The BiFold Door allows multiple panels to fold away for a clear, unobstructed opening and easy access to the exterior. When closed, wide open expanses of glass elegantly frame the outdoors. In the closed position, the sash hugs tightly to the frame, where weather-stripping inhibits air infiltration and promotes energy efficiency. Hartman can construct a door with unlimited panels, giving you the flexibility to realize your architectural vision.


The BiFold Door features a multi-point locking system that functions via single handle, providing easy operation, superb air sealing, and the utmost protection. This door is part of our European Series, meaning that there is an elegant overlap between the sash and the jamb. Our advanced manufacturing technology ensures the highest precision of parts, combining old world craftsmanship with new world technology.
