Local council had imposed strict mandatory acoustic regulations as part of the renovation which included both a sound absorbing requirement as well as a high transmission loss. Additionally, the acoustic wall required complex installation in and around old and new storm water pipes and pits. Finally, the noise mitigation solution located near the entry and exit stairs of the customer driven premise located along Sydney’s busy Cumberland Highway, had to be aesthetically welcoming.
The solution offered by Modular Wall Systems™ included a custom-designed GuardianWall™ system measuring 4.5m – 5.3m tall and 47m long that incorporated our AcoustiSorb Plus™ panels. Due to the RW rating required, MWS proposed a modified version of our standard AcoustiSorb sound absorbing panel. This panel was designed, tested and acoustically rated specifically for this project.
These panels have a perforated face to absorb sound waves within its core material, resulting in an NRC rating > 0.9. A 9mm compressed fibre cement rear skin then provides a smooth and tough architectural finish on the outside. The density of the compressed fibre cement increased the STC (sound transmission rating) greater than 40 Rw and in turn complied with council requirements.
Working harmoniously with Merlot Constructions, Modular Wall Systems™ installed the required walls in several carefully planned and calculated site visits. This precise planning meant the construction of the wall was able to occur without hitch or additional contractors.
Base plates and large pad footings were used where post embedment depth could not be achieved overcoming challenges from the old and new storm water pipes and pits. The pre-finished internal panel skins meant there was no requirement for painting on the inside following installation and the outside was painted in a colour to seamlessly blend into the rest of the development.
As the leading manufacturers of cost-effective acoustic and boundary walls, Modular Wall Systems™ designs wall systems that offer a solution for every challenge.
