A Quick Comparison Between Vinyl and Fibrex® Windows

When you’re planning a window replacement project for your home, you have a wide range of choices when it comes to materials, including aluminum, wood and even fiberglass. While these are good choices, some homeowners tend to gravitate toward two other material options: vinyl and Fibrex®.

Here’s a quick comparison between the two:


When homeowners are looking for an energy-efficient window, one of the things they look for before making a choice is a window’s insulation properties. Thanks to the materials involved in their design and manufacturing, both vinyl and Fibrex windows can help you save a significant amount on your monthly bills thanks to their superior insulation properties.


Window size is important to some homeowners as it dictates the amount of natural light that can enter a home, which in turn can reduce the homeowners’ reliance on artificial lighting. As the frame material’s strength decides the size of a window, Fibrex is slimmer compared to vinyl, but it can still support the same size glass. Therefore, if you’re looking for a window that gives the best outdoor view, consider picking Fibrex over vinyl for your window replacement project.


While vinyl is touted as one of the strongest materials on the market, it can’t hold a candle compared to Fibrex. This is because when faced with frequent temperature changes, vinyl frames tend to suffer from distortion due to heat exposure, which causes it to expand and contract. In fact, vinyl expands twice as fast as Fibrex, which can tolerate higher temperatures compared to vinyl windows.

Environmental Impact

On the other hand, if you’re looking to reduce your home’s environmental impact, install Fibrex windows instead of vinyl ones. While vinyl frames are made of new materials, Fibrex is partially made of reclaimed wood fibers, reducing the amount of trash that would end up in landfills. This makes Fibrex more sustainable compared to vinyl.
