Built for a Beautiful and Resilient Coast

Put to the (Impact) Test

Systems are independently tested for impact-resistance. 

Florida Products Approved in HVHZ

Buildings in High Velocity Hurricane Zones (HVHZ) require impact-rated systems. Miami-Dade and Broward County are two HVHZ zones, but others exist along the Florida and Atlantic coast.

Florida Products Approved Not in HVHZ

To be used in the state of Florida, a building envelope product needs to be Florida Approved. Systems need to test and pass air infiltration, water penetration, and structural load tests.

Impact-Rated for Hurricane Prone Areas

The SL73 has been tested outside the lab—in real hurricanes. Customer affected by Superstorm Sandy tell stories of the sense of security SL73 brought. Some even told us they watched the storm from behind their NanaWall system.

Systems are independently tested for impact-resistance. Impact rated systems can be approved by the state of Florida. The impact test is intense—launching a 9-pound 2x4 lumber missile into different spots of a system at 50 feet per second.

Tequesta Residence

The indoor /outdoor environment was exactly what the client and architects envisioned for the living area and guest bedrooms and the top-hung, hurricane approved systems allowed for a continuous flooring material both inside and out.

See Case Study

“Using the NanaWall operable glass walls presented an opening to bring in the pool deck and an exterior view without any obstructions. I am very satisfied with the outcome.”
