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 widths up to 36' (see Maximum Size Chart). It is available in various configurations utilizing one to twelve panels. 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 ¼" (6 mm) single tempered or laminated; 15/16" (24 mm) double clear insulating tempered, or insulating Low-E tempered glass) or open. If supplied open, standard glass stops and "dry" glazing gaskets supplied are for a glass thickness of 1/4" (6 mm) for single glazing or 15/16" (24 mm) for double glazing. 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

For each pair of folding panels and on panel(s), if any, provided is two point locking hardware consisting of top and bottom Polyamide capped locking rods operated by a 180 degree turn of a flat handle.

Standard flat handle finishes are dark brown, white, white aluminum or dark gray.

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 rod and turn of key or thumbturn engages deadbolt and locks. The solid brass lever handles are available in an oil rubbed bronze or a satin nickel finish.

2. Deadbolt Lock.

   ADA approved nylon pull handles on both sides with deadbolt(s) operated by lockset. Turn of key or thumb turn operates lock. 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 panels that is attached to the side jamb.

If a unit is inward opening and there is no swing panel, an option to enable a unit to be opened from the outside is to provide on the folding pair to be opened first: Two point locking hardware consisting of top and bottom Polyamide capped locking rods operated by a 180 degree turn of a L shaped nylon handle on the inside and a flat handle on the outside. Lockable with a lockset. Turn of key or thumb turn operates lock. From 13 available colors, the nylon handle color will be the closest match to the flat handle color.
