SL45
Narrow Framed Folding System Providing Ultimate Versatility

- Up to Unit STC 35 Possible
- Proprietary technology allows folding panels to stack 180-degrees to plane of the opening
- Top-hung system is capable of unlimited widths and many specialty design options
All Aluminum, Narrow Sightlines
The NanaWall SL45 features an all-aluminum design for low maintenance finishes and minimal sightlines that form a picture frame like appearance. All folding and locking hardware is integrated into the profiles for a clean look. There are no surface mounted hinges.
Enhanced Design Options
NanaWall SL45 features all the standard configuration options of a folding glass wall plus so much more. This top-hung system is capable of unlimited widths and many specialty design options that allow you the freedom to operate beyond a typical straight wall design.
Proprietary technology allows folding panels to stack 180-degrees to plane of the opening providing a true breakthrough in the folding door industry. With FoldFlat, the panels fold and then pivot all the way back to stack out of and parallel to the opening.

Burleson Elementary
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.”
