A roller shutter is a versatile and durable window covering made of horizontal slats that roll up or down to open or close the window. Typically made from materials like aluminum or steel, roller shutters provide enhanced security, privacy, and insulation. They are ideal for controlling light, blocking out noise, and protecting against weather conditions. Roller shutters are commonly used in both residential and commercial settings, offering a sleek and functional solution to safeguard windows while adding an aesthetic appeal.
