Soundproofing requirements

The acoustic design for the car park of the St George’s Hospital Aged Care Facility requires a substantial reduction of the car noise in this car park surrounded by many houses. Neighbours complain about excessive noise coming from the car park towards their houses. The ground floor car park has a concrete floor and concrete soffits, with no acoustic treatments. Therefore, superior broad-band sound absorption panels are needed that can tackle low-frequency noise, such as motorbike ramble and car noise.

Aesthetically the acoustic panels need to blend into the existing space.

A water-repellent solution is needed because some sides of the car park are open, so the acoustic panels will be exposed to the elements.


Megasorber FM100W-RG

100mm lightweight acoustic panels with water-repellent Grey Soundmesh® G8 facing.

Megasorber A200

High tack and temperature-resistant adhesive using the latest polymer-alloy technology. Available in sausages and cartridges.


  • High sound absorption capabilities: NRC 1.0.
  • Excellent thermal insulation.
  • AS5637.1 BCA Group 1 fire classification.
  • Water repellent Soundmesh® G8 facing.
  • Lightweight and easy to install.
  • Cost-effective to install.


Megasorber FM100 acoustic panels with grey water-repellent Soundmesh® G8 facing are direct fix installed on the concrete soffit using Megasorber A200 adhesive.

On the side of the car park where the panels are exposed to the elements, the panels are inserted in metal J channels.

The Megasorber tape is used to join panel parts where cutting is needed, for example, around lights and cameras.
