Alufront's windows and doors have been tested according to US and Australian standard, for thermal rating and Acoustic are above the international standard. 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 Every improvement in Rw value equates to a reduction in decibels of 1.
