All fiberglass windows are not created equal!
Marvin pioneered the fiberglass window market 20 years ago. Today, this commitment to innovation and superior quality has established Marvin as the leader in fiberglass technology. Ultrex fiberglass outperforms vinyl/wood composites, vinyl and roll-form aluminum in virtually every measurable category. While other windows might bend, break or crack over time, our windows hold strong without showing age or wear.

Low Maintenance
Ultrex will not warp, corrode, rot, dent or rust to ensure it always looks new. And, the patented acrylic finish does not require scraping, sanding or painting.

Beautiful Appearance
Ultrex is available in a wide variety of colors to match your needs. The patented finish is up to 3 times thicker than traditional finishes to resist fading. The strength of Ultrex windows allows for more visible glass area, resulting in expanded views.

Strong, stable and virtually indestructible
Ultrex is 8 times more rigid than vinyl. In fact, one inch of Ultrex can hold up to 34,000 pounds. Ultrex windows and doors have low thermal expansion, so they will not stick, swell or warp, ensuring they will open and close just like the day you got them. Plus, low thermal expansion provides a stronger seal resistant to air leakage through the window and moisture.

Energy Efficient
Ultrex maintains its performance in all climates and seasons. Vinyl can breakdown and distort in extreme heat while Ultrex remains stable. Ultrex provides unmatched weathertight performance.
