Glas Trösch has been steadily growing since the time when company founder Johann Friedrich Trösch made a name for himself as a glass specialist in 1905. Not only in Bützberg, the place where it was founded and the site of the company headquarters, but also in more than sixty other locations in Switzerland, Germany, France, Poland, Moldavia and the Ukraine.

From Bützberg to Malans, from Bulle to St. Gallen – Glas Trösch has a presence in more than 20 locations the length and breadth of Switzerland. The individual companies are joined together under the "Processing in Switzerland" umbrella. With pooled strengths and common goals – yet with sufficient independence to respond to your call swiftly and satisfy your wishes in the best possible way.
