Benefits of Replacement Windows with Ultrex® Fiberglass

Infinity® from Marvin replacement windows come with Ultrex® that meets all these factors. The result is a strong and durable material with several benefits and features:

Replacement Windows


Ultrex is a compound made from glass cables and compounded resins bonded through pultrusion. This makes the material a lot stronger than vinyl and low-carbon steel. Manufacturers of this material use blades with diamond edges for cutting. This superior strength doesn’t just mean it can withstand strong impact from flying debris. It also means that we can offer replacement windows with narrower frames and a wider glass area. They can lead to better views and more daylighting for your home.


Manufacturers form the Ultrex’s glass cables from silica sand. This results in a reduced demand for new plastic. Furthermore, windows with Ultrex have long service life. This means that you won’t be replacing your windows in a few years, reducing landfill waste.

Reliable performance

Ultrex can resist extreme temperatures with its low thermal expansion rate. It can also keep its shape where other materials would have cracked or warped, resulting in consistent window operation throughout its service life.

Low maintenance

You can choose from a wide variety of molded-in colors for your Ultrex window replacement in Aurora, IL. It doesn’t require sanding, scraping, or painting. The mechanically bonded finish resists scratches and prevents fading due to UV damage. With these features, Ultrex replacement windows are virtually maintenance-free.

Energy efficiency

Ultrex frames feature superior insulation that complements the double- or triple-pane glass options and low-E coatings. This combination helps prevent thermal transfer and keeps heat where you need it: inside during winter and outside in the summer. With energy-efficient windows, your home would need less heating and cooling, resulting in reduced energy costs.
