ULTREX® FIBERGLASS FOR UNMATCHED PERFORMANCE:

Marvin pioneered the use of fiberglass for replacement windows and doors over 20 years ago. We go even further with Ultrex® fiberglass—our proprietary fiberglass solution that offers unsurpassed durability and timeless style.

We created Ultrex® fiberglass to provide a window and door material that you don't have to worry about. Our Ultrex fiberglass is virtually maintenance-free, resists scratches, dings, and dents so it continues to look stunning.
