Folding Glass - NW Acoustical 645

Unprecedented Sound Control for Interiors

NW Acoustical 645 - Up to STC 45 Possible

NW Acoustical 645 is the first floor supported folding glass wall able to achieve unprecedented sound control up to an impressive STC 45.

This system combines sleek acoustically separated aluminum framing and specialized gasketing with sound-enhanced glass to achieve optimal performance with the range from STC 32 up to STC 45 - all while allowing maximal transparency and natural daylight to flood interior spaces.

Minimal Sightline Equals Increased Transparency

With an ultra-thin frame profile, NW Acoustical 645 is specifically engineered for educational applications and for interior spaces where acoustical privacy, ease of use, and transparency are of utmost concern. (Formerly known as SL64 Acoustical.)

NW Acoustical 645 is an award-winning product.

Unique Gothic Arch Roller Design for Ease of Operation

NW Acoustical 645 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.

Floor Supported Folding Glass Wall Technology

NW Acoustical 645 is the only floor supported folding opening glass wall to achieve STC 45. With floor supported systems, the main weight of the unit is carried by the lower stainless steel wheel assembly gliding on top of the stainless steel floor track. The top track is used merely as a guide. Floor supported systems are ideal for applications where load-bearing capability of the header is a concern.

ADA Compliant Flush Sill for School 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 creating clean transitions between interior spaces.

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 seamless integration between interior spaces.

Left/Right FourFold and SixFold Panel Sets for Larger Openings and Flexible Stacking

This 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 and T-intersection configurations are possible.

Swing Doors for Traffic Management

To accommodate traffic flow, NW Acoustical 645 configuration options allow for an up to 3′ 3″ (1000 mm) swing door at the side jamb at one end or both. For requirements of STC 42 or less, swing doors can be added to an odd number of panels hinged to the jamb. Optional higher kickplates, panic hardware, and top door closers are available.
