NanaWall^® WD66: The Standard Wood Framed Folding System

Technical Description WD66

The WD66 is the standard commercial and/or residential folding or paired-panel wood framed system designed to provide an opening glass wall or storefront for widths up to 40'; see Maximum Size Chart . It is available in various configurations utilizing one to twelve panels; see elevation drawings. The option exists for a swing entry/exit panel(s). Units can be either inward-opening or outward-opening; see section drawings.

Frame and Panels

The three-layer, cross grained, solid wood panel frame thickness is 2 5/8" (66 mm); see various frame profiles in section drawings. The aluminum head jamb of the WD66/o system is clad with matching wood fascia pieces on both sides. Standard woods are European Pine, Douglas Fir or Meranti. Other woods are also available. Frames and panels are factory-primed, sand sealed or, for interior applications, finished from range of finishes; see Wood Finish Options in the General introduction. Panels are pre-assembled. All pins and screws to assemble the frame are provided. The raised sill, thermally broken aluminum with 3/4" (18.5 mm) wide polyamide plastic, and various flush sills are available in a clear or dark bronze anodized finish.

Glazing

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

Weatherstripping

All weatherstripping consisting of EPDM or brush seals is provided for sealing between panels and between panels and frames; see section drawings.

Sliding/Folding Hardware

For sliding and folding of each pair of panels, for the WD66/o top hung system, a load-bearing, upper-running carriage and a lower-running guide carriage is attached between the two panels (shown in the section drawings). The double pair, twin-tandem, upper-running carriage is constructed to ensure even distribution of pressure on all four rollers.

For the WD66/u floor mounted system, a floor supported, lower running carriage and an upper running carriage as a guide is attached between the panels. 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 clear or dark bronze anodized hinges per connection are provided to connect panels together and to connect panels to the frame.

Locking Hardware and Handle Options

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

Standard flat handle finishes are dark brown or silver 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 rods 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 a 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 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.

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 180º turn of a nylon L-shaped handle on the inside and a flat handle on the outside. Lockable with a lockset. Turn of key or thumb turn operates lock.

For units with a primary swing panel and a secondary swing panel, there is the following hardware option on the secondary swing panel: Matching dummy lever handles with operation of the concealed two point locking with a single side mounted bolt.
