Why Fiberglass is the Best Choice for Your Windows?

Although fiberglass windows are a relatively new concept, they have become more popular with homeowners nationwide. Let’s take a closer look at Fiberglass windows below and highlight their benefits and features.

Durability and Strength

When compared to wood or vinyl, fiberglass is a better option simply because it’s stronger and can handle the outside elements far better than other types of window material. Recent tests have shown that fiberglass can be up to 9 times tougher than traditional windows made of vinyl. Although no window technically provides structural support for your home’s framework, fiberglass does a far better job of providing structural stability within the window frame.


Although initial costs are always important when considering purchasing windows, you’ll also want to think about long-term costs. The good news is that Energy Star approves fiberglass windows because they can reduce heating and cooling costs by up to 20%. This is much higher than wood or vinyl windows that peek out at around 12%. It may not seem like much on your monthly bill. You will, however, see a savings of hundreds of dollars over the course of several years.

Fiberglass Can Provide a Natural Look

Say the word ‘fiberglass’ and most homeowners conjure images of mechanical windows that lack warmth and feel. On the contrary, fiberglass windows can now emulate the look of natural wood or other materials. In fact, you’ll be able to choose from a wide array of styles, textures, and patterns with fiberglass windows. Once installed, you won’t be able to tell the difference between fiberglass and natural wood.

Are Fiberglass Windows Affordable?

On average, you’ll pay between 15-20 percent more for fiberglass windows than you will for wood or vinyl windows. The tradeoff, however, is that they will last far longer. You’ll spend less money in the long run on window replacements or repairs. Fiberglass windows are expected to last up to 40 years. Average warranty duration is 25 years depending on the manufacturer. So, in the end, the money you spend up front will be saved ten-fold down the road.

Overall Glass Area

One of the greatest benefits of fiberglass windows is that they provide more glass space than vinyl or wood windows. Fiberglass is stronger than vinyl; thus, it requires less material around the glass. Fiberglass frames are thin and allow more glass to be shown through the window.
