Is the purpose of Hurricane Shutters to protect the glass from breaking?


The most common question regarding Hurricane Shutters; Is the purpose of Hurricane Shutters to protect the glass from breaking? Answers may vary depending on which expert you talk to. The fact is, the primary purpose of a shutter system is to stop the force of hurricane strong winds and debris from destroying the interior of a house or damaging its windows and doors. Shutters provide protection from high winds and flying debris both of which can cause extensive damage. In the worst-case scenario, a broken window will allow your property to become pressurized causing a total loss, even the loss of life.
After being devastated by hurricane Andrew in 1992 Miami-Dade County became the leader in developing some of the most stringent hurricane codes. In Florida, Hurricane Shutters are regulated under the Florida Building Code (FBC). The FBC is divided into two parts; the High Velocity Hurricane Zone (HVHZ) and the non-High Velocity Hurricane Zone (non-HVHZ). Miami-Dade County and Broward County comprise the HVHZ while the remainder of the state falls into the non-HVHZ.
The primary difference between the two codes is that in the HVHZ, the glass can not be broken while the shutter system is at maximum deflection from the impact of flying debris or from extreme loads/pressure from hurricane force winds. Note, the glass may crack but the assembly will not fail or allow winds to penetrate the building. In the non-HVHZ, the glass can be broken but the shutter system must maintain its integrity, not allowing flying debris to enter the structure or allow the structure to rapidly pressurize.
Hurricane shutters are tested to the highest standards by conducting large missile impact test and cyclic wind pressure loading. In short, the testing of hurricane shutter systems is done first by performing a battery of impact tests by shooting a large missile, between 7-9lbs , 2-by-4 in length from a specially designed cannon at 50 feet per second which is equivalent to the 2-by-4 traveling at 34 miles per hour, simulating flying debris during a hurricane. After being impacted the shutter system is then tested by performing a series of cycle tests which is done by applying pressure to the shutter system in 3 second gusts simulating the effects of high winds during a hurricane and the effects to the shutter system, including the fasteners used to mount the system to a specific substrate (wood, concrete, concrete blocks or steel framing).
