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.
Impact glass versus shutters
Shutters protect an opening only while they are closed and correctly fastened. Impact units protect it permanently, including the afternoon nobody is home to prepare — which is the scenario that actually costs people their roof.
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.
