NW Reinforced 847
Slim Aluminum Framed Folding Glass Door for Mid to High-Rise Buildings at Taller Heights
- Thermally broken system engineered to meet higher windload requirements of taller buildings
- DP of +/- 85 psf and CW55 rating
- Floor supported panels capable of heights up to 11′ 6″ (3500 mm)
Reinforced for Midrise and High-Rise Buildings
NW Reinforced 847 has been designed specifically for taller buildings where higher windload requirements and limits to deflection are needed. This system is certified and performance-rated to CW55.
Folding Glass Door for Vertical Living
For openings onto balconies, terraces, and rooftops, this reinforced accordion glass door opens wide to 90% or more and is not restricted as with a traditional slider.
Performance-Driven Architectural Solution for Demanding Environments
Designed for energy efficiency and strong weather performance, this thermally broken system provides exceptional protection from outside elements and delivers comfort and security when closed.
NW Reinforced 847 is the only floor supported, thermally broken folding system available that allows for larger opening sizes and flexible space management with the integration of one FourFold or SixFold Panel Set. 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 the 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 the existing header when retrofitting/remodeling.
To accommodate easy access, 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. Tested to 500,000 opening and closing cycles, 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 Reinforced 847 has three sill options: Performance, Low Profile Saddle Sill, Low Profile Saddle Sill with UniverSILL®. Standard to all sills is removable aluminum high heel resistant sill inserts. These inserts provide ADA compliance for the Low Profile Saddle sills 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.
