Fiberglass Windows Versus Vinyl Windows -- A Side-by-side Comparison

When it comes time to replace your windows, one of the first questions many people ask is this: "What type of windows should I get?"

In this article, we'd like to look at two of the most popular options: Fiberglass and Vinyl windows.

Strength of the windows:

When it comes to strength of the windows, fiberglass has vinyl beat, hands down – in fact, it's been proven to be at least eight times stronger than vinyl.

So what does that mean for your windows? Well, common vinyl issues like warping and seal failure are much more rare with fiberglass because of its strength.

In fact, fiberglass is such a trusted (but lightweight) compound that it's used in marine bridges, underground gas tanks, and sports cars – which means your windows are in good hands!

Longevity of windows:

Many buyers of new windows aren't looking primarily at price. Longevity is also a very important consideration. Experts agree that fiberglass is the longer lasting of the two options, so if you're looking for your upgraded windows to be around for the "long haul", then fiberglass would be the way to go.

Green considerations:

To many modern consumers, how "green" one option is over another is a big consideration. Where possible, they'd like to have environmental impact as part of their decision-making process.

When viewed from a green perspective, fiberglass is definitely the stronger option. Fiberglass's core component is sand, which is (of course!) found abundantly throughout the planet.

Ultrex fiberglass uses 39% less energy to produce than vinyl. Vinyl also requires a great number of toxic chemicals when it's being produced, which has caused it to have strong production limitations in some states.

In terms of keeping your home energy costs down, both vinyl and fiberglass windows are built to be energy efficient, so either are generally an improvement from what you're replacing. On the other hand, once the vinyl windows begin to warp, there is more leakage from the outside elements, which means higher energy costs.

Aesthetics:

Aesthetically, fiberglass is definitely the winner. Firstly, you're able to paint fiberglass (something you can't do with vinyl), so it fits in no matter what the overall look of a room is. As an example, a window and door company can have it set up where windows can be ordered in five different exterior colors, wood or white interior, and five hardware finishes – so there's lots of flexibility!

Another consideration is how much material needs to be used when manufacturing the windows. Fiberglass needs less protection against warping than vinyl, so you're able to have thin, beautiful windows that are very energy efficient – something that can't be said of vinyl, which requires very thick and visually obtrusive frames and sashes.

Price:

In terms of pricing, vinyl windows are priced all over the map; from $400 per unit up to $2000 per unit. Fiberglass windows vary as well but generally are a little more than the cheap vinyl windows and a lot less than the expensive ones. When making your final choice, you must consider all factors – strength, longevity, aesthetics, and green concerns. When weighed with this in mind, fiberglass emerges as the best "bang for your buck". Your windows will last longer. You'll have fewer problems with them in the future. They'll look better and allow you more window space across your home.

Conclusion:

In conclusion, we'd recommend that you seriously look at fiberglass windows for your next purchase.
