Soundmesh® G8 facing

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

Sound Absorption Mechanism of Soundmesh G8 with Soundproofing Foam Panel
The Soundmesh G8 facing 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 foam panel.

Traditional 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 superior sound absorption.

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.

Megasorber P has BCA (Buidling Code Australia) Group 2 fire rating as per AS ISO 9705 standard full room fire test. 

See how the Soundmesh G8 acoustic facing blocks out fire:

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.

Important Notice and Disclaimer:

These recommendations are for general guidance only. Materials and installation methods must be tested under actual service conditions to determine their suitability for a particular purpose.

1. Keep Sheets Flat

Sheets must be kept flat during the handling and installation process. Bending or folding sheets will createFF creases on the Soundmesh G8 facing. Once formed, these creases are difficult to remove.

Fireproof Tape for Installation of Soundproofing PanelsAlternatively, a matching Soundmesh G8 tape can be used to seal the edges and joins. The standard Soundmesh G8 tape colours available are: Black, White, Grey (GR) and Sandstone (SS).

Recommendations for applying the Soundmesh G8 tape are:

  • The substrate surface must be flat, dry, free of oil, dust, grease and other contaminants.
  • Soundmesh G8 tape must be firmly pressed against the substrate upon application to ensure the adhesive has full contact with the substrate.
  • The application temperature is recommended to be at least above 10°C.
  • For products with water repellent G8 facing, the G8 tape can be applied with heat and pressure, such as an iron or a hot air-gun plus a pressure roller.

7. Cutting

The product can be hand-cut by a knife or machine-cut by a bench saw or rotating blade cutter with a fine tooth blade.

Cutting panels by machine

If cutting by hand, we recommend using a sharp Stanley and/or serrated knife.

Cuting Panels by Hand

We recommend wearing gloves during cutting. The Soundmesh G8 facing edges may cut or irritate the skin.

8. Cutting Holes

Use a saw hole cutter or a hole puncher as the drill bit to cut holes through the product. A typical hole puncher and drill bit are shown below:

Option 1: Megasorber A200 Fast Drying, High-Tack Adhesive

  • High-tack, high-temperature resistant adhesive
  • Odourless and fast curing
  • Specifically designed to provide instant holding of the FM acoustic panel
  • Apply A200 adhesive on the back side of the acoustic panel (not on the Soundmesh G8 facing).  Important note:  The Soundmesh G8 facing (woven non-combustible fabric) must face the noise.   Apply the glue on the other side of the panel.  
  • Install the panel immediately after the application of the glue. Important note:  A200 is a fast curing glue.  You have approximately 7 minutes to position the panel, before the A200 glue starts to harden and loses tack.
  • Align panel and apply gentle pressure to the panel.   Megasorber A200 instantly holds the panel in position.
  • Adjust and re-position panels as required, within 7 minutes after applying the glue.
  • Once the panel is in place, apply firm and evenly distributed pressure to the panel to ensure it is level.  DO NOT compress the panel with a pressure roller.
  • Shadow-line finish for architectural applications:  we recommend leaving a 15mm to 30mm gap between panels.  DO NOT butt-join panels.
  • Clean any excess A200 adhesive with Megasorber AC5.
  • Allow at least 24 hours for adhesive to cure completely
  • Recommended coverage:
    • about one cartridge (290ml) per 1.2m x 1.2m panel
    • about one and half (1.5) to two (2) sausages (600ml) per 1.2m x 2.4m panel

Please refer to Application Instruction of Megasorber A200 for more details.

Option 2: Megasorber A100 High-Tack Spray-On Adhesive

  • An air-less spray adhesive system
  • Specifically designed for installing Megasorber acoustic panels
  • Supplied in a canister (17.2kg) or as an aerosol (500ml)
  • Estimated coverage: about 99m2 per canister or about 4m2 per aerosol

Please refer to Application Instructions for Megasorber A100 for more details.
