeowners.

But don’t forget – when it comes to durability and strength, fiberglass windows are way better than vinyl windows. Besides, they are still less expensive than wood windows. 

  • Limited Options

Fiberglass windows are still a new concept and manufacturers are still refining their process. And not so many manufacturers are producing it like vinyl windows.

So, as a homeowner, you don’t have many options to choose your brand. Even wood windows have many brands.

Apart from limited brands, there are limited color options as well. So, if you want to match the color of your home with the windows, it will be a little bit difficult.

It has a limited customization issue as well. If you need unique shapes and profiles, fiberglass windows may not be your option.

  • Fading Problem

Fiberglass windows are susceptible to UV light. Meaning, when exposed to UV rays, they become chalky. They will fade over time unless they are properly powder-coated. 

This happens a lot to darker-colored fiberglass windows.

Once they are faded, they need to be repainted to maintain the consistency of the appearance. 

One can easily avoid this issue if he/she can ensure the windows are already powder-coated by the manufacturer!

Besides, whereas, you can always repaint fiberglass windows; repainting is not possible for vinyl windows. 

  • Not So Sure About Durability

Fiberglass windows are believed and estimated to be durable than vinyl and other types of windows. 

But no one has experienced that in their life since this is new in the marketplace.

  • Not So Easy To Find

When you compare them with vinyl windows, fiberglass windows are harder to find. Not every store sells them considering the less demand. 

If you need them right away, fiberglass windows may not be the right choice. Because there is a longer lead time for ordering such windows.

  • Professional Installation Required

Due to the required precision, DIY installation is very challenging when it comes to fiberglass windows installation. 

You need to hire a professional for professional installation.
