9. Recommendations
9.1     Road Traffic and Offsite Noise
Acoustic façade treatments are required to minimise noise from road traffic and offsite noise from
the neighbouring commercial premise. The dominant noise source, road traffic, is driving the
recommendation is listed for each noise-affected room.
9.1.1    Glazing
The minimum glazing treatments are presented in Table 13, with the installed glazing system to
comply with the following:

   •    The minimum glass thickness specified shall not be reduced regardless of the Rw
        performance of the glazing system.
   •    If compliance cannot be achieved with the minimum Rw ratings, the glass system shall be
        upgraded until compliance is achieved.
   •    Glazing specified with acoustic seals requires a Q-lon seal or an equivalent product, mohair
        seals are not acceptable.
   •    The glazier shall provide NATA test reports on request to verify compliance with the minimum
        Rw ratings. Generic reports are not acceptable.

9.1.2    Alternative Ventilation
We recommend that all locations nominated in Table 13 have the provision for an alternative
ventilation system similar to air-conditioning or mechanical ventilation to allow windows and doors
to be closed. Refer to National Construction Code (NCC) 2022 requirements and AS1668.2
