Rolldown Aluminum Shutters are the most convenient of all hurricane shutters. Providing maximum protection against storms and flying debris, this type of roll shutter is permanently installed in a box above the opening and lowered into place by hand crank or electric motor. Additionally, you benefit by the shutters’ ability to reduce energy loss and damage to furnishings and carpet by blocking out the heat and sun. They also reduce outside noise while keeping your lanai clean and adding privacy and security.
