Megasorber Soundmesh® G8 & G8A

Fireproof Sound-Absorbing Material

Features

Megasorber G8 fireproof sound adsorbing fabric

Soundmesh® G8 is a patented thin, tough material with unique acoustic and fireproof properties (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australia Patent No. 2009206197).

Acoustic Properties

Soundmesh® G8 is a smart material which breaks the soundwave down to smaller components, then traps and dissipates the soundwave within the spacer behind it. The acoustic impedance of G8 is tuned to maximise sound absorption.

Soundmesh® G8 is specifically designed to suit various applications:

  • Acoustic lining material behind timber slats, perforated / slotted panels (MDF, plywood, FCS) and perforated metal panels. It converts these decorative panels into sound absorbing panels. Soundmesh G8 can be stapled, glued or heat-bonded onto the back of such panels.
  • Acoustic facing material to further enhance the acoustic performance of traditional acoustic materials such as rockwool and glasswool. Soundmesh G8 provides consistent acoustic performance by eliminating the batch variation of the base materials.
  • Acoustic fabric to be used as clouds, curtains, banners and so on.
  • Tuned sound absorber for absorbing sound at targeted frequencies such as in concert hall applications.

Fireproof Properties

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

Soundmesh® G8 will not burn nor melt after exposed to naked flame. It also prevents the foam behind it from burning by cutting out the fire.

IMPORTANT NOTICE AND DISCLAIMER

Specifications are subject to change without notice. Please contact us for the latest version. "Fireproof", "Non-flammable", "Non-combustible" means the product has successfully passed AS/NZS 3837, IS0 5660-1, ASTM E1354 Group 1 fire rating (AWTA test report No. 7-566397-CV). Patented Soundmesh G8 (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australia Patent No. 2009206197). The data listed in this data sheet are typical or average values based on tests conducted by independent laboratories or by the manufacturer. They are indicative only of the results obtained in such tests and should not be considered as guaranteed maximums or minimums. Materials and installation methods must be tested under actual service to determine their suitability for a particular purpose. "Aussie engineered" means the products are engineered in Australia with globally sourced materials.

Installation Instructions

These recommendations are for general guidance only. Installation methods must be tested under actual service conditions to determine their suitability for that particular purpose.

Soundmesh G8

Spray-on or roll-on adhesives

Soundmesh G8 can be glued on with spray-on adhesive or roll-on adhesive.

We recommend applying this type of adhesive onto the substrate only. If the glue is to be applied onto the Soundmesh G8, then use only a light coating of adhesive spray. An excessive amount of glue on the Soundmesh G8 will affect the acoustic performance.

Staple with a staple gun

Soundmesh G8 must be fully tensioned before applying the staples. Photos below show typical applications.

Important note: the acoustic performance will be affected if the Soundmesh G8 is not fully tensioned.

Soundmesh G8A

Soundmesh G8A consists of two key components as shown below:

  1. Soundmesh G8 base acoustic fabric (black) and
  2. Heat reactive web adhesive (white)

Soundmesh G8 with adhesive backing

The heat reactive web adhesive is pre-attached onto the Soundmesh G8 base fabric.

Important note: do not remove this web adhesive from the Soundmesh G8 base fabric.

The melting temperature is approximately 115°C for the heat reactive web adhesive. Once activated, the web adhesive changes from white to transparent /clear.

Note: this web adhesive can also be reactivated with heat.

The Soundmesh G8 based fabric has excellent thermal insulation properties. The required heating temperature may need to be much higher than the melting temperature in order to activate the heat reactive web adhesive.

Recommended methods to bond the Soundmesh G8A onto perforated / slotted panels

Surface preparation:

  • The surface of the perforated/slotted panels must be clean and free of oil, moisture, dust and any other contamination. Clean the substrate surface with Megasorber AC5 adhesive cleaner or equivalent.
  • Ensure panels are flat and have an even surface.
  • Panels with glossy, mirror-like surfaces and powder coated metal panels: The heat reactive adhesive does not suit these surfaces. In order to create bonding, it is recommended to sand or roughen up the glossy surfaces, then clean the surface with Megasorber AC5 or equivalent.

Heating and temperature:

  • Pre-heat the substrates and the Soundmesh G8A to around 140ºC before bonding.
  • Once the heat-reactive web adhesive changes from white to transparent, it indicates that the heating temperature reaches the required bonding temperature.
  • If the heat-reactive web adhesive remains white after the bonding process, it indicates that the heating temperature needs to be increased.

Infrared heating unit with press rollers: Heat the G8A with the perforated or slotted panel with infrared radiator and press by using a roll. One of the typical applications is shown below:

White Soundmesh G8 being applied to the underneath perforated panel with an infrared heating unit


A nipping machine with infrared heating or hot rollers: Activate the G8A heat-reactive adhesive with the infrared heating or hot rollers and bond the G8A onto the panel via feed rollers.

Ironing press: Set ironing press at 150°C to 170°C, with 200 to 250 mbar pressure for at least 10 seconds residual time.

Hot iron: Set the hot iron to maximum temperature, typically between 150°C to 175°C, and iron the G8A onto the back of the perforated or slotted panel with firm pressure.
