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 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.
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.
