What determines an assembly's hurricane rating?
A hurricane-rated assembly's overall rating equals the lowest-rated component in the assembly. If a door is rated for a higher design pressure than its frame or hardware, the assembly's rating defaults to the weakest component. Every component must meet or exceed the required design pressure for the opening.
What are FL21194 and FL46851?
These are Florida product approval numbers (NOA numbers) for specific hurricane-rated door assembly configurations. FL21194 and FL46851 designate tested and approved assemblies that meet Miami-Dade County and Florida Building Code requirements for impact-rated openings.
What TAS standards apply to hurricane-rated doors?
TAS 201 covers impact resistance testing (large and small missile), TAS 202 covers uniform static air pressure, and TAS 203 covers cyclic pressure loading. Assemblies must pass all applicable TAS tests to receive Florida product approval for hurricane zones.
Can I mix components from different hurricane-rated assemblies?
No. Hurricane-rated assemblies are tested and approved as complete systems. The door, frame, hardware, and anchorage must all be part of the same tested configuration. Substituting components from a different approved assembly creates an untested combination that does not carry product approval.
Do hurricane-rated assemblies also need to be fire-rated?
In some openings, yes. Where building codes require both hurricane resistance and fire ratings, the assembly must carry both certifications. These dual-rated assemblies are available in 20-minute, 45-minute, 60-minute, 90-minute, and 180-minute fire ratings with hurricane impact resistance. Component selection is more restrictive for dual-rated openings.
