NW Clad 740
Slimmest Aluminum Clad Folding Glass Door
- Clip-on cladding technology, solid wood core, and narrow clad frame delivers exceptional energy efficiency
- Intersection of two folding panels is 5 13/16″ (148 mm)
- Floor supported panels capable of heights up to 9′ 10″ (3000 mm)
Slim Design, Beautiful Aesthetics
NW Clad 740 provides the slimmest aluminum clad frame in the folding door industry. With the warmth of a quadruple laminated cross-grained wood frame to the interior and durable aluminum cladding on the exterior, the profile is styled in a crisp, angular design. The slim nature of this system provides an intersection of two folding panels at a mere 5 13/16″ (148 mm). This floor supported system offers an extremely streamlined appearance with minimal exposed hardware, creating a new level of aesthetics.
Fourth Generation Energy-Efficient Clad Folding Glass Door
Designed for energy efficiency and strong weather performance, the best-in-class NW Clad 740 provides exceptional protection from outside elements and delivers comfort and security when closed. As a NanaWall product, the NW Clad 740 has been put through rigorous independent performance testing for air, water, structural, and forced entry.
Broad Product Configurability
These floor supported panels are capable of impressive heights up to 9' 10" (3000 mm). As a custom-built architectural solution, this system is available in inswing or outswing configurations, and open corner designs.
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. With FourFold and SixFold, wider opening sizes are possible.
Durable aluminum extrusions provide cladding over solid wood frames to create a protective skin on the exterior for enhanced weather resistance and low maintenance. NW Clad 740 incorporates rear ventilation and clip attachments between the aluminum and wood that allow the two different materials to expand and contract, without constraint, during temperature fluctuations. This rear ventilation principle allows moisture to dissipate, which is especially needed in environments where temperatures are extremely hot, humid, or cold.
NW Clad 740 is manufactured with sustainably harvested wood options that meet the international standards of PEFC. Market availability of quadruple laminated cross-grained wood may differ by wood species.
These 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.
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 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.
Three Sill Options with High Heel Resistant Feature
NW Clad 740 has three sill options: Performance, Low Profile Saddle Sill, Low Profile Saddle Sill with UniverSILL®. Standard to all sills is removable aluminum high heal resistant sill inserts. These inserts provide ADA compliance for the Low Profile Saddle, and create a very barefoot-friendly transition.

Unique Gothic Arch Roller Design for Frictionless, Smooth Operation
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.
