NW Acoustical 545
Wood Framed Interior Folding Glass Wall for Superior Acoustical Control
- Quadruple Laminated, Cross-grained Wood Frame Delivers Exceptional Acoustical Performance Up to Unit STC 41
- Intersection of Two Folding Panels is 5 11/16″ (144 mm)
- Floor Supported Panels Capable of Heights Up to 9′ 10″ (3000 mm)
NW Acoustical 545—Up to Unit STC 41 Possible
NW Acoustical 545 is the first floor supported, wood framed folding glass wall able to achieve sound control up to an impressive unit STC 41.
This system combines solid, single species wood framing and specialized gasketing with sound-enhanced glass to achieve optimal performance with the range of unit STC from STC 31 up to STC 41—all while allowing maximal transparency and natural daylight to flood interior spaces.
Minimal Sightline Equals Increased Transparency
With an extremely thin wood frame profile, NW Acoustical 545 is specifically engineered for workplace applications and for interior spaces where acoustical privacy and ease of use are of utmost concern.
ADA Compliant Flush Sill for Workplace Design
The Flush sill option is ADA compliant with an aluminum floor track insert that provides high heel protection. This sill can be installed directly over finished flooring to create clean transitions between interior spaces.

This Generation 4 wood framed interior folding system allows for larger opening sizes and flexible space management with the integration of FourFold or SixFold panel sets. These panels are able to move and stack to the right, left, or center within the same track allowing the panels to be stacked in the most convenient location. The system may be either inswing or outswing, and open corner are possible.
Floor supported systems are ideal for applications where load-bearing capability of the header is a concern.
- Provides long-term durability and smooth operation.
- Control construction costs. Requires less header load and limits the need for extensive pre-cambering.
- Improves the likelihood of keeping existing header when retrofitting/remodeling.
To accommodate traffic flow, swing panels up to 3′ 3″ (1000 mm) 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.
Swing panels have been tested and passed over 500,000 cycles and can be optionally outfitted with higher kickplates for ADA compliance. Top door closers by others are possible.
Unique Gothic Arch Roller
NW Acoustical 545 is engineered for ease of use. Hinged panels are intuitive and quick to operate allowing staff to easily open or close the system on demand. The running carriage rolls on a Gothic arch stainless steel wheel 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.
Minimal Surface Mounted Flush Sill for Seamless Integration
Designed specifically for interior applications, the Minimal Surface Mounted Flush sill is ADA compliant and when installed with finished flooring, has only a mere 15/16" (23.5 mm) visible groove. The shallow surface mounted sill allows for easy installation. This sill can be installed on the foundation or sub-floor and finished flooring can butt up to the floor track creating a seamless integration between interior spaces.

What Our Customers Have to Say
Gunster Law Office
This forward-thinking law firm was designed for openness and transparency, yet provide the confidentiality legal clients expect.
CompTIA Office
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.
“We selected NanaWall for two reasons: openness and flexibility. The owners desired privacy for conferences, and openness for gatherings—we achieved both with the use of a folding glass wall from NanaWall.”
— Janet Bloomberg, KUBE Architecture, Architect
To ensure the longevity of our wood systems, we provide triple and quadruple laminated cross-grains to accommodate the wood’s natural expansion and contraction.
