We Use Ultrex® Fiberglass for Unmatched Performance
Compared to other materials, Ultrex fiberglass is the strongest window framing material in the replacement industry. The superior strength of Ultrex® results in windows and doors that protect your home and will continue to easily open and close for years to come.
While other window materials can expand and contract depending upon the weather, Ultrex® Fiberglass expands at virtually the same rate as glass. This makes Marvin Replacement windows and doors resistant to leaks, seal failures and stress cracks that can compromise energy efficiency and long-term performance.
Our proprietary acrylic finish is 3x thicker than the competition. Our finish resists scratching and denting, and performs so well that we offer dark colors without fear of UV degradation or fading. No sanding, scraping or painting required - our windows are virtually maintenance-free.
The low thermal conductivity and superior performance of Marvin Replacement windows and patio doors combined with a selection of energy-efficient glass options can help save money on your energy bills.
