Company

The roots of these traditional manufacturers date back to 1829, when the company was founded as J. R. Schön woodwork and glaziers shop. In 1870 the Glaziers and Glass Trade HAHN was established under the lead of Heinrich Hahn.

Ever since the foundation GLASBAU HAHN has always demonstrated creative solutions in glass. Innovative ideas and successful products have been honored with numerous national and international awards.
