Florida Product Approval vs Miami-Dade NOA Windows: What’s the Difference?

The Main Difference Between State And Miami-Dade Approval

Florida Product Approval and Miami-Dade NOA paperwork both show that a window has been evaluated, yet they do not carry the same weight or cover the same territory.

Florida Product Approval is the statewide path, and it usually tells you the product has been tested for structural performance, water intrusion, impact resistance, and design pressure in the configuration that was approved.

A Miami-Dade NOA is a county-level approval issued after a product is reviewed under Miami-Dade's more demanding hurricane standards.
