The region around Ilmenau is considered to be the birthplace of technical glass. It was here that the first German liquid thermometer was produced, the first light bulb in Germany, the first vacuum jug for a thermos flask and the first X-ray tube. Otto Schott also worked here on the development of heat-resistant glass.

Today, using a patented process, we produce
Liaver foam glass granulate and the Reapor acoustical panel at Ilmenau, Germany.
