The Aluminum Clad Wood Framed Folding System

Technical Description WA67

The WA67 is the commercial/residential folding paired-panel wood framed system with exterior clip-on aluminum extrusion 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; 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 grain solid wood and clip-on aluminum extrusion panel thickness is 2 5/8" (66 mm); see various frame profiles in section drawings. The aluminum head jamb of the WA67/o system is clad with a matching wood fascia piece on the inside. Standard woods available are Douglas Fir, Pine, or Meranti. Other woods are also available. Frames and panels are factory-primed, sand sealed or finished from range of finishes; see Wood Finish Options in the General Introduction. Standard finishes for the exterior clip-on aluminum extrusion are clear anodized, dark bronze anodized, dark brown powder-coated or white powder coated. Custom finishes can be chosen from a range of over two hundred RAL colors and other manufacturers’ pre-matched finishes; see Aluminum Finish Options in the General Introduction.

Panels are pre-assembled. All pins and screws to assemble the frame are provided.

The raised sill, a thermally broken aluminum with polyamide plastic, is available in a clear or dark anodized finish. The various aluminum flush sills are available in a clear or dark bronze anodized finish.

Glazing

Units are supplied glazed with 1” (26 mm) double clear insulating safety, or insulating Low-E safety glass, other high performing safety glass such as heat mirror, special tint, etc., or other glass on request.

Weatherstripping

All weather-stripping 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 WA 67/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 WA 67/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 (except for the pair to be opened first in a unit with no swing panel) , provided 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 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 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 brass or satin nickel, flat handles powdercoated dark brown or silver gray, and nylon L-shaped handles in dark brown or gray finish.
