The idea of increasing the sound absorption of a tile with micro holes came from China. The product of it comes from us. The development was the result of a joint German-Chinese programme led by the Fraunhofer-Institute for Building Physics (Stuttgart)

The success of this ceiling system is the development of metal ceilings that give optimal sound absorption values and simultaneously maintain the impression of a closed, un-perforated ceiling surface due to the almost invisible microscopic size of the holes.
