Fenster-Striegel GmbH

Our owner-managed, medium-sized company is located in Bierstetten, a village between Bad Saulgau and Bad Schussenried in the district of Sigmaringen.

The decision for our products is the decision for quality and reliability. Due to these demands we make on ourselves, as well as quick decision-making processes and high flexibility, we have succeeded in gaining a steadily growing number of customers. In the meantime, we produce windows and doors for private customers, resellers, carpenters, property developers and public clients with 50 employees and state-of-the-art machinery. Our product range includes plastic windows, wooden windows, wooden-aluminium windows and doors.

A special highlight is the passive house window ULTRAPUR S, which we developed ourselves and which is certified by the Passive House Institute Dr. Feist. This product, which sets standards, is marketed in Germany, Switzerland and Austria. All these attributes as well as motivated and qualified employees have contributed to the fact that today we are a leading window construction company in the region.
