Megasorber Soundmesh® G8A
Fireproof Acoustic Fabric with Heat Reactive Adhesive Backing for Perforated and Slotted Panels
Features
Soundmesh® G8A is a thin fireproof acoustic lining fabric with a heat reactive adhesive backing for perforated / slotted panels and perforated metal sheets.
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 (Patent applied for).
Soundmesh® G8A is engineered to have an acoustic impedance tuned specifically for perforated / slotted panels and perforated metal sheets. Soundmesh® G8A utilises the latest material technology, to maximise sound absorption.
The unique sound absorption mechanism of G8A
Soundmesh® G8A-WR:
water and fluid repellent grade
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.
It can be used in outdoor environments without degradation of performance.
It is available in four standard colours: black, white, grey and sandstone.
Soundmesh® G8A can be supplied with a water / fluid repellent version (product code: Soundmesh® G8A-WR).

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
(90mm air gap, no cavity infill)
(Tested to AS ISO 354-2006 Acoustics:
Measurement of sound absorption in a reverberation room)
Soundmesh® G8A on perforated MDF board at various air-gaps
The graph below shows how Soundmesh® G8A boosts the sound absorption at low frequencies as the air gap increases, resulting a very even sound absorption across the whole frequency spectrum:
Sound Absorption of 12mm Perforated MDF Board
(10mm hole with 25.1% opening)
with and without Soundmesh G8A at Various Air Gaps
(no cavity infill)
(Tested to AS ISO 354-2006 Acoustics:

The Effect of Cavity Infills
The graph below shows how Soundmesh® G8A boosts the sound absorption further when Megasorber acoustic polyester wool or Megasorber P50 (acoustic polyester wool with Soundmesh® G8 facing) is used as cavity infill:
