The history of the KLOSE company begins with its foundation in 1897 by master carpenter Josef Klose. Over the next decades, Richard Klose carried out classic carpentry work in the company. At the end of the 1960s, Günter Klose began manufacturing vinyl windows - a real innovation. With a feeling for the wishes of the customers and skilled craftsmanship, the KLOSE company succeeds in steadily increasing the number of employees over the next few years.

In 1996, the brothers Reinhard and Manfred Klose took over the management of the company and since then, together with a motivated core workforce, have ensured further growth and solid success. Today, our family business presents itself as a successful company in its fourth generation. A total of over 60 employees work in our main factory in Clausthal-Zellerfeld and in our competence centre in Berlin.

Wherever craftsmanship, quality-oriented know-how and innovative solutions are required, we are at your disposal as your contact partner.
