Highest sound insulation

Relaxation and tranquillity within one‘s own four walls are important factors for quality of life. The system excels through excellent sound insulation (Rw = 46dB) – without any additional measures and over the entire frequency range. The window elements are built flush into their frames at the sides and bottom, minimising the area presented to the wind where it could generate noise.

swissFineLine Silence offers acoustic living comfort even in noisy environments. 

A difference of 3 dB already means a doubling of the volume in human perception.
