Venetian Blinds: C System

C System - Frontal Operation Magnet

Frontal operation magnet

Magnetic attraction

The ScreenLine® system designed with the rotational frontal magnetic control, for raising and tilting a Venetian blind integrated within a double-glazed unit, utilizes the force produced by two coupled rotational magnetic devices.  One set of magnets is inserted in the blind head rail within the cavity and the other applied to the external glass surface.

The movement of the blind is achieved through the operation of an external drive system – a continuous cord, an electrical motor or a wand – that rotates the external magnet which in turn drives the internal magnet of opposite polarity with maximum attractive force.  This magnet principle does not compromise the unit seal and guarantees the perfect integrity of the double-glazing unit.

The design of this magnetic system, with external and internal permanent magnetic disks of double polarity on coaxial shafts, enable the system to be used in narrow cavities, essential for design whilst at the same time, improves the power of transmission.

The round pins located in the centre of the disks assure a very powerful strength of mutual attraction, together with an extremely free movement, in order to obtain the maximum gain from the magnetic device. The Neodymium N53H magnets have an unlimited life and are resistant to high temperatures (+120°).

With a simple rational structure and of limited cost with great functionality, the ScreenLine® system with frontal rotational magnetic control can be readily transported for installation in standard double-glazing units with 20 mm, 27 mm and 32 mm cavities.

The system is particularly suited to structural facades, however there are no limits to its application especially where a balance between its excellent technical qualities and refined aesthetic features are required.


Glasses may be heat-treated to enhance their resistance to mechanical and thermal shocks.
