Megasorber FM  Sound Absorbing Panel

Lightweight & Inherently Fire-Resistant 


Acoustic panel, lightweight, fireproof
Megasorber FM acoustic panels with white, sandstone, grey and black Soundmesh G8 facing

Megasorber FM soundproofing panels provide superior acoustic and thermal insulation, and are extremely lightweight, making them easy to handle, cut and install for architectural and engineering applications.

Highest fire rating (BCA Group 1)

Megasorber FM is inherently fire-resistant and has Building Code Australia (BCA) Group 1 fire rating as per AS 5637.1-2015 and ISO 5660 Group 1 fire classification.

Fireproof Acoustic Panels
No ignition, melting, dripping or spread of flame when exposed to fire: the front and back of FM panel 

Superior Acoustic Performance

Fireproof Soundproofing MaterialThe FM panel utilizes our patented sound absorbing facing material Soundmesh G8 to provide maximum sound absorption especially at low to mid frequencies (U.S. Patent No. 8167085, Canadian Patent No. 2674986, Australian Patent No. 200926197).

The unique Soundmesh G8 facing is extremely tough and durable.  It is inherently fire resistant.

Traditional fireproof faced materials and 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 foam. In contrast, Soundmesh G8 is engineered and tuned to maximize the sound absorption.

Exceptionally High Thermal Insulation

Megasorber FM is engineered with an extremely fine cell structure to trap air and block heat transfer. It provides exceptional thermal insulation, making it one of the most effective lightweight thermal insulation materials.

Heat, Aging and UV Resistant

The Megasorber FM base foam has excellent heat, UV and aging resistance. It can withstand up to 240°C (short time) without decomposition and up to 140°C continuous operating temperature without any distortion.

Megasorber FM is very durable (long service life) in hot and humid conditions such as marine and tropical environments.

Optional fluid-repellent facing

Water-Repellent G8 Facing (Optional)

A fluid/water repellent Soundmesh G8 is also available. Standard facing colours are white, grey, sandstone and black.

Handling, Installation and Maintenance

Megasorber FM acoustic foam is extremely lightweight and self-supporting, making it easy to handle, cut and install. The Soundmesh G8 facing is protective, tough and durable.  Finger marks, dirt marks and surface contamination can be easily removed and cleaned using Megasorber Clean M8 block.  The built-in fluid/water repellent property (optional) of Soundmesh G8 provides for easy cleaning and maintenance making it ideal for outdoor applications.

FM 25 W-RW- DS

For example:
Megasorber FM25W-RW: 25mm thick, off-white base, water repellent, white Soundmesh G8 facing.

Megasorber FM25W-RW-DS: 25mm thick, off-white base, water repellent, white Soundmesh G8 facing on both sides.

  1. Water/fluid* repellent facing is recommended for easy surface cleaning.
    *Please note: does not include petroleum or solvent based fluids.
  2. G8 facing may have some stripy appearance. Hairline creases may appear on the facing when handling.       
  3. There are colour variations between batches, especially for the grey and sandstone colours. Soundmesh G8 facing made from different batches may be difficult to colour match.
  4. Thickness tolerance is ±5% and sheet dimension tolerance is ±1%.
  5. Other sheet sizes available are: 1200mm x 1200mm and 1200mm x 600mm (1195mm x 595mm if packed in boxes). We can  cut panels to any size and any shape using our CNC cutting technology, however, extra cutting charges apply.
  6. Dimensional change will occur in the FM foam substrate with change in relative humidity and temperature, this may cause creasing on the Soundmesh G8 facing.  The creases do not affect the acoustic performance.

Please contact us for the latest version.  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 and made" means the products are engineered and made in Australia with globally sourced materials.  “Fireproof ” and “ non-combustible ” mean product has BS 476 Part 4 “Non-combustible” Classification.

Installation Instructions

The following recommendations are for general guidance only. Installation methods must be tested under actual service conditions to determine their suitability for a particular purpose. We recommend installing panels in accordance with the appropriate procedures as approved by Megasorber.

1. Keep Sheets Flat

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

2. 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

Knife cut 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 irritate or cut the skin.

3. Direct-Fix: Installing Panels with Adhesives

Substrate Surface Preparation

The surface must be flat, dry and free of oil, dust, grease and other contaminants. Clean substrate with Megasorber AC5 or similar.

Megasorber AC5 Adhesive Cleaner is recommended for adhesive removal and surface cleaning.

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.  DO NOT peel off the Soundmesh G8 facing. 
  • 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.

6. Seal Joints With Colour-Matching Self-Adhesive Tape

Fireproof Tape for Installation of Soundproofing Panels
Soundmesh G8 Tape

A matching Soundmesh G8 Tape can be used to seal the edges and joins. The standard Soundmesh G8 colours available are: Black (B), White (W), Grey (G) and Sandstone (S).

Recommendations for applying the Soundmesh G8 tape:

  • 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 ambient temperature for application is recommended to be at least above 10°C.
  • For products with water / fluid 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.
