Certificate description
The Miami Dade Hurricane Code
The Miami-Dade Hurricane Code refers to some of the strictest building codes in the United States, specifically designed to protect buildings from the extreme wind and debris impacts associated with hurricanes. These regulations are enforced in Miami-Dade County, Florida, and are widely recognized as a gold standard for hurricane-resistant construction.
Key Points About the Miami-Dade Hurricane Code:
1. Purpose
To ensure buildings and products (like windows, doors, and roofing) can withstand Category 5 hurricane conditions.
Prevent injury or damage from flying debris during high-wind events.
2. Product Approval – NOA
Products must pass testing to receive a Notice of Acceptance (NOA) from Miami-Dade County.
NOA outlines how the product must be manufactured, installed, and used to meet code requirements.
3. Testing Requirements
Products (like impact windows and doors) must undergo:
Large missile impact testing: Simulates debris impact (e.g., 2x4 lumber shot at 50 feet/second).
Cyclic pressure testing: Mimics repeated wind pressure fluctuations during a hurricane.
4. High-Velocity Hurricane Zone (HVHZ)
Miami-Dade and Broward Counties are designated as HVHZs.
Building products installed in these zones must be Miami-Dade or Florida Product Approved and tested to HVHZ standards.
5. Applications
Impact-resistant windows and doors
