Signs The Door Was Built For Hurricane Loads

Hurricane-rated sliding doors are designed around impact resistance and wind pressure, so the glass, frame, and hardware usually tell a story if you know what to look for.

Glass And Interlayer Clues

A common giveaway is laminated glass. It may crack under impact, but it tends to stay in the frame instead of shattering apart.

That said, laminated glass alone does not automatically make the whole door hurricane rated.
