6.3   EXTERNAL WALLS

External walls are of concrete/masonry and will not require acoustic upgrading. Alternative construction
details may be suitable but must be submitted to Acoustic Logic for review and approval.

6.4   ACOUSTIC SEALING OF WINDOW FRAMES

Where glazing is required to achieve a nominated acoustic performance the perimeter of the window frame
shall be acoustically sealed into the window opening so there is no leakage of noise between the window
frame and the building opening. The sealing method selected shall take into account and allow for any
movement of the window frame relative to the building opening and so that the acoustic performance is
maintained.
