Marvin Elevate® and Essential™ Made with Ultrex®
Trust Marvin Ultrex for Unmatched Performance
Ultrex is 8X Stronger than Vinyl and 3X Stronger than Fibrex®
We test the strength of Ultrex fiberglass so you don’t have to worry about your home. The results speak for themselves. Ultrex resists bending and flexing – that’s confidence Fibrex and vinyl simply can’t match.

A Fade-Resistant Finish
Marvin’s proprietary acrylic finish is 3X thicker than the competition’s, and it was the first in the industry to achieve AAMA 624 verification. No sanding, scraping, or painting required. Our finish resists scratching and denting, and it performs so well that we offer dark colors without fear of UV degradation or fading.

Durability you Can Count On
Constant expansion and contraction can gradually break down windows and doors, causing leaky seals, poor operation, and loss of structural integrity.
Ultrex fiberglass expands at virtually the same rate as glass, so our windows stay tight and true. This makes Marvin windows resistant to leaks, seal failures and, stress cracks that can compromise energy efficiency and long-term performance.
