BarrierWall, a noise wall system from Modular Walls was used to overcome multiple challenges at a development site adjoining Narellan Road in Mount Annan, NSW.

The client sought a 3.6m noise wall between lot developments to be installed quickly and easily. However, there were several problems including overhead power lines and underground services, which barred the use of heavy beams in the design, though the wall panels needed to achieve a minimum of 15 kg/m² density. Additionally, the client faced tight time constraints between DA approval and handover.

Modular Walls designed and delivered a customised acoustic solution, with modified installation methods to fit the client’s specific needs.

The BarrierWall system by Modular Walls overcame all the challenges without any compromise on the premium aesthetic. The lightweight modular system could be installed in just two weeks without the use of a crane.

Modular Walls’ BarrierWall runs almost 90m in length and incorporates proprietary AcoustiMax panels. The noise barrier provides high quality sound attenuation from the traffic on Narellan Road, a major arterial road in the area, and is perfectly integrated with an existing wall.
