The Next Generation Folding Glass Wall


sl84 Slimmest Aluminum Framed Folding Glass Wall

SL84 — Slimmest Aluminum Framed Folding Glass Wall

The innovative SL84 provides the slimmest aluminum frame of the NanaWall folding glass wall product line. With a frame profile styled in a crisp, angular design, the intersection of two folding panels is a mere 3 7/8" (99 mm). Comprised of a host of proprietary and patented features, this floor supported system offers an extremely streamlined appearance with minimal exposed hardware, creating a new level of aesthetics.

SL84 Aluminum Framed Folding Glass Wall

Next Generation Thermally Efficient Aluminum Framed Folding Glass Wall

SL84 floor supported panels are capable of heights up to 11' 6" (3500 mm). As a custom-built architectural solution, this system is available in inswing or outswing configurations and can accommodate open corner designs.

Put through rigorous performance testing for air, water, structural and forced entry, this next generation system is designed from the ground up and, as a result, is our most thermally efficient aluminum framed folding glass wall.

SL84 Minimal Sightline for a Modern Aesthetic

Minimal Sightline for a Modern Aesthetic

Panel frames are slim and contemporary with a total 3 7/8" (99 mm) junction where the two adjacent vertical stiles meet. The panel profiles offer a crisp, angular design. Top and bottom rails are a minimal 2 5/8" (66 mm), providing slim-line aesthetics. Panel depth is 3 5/16" (84 mm). To coordinate with design programs, horizontal mullions are possible.

SL84 Thermal Break Profile

Patented Multifunctional Thermal Break Profile affords Slim Sightline

The Bionic Turtle® (US Trade Mark. No. 5-598.058) is a patented (Patent No. US10550625B2) polyamide single piece insulbar design that serves many functions. Not only does it provide an outstanding insulating thermal break within the frame profiles for energy efficiency, it also serves as a concealed channel to house the system's locking rods. By being able to combine functions within one element, the Bionic Turtle design allows the slim profile appearance of SL84.

Sl84 door closed


Floating Left/Right Fourfold or Sixfold Panel sets for wider openings and flexible stacking placement

NanaWall SL84 is the only floor supported, thermally broken folding system available that allows for larger opening sizes and flexible space management with the integration of FourFold or SixFold Panel Sets. These panel sets are able to move and stack either to the right or to the left within the same track allowing the panels to be stacked in the most convenient location as needed.

SL84 AntiTilt

Anti-tilt Feature For Dynamic Stacking of Panel Sets

Each floor supported FourFold or SixFold Panel Set is outfitted with a proprietary engineered anti-tilt feature in the head track. This feature assures that the weight of the panels does not cause the panels to lean or tilt to the side when in stacked formation. Panels may stack either to the right or the left side of the opening.

SL84 concealed panel alignment

Concealed Panel Alignment means less exposed panel hinges

The patented (Patent No. US10711510B2) TwinX mechanism aligns panels of over 7' (2150 mm) in height by adding a hidden spring-loaded structural reinforcement feature without the need of an additional exposed hinge in the middle of the system. TwinX interlocks the panels together when the system is closed providing a consistent seal between the panels, specifically engineered to meet higher wind loads. This unique feature provides a clean-lined, sleek and uniform appearance to the system.

SL84 sealing

System width adjustment feature for long-term tight, consistent sealing

System width adjusts with ease. To allow for construction tolerance, a patented (Patent No. US10683688B2) lateral adjustment feature of +/- 3/16" (5 mm) is available at the side jamb. This allows for consistent seal compression within the system and can be adjusted should the need arise. This adjustment feature is located so that it doesn't interfere with the continuous perimeter seal of the frame.

SL84 side jamb

Multipurpose Frame Insert provides Continuous Surface at Side Jamb and Head Track

A black polyamide clip-on multipurpose frame insert conceals all visible frame to structure attachment points and screw heads creating a clean, even appearance. This frame cover piece creates a hollow space to run and guide concealed cabling for the SL84 to connect to a home security system. Lastly, in addition to the extra boost to thermal and acoustical performance, the multipurpose insert provides an extra cavity to attach a third weatherseal for environments that require even more extreme thermal protection.

SL84 Laufwagen


SL84 has three sill options: Hybrid, Low Profile Saddle Sill and Flush. Standard to all sills are removable aluminum high heal resistant sill inserts.These inserts provide ADA compliance for the Low Profile Saddle and Flush sills and create a very barefoot-friendly transition. Furthermore, the inserts offer protection from dirt and debris collecting in the bottom track.

SL84 Bodenschiene

Unique Gothic Arch Roller Provides Frictionless Smooth Operation

The running carriage rolls on two stainless steel wheels with a unique Gothic arch design supported by a double row of ball bearings. With a 2-point contact of each wheel to the floor track, the system glides quietly and smoothly with less friction by providing an equal distribution of weight on the stainless steel track.


SL84 — Floor Supported Technology

Floor supported systems are ideal for applications where load-bearing capability of the header is a concern.

  • Control construction costs. Requires less header load and limits the need for extensive pre-cambering.
  • Improves likelihood of keeping existing header when retrofitting/remodeling.
  • Provides long-term durability and smooth operation.



To accommodate traffic flow, swing panels can be added either to the end of a chain of panels for systems with an odd number of panels folding in one direction or hinged to the side jamb, depending on unit height and configuration. An up to 3' 3" (1000 mm) swing panel hinged to the side jamb is available. Swing doors can be optionally outfitted with higher kickplates for ADA compliance. Panic hardware and top door closers by others are possible.

SL84 Lock Monitoring System

Optional Advanced Lock Monitoring System

For applications requiring state of the art security, an optional lock monitoring system with Reed contacts is available. This optional locking feature can be concealed cable routed through the frames to a home security system. The Reed contact can also be connected to a service/maintenance system that counts the number of opening and closing cycles of the unit advising when it may be time to contact a service technician for routine maintenance.
