The High Velocity Hurricane Zone provisions within the Florida Building Code set the engineering floor for every impact window installed in Miami. These provisions require that the window assembly pass both a large missile impact test (a nine-pound two-by-four fired at a specified velocity) and a cyclic pressure test that simulates sustained hurricane wind loading. The product must carry a Miami-Dade NOA (Notice of Acceptance) confirming it has passed these tests, and that NOA number is referenced in the building permit application. An installer who cannot produce the NOA documentation for the product being installed is not meeting code.
Haven Home Remodeling Group specifies only products with current Miami-Dade NOA certification for every Miami installation. The NOA reference is included in the permit package Haven files with the county, and it is verified by the building inspector during the post-installation inspection. This documentation trail is not paperwork for its own sake. It is the mechanism that proves the installed product matches the approved product and that the home’s building envelope meets HVHZ standards.
