The exact position, size and depth in the wall relief were defined for each individual amoeba with the help of specially developed acoustic software. In order not to have to write a separate CNC program for each of the 3,670 plates despite the high demands on acoustics, to increase efficiency, Knauf Design proposed reducing the programmes to 169 spirals without influencing the acoustics.
Nevertheless, absolute precision work followed: each individual panel was initially given its individual relief by means of computer-controlled milling. For a truly jointless relief over the entire wall surface, however, the individual panels had to be cut to a perfect fit.
In close coordination with the general contractor, each batch was individually packaged, numbered and delivered "just in time" according to the construction progress.
No compromisses in quality.
The coated gypsum fibre board was used as the material. They are ideal for individual machining with CNC milling and can then be surface-sealed with clear lacquer. They were tested for their climatic suitability over several weeks in the climatic chamber of the central Knauf research and development in Iphofen. Verification passed, calculations confirmed.
Result: Zero tolerance in accuracy, 100 percent satisfaction.
