HAMLAR/Germany. Effective August 1, 2025, the Grenzebach Group is consolidating its business operations at the Hamlar site and the Glass Business Unit under unified leadership. Egbert Wenninger, a seasoned expert with over 20 years of experience at Grenzebach and a well-known figure in the glass industry with international experience, will assume responsibility for both areas.
Wenninger brings extensive market knowledge and a deep understanding of the entire Grenzebach portfolio. He sees great potential in both the Hamlar location and the glass business and plans to develop them further, strategically, in collaboration with the global team.
Markus Gruber, the previous head of Business Unit Glass, has left the company as of August 1, 2025, at his own request. The Grenzebach Group thanks him for his dedication and successful collaboration.
As part of this realignment, Florian Nagler—also with Grenzebach for around 20 years and a recognized expert in the glass industry—will now serve as Deputy Head of Business Unit Glass.
