SL73 Hurricane
Hurricane Resistant Folding Glass Door
- Florida Product Approved with Impact Glass in High Velocity Hurricane Zone (HVHZ)
- Forced entry rated and dynamic water performance
- Eliminates the need for unsightly hurricane shutters
Completely Impact Rated
Many approved systems are limited to outward opening and are not approved for areas that need protection from water. The NanaWall SL73 offers a complete impact rated system, allowing both inward and outward opening systems to qualify, while also providing protection from water penetration.
Our Toughest Folding System
The NanaWall SL73 is perfect for securing common areas and in areas exposed to heavy rain. Both forced entry rated and passing a more difficult water test, you can rely on the NanaWall SL73 when you need it most.
Reinforced for Mid-Rises
The NanaWall SL73 has achieved design pressure performance making it acceptable for up to mid-rise level exposures.
Many approved systems are limited to outward opening and are not approved for areas that need protection from water. The NanaWall SL73 offers a complete impact rated system, allowing both inward and outward opening systems to qualify, while also providing protection from water penetration.
Reinforced structural posts and impact rated laminated glass provide unparalleled strength. Dual stainless steel elevated running carriages within the reinforced structural posts are unaffected by track debris and lie above the water run-off level.
The NanaWall SL73 features a door panel depth of 70mm utilizing an advanced thermal strut that provides comfort for all climates and excellent sound control.
