Roller shutter The roller shutter has been established as a privacy shield. It consists of a lamellar profile (e.g., PVC, aluminum, wood or steel), can be single-walled or double-walled and can be equipped with or without light and ventilation slots. In double-walled profiles you have a thermal insulation and an insert that stiffens the lamellas. Nowadays, roller shutters are available in many different colors and can beathe new life into a rather boring facade. There are the following models:
  • top mounted shutters
  • new building shutters
  • front mounted shutters
