Special Design of Exterior Blinds

In addition to the basic design, exterior blinds can be made in a special design, which gives them additional added value. These are the Heluz, Facade and Emergency designs.

Blinds into the Heluz Lintel is a special roller and Venetian blind lintel, which replaces the standard lintel and meets all insulating properties. In the lintel, there is a system groove for attaching the blind. Heluz carrying roller blind lintel can be fitted with either manual or electric control. All types of slats can be used for this design.

Facade Exterior Blinds are mounted directly on the facade of the building in front of the window opening. This design is suitable for Cetta 80 and Zetta 90 blinds. The slats are guided in round guide rails, which are provided with a rubber seal for quiet operation of the blinds. Control: lowering, pulling up and tilting the slats only by the motor.

Emergency Safety Blinds are used to immediately pull up the exterior blinds in the event of a sudden danger (fire, flood or other threat to human life) and thus make the escape exit accessible. It can be used with any ISOTRA exterior blind with guide rails. The system is controlled by a spring mechanism, so it is functional even in the event of power cut.
