A roller shutter is a type of door or window covering made of horizontal slats or panels that roll up and down. They are commonly used for security, privacy, and insulation in both residential and commercial buildings. Roller shutters can be operated manually or with an electric motor, making them convenient and easy to use. These shutters are often made from materials like aluminum or steel, providing durability and resistance to weather conditions. In addition to security, they can help reduce noise and improve energy efficiency by insulating against heat and cold. Many people choose roller shutters for their versatility and functionality.
