NanaWall^® SL72: The Dade County Hurricane Approved, Folding, Aluminum Framed System

Technical Description SL72

The SL72 is a monumentally-sized, aluminum folding panel system designed to provide an opening glass wall or storefront up to 36' wide; see Maximum Size Chart. It is available in various configurations utilizing one to twelve panels; see elevation drawings. The running post design provides extra stability. An option for swing entry/exit panel(s) is available; however, note the further panel size constraints with a swing panel not hinged to a side jamb. Units can be either inward or outward opening (see the section drawings).

Frame and Panels

The nominal extruded aluminum frame and panel thickness is 2 3/4" (70 mm); see section drawings. Standard finishes available are clear anodized, dark bronze anodized, dark brown powder-coated or white powder-coated. Custom finishes can be chosen from over two hundred RAL colors; see Aluminum Finish Options in the General Introduction.

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

Besides the more weather resistant raised sill, various standard aluminum flush sills (shown in section drawings) are available as an option in a clear or dark bronze anodized finish. (Please note that the flush sill is not approved for Dade County yet).

Glazing

Units can be supplied glazed with either annealed or heat strengthened 7/16" Solutia .09 PVB impact glass or 1 1/8" Solutia .075" Vanceva interlayer insulated impact heat strengthened glass. According to the Dade County approval, heat strengthened glass needs to be used for larger sized inswing panels for higher design windloads; see product approval details.

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 each pair of panels, a patented, floor-supported lower running carriage is attached to the running post profile. An upper running carriage is attached as a guide; see the section drawings. The four roller lower running carriage lies above the water run-off level and 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 resistance to extreme temperature.

Five to seven patented hinges per connection are provided to connect panels and running post profiles together and to connect panels to the frame.

Locking Hardware and Handle Options

For each pair of folding panels and on the swing panel(s), if any, provided is two point locking hardware consisting of top and bottom Polyamide capped locking bolts operated by a 180º turn of a nylon handle. If there is a swing panel, there is the following additional hardware option 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.
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 note that a door closer can only be installed for a swing panel that is attached to the side jamb. (Not Dade County Approved)
3. No Hardware. For panic hardware to be installed by others, the main entry panel can be supplied with no locking hardware. (Not Dade County Approved)

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 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.

From thirteen available colors, nylon handle colors will be closest match to the aluminum profile color.
