Folding Doors | Exterior Folding Doors

A distinctive aspect of Bieber’s Capability is without doubt our remarkable flexibility which permits creative solutions for the most demanding designers and architects with exterior folding doors.

The bi-fold door perfectly demonstrates the stable and durable nature of Bieber Architectural Windows’s products. Aluminum is used as the base material and wood as the cladding, creating a high degree of rigidity in one element, in which everything fits perfectly together.

As the panels open, the folded doors don’t take much space.

In a rainy day, most raindrops are blocked by the terrace on top of the door making it hard to land near the door. If you open the door after a rain shower, the water from the outside automatically drains, leaving everything dry inside.

Bieber Folding Doors allows large opening clearance with ease of opening. The Bieber folding doors is most frequently used to open a complete wall, creating a larger opening space with an attractive door arrangement.

Available in multiple configurations inward or outward with an active panel as a regular door, Bieber’s folding doors is the perfect fit for your large opening design in all wood series or aluminum clad or bronze clad series.

The system is constructed using a frame in which moveable sashes/openers are placed in such a way that it is possible to fold up the sashes to the left or right.

These sashes are supported and hinged to each other and the fold is supported at the base by a roller mechanism which slides along the sill profile.

Our Folding doors hardware makes the handling of Folding doors for large openings up to a frame width with simplicity and comfort.
