Solar shading on the patio

Griesser and weinor have a long history together. In 1991, the Griesser Group acquired a majority stake in weinor, laying the foundations for a strong and globally active partnership.


If you are gone from the house for somewhat longer than usual, this is not a problem when you have external venetian blinds and rolling shutters made by Griesser. This is because we have developed a safety concept that is designed to make any potential intruder sweat.

As far as external venetian blinds go, our products Metalunic, Metalunic Sinus, Grinotex and Grinotex Sinus are equipped with a safety locking device that prevents the curtain from being pushed up to allow an intruder to break into the house.

We’ve even taken it a step further with our rolling shutters. From safety locking devices through to end rails with manual bolts or with standard locks, we offer a big selection of safety options. And, our reinforced slats are packed with a special foam.

Our concept is then rounded off with the automatic control: while you are enjoying your holiday, the blinds and shutters are moving as though there were a ghost in the house. The vacation program moves them with automated random switching, which means that your house always has the appearance of being occupied. If you are leaving the house for just a short time, you can also raise and lower the blinds and shutters with the Centero App at the push of a button on your iPhone or iPad.
