#PRODUCT# has been added to the watch list!

[Translate to Englisch:] Große Holz/Alu-Hebeschiebetür von Josko in einem lichtdurchfluteten Wohnzimmer

The most beautiful windows and doors for every architectural and interior design style. In order to meet these high standards, we rely on solutions developed in-house and our own manufacturing with high added value. That is why everything that significantly influences the quality and design of our products is in our own hands.

This enables us to coordinate everything from the window itself to insect screens and sun protection.

Die Josko-Scheuringer Gruppe

Our family-run group of companies enables us to cover all the important parts of the value chain for beautiful windows and doors ourselves.

Josko, as a manufacturer of windows and doors, and Eurosun sun protection and Glastech, as manufacturers of insulating glass, are closely linked as sister companies.

All three are majority-owned or wholly owned by the Josko-Scheuringer Group.

The Josko-Scheuringer Group has a total of 1,137 employees. Total turnover amounts to €196.8 million (as of 2025).
