What Are Hurricane Impact Windows?
Impact-window assemblies are designed and tested for specific impact, pressure, size, glass, frame, hardware, anchorage, and installation criteria. Performance and approval apply only to the exact documented configuration; confirm the current Florida Product Approval or Miami-Dade NOA required for the property and opening.
Key Components
Laminated Glass
Many impact assemblies use laminated glass with an interlayer. Glass make-up and breakage behavior vary by the exact approved configuration.
Reinforced Frames
Frame material, reinforcement, dimensions, design pressure, anchorage, and limits vary by the exact assembly.
Impact-Resistant Hardware
Hinges, locks, fasteners, and anchorage must match the approved configuration and installation instructions.
Pressure Testing
Testing and ratings apply to the exact assembly, dimensions, glass, frame, hardware, and installation represented by the current documents.
Florida Building Code Requirements
Requirements depend on the currently adopted Florida Building Code, local amendments, jurisdiction, risk category, site, opening, design criteria, and permit. Confirm the current requirements with the building official and responsible design professional.
High Velocity Hurricane Zones (HVHZ)
HVHZ provisions apply in Miami-Dade and Broward counties. Confirm the exact project criteria and accepted approval documents:
- Applicable impact and cyclic-pressure criteria for the exact opening and assembly
- Project-specific design pressure, size, glass, frame, hardware, and anchorage
- Current approval or Miami-Dade NOA accepted by the jurisdiction for the quoted configuration
Wind-Borne Debris Regions
Outside the HVHZ, requirements still vary by the current code, mapped criteria, jurisdiction, property, and opening:
- Applicable opening-protection and impact criteria
- Property- and opening-specific design criteria
- Approval documents and installation instructions accepted for the project
