Local building authorities also regulate the installation methods, types of fasteners used, and sealants to ensure that the contractors install the windows correctly and provide maximum protection. Homeowners and contractors must stay informed about these requirements, as they are subject to change with new building code editions. 


The most recent update, implementing the 8th Edition of the Florida Building Code, took effect on January 1, 2024.

How Safe are Hurricane-impact Windows?


Hurricane impact windows offer enhanced safety during severe weather conditions. 


They incorporate a polyvinyl butyral (PVB) interlayer between layers of tempered glass, which helps hold glass fragments together if the window is broken, preventing them from becoming dangerous projectiles during a storm. 


The manufacturers test the windows rigorously to withstand high winds. The best impact hurricane windows can withstand winds up to 140 mph and some even higher, offering protection against Category 5 hurricane winds


The frames are typically made of aluminum or reinforced vinyl, providing additional strength compared to standard window materials. While no window is completely indestructible, hurricane-impact windows significantly increase a home’s safety during hurricanes by reducing the risk of window breakage and the associated dangers.
