What Glas Trösch does

Glas Trösch is a Swiss family-owned glass company founded in 1905, headquartered in Bützberg, Switzerland, with approximately 6,000 employees operating across 70 locations in 16 countries. The company manufactures and processes a comprehensive portfolio of glass products — including float glass, coated glass, insulating glass units, safety and fire-protection glass, structural glazing systems, interior glass, photovoltaic glass, and design glass — for architectural, industrial, automotive, aviation, and rail customers. It operates dedicated business divisions for float glass manufacturing (Euroglas), technical glass (EuropTec), daylight planning systems (OKALUX), rail glazing, and automotive/aviation glazing, supported by proprietary product brands such as SILVERSTAR, BIRDPROTECT, SWISSDIVIDE, OKAWOOD, OKASOLAR 3D, and Swisslamex Safe.

The group's go-to-market is enterprise B2B field sales directed at architects, construction companies, building developers, and industrial buyers, supplemented by physical showrooms in Munich, Kempten, St. Gallen, and Steffisburg, and digital configurators and calculation programs (SILVERSTAR glaCE, structural calculator, dew point calculator, energy simulator). Revenue is generated almost entirely from one-time product sales of manufactured glass, priced on a project-quote basis rather than disclosed public pricing. The primary end market is architecture and construction (residential, commercial, and industrial buildings), with secondary verticals in solar, rail, automotive/aviation, and technical/display glass.

Commercial highlights include named enterprise references such as CD PROJEKT RED (Warsaw office), ETH Zurich (HIF research hall renovation), Munich Airport, and Swiss municipal utilities, indicating activity across institutional, infrastructure, and commercial project types. Marketing is conducted through owned social channels, technical documentation, showroom visits, and project case studies, and the company maintains internal engineering resources, certification documentation, and specification texts that anchor its role in the architect/specifier workflow.
