ACOUSTICS TESTED WINDOWS & DOORS

Sound or acoustic performance of a window is measured by the weighted sound reduction index or Rw value. Rw values are determined by measuring the reduction in dB achieved where a window is used to insulate against a sound source.
The Rw value will increase as the acoustic performance of a window improves, so that a window with an Rw value of 40 has a signi cantly improved acoustic performance over a window with an Rw value of 30. Every improvement in Rw value equates to a reduction in decibels of 1.
