Replacement Windows Case Studies: Are Fiberglass Windows Worth the Extra Cost?

Monday, April 16th, 2018 by Michael Gabrian

Challenge

When exploring the standard wood, vinyl, and fiberglass window options, you’re going to see a lot of differences between the materials. Each material has their own strengths and weaknesses.

Marvin Infinity’s fiberglass window frame has a lot of strengths, while one of it’s main drawbacks is the higher cost. So, is it worth it?

The Lifespan

When comparing the Marvin Infinity Fiberglass window to a vinyl window in terms of lifespan, fiberglass usually wins. We see a lot of vinyl windows fail and need replacement within about 20 years, while fiberglass windows can last up to 50 years.

So although the upfront cost of a fiberglass window is a bit higher than wood or vinyl, it can last up to twice as long. You won’t be required to replace them several time while you live in that home, maybe just once or twice. On the other hand, if you’re trying to sell your home, fiberglass windows can help to increase the value of your home.

The Quality

We should also consider the quality of the materials used. It’s a common problem with vinyl and wood windows that they expand and contract in the winter and summer. This leads to cracking and warping which will not only hurt the performance of your window, but it can lead to seal failure, allowing moisture and air to find it’s way inside.

Fiberglass is a stronger material, which contributes to it’s longer lifespan. It withstands that expansion and contraction and is much less likely to crack or warp. This means, with fiberglass windows, less costs down the line in repairs and maintenance on those windows and less possible moisture problems and drafts.

Marvin Infinity’s fiberglass frame also contains more insulative properties and help a bit more with blocking out outside noise levels. This coupled with Marvin Infinity’s insulated gas can help save you tons of money on your heating and cooling costs down the line.

The Designs

One of the big factors when choosing a window, other than price, is whether or not it works with the interior and exterior of your home. You have several earthy tones to choose from along with the everwood interior finish for a classic, yet durable wood look. After playing with divided lites, grilles, and different window pattern options, you can make Marvin Infinity Windows work with any style home, even authentic, traditional looking homes.

With that stronger fiberglass frame, your window can support the weight of more glass with a thinner profile. The difference is actually quite noticeable when switching from vinyl windows to fiberglass. You notice a little bit more light coming through, really opening up the room. Vinyl windows have a bulky, thick profile because they are a weaker material.

Solution

Whether or not fiberglass windows are worth the extra cost is up to you, but going with wood or vinyl would mean that you’re giving up a lot of perks. Your window will be weaker and susceptible to warping and cracking and you’ll have to get them replaced more frequently than fiberglass.
