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 on the weather, Ultrex fiberglass expands at virtually the same rate as glass. It 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.
An Investment That Can Save You Money on Energy Bills
The low thermal conductivity and superior performance of our windows and patio doors, combined with the selection of energy-efficient glass options can help save money on your energy bills.*
*Savings reflects installing ENERGY STAR® certified products compared to non-certified when replacing single pane windows based on the average savings among homes in modeled cities.
