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.
What to check before you buy
Ask for the Florida Product Approval or Miami-Dade NOA number for the exact unit being quoted, not the product line. Confirm the design pressure rating suits your elevation, and check the quote includes the buck, fasteners and inspection — that is where cheap quotes hide their gap.
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.
