Rw (expressed in decibels) is the evaluation index of the acoustic insulation, that is to say an evaluation method that, through a unique number, allows describing the acoustic insulation in a general way, so that it is possible to define the acoustic performances of any partition.

The evaluation index is determined in accordance with the UNI EN ISO 717 standard and is based on the results of the acoustic insulation measurements carried out by third octave or octave bands referred to curtain compositions whose perimeter’s edges adhere perfectly to the side walls, the floor and ceiling.
