Are Infinity windows made from vinyl?
No, Infinity from Marvin windows is made of Ultrex® fiberglass, which is eight times stronger than vinyl. A stronger material means you can have narrower frame profiles and larger glass areas, which translates into a better view!
What is Ultrex® fiberglass?
Ultrex® is pultruded fiberglass pioneered by Marvin Windows and Doors.
Are Infinity windows more secure?
Depending on the age or current condition of your existing windows, replacement windows are likely to be more secure. They will have stronger frames, thicker glass, and better locking systems. Energy efficiency and appearance are all great reasons to replace windows, but isn’t the security of your home just as important?

Window Material and Options
The choices you make about materials, style, glazing, and installation could have a big impact on your energy bill. And some features, like how easy they are to take care of, make windows more appealing for other reasons.
Certain window glazes and glass may provide better insulation, light quality, and condensation resistance. For example, windows with low-emissivity (Low-E) coatings often are more energy-efficient than windows without.
Cleaning and Maintenance
Some materials and features, like tilt-in sashes, make windows easier to clean and care for.
If your windows are not installed according to the manufacturer’s instructions, you might not get the savings or comfort you expect. We are Marvin Certified and all of our installers work only for us.
NFRC and Energy Star Labels
Look for the Energy Star and National Fenestration Rating Council’s window labels when you shop. It can help you compare how well a window blocks cold, heat, and outside air; allows light in; and blocks condensation.
