A sustainable Rapunzel world 

Ecology not only for products

Following a three-year construction period, a visitor centre in the form of an accessible building sculpture has been created on the works site of Rapunzel Naturkost GmbH: In addition to a large exhibition and event area, it houses a show coffee roasting plant, an organic bakery, a bistro, the organic supermarket, and a yoga and cooking studio. Sustainability can be experienced in many different ways, from the design to the technical concept to the interior finishing with LIGNO® Acoustic light in oak.

    Wood type

    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

    _EIF-i Oak knotless, veneer, impregnated


    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.


    _625-20-4 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.


    _gs Sanded


    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.

    Room acoustics

    _a70g 70 % Absorber

    Fire behaviour

    Few configurations can be configured with a flame-retardant surface. This may result in a modified element structure, greater thickness or the need for measures in the area of the substructure.

    Fire behaviour

    _B-s2-d0 Fire retardant surface
