Motorized Rolling Shutters
.
A roller shutter / roller door is a type of door or window shutter consisting of many horizontal slats (or sometimes bars or web systems) hinged together. The door is raised to open it and lowered to close it. On large doors, the action may be motorized. It provides protection against wind and rain. In shutter form, it is used in front of a window and protects the window from vandalism and burglary attempts.
Roller shutters have many applications mainly for industrial entrance spaces, garage and warehouses. In areas that are frequently exposed to inclement weather, roller shutters are used as a method of insulation and can protect against hail damage.
