Experts in glass by tradition
Glas Manufaktur Conzelmann, founded by Silke Conzelmann and Annette Conzelmann, has been manufacturing high-quality Inspection Windows for industrial applications since 2003.
The Conzelmann family can look back on a long tradition of almost 150 years: the Conzelmann glazier's workshop was founded in Tailfingen in 1872. In 1954 it moved to Balingen and developed into a manufacturer of special and insulating glass. In 1978, the grandfather and father of the managing directors started producing individual windows for the environmental test chambers. With founding of "Glasmanufaktur Conzelmann GmbH & Co. KG", this Inspection Windows business segment was taken over.
As a result, the family business can draw on a wealth of experience in the field of Inspection Windows dating back 40 years.
Today, Glasmanufaktur Conzelmann serves well-known customers worldwide.
