WUS acquires Adam Herr GmbH – Two strong brands grow together

As of January 1, 2026, Wilhelm Ungeheuer Söhne GmbH (WUS) will acquire Adam Herr GmbH. Two long-established companies with shared values, regional proximity, and a strong culture of reliability are joining forces — creating added value for craftsmen and distributors alike.

Wilhelm Ungeheuer Söhne GmbH
61389 Schmitten, Germany

A partnership built on shared values

With this acquisition, Adam Herr GmbH will be fully integrated into the WUS organization. The proven products are already available today under the “ADAM HERR Line” within the WUS portfolio.

This step is the result of mutual respect and a common understanding of entrepreneurship: long-term reliability, high product quality, and close, trust-based partnerships with customers and suppliers.

A life’s work in good hands

Andreas Herr, fourth-generation owner of Adam Herr GmbH, has decided after careful consideration to pass on his life’s work and enter well-deserved retirement together with his wife.

Christian Diehl, Managing Director of WUS, states:

“We are committed to continuing and further developing the life’s work of Mr. Andreas Herr. The shared values of quality, trust, and cooperation fit perfectly with the philosophy of WUS.”


More than 115 years of entrepreneurial spirit

Founded in 1907 by Adam and Klara Herr in Niederreifenberg, Adam Herr GmbH has stood for innovation and craftsmanship for over 115 years. Key milestones include early electricity generation from hydropower, the introduction of zinc bends in 1912, and the continuous expansion of practical, market-driven products.

With the entry of Andreas Herr in 1986, the company received further technical impulses and developed additional application-oriented solutions — always with a clear focus on quality and durability.


Clear benefits for customers

For customers, the integration offers tangible advantages:

  • An almost complete roof drainage product range from a single source

  • Reliable availability of proven products

  • The combination of decades of experience and renewed innovative strength

  • The ADAM HERR Line remains an independent brand within WUS, now with increased market presence
