Extra-Tall Top-Hung Thermal Break Bifold Door

This extra-tall aluminum bifold door is designed for wide patio, villa, restaurant, hotel, and commercial openings that need panels up to 4,000mm high.

The top-hung system uses 2.0mm aluminum profiles, Kerssenberg hardware, Low-E argon insulated glass, an optional accordion screen, and multiple folding layouts.


Choose This System When the Opening Is Taller

It keeps the same simple folding operation while allowing wider and taller individual panels.

1 Panels can be 550–950mm wide.
2 Panel height can reach 4,000mm.
3 Panels fold and stack to the side.

Why Choose This Extra-Tall Aluminum Bifold Door?

This is the better choice when the project needs taller panels, a wider panel range, and a larger glass cavity.

It Can Reach 4,000mm High

Choose this system for extra-tall openings where the standard 3,000mm folding door is not enough.

Each Panel Can Be Wider

The listed panel-width range extends to 950mm, giving the opening more glass with fewer panels.

Top-Hung Hardware Keeps It Moving

Kerssenberg top-hung hardware in black or silver carries the panels from the upper track.

It Supports a 37mm IGU

Standard Low-E argon insulated glass uses a 24mm cavity, with a maximum IGU thickness of 37mm.

An Accordion Screen Is Available

Add a retractable screen when the opening needs airflow and insect protection.

Multiple Folding Layouts Are Available

Choose common folding codes or a 90-degree post-free corner after the drawings are reviewed.

Configured for Extra-Tall Aluminum Folding Door Openings

Send the opening size, panel layout, stacking direction, glass, screen requirement, and project ZIP code for review.
