A warm welcome to swissFineLine

Passion and innovation are values our family-owned company has espoused from the beginning. Without any doubt, this is one of the reasons our independent company has successfully continued its development from 1886 to today.

That makes us different.

Our philosophy is based on the "Swiss level of perfection" principle, which means that, for us, only the best is good enough. This is reflected in our work and expressed by the unmistakable simplicity and timeless design of our architectural glazing solutions. We would like to appeal to every one of our customers with competent advice, innovative solutions and first-class service.



We believe in quality not quantity. By focusing on tailor-made, single-unit production, we fulfil the individual needs of our customers.



Our drive to innovate sets practically no limits to customer wishes. Innovation is crucial for the long-term success of our company.
