Miami-Dade NOA Certified Hurricane Windows
Best Manufacturer for Miami-Dade NOA Certified Hurricane Windows
What is a Miami-Dade NOA?
A Miami-Dade NOA — Notice of Acceptance — is an official approval issued by the Miami-Dade County Product Control Section. It certifies that a specific building product has passed the county’s testing for the High-Velocity Hurricane Zone (HVHZ), the toughest impact standard in the United States. For an impact window, earning an approval means the exact assembly passed:
- Large-missile impact testing — a nine-pound 2×4 fired at the glass at roughly 34 mph, simulating windborne debris.
- Cyclic wind-pressure testing — thousands of pressure cycles that simulate a sustained storm.
An approval is tied to a specific product, configuration, and size range, and it carries an expiration/revision — so it must be checked against the precise series you’re buying, not just the brand name.
Why NOA certification matters (and how to verify one)
In Miami-Dade and Broward counties, a current approval isn’t optional — your permit and inspection depend on it. Installing a window without valid HVHZ approval can fail inspection, void insurance wind-mitigation credits, and leave your home unprotected. To verify an approval before you buy:
- Ask the manufacturer for the approval number (a Miami-Dade NOA or a Florida Product Approval FL#) for the specific window series.
- Search the Miami-Dade County Product Control database, or the Florida Product Approval system, by manufacturer name or number.
- Confirm the approval is current (check the expiration/revision) and covers your window’s size and configuration.
- Match the design pressure (DP) rating to your building’s wind-load requirement.

NOA vs. Florida Product Approval: what’s the difference?
- Florida Product Approval (FL #) — a statewide approval accepted across Florida and valid for High-Velocity Hurricane Zone use.
- Miami-Dade NOA — the county’s own High-Velocity Hurricane Zone approval, accepted in Miami-Dade and Broward.
Both confirm a product passed the Miami-Dade HVHZ impact protocols. Mr Glass windows and doors carry Florida Product Approval; the company also holds Miami-Dade NOAs where applicable.

Frequently asked questions
What is a Miami-Dade NOA?
A Miami-Dade NOA (Notice of Acceptance) is an official approval issued by the Miami-Dade County Product Control Section certifying that a specific building product has passed the county’s High-Velocity Hurricane Zone testing, including large-missile impact and cyclic wind-pressure testing. It is product-specific and has an expiration date.
How do I check if a window has a valid NOA?
Search the Miami-Dade County Product Control online NOA database by manufacturer or NOA number, then confirm the NOA is current (not expired) and that it matches the exact window series, size, and configuration you are buying. A reputable manufacturer will provide the NOA documentation on request.
Which hurricane window manufacturers are Miami-Dade approved?
Manufacturers whose products hold current Miami-Dade NOAs, or Florida Product Approval valid for the HVHZ, meet the requirement. Mr Glass is a South Florida manufacturer that builds HVHZ-compliant impact windows and doors in its own plant and holds Florida Product Approval across its full line, so each unit matches the assembly that was tested and approved.
Is a Miami-Dade NOA the same as Florida Product Approval?
No. Florida Product Approval (an FL number) applies statewide, while a Miami-Dade NOA is the stricter High-Velocity Hurricane Zone approval required in Miami-Dade and Broward counties. A product with a Miami-Dade NOA meets the toughest impact standard in the state.
