The Curtain, when supplied and installed, provides an apparent weighted sound reduction index of (Rw) of at least 40dB(A) when measured on site at the centre of the front row of stalls seating.
The dimensions can go up to 12 meter high, 17 meter wide and a thickness of only 232 mm.
The system arrangement includes and permits convenient and fail‐safe operation.
