The aluminum slats in the Minicolor^® series are filled with an environmentally-friendly material, making them sound-deadening; they also provide maximum protection against intrusion (Griesser security concept). Insect screens and a function which prevents the Minicolor^® motor opening when it is frozen are available as an option. Minicolor^® can be integrated seamlessly and discreetly into the building architecture – particularly if the rolling shutters are installed in the header. If space is limited, Minicolor^® can be installed with a suspended cassette. A sliding arm mechanism is also available for optimum room ventilation.
