Megasorber Soundmesh® G8A

Fireproof Acoustic Fabric with
Heat Reactive Adhesive Backing for
Perforated and Slotted Panels

Features

Soundmesh G8A fireproof acoustic fabricSoundmesh® G8A is a thin fireproof acoustic lining fabric with a heat reactive adhesive backing for perforated / slotted panels, perforated metal sheets and timber slats.

Soundmesh® G8A is a smart material which breaks the soundwave down to little components, then traps and dissipates the soundwave within the spacer behind it (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australia Patent No. 2009206197). The figure below shows how this soundproofing mechanism works.

The Unique Soundproofing Mechanism of Soundmesh® G8A

Soundproofing Mechanism

Soundmesh® G8A is engineered to have an acoustic impedance tuned specifically for perforated / slotted panels, perforated metal sheets and timber slats. Soundmesh® G8A utilises the latest material technology to maximise sound absorption.

The heat reactive adhesive is specially developed to allow G8A to adhere onto perforated or slotted panels with applied heat. Once laminated, G8A provides the panels with exceptional sound absorption capacity.

Soundmesh® G8A is non-combustible. It has BCA (Building Code of Australia) Group 1 fire Classification. It complies with IMO Resolution A653(16) requirements. It has high temperature resistance up to 550°C.

water and fluid repellent grade

It can be used in outdoor environments without degradation of performance.

Soundmesh® G8A can be supplied with a built-in fluid / water repellent property for easy cleaning and maintenance (product code: Soundmesh® G8A-WR). It can also be supplied without the heat re-active adhesive backing.

It is available in four standard colours: black, white, grey and sandstone. Colour-matching is available to any customized colour, however, minium order quantity applies.

Tech Specs

Soundmesh® G8A on slotted MDF board

The graph below shows how Soundmesh® G8A boosts the sound absorption of a 12mm thick slotted MDF board from NRC of 0.11 to NRC of 0.75:

Sound Absorption of 12mm Slotted MDF Board
(8mm slot with 28.4% opening)
with and without Soundmesh G8A
