Roll down shutters are commonly referred to as roll up or rolling shutters. When installed correctly, they form a protective curtain with both sides inserted into guide rails. To operate, the shutter is rolled onto an axle covered by durable, aluminum housing. Rolling shutters may be operated manually, motorized independently or in conjunction with a manual override. Motorized shutters work using a switch that can be installed on the wall or by remote control. If you lose power, these shutters can be controlled manually by either accessing the motor or by using the pre-installed manual override that works by operating a gear. All types of hurricane shutters require special techniques that allow emergency personnel such as firefighters or paramedics to enter a home even if the shutters are closed.
