SL45
Aluminum Framed Folding Glass Door Designed to Solve Specific Architectural Challenges
- Acoustically tested to meet up to unit STC 34 with sill options designed specifically for interior applications
- Can be configured with segmented curves and 90° - 135° open corners
- Panels can fold 180° and stack parallel to the opening against the wall
Segmented Curve Capabilities
A key feature is the ability to create a segmented curve utilizing the flat glass panels to achieve a curved aesthetic. Segmented curves of 6° - 12° can be created with or without an integrated swing door and 90° - 135° open corner configurations.
Stacks Flat Against the Wall
FoldFlat is a unique configuration of the SL45 that allows the panels to fold 180° and stack flat up against the outside wall, removing the panels from obstructing walkways while also maximizing the circle of sight.
Inward and Outward Stacking, Same Opening
The SL45 includes the ability to have each panel stack open opposite each other within the same plane of the opening (inward and outward) on the same single track.
Innovative design enables the folding panels to stack 180° flat up against the wall for maximum outside space usage and greater circle of sight from the inside.

Acoustical Performance ResultsWhat Our Customers Have to Say
CompTIA Office - Case Study
With "order and light" as the watchwords of the renovation project of the interior of CompTIA, KUBE set about finding ways to create a feeling of openness, while also providing privacy through sound attenuation.
Burleson Elementary - Case Study
To optimize the limited floor space and increase the classroom flexibility at Burleson Elementary, two NanaWall SL45 systems replaced fixed walls to create a new multipurpose FlexSpace.
“This flexibility allows teachers to gain access to shared resources and adapt space for small and large groups as well as project-based learning activities.”

Over 90 standard configurations for straight-forward folding systems.
Standard configurations show the most common way folding glass wall panels align across a straight opening. Panels operate in a continuous line without special conditions such as corner openings, wall pockets, or intersections, making this layout a clear starting point for planning straightforward openings.

FoldFlat 180° panel configurations enable folding glass wall panels to rotate and fold flat against the adjacent wall when open. Panels pivot up to 180 degrees, forming a compact stack that keeps the opening clear and minimizes how far the stacked panels extend from the wall.

FourFold panel sets use four connected folding panels operating along a single track. Panels move and stack to the right, left, or center, allowing flexible positioning based on layout and access needs.

Window-door combination configurations integrate folding windows and folding glass doors within the same opening or wall plane, enabling independent control of daylight, ventilation, and entry. Commonly used for indoor/outdoor kitchens, this layout supports flexible layout design and a clean, consistent visual flow across the space.

Segmented configurations arrange operable glass wall panels across multiple angled or curved segments, allowing the system to follow architectural geometry beyond a straight line. This layout supports faceted walls, gentle curves, and radius designs while maintaining operability and visual continuity across residential and commercial applications.

Cornerless (Open Corner) configurations remove the vertical corner post where two operable glass walls meet at 90°, allowing panels to open in multiple directions and create a fully unobstructed corner opening. This layout enhances visual openness, spatial flow, and flexible indoor-outdoor transitions.
All standard configurations are available in cornerless options.

T-Intersection configurations connect two operable glass walls at a 90° junction, forming a T-shaped layout that enables multi-directional opening and flexible space planning. Common in classrooms, offices, libraries, and conference rooms, this configuration supports adaptable interior spaces.
View More T-Intersection Configurations
Inward / Outward combination configurations allow some panels within the same opening to fold inward while others fold outward, supporting exterior clearance, circulation paths, and furniture placement based on site conditions and design needs.
