NW Aluminum 840 Slimmest Aluminum Framed Folding Glass Wall

NW Aluminum 840—Slimmest Aluminum Framed Folding Glass Wall

The innovative NW Aluminum 840 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). This floor supported system offers an extremely streamlined appearance with minimal exposed hardware, creating a new level of aesthetics.

NW Aluminum 840 Aluminum Framed Folding Glass Wall

Next Generation Thermally Efficient Aluminum Framed Folding Glass Wall

NW Aluminum 840 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 independent performance testing, this next generation system is designed from the ground up and, as a result, is our most thermally efficient aluminum framed folding glass wall.

NW Aluminum 840 | Floor Supported Technology for Long-term Durability

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.

NW Aluminum 840 SWING DOORS

Swing Doors for Traffic Management

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.
