NanaWall® SL73 - Aluminum Framed Hurricane Approved Folding System

For precise, non-parametric 'static' Revit and IFC models, please check the 3D configurator under 'Links - Tendering Information'.

The SL73 is a monumentally-sized, thermally broken aluminum folding panel system designed to provide an opening glass wall or storefront up to 38' (11.5 mm) wide. 

It is available in various configurations utilizing one to twelve panels or more. The running astragal design provides extra stability. An option for swing entry/exit panel(s) is available; note however the further panel size constraints with a swing panel hinged from a pair(s) of folding panels. Units can be either inward or outward opening. SL73 for all panel sizes and configurations is Florida statewide approved with Product Approval number FL20107.This applies for all stacking configurations. With panel sizes of 3' x 8', SL73 inswing with higher weather performance sill achieved a DP rating of +70 psf / -100 psf, SL73 inswing with the higher weather performance sill achieved a DP rating of +70 psf / -100 psf, SL73 outswing with higher weather performance and SL73 inswing/outswing with saddle sill achieved DP rating of +/- 70 psf.

Units were also tested per AAMA 506, "Voluntary Specifications for Hurricane Impact and Cycling Testing of Fenestration Products" and ASTM E1886 and ASTM E1996 with missile impacts corresponding to Missile Level D and Wind Zone 4.
