The best glass for hurricane-prone areas is impact-resistant laminated glass designed specifically to withstand high winds and flying debris. These specialized glass units consist of two or more glass layers bonded together with a strong polyvinyl butyral (PVB) or ionoplast interlayer that holds fragments in place even when broken. To meet stringent coastal building codes like the Miami-Dade County requirements, impact glass must pass large and small missile tests simulating wind-borne debris. The optimal configuration includes heat-strengthened outer panes rather than fully tempered glass, providing better post-breakage integrity. Glass thickness should range from 9/16″ to 1″ for maximum protection depending on window size and design pressure requirements. Installation in reinforced frames with enhanced anchoring systems completes the hurricane protection system. While typically 15-35% more expensive than standard options, impact-resistant glass eliminates the need for shutters or panels while providing year-round protection, enhanced security, and significant noise reduction benefits.
