Door Collection

Bi-fold doors.

Bi-fold doors change the relationship between a room and the space beyond it. Panels fold and stack cleanly to one side, opening a wall entirely rather than simply offering access through it. The result is something closer to a retractable facade than a door in the conventional sense: full light, full air, and a spatial generosity that makes the rooms on either side feel larger than their footprint. Available across a wide range of configurations, they scale from intimate courtyard openings to full-width exterior walls.

Bellevue bi-fold doors are built to your span in aluminum or aluminum-clad wood, running on precision rollers and secured by European multi-point hardware along every panel. High-performance Low-E glazing, weather-tight seals, and the finish of your choice come as standard, scaling from a courtyard opening to a full exterior wall. Every configuration is quoted as one all-in price and backed by a 10-year product warranty.
