Why Ultrex

3x
stronger

Built unlike any other

Made with 100% fiberglass strands, our proprietary Ultrex material is 3x stronger than Fibrex® and 8x stronger than vinyl.

Fibrex® is a registered trademark of Andersen Corporation.

Outlasts 48K UV hrs

Smooth, lasting finish

Low-maintenance acrylic finish is 3x thicker than all other options, creating a polished look that resists scratching, denting, and fading even after 48,000 hours of sunlight.

17 tons per inch

Extraordinary strength, extraordinary views

Every square inch of Ultrex supports up to 17 U.S. tons, allowing us to expand your views with slimmer profiles.

87% less expansion

Uncompromising climate comfort

Low thermal conductivity paired with specialized glass and a fit that stays true means fewer leaks and improved energy efficiency.

We took an entire wall out in our living room and replaced it with a 16-foot patio door opening out to our deck. We decided to go with Infinity by Marvin because we wanted a fiberglass window in a black exterior and liked the overall look and thin frames."

Jon H.

Ohio Homeowner

Custom, down to the details

Built to your exact specifications, you can mix and match your chosen window shapes with details like profile, grille and divided lite patterns, and elegant hardware. Available in a multitude of finishes, including proprietary EverWood® interior finish, Infinity fiberglass windows are 100% paintable under our warranty.
