NanaWall^® WD65: Folding or Paired-Panel Wood Framed For Special Applications

The WD65 is the commercial folding/paired-panel wood framed system for special applications designed to provide an opening glass wall or storefront for unlimited widths (see Maximum Size Chart). It is available in various configurations utilizing one to twelve panels or more with unhinged pairs of panels; see elevation drawings. The option exists for a swing entry/exit panel(s); note, however, the further panel size constraints with a swing panel not hinged to a side jamb. Units can be either all inward-opening, all outward-opening, a combination of some panels opening inward and others opening outward, or center pivoted (shown in section drawings).

Frame and Panels

The nominal, three-layer cross grained solid wood frame and panel thickness is 2 5/8" (66 mm); see profiles in section drawings. The aluminum head jamb is clad with matching wood fascia pieces on both sides. Standard woods are Douglas Fir or european Pine. Other woods are also available. Frames and panels are factory-primed, sand sealed or for interior applications finished from a range of finishes (see the Wood and Finish Section). Panels are pre-assembled. On a folding pair of panels hinged to a side jamb, the panel hinged to the side jamb is 2 3/8" (62 mm) narrower in nominal width then other panels. All pins and screws to assemble the frame are provided.

All the available sills can be provided in a clear or dark bronze anodized aluminum finish.

Glazing

Units can be supplied glazed with ; 15/16” (24 mm) clear insulating safety, insulating Low-E safety glass, 1/4” (6 mm) single tempered or laminated, other high performing safety glass such as heat mirror, special tint, etc., or other glass on request. See Glazing section.

Weather-Stripping

Double APTK weather-stripping is provided for vertical sealing between panels and between panels and frames; brush seals with flexible plastic web are provided for all horizontal sealing (see section drawings).

Sliding/Folding Hardware

For sliding and folding of each pair of panels, a patented, load-bearing, upper-running carriage is attached to the upper corner of a panel (shown in the section drawings); attached to the lower corner is a lower-running carriage as a guide. The double pair, twin-tandem, upper-running carriage is constructed to ensure even distribution of pressure on all four rollers. Rollers have sealed bearings and are coated with toughened Polyamide to ensure sound-free running and optimal resistance to extreme temperature.

Two to five patented hinges per connection are provided to connect panels together and to connect panels to the frame.

Locking Hardware

Provided with each pair of folding panels (except for the pair to be opened first in a unit with no swing panel), is two point locking hardware, consisting of top and bottom Polyamide capped locking rods operated by a 180º turn of a flat handle on the inside only.

If there is a swing panel, there are the following additional hardware options on the primary swing panel:

1. Multi-point Locking. Consisting of lever handles on both sides, a Schlage compatible lockset, lockable latch, deadbolt and rods at the top and the bottom. Depression of handles withdraws latch, lifting of handles engages rods and turn of key or thumbturn engages deadbolt and locks. For a unit with a secondary swing panel, available are matching dummy lever handles on both sides and a concealed flush bolt that operates the rods at the top and the bottom.
2. Deadbolt Lock. Consisting of push/pull handles on both sides with deadbolt(s) operated by a lockset. Turn of key or thumb turn operates lock. Available is a lockset option of having key operation on both sides. To keep the panel closed, a door closer should be field installed, but please note that a door closer can only be installed for a swing panel that is attached to the side jamb.
3. No Hardware. For panic hardware to be installed by others, the main entry panel can be supplied with no locking hardware.

For a unit with no swing panel, on the folding pair to be opened first provided is two point locking hardware consisting of top and bottom Polyamide capped locking rods operated by a 180 º turn of an L-shaped handle for an inward opening unit and a flat handle for an outward opening unit on the inside. In both cases, there will be a flat handle on the outside. Lockable with a lockset. Turn of key or thumb turn operates lock. Please note that for an outward opening unit, locking from the inside will need to be with a key that may not meet egress requirements.

For a unit where locking/handles on the inside only is desired,like in window applications, on all swing panels or pair of folding panels to be opened first, provided is two point locking with a flat handle on the inside only.

Handle finish schemes:

Standard – Stainless steel lever, flat, and L-shaped handles in brushed satin or black titanium finish.

Optional – Brass lever handles in oil rubbed or satin nickel, flat handles powdercoated dark brown or silver gray, and nylon L shaped handles in dark brown or gray finish.

Push/pull handles are available in dark brown or gray finish.
