International Maritime Organization IMO Compliant Fireproof Soundproofing Facing

Megasorber PN

Acoustic Board with
Fireproof Sound-Absorbing Facing



Acoustic Board with Fireproof Sound-Absorbing Facing

Megasorber PN is a semi-rigid sound absorption board with a patented acoustically tuned  fireproof sound absorbing facing Soundmesh® G8 (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australia Patent No. 2009206197).

Soundmesh G8 has been engineered and tuned to maximize the sound absorption. As a result, Megasorber PN provides exceptional high sound absorption, especially at low to mid frequencies.



Sound Absorption Mechanism of Soundmesh G8 with Acoustic Polyester Board

Note:  Traditional fireproof faced materials and sound reflecting solid film facings (such as aluminium foil, mylar film and polyurethane film) have little or zero acoustic properties and block noise from being absorbed by the underlying materials.

Fluid-Repellent Acoustic Facing
Fluid-repellent facing (Optional)

Megasorber PN has BCA (Building Code of Australia) Group 2 Classification. It complies with IMO Resolution A653(16) requirements.

The unique Soundmesh® G8 facing material has BS 476 Part 4 "non-combustible" classification, BCA (Building Code of Australia) Group 1 Fire Classification and ISO 5660 Group 1 Fire Classification. It complies with IMO Resolution A653(16) requirements, and has high-temperature resistance up to 550°C.

Megasorber PN is specifically designed for (1) acoustic backing board for timber battens, timber slats and so on; (2) drop-in ceiling tiles for standard ceiling grid and (3) printable acoustic board.

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

Standard facing colours are: white (W), black (B), grey (G) and sandstone (S). Soundmesh G8 can be colour-matched to any specific colour, however, minimum order quantity will apply.
