Café Gugelhupf at the Hotel Vier jahreszeiten at Schluchsee

Pavilion in a wooden structure

The conversion of the swimming pool and fitness area of the Hotel Vier Jahreszeiten in Schluchsee into a conference café took place in 2018. Thus, the conversion and extension created a light-flooded winter garden also referred to as the Café Gugelhupf, consisting of large panoramic windows and the LIGNO® Acoustic light ceiling elements.

Components used

    Product code: LIGNO® Acoustic light 3S_33_a70g_625-12-4_WTL_gb_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.


    _625-12-4 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.


    _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.


    _b0 Untreated

    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
