The sports center is located in the green area between Illnau and Effretikon in Switzerland. It combines many sports and leisure facilities in summer and winter. 

At the entrance and lobby for events, the acoustic curtain STREAMER pro 100 (aw 0.8) is mounted along the window front and works as an efficient acoustic absorber, in the context of the reverberant materials such as concrete and glass.
