NanaWall^® SL60: The Thermally Broken Folding Aluminum System

Technical Description SL60

The SL60 is a thermally broken aluminum folding panel system designed to provide an opening glass wall or storefront for openings up to 36' wide; see Maximum Size Chart. It is available in various configurations utilizing one to twelve panels; see elevation drawings. The option exists for swing entry/exit panel(s); note the further panel size constraints with a swing panel not hinged to a side jamb. Units can be either inward-opening or outward-opening; see details in section drawings. The SL 60/o system is the top-hung system and the SL 60/u system is the floor-mounted system.

Frame and Panels

The nominal extruded aluminum frame and panel thickness is 2 3/8" (60 mm), thermally broken with a wide polyamide plastic; see section drawings . Standard finishes are white, dark brown and silver gray powder-coated. Custom finishes can be chosen from a range of over two hundred RAL colors; see Aluminum Finish Options in the General Introduction. It is possible to have different finishes on the interior and exterior surfaces.

Panel stiles, and rails are connected by special cast-alloy, thermally broken corner fittings that incorporate hinge components, with finishes matched to finish of frame and panels. Panels are pre-assembled, and all pins and screws needed to assemble frames are provided.

Besides the more weather resistant raised sill in profile matching finish, various standard aluminum flush sills (shown in section drawings) are available as an option in a clear or dark bronze anodized finish.

Glazing

Units can be supplied either glazed with 15/16" (24 mm) clear insulating tempered or insulating Low-E tempered glass or other high performing safety glass such as heat mirror, acoustical, special tint, etc., or other glass on request. See Glazing in the General Introduction for other glass thickness possible.

Weatherstripping

All weather-stripping (consisting of EPDM or brush seals) is provided for sealing between panels and between panel and frame; see section drawings.

Sliding/Folding Hardware

For sliding and folding of each pair of panels for the SL60/o system, attached to the upper corner of the panel (as indicated on the section drawings) is an upper load-bearing running carriage. Attached as a guide to the lower corner of that panel is a lower-running carriage. The double pair, twin-tandem, upper-running carriage is constructed to insure even distribution of pressure on all four rollers. For the SL60/u system, a floor supported, two-wheeled, lower-running carriage is attached to the lower corner of a panel, and an upper-running carriage is attached to the upper corner of that panel as a guide. Rollers have sealed bearings and are coated with toughened Polyamide to ensure sound-free running and optimal resistance to extreme temperature. Hinges at the corners of each panel are provided to connect panels together and to connect panels to frames.

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 panels), provided is two point locking hardware consisting of top and bottom Polyamide capped locking bolts operated by a 180° turn of a flat handle on the inside only. Flat handle finishes are matched to panel profile finish.

For a unit with a swing panel on the primary swing panel, provided is 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 and solid brass handle set on the primary swing panel, available are matching dummy lever handles on both sides and concealed flush bolts that operate the rods at the top and the bottom.

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 a L-shaped nylon 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.

Standard solid brass lever handle set finishes are white, satin nickel and oil rubbed brass. Standard nylon handle finishes are dark brown, white and gray.
