A roller shutter, security shutter, coiling door, roller door or sectional overhead door is a specialized type of door or window shutter consisting of multiple horizontal slats, bars, or web systems interconnected through hinges. The mechanism involves lifting the door to open it and lowering it to close. In the case of larger doors, an automated, motorized system may be employed. This versatile design offers comprehensive protection against various elements, including wind, rain, fire, and theft. When utilized as a shutter in front of windows, it serves as a formidable deterrent against vandalism and thwarting burglary attempts, reinforcing the security of the enclosed space.

Applications

Roller shutters have many applications including doors for vans, garages, kitchens, schools, prisons and warehouses. They are also commonly used as window blinds in some European countries, such as Germany, France and Spain. These shutters serve as insulation in locations prone to harsh weather conditions, safeguarding windows from hail damage and designed to endure strong winds. In specific jurisdictions, property owners might need to obtain a permit or face restrictions on installing specific types of roller shutters on their building exteriors. The cost of these systems can be significant, with the cost being upwards of $25,000-40,000. Plywood boards can also act as a similar deterrent to theft and burglary.
