Megasorber P
Megasorber P is a sound absorption material consisting of a patented acoustically tuned fireproof sound absorbing facing Megasorber Soundmesh® G8 (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australia Patent No. 2009206197) and environmentally-friendly acoustic polyester-wool.
The diagram below shows how Soundmesh G8 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 polyester panel.
The Unique Sound Absorption Mechanism of Megasorber P
Megasorber P has BCA (Building Code of Australia) Group 2 Classification with Average Specific Extinction Area less than 250 m2/kg. It complies with IMO Resolution A653(16) requirements.
The unique facing material, Soundmesh® G8, has BS 476 Part 4 "Non-combustible" classification, BCA Group 1 Fire Classification and ISO 5660 Group 1 Fire Classification. It complies with IMO Resolution A653(16) requirements. It has high-temperature resistance up to 550°C.
See how the Soundmesh G8 acoustic facing blocks out fire:
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 block noise from being absorbed by the underlying polyester. In contrast, Soundmesh G8 has been engineered and tuned to maximize the sound absorption. As a result, Megasorber P provides exceptional high sound absorption at low to mid frequencies.
Megasorber P has high durability in hot and humid conditions (long service life). It provides excellent thermal insulation. It has a protective, tough and durable surface. The built-in fluid/water repellent (optional) property of Soundmesh G8 provides for easy cleaning and maintenance of the facing and makes it suitable for outdoor applications.
Standard facing colours: 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.
