Megasorber FG

Lightweight Acoustic Foam Panel with
Fireproof Sound-Absorbing Facing and
Optional Self-Adhesive Backing


Insulation Acoustic FG Foam

Megasorber FG acoustic foam panels utilise a patented fireproof sound-absorbing facing material Soundmesh® G8 (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australia Patent No. 2009206197) to provide maximum sound absorption especially at low to mid frequencies.

The unique facing material Soundmesh® G8 has high temperature resistance up to 550°C and Building Code Australia (BCA) Group 1 Fire Classification. It complies with IMO Resolution A653(16) requirements.

Hear how Megasorber FG50SS effectively reduced the reverberation noise in a large hall:


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 is engineered and tuned to maximise sound absorption.

The Unique Sound Absorption Mechanism of Megasorber FG

Sound Absorption Mechanism of Soundmesh G8 with Soundproofing Foam Panel
The Soundmesh G8 facing allows the noise through, breaks down the sound waves into little components and traps the noise inside where it is absorbed by Megasorber's acoustic foam panel.

Soundmesh® G8 facing

Megasorber FG uses hydrolysis resistant acoustic foam and has high durability (long service life) in hot and humid conditions such as marine and tropical environments. The foam is capable of operating continuously from -40°C to +120°C and intermittently to 140°C. Megasorber FG meets the requirements of GM Holden Australia Specifications HN 2483 - Acoustic Insulator.

The built-in fluid / water repellent property of Soundmesh G8 provides for easy cleaning and maintenance of the facing and makes it suitable for outdoor applications. A non fluid-repellent G8 facing option is also available.

Soundmesh G8 has four standard colours of white (WH), black (BK), grey (GR) and sandstone (SS). It can also be colour-matched to any specific colour, however a minimum order quantity will apply.

Fireproof Tape for Installation of Soundproofing PanelsAlternatively, a matching Soundmesh G8 tape can be used to seal the edges and joins. The standard Soundmesh G8 tape colours available are: Black (BK), White (WH), Grey (GR) and Sandstone (SS).

Recommendations for applying the Soundmesh G8 tape are:

  • The substrate surface must be flat, dry, free of oil, dust, grease and other contaminants.
  • Soundmesh G8 tape must be firmly pressed against the substrate upon application to ensure the adhesive has full contact with the substrate.
  • The application temperature is recommended to be at least above 10°C.
  • For products with water repellent G8 facing, the G8 tape can be applied with heat and pressure, such as an iron or a hot air-gun plus a pressure roller.
