Since more than 40 years the JET-Group develops, produces and distributes light domes and continuous rooflights. During this time the company, its number of employees and its know-how have grown constantly. In the meantime the JET-Group employs 650 people at the headquarters in Hüllhorst, in Kirchzarten, Nuremberg, Voerde and Berlin, as well as at the foreign locations in Poland, England, Denmark, Switzerland and the Netherlands.

In Germany and the Netherlands the JET-Group belongs to the nationwide market leaders, but also in the other European markets the name JET grows continuously. Especially in the East European markets come up more and more representative industrial and commercial buildings with a high demand of daylight solutions.

Since more than 40 years we invest in people and technology – at our location in East Westphalia, nationwide and beyond that.
