Currently, “AI” and Industry 4.0 are the focus of many discussions. At the Cleff company, we are also having a tendency toward more automation, but there are still regions of industry where clearly defined boundaries set the limits. We also encounter these limits, as our daily work is defined by a high level of manual craftsmanship – and this will continue to be the case. Window construction does not only need manual dexterity, but rather the right “feeling“ for materials and construction parts, which can only evolve after many years of working in window construction.
An example: Our staff in assembly bring window frames in the right form with exactly targeted blows with a hammer and can thus align frames with exact tolerances.
Only a few employees have this highly specialised ability after a lot of experience – and thus the above-mentioned “feeling” is only able to develop after many years of working in window construction. An ability, which even the most ingenious robots are not able to perform, even today …
The same also applies to construction: numerous developments are determined by creativity. Many vehicle doors require very individual solutions on account of the special installation situation and the high demands, e.g. on their pressure tightness. In this case, considerable constructive creativity is needed in order to provide acceptable results which can be implemented and keep the cost aspects in mind at the same time.
Individual developments, as they are offered by the Cleff company, always rely on the individual expertise of our staff in construction and assembly – and we are proud to have such talented employees and their individual abilities.

This is not just the epitome of engineering design and technical pioneering spirit, but also the landmark of Wuppertal since 1901: the Wuppertal suspension railway.
Enjoy a breath-taking view and a continuously changing view of the town when sitting in the bright blue carriages – through windows made by Cleff. After all, the entire functional glazing with the windscreen and rear window, side glass panes, flush window top-hung windows and partitions stem from our production, produced for the manufacturer of the “new suspension railway“: the company Vossloh-Kiepe/Stadler.
As a “ traditional Wuppertal manufacturer“ of vehicle glazing, we are naturally proud that our products now accompany the “Schwebebahn” on each journey it makes.
We wish the “Schwebebahn” and all who travel on it a pleasant trip … and enjoy the view!

In Wuppertal, we have also demonstrated a special closeness to Bauhaus and its world famous approach to design. The unusual commitment of the Wuppertal paint manufacturer Herberts, which already brought famous Bauhaus followers, such as Oskar Schlemmer, to Wuppertal is reflected in that both industry and schools of applied arts promised a lot from modern design.

And finally, the Cleff company also stands for the tradition of good design in Wuppertal: we already sponsored a design competition in collaboration with the Bergisch University and Polytechnic in Wuppertal in the 1980’s. Good design is an important component of numerous developments at Cleff today, e.g. the aesthetics of a window or a door have to comply with the overall design requirements of the complete vehicle. Similarly, there is a lot to consider at the human/functional interface: for example, windows and door handles are subject to the high requirements of user-friendly ergonomics and the lay understanding of function – which may even be of life-saving significance.

However, product design can provide even more than this: through creative ideas, it could allow material savings and simplified production processes – which means a reduction in costs.

For this reason, we integrate from the outset experienced designers with many of these developments. They provide „fresh wind", query the basic processes and help to counteract operational blindness under certain circumstances.

100 years of Bauhaus is therefore an anniversary to remember - because even today we are still able to take advantage of the fundamental principles of Bauhaus.

We have been analysing, designing and programming for a long time and now, it is done: Our new web presence is going online! The new version features many alterations and advantages. So, it eases the precise dsicovery of projects for example and it brings our team to the fore. Furthermore, we are now able to picture many references easily. The design studio „Design Scholemann“, located in Gevelsberg, supported us for this project. They will also attend us in all further matters concerning the public image.

It has been a long time since Tuffi & co – and the characteristical orange waggons oft he Schwebebahn (an overhead railway) were as old as they were. Therefore, the municpal utilities of Wuppertal urgently needed some replacement. The sky blue waggons are in fact produced in Valencia, Spain but important components of the elegant design are produced in the hometown of the Schwebebahn: The frameless windows are produced at Carl Wilhelm Cleff. The local journals have reported about this – read more: link
