SL73 is monumentally -sized, thermally broken aluminum folding panel system designed to provide an opening glass wall or storefront up to 38’ (11.5 m) wide. For many applications, the SL73 provides hurricane protection that meets stringent hurricane code requirements and protects your property. In accordance with Florida Test Protocols TAS 201 (large missile impact), TAS 202 (structural pressure, air, water (higher weather performance only), forced entry), and TAS 203 (cyclic pressure). SL73 is vandal-resistant and bear-resistant. The system is tested for acoustical performance with impact glass, as SL70 has the same profiles. NAFS (North American Fenestration Standard) test results for structural pressure, air, water and forced entry were the same as Dade County Protocol TAS 202.
