NW Aluminum 840
Slimmest Aluminum Framed Folding Glass Door for Superior Thermal Performance and Taller Heights
- Our most energy efficient thermally broken system
- Ultraslim panel frame measuring 1 3/4" (45 mm)
- Floor supported panels capable of heights up to 11′ 6″ (3500 mm)
Our Slimmest Aluminum Frame
The slimmest aluminum frame of the NanaWall accordion glass doors 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.
Fourth Generation Thermally Efficient Aluminum Framed Folding Glass Door
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 door.
Broad Product Configurability
Panel sets are able to move and stack either to the right, left, or center within the same track allowing the panels to be stacked in the most convenient location as needed.
NW Aluminum 840 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 can move and stack either to the right, left, or center within the same track allowing the panels to be stacked in the most convenient location as needed.
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 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.
Three Sill Options with High Heel Resistant Feature
NW Aluminum 840 has three sill options: Performance, Low Profile Saddle, Low Profile Saddle with UniverSILL®. Standard to all sills is removable aluminum high heel resistant sill inserts. These inserts provide ADA compliance for the Low Profile Saddle and create a very barefoot-friendly transition. Furthermore, the inserts offer protection from dirt and debris collecting in the bottom track.
Sill Options
Unique Gothic Arch Roller
The running carriage rolls above the water table 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.
