Hurricane Proof Windows
Hurricane-proof is a search phrase, not a separate glazing class. A South Florida dealer guide says what some sites call hurricane-proof windows are the same product: laminated impact-rated glass in a reinforced frame. FEMA prints that the glass panes may be broken by wind-borne debris; the interlayer is what stays intact. PGT discusses large missile testing, not an unbreakable pane.
