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.
