Campus Witten-Herdecke

Sustainable new university building with a focus on wood as a natural building material.

Until now, glass, steel and stone have dominated the architecture on the campus of Witten/Herdecke University. In the new three-storey extension, the Berlin architects Kaden+Lager are now completing this material collection with the natural building material wood. because the new building with office, administration and seminar rooms, library and café bar is intended not only to be one of the most sustainable university buildings in Germany, but also and above all to create a feel-good atmosphere in the midst of a modern and dialogue-oriented working and learning environment. The flexibly usable interiors create plenty of space for communication, but at the same time numerous retreats are offered for concentrated work. Above all, the interior finishing with LIGNO® acoustic elements make a good contribution here – quietness and a pleasant room climate are guaranteed.

    Various wood species are available for the visible layer. For quality reasons, individual wood species cannot be configured for all profiles; for technical reasons, surface treatments are excluded for some wood species.

    Wood type

    _WTE Silver fir knotless, economy 


    "The visible layer is profiled with joints. The code for profiling indicates in millimetres: Element width, strip width (rounded, from/to if applicable) and joint width (rounded) as well as a letter identification for variants, e.g. with chamfered strip edges or with additional height gradation.  

    Note: Some profiles indirectly cause exclusions for other configuration options."


    _625-18-6 Slat profile


    The face is subjected to a brushing _gb as standard, which produces a stronger or weaker structure depending on the type of wood and makes the surface less sensitive to scratches.  Alternatively, a smooth sanding _gs can be carried out, or on request a bandsaw cut _grimitated.


    _gb Brushed 


    Depending on the type of wood, the optional application of a surface treatment is possible ex works. Individual colour finishes are always sampled for coordination. For elements in individual lengths, colour treatment is limited to max. 5 m length.

    Room acoustics

    If the soffit of the element is to have a good sound-absorbing effect, the penultimate layer is configured as absorber _a50g. Otherwise, this layer is configured as a solid wood layer _a0.
