Alufront's windows and doors have been tested according to US and Australian standard, for thermal rating and Acoustic are above the international standard.
Alufront's products are approved by WERS,NFRC 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 30. Every improvement in Rw value equates to a reduction in decibels of 1.
