Megasorber Composite C14

Soundproofing Foam Barrier Composite with Fireproof Sound-Absorbing Facing



Megasorber soundproofing foam barrier composite with fireproof sound-absorbing facing

Megasorber C14 is 14mm thick soundproofing foam-barrier composite consisting of a patented acoustically tuned fireproof sound absorbing facing Soundmesh® G8 (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australia Patent No. 2009206197) and a flexible noise barrier.

The unique facing material Soundmesh® G8 is inherently fire-resistant. It complies with IMO Resolution A653(16) requirements and has BCA (Building Code of Australia) Group 1 fire Classification and BS 476 Part 4 "Non-combustible" classification. The G8 has high-temperature resistance up to 550°C.

Traditional fireproof faced materials and sound reflecting film facings (such as aluminium foil, mylar film and polyurethane film) have little or zero acoustic properties and tend to block noise from being absorbed by the underlying foam. In contrast, Soundmesh G8 has been engineered and tuned to maximise the sound absorption.

Megasorber C14 provides excellent sound absorption and increases transmission loss thus maximising the soundproofing.

Megasorber C14 has a protective, tough, durable and easy to clean surface. The standard colour is black (colour code = B). Combined with a hydrolysis resistant acoustic foam, it is especially suited for use in hot and humid areas, such as boats or tropical environments.

Megasorber C14 meets with the requirements of GM Holden Australia Specifications HN 2483 - Acoustic Insulator.

Key Features

Australian Made and Owned Soundproofing Acoustic Foam Composite
  • Designed for maximum noise insulation of engine noise insulation (125Hz – 2000Hz)
  • Unique Soundmesh G8 facing, which is fireproof as well as tough and durable.
  • Resists hydrolysis - foam will not rot under hot and humid conditions
  • Easily cut, shaped, fabricated and installed
  • Broad service temperatures:  from -40°C to +120°C

Key Benefits

  • Maximises noise reduction by providing high sound absorption and sound transmission loss
  • Proven efficiency in engine noise reduction
  • Easy to install, ie low installation costs
  • Long service life



High-efficiency sound absorbing and noise insulation material for engine noise reduction in automotive and marine industries.  It is also used for noise reduction in buses, transportation, locomotives, generator enclosures, pipe lagging and duct break-out noise for HVAC.

Case Study of Project Using Megasorber C14

Soundproofing for
Turret Punch Press Machine

Machine Noise Reduction Semi-Enclosure
A soundproofing semi-enclosure was built around the machine

A turret machine generated an unacceptable noise level that carried into the office environment and made communications in the factory difficult. Megasorber designed a soundproofing semi-enclosure around the machine which reduced the noise to a moderate background sound. READ MORE >>

The data listed in this data sheet are typical or average values based on tests conducted by independent laboratories or by the manufacturer. They are indicative only of the results obtained in such tests and should not be considered as guaranteed maximums or minimums. Materials and installation methods must be tested under actual service to determine their suitability for a particular purpose. "Aussie engineered and made" means the products are engineered and made in Australia with globally sourced materials.  “Fireproof ” and “ non-combustible ” mean product has BS 476 Part 4 “Non-combustible” Classification.

Installation Instructions

Important Notice and Disclaimer: These recommendations are for general guidance only. 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.

Knife cut by hand: it is recommended using a sharp Stanley and/or serrated knife. It is recommended to wear gloves during cutting.

The Soundmesh G8 facing edges may cut or irritate the skin.

2. Installing onto Walls or Ceilings

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. We recommend an extra mechanical fixing in addition to the glue when installed on over-head position. Complete with trim or tape joins with colour matching Soundmesh G8 tape.

Caution: for ceiling or overhead applications, a mechanical fastening system is strongly recommended to provide extra support.

3. Edges Finish

Plastic, steel or aluminium U channels can be used to cover the edges. Alternatively, a matching Soundmesh G8 tape is recommended to seal the edges and joints. The product code is Soundmesh G8BK tape (Black colour).
