The document discusses methods to reduce noise transmission through various building systems, including concrete and timber floor/ceiling systems. It highlights the benefits of using acoustic wall panels and systems with high-performance insulated plasterboards to improve sound insulation while maintaining structural integrity. Materials and configurations for effective wall linings, including mineral wool, are also outlined to enhance acoustic performance.

8. High Impact Acoustic Drywall System
Acoustic Stud offers excellent acoustic and
installation benefits when combined with
appropriate Wallboards, and High Performance
Insulated Plasterboards
Acoustic Stud has built in discontinuity which
results in improved sound insulation
designed for frequency bands (250 to 1000 Hz
maintaining structural strength and integrity
this enables slimmer partitions to be
constructed, maximizing floor space but still
satisfying high acoustic requirements
Wall Lining
a range of gypsum plasterboards
and thermal laminates to line
brick, block and concrete walls
Wall Width
200mm (min) between
inner faces of wall
linings

One layer 50mm (min) unfaced mineral wool bats (density 33-60 kg/m3)
Two layers 25mm (min) unfaced mineral wool bats (density 33-60
kg/m3)
two layers 25mm (min) unfaced mineral wool quilt (density min 10
kg/m3)
