What is a roller shutter?
A roller shutter is a roller closure that serves as an additional closure of an opening. It is usually installed from the outside in front of a window or door and, depending on the design, can fulfil various protective properties, such as sound insulation, burglar resistance, thermal insulation, visual protection.
With roller shutters, a distinction is made between the so-called armour, i.e. the part of the roller shutter that can later be lowered in front of the window, and the roller shutter box, in which the roller shutter armour is located when rolled up.
