Replacement Folding (Bi-Fold) Doors
Marvin Replacement Bi-Fold Doors, also called folding doors or accordion doors, have panels that are hinged to each other and fold open and closed like an accordion.
WHY MARVIN REPLACEMENT FOLDING (BI-FOLD) DOORS?
Built with Ultrex® fiberglass for timeless design, durability, and low-maintenance performance
Doors panels stack tightly to maximize daylight when the door is open
Top-hung design lets you easily open and close the door
Configurations up to 7 panels and 22-feet wide
Customize your door with bi-parting (opens from the center) or uni-directional (folds completely open to the left or right) operation
Include an optional access panel with a uni-directional bi-fold door to get quick indoor/outdoor access
Available with a pleated fabric screen that slides and folds away when not being used for expansive views; choose from bi-parting or uni-directional operation
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.
