The name of this unique all-metal external venetian blind system says it all. So it’s no surprise that Metalunic^® can often be seen in use. This system really does give you everything your heart desires when it comes to solar shading and weather protection. The mechanically relevant components like the steel drive chains are housed in the guide profile and are therefore protected from the wind and weather. And in the unlikely event that something should happen, the slats can easily be replaced individually. The external venetian blinds can be adjusted to any angle, either automatically or manually, at any height. The Griesser security concept is burglar-deterrent as it features an integrated safety locking device. The safety sensing edge prevents the external venetian blind being damaged when encountering obstacles. Metalunic^® does not have any connecting belts or lifting belts between the slats and is therefore extremely easy to clean.
