WHY MARVIN REPLACEMENT BAY WINDOWS?
Built with Ultrex® fiberglass for timeless design, durability, and low-maintenance performance

Choose from seven exterior color options to boost your curb appeal. Our fade-resistant acrylic finish resists scratches, chalking, fading, chipping, denting and peeling. 48,000 hours of sun can’t fade our finish.
Marvin’s Ultrex® fiberglass finish is verified to the American Architectural Manufacturers Association (AAMA) 624 specification. Achieving AAMA 624 verification means that our Ultrex finish has passed rigorous tests that simulate the harsh conditions a finish can encounter throughout the life of the window or door. Average sunlight exposure per 10 years.
