Florida Wind Zone Requirements for Impact Windows in Flagler County
Understanding Wind Zone Requirements

The Florida Building Code sets two relevant areas for glazing: the High Velocity Hurricane Zone, and everywhere else designated as the Wind-Borne Debris Region.
While Flagler County sits outside HVHZ, it remains squarely in WBDR, meaning windows must be protected for debris impact.
Installation and Compliance Guidelines
In practice, that means every glazed opening must be either an impact window or covered by a tested hurricane shutter, with documentation to prove it.
Do not stop at “impact.” You must also match the window’s design pressure to the wind loads taken from the map and your building geometry.
Using ASCE 7, plan on coastal ultimate wind speeds in the mid 150 mph range, decreasing as you move inland, then calculate opening design pressures by size and wall zone mapping.
