Conference Center

For the Jonzac convention center, Tetrarc has once again called upon Metalobil’s expertise in the field associated with fireproofing techniques from Woodenha Industries in order to design this rattan auditorium in the form of a false acoustic ceiling.

Rattan allows us to create organic, muscular and undulating shapes.

The 790-sqm walls and the ceiling of the auditorium are made of seven conch shells divided into sections according to joint planes. These slices are then cut into unit boxes made of a fire-retardant plywood frame made of poplar, assembled in semi-wood. The whole represents 3500 unique elements on which are fixed 26000 strands of rattan also fireproof.

As the hall is intended for unamplified performances, the acoustics of the boxes are adjusted by applying a layer of plaster to the back, which also contributes to improving the fire behavior of the structure.
