Fields of activity

Glass production: in-house float glass plants assure our independence

Flat glass produced with the float glass process is the basic material for the products of Glas Trösch. In addition to supplying its own glass processing companies, the factories supply a broad, international network of customers. The four float glass plants in Hombourg (F), Haldensleben and Osterweddingen (D) and Ujazd (PL) are run in partnership with other well-known glass processors and may be called the most modern glassworks in the world.

Glass coatings: comfort all year round

The realization of contemporary glass projects requires an environmentally friendly energy saving concept. Glass coatings make an important contribution to environmental protection. Glas Trösch commissioned its first proprietary magnetron coating line in 1988 and offered glass with heat protection for the first time under the name SILVERSTAR. Today, the company provides a wide range of innovative coatings for a wide variety of requirements.

Exterior processing: glass for building engineering and architecture

Generous window fronts and elegantly glazed facades, canopies, parapets, stairs, floors or noise protection walls, safety and fire protection glass: function and design are harmoniously combined in the diverse, versatile glass systems.

Quality for four generations

Entrepreneurship, quality thinking and the willingness to take risks: These pillars stand for the solid foundation on which the family-owned company Glas Trösch stands and is continually being built up. The foundation stone was laid by Johann Friedrich Trösch (1874-1954) in 1905.

The second generation with Rudolf Friedrich Trösch (1907-1992) extended the production program with the first mirrors, sliding glass doors and shelves.

With the third generation under the brothers Heinz Trösch and Erwin Trösch (1938-2013), Glas Trösch developed into a leading family business in Europe and a major employer in the Oberaargau region. Insulating glass is an important new development of this time. Further production plants in Switzerland and Germany are put into operation.

The fourth generation under the current Chairman of the Board of Directors Erich Trösch builds his own float glass plants and thus guarantees the company-independent self-supply with float glass. To this day, the focus is on first-class quality and permanent customer orientation. With this, Glas Trösch wants to be perceived as a leading family business in Europe for the production and processing of flat glass.

Satisfied customers, dedicated employees, continuous innovation, ongoing growth and environmentally conscious production are the key factors of our proven company philosophy - for four generations.
