Technical Description

General Description

The SL35 is an aluminum folding panel system designed to provide a moving glass wall or storefront for openings as wide as 36'. (See Maximum Size Chart). The system is available in various configurations utilizing one to twelve panels (see elevation drawings.) The option exists for a swing entry/exit panel; note, however, the panel size constraints with a swing panel not hinged to a side jamb. Units can open either inward or outward. See details in section drawings.

Frame and Panels

The nominal frame and panel thickness is 1 3/8" (35 mm) extruded aluminum. (See section drawings.). Standard finishes available are clear anodized, dark bronze anodized, dark brown powder-coated and white powder-coated. Custom finishes can be chosen from a range of over 200 RAL colors listed in the Color Selection section.

Panel stiles and rails, as well as frame corners, are connected by special cast-alloy corner fittings that incorporate hinge components. Finishes on frames, panels, and fittings are matched.

Panels are pre-assembled, and all pins and screws necessary to assemble the frame are provided.

Besides the weather resistant raised sill, various flush sills and low profile sills (shown in section drawings) are available as an option.

Glazing

Units can be supplied either glazed (with 3/16" (5 mm) single tempered or laminated; or 11/16" (18 mm) clear insulating tempered or insulating Low-E tempered glass) or open. If supplied open, standard glass stops and "dry" glazing gaskets are supplied for a thickness of 3/16" (5 mm) for single glass; 11/16" (18 mm) for insulated glass; or 6-8 mm (single glazing). See the Glazing section for additional details.

Weatherstripping

All weather stripping, consisting of APTK, EPDM or brush seals, is provided for sealing between panels and between panels and frames. See section drawings.

Sliding/Folding Hardware

Attached to the upper corner of a panel (see section drawings) is a patented, load-bearing, upper-running carriage for sliding and folding each pair of panels; 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 pressure distribution 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.

Corner connector with hinges at the corners of each panel connect panels to each other and connect panels to the side jamb.
