Fireproof Soundproofing Facing

Megasorber C50

Foam-Barrier-Foam Soundproofing Composite with Fireproof Acoustic Facing



Megasorber multi-functional composite

Megasorber soundproofing composites are specially designed for marine noise reduction. This Megasorber composite consists of 25mm thick acoustic foam with black acoustic facing, a flexible high mass noise barrier, 25mm thick decoupling acoustic foam and self-adhesive backing (optional). The soundproofing composite development results in increased sound transmission and sound absorption to maximise the noise reduction.

Megasorber soundproofing composites have a patented fireproof sound-absorbing Soundmesh® G8 facing (US patent No. 8167085 and Australian Patent No. 2009206197), which has been engineered to provide maximum sound absorption at low to mid frequencies. This facing complies with IMO Resolution A653(16) requirements. It is extremely tough and durable, protecting the composite from fluids and dust contamination and/or any mechanical damage.

Megasorber composites are manufactured from a hydrolysis resistant acoustic foam. The composite is especially suited for use in wet and humid areas, such as marine or tropical environments. Megasorber A200 adhesive is recommended to easy installtion. For ceiling or overhead applications, a mechanical fastening system is strongly recommended to provide extra support.

Key Features

Water-Repelling Acoustic Facing
Built-in Fluid / water-Repelling Acoustic Facing (optional)
  • Unique fireproof sound-aborbing Soundmesh G8 facing, complying with IMO Resolution A653(16) requirements.
  • Designed for maximum noise insulation of marine engine noise insulation (125Hz – 2000Hz);
  • Resists hydrolysis - foam will not rot under hot and humid conditions;
  • Resists liquids, dusts and sprays;
  • Tough and inherently fire-resistant facing;
  • Easily cut, shaped, fabricated and installed;
  • Water repellent Soundmesh G8 is available.

Key Benefits

Australian Made and Owned Soundproofing Composite
  • Maximises noise reduction by providing high sound absorption and sound transmission loss.
  • Fully tested and proven efficiency in marine noise reduction.
  • Easy to install, ie low installation costs.
  • Long service life.


High efficiency sound absorbing and noise insulation material for noise reduction in marine industries. It can also be used for noise reduction in automotive, buses, transportation, locomotives, generator enclosures, reverberation control in commercial and industrial buildings.

Case Study of Project Using Megasorber C50

Soundproofing for
Reclaimer Operator Cabins

Soundproofing Machinery Noise Problem
Operator Cabin Required Soundproofing from Noise of Reclaimer

Operators of the reclaimers at Port Kembla Coal Terminal were subjected to excessive noise as their steel plated cabins are located close to the bucket wheel and drive components. Megasorber's soundproofing products reduced the noise and improved thermal insulation and overall aesthetics. READ MORE >>

Installation Instructions

Important Notice and Disclaimer: These recommendations are for general guidance only. Materials and installation methods must be tested under actual service conditions to determine their suitability for a particular purpose.

1. Cutting

The product can be hand-cut by a knife or machine-cut by a bench saw or rotating blade cutter with a fine tooth blade. If cutting by hand, we recommend using a sharp Stanley and/or serrated knife.

We recommend wearing gloves during cutting. The Soundmesh G8 facing edges may cut or irritate the skin.

2. Edge Finish

Plastic, steel or aluminium U channels can be used to cover the edges. Alternatively, a matching Soundmesh G8 tape can be used to seal the edges and joins. The standard Soundmesh G8 tape colours available are: Black (B), White (W), Grey (G) and Sandstone (S).

3.Megasorber A200 adhesive:

Megasorber A200 High-Tack, High-Temperature Resistant Adhesive is recommended to adhere the product onto the substrate.

Alternatively, Megasorber A100 High-Tack Spray Adhesive is recommended if a spray-on adhesive is preferred. 

A mechanical fastening system is recommended to provide extra support for overhead positions.
