Soundmesh Â® G8 is a patented engineered material that is thin and tough with unique acoustic and fireproof properties (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australia Patent No. 2009206197). The acoustic impedance of G8 is tuned, utilising the latest material technology, to maximise sound absorption.oundmesh Â® G8 is a smart material with a solid membrane in appearance, but has a âmicroporousâ design to allow the noise to filter through. Whilst allowing the noise through, Soundmesh G8 breaks down the sound waves into little components and traps the noise inside.
