Impact glass is not a single product but a rating. Two units that look identical on a showroom floor can carry very different design pressures, and in Delray Beach that difference is what determines whether an opening holds through a Category 3 or fails at the corner anchors.
Installation is most of the performance
A correctly rated window fitted into an unrepaired opening will never reach the number on its sticker. Anchor spacing, shim placement and a properly sealed perimeter are what let the assembly perform to its rating, which is why the crew matters as much as the brand on the frame.
What the permit process expects
Florida requires product approval documentation at permit stage, and inspectors do check anchor patterns against the approved installation instructions. A contractor who cannot produce the NOA for the specific unit is a contractor who will struggle at inspection.
