Book AppointmentThe Marvin Signature™ Ultimate Bi-Fold Door opens home to authentic indoor/outdoor living, with panels that fold open and closed like an accordion. So when weather and the seasons don’t lend themselves to an actual ‘open door,’ you can still enjoy a wide-open expanse. With this door, you get it all on a single swinging access door allowing for quick and convenient everyday operation.
Come Fall and early Summer, when it’s time to open up the room and let views and fresh air in, extended widths of up to 55 feet make the Ultimate Bi-Fold Door one of the most extensive folding doors in the industry. Sill options allow you to adapt the door to required performance levels based on environmental exposure. Choose the Performance Sill when the door exists directly to the exterior.
- For sheltered exposure, a Low Profile sill may be appropriate.
- For interior applications, select the Floor Channel as a room divider.
