Office extension K&D

Good room acoustics and sophisticated room design 

In the two-storey extension for the office of the Kommunikation&Design agency, the LIGNO® Acoustic nature:3D acoustic profile, which won the Focus Open 2020 gold award, complements the purist exposed concrete interior architecture - and creates acoustic quality of stay.

Configuration overview

Components used

  • LIGNO® Acoustic light  |   Ceiling cladding 

    Product code: LIGNO® Acoustic light 3S_33_a70g_625-12n25-4:3D_WTL_gh_b0
    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

    _WTL Silver fir knotless, patterned   



    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.


    _625-12n25-4:3D Slat profile "nature"  


    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.


    _gh Planed 


    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.
