Much more than only glass and frames …

Since 1935, we at Carl Wilhelm Cleff as system supplier of the
international automotive industry, have been producing and developing vehicle windows and doors as well as spare parts – quickly,
individually and highly professional.

But what do we mean saying „Much more than only glass and frames“?
We willingly comment on this in personal talks.
We are looking forward to getting in touch with you.

Having international references, the company Carl Wilhelm Cleff in Wuppertal/Germany is one of the leading producers of vehicle windows and vehicle doors. Furthermore, Cleff is a system supplier for spare parts, as for example rubber elements, rubber seals, handles and glass including accessories. As a partner of the international automotive industry, Cleff delivers door and window solutions for railway vehicles as waggons, locomotives as well as nostalgia trains. Furthermore, fully integrated caravans, coaches, intercity busses, urban busses and small busses are representing another target group of Carl Wilhelm Cleff. Our vehicle windows and doors can also be found in specialty vehicles as emergency vehicles, fire engines, PistenBullys and military vehicles. Construction machines and agricultural machines, tractors, vessels as ferry boats, inland water vessels and yachts are equipped with windows and doors produced by Cleff. Being a certified supplier, we possess our own engineering department, an extensive in-house production depth as well as all necessary certificates.

Our development skills which are on a very high level as well as a constantly optimized production process are distinguishing the company Cleff as a system supplier. Besides, we were able to introduce our extensive know-how into the cooperation with our subsidiary company Westberga. During the long-term cooperation, many nostrums as well as many innovative and individual windows have been developed. In addition to numerous in-house developments and innovative products as for example our Flush Window - the flush vehicle window solution - you can expect from us an intense advice in any aspect of the topics “glass, frames and functions”. You can also expect proactive actions and a production on schedule. Our customers benefit from the advantages of a medium-sized corporate structure: Flexibility and flat hierarchies.
