Verwaltungsgebäude mit Wandverkleidung LIGNO® Akustik light | Alnatura Arbeitswelt Darmstadt

Wandverkleidung für bessere Akustik im Büro | Alnatura Arbeitswelt Darmstadt

Anyone entering the atrium of the administration building almost feels as if they are in the open air – so much sunlight can enter through the partially glazed wooden roof and the transparent front facades. The new building, which was awarded the German Sustainability Prize 2020, is Germany‘s largest earthen building. In addition to clay and glass, wood is the most important building material: the genuine timber surfaces on the ceilings and the LIGNO® panels around the windows ensure high design aesthetics with the best acoustics.

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
_WTE Silver fir, economy
Profile

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.
Profile
_625-12-4 Slat profile
Structure

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.
Structure
_gb Brushed
Treatment

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.
Treatment

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.
