Municipal Services Building

France


Ceilings Gerko

The Municipal Services Building is a new office building measuring 1500 m². It is located in the community of Benfeld, in the Alsace region, in the North-East of France. From an architectural point of view, its truncated cone shape is quite atypical. The construction project required the installation of various partitions and ceilings. The key challenge was the application of RIGITONE® ACTIV’AIR® 8-15/20 (random pattern), a completely seamless and monolithic system, to the ceilings and walls of the main conference room, whose interior design follows exactly the shape of the exterior design of the building: a hemicycle inside a truncated cone.

Key Achievements

  • Aesthetics: the craftsmanship and experience of the contractor allowed a fantastic visual outcome (both regarding the precise layout of the pattern and the excellent surface finishing).
  • Sound absorption: the reflection of sound is reduced thanks to the perforated RIGITONE® boards and the sloped walls.
  • Acoustic comfort: beyond sound absorption, the exact design of the room guarantees optimum speech intelligibility (the sound reverberation on walls and ceilings being optimally exploited).

Key Challenges

- An ambitious interior design which involved a complex layout of the RIGITONE® boards, to perfectly align the pattern and perforations (both ceiling & lining).
- The acoustic performance requirements which were addressed both by the design of the room and the extensive application of RIGITONE®.
- The use of RIGITONE® Mix, knowing that the contractor previously had no experience with the application of ready-mixed fillers.
