NanaWall Generation 4 Folding Glass Walls

Best of 2022

NanaWall Generation 4 Folding Glass Walls are comprised of eight different systems based on a common platform of features offered in three different material choices—aluminum, wood, and clad.

This provides architects with a singular platform with similar aesthetics, features, and performance capabilities that’s highly configurable to their designs and project types.

The result is the slimmest, most energy efficient bi-fold door available. Panels are capable of heights up to 11’ 6”. A newly designed Gothic Arch roller system borrows design ideas from bullet trains with only the sides of the roller touching the track. This allows for extremely smooth and easy operation regardless of panel size or weight. Panels can move in stacks of 4 or 6, unattached to the side jamb and with the ability to stack to either side of the opening—enabling unlimited widths—something never achieved in a bi-fold door.



First and only bi-fold door that has no opening width limitations.

Unique floating panel sets can stack either to the left or right.

Only ADA-compliant sill with a water rating and a high heel resistant feature.

Patented multifunctional thermal break design.

Patented TwinX design and consistent seal between the panels meets higher wind loads.

Patent pending adjustment feature adjusts width for construction tolerance.

NanaWall redefined the category of opening glass walls. By combining precision engineering and hundreds of options across more than 25 unique systems, we offer design possibilities beyond the conventional for almost any space.
