Fenster- & Türenbau Grünbeck

Product worlds of the future with Roto NX

The story of Grünbeck Fenster‑ und Türenbau began in 1940 with the production of timber windows. These days, the company now also works with PVC and aluminium systems. Maximilian Grünbeck leads the family business in the fourth generation.

The switchover to the Roto NX hardware system is an example of the added value gained through the close collaboration with Roto: this conversion took the product range and production processes to the next level. New functions like TiltSafe and larger sash formats could be implemented. At the same time, the benefits for production include fewer components, faster installation, optimised ordering processes and more efficient machine technology.
