Sound Absorbing Panels Megasorber P for external applications

See and hear how Megasorber P can effectively reduce reverberation in outdoor applications.

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 maximise sound absorption. As a result, Megasorber P is a superior sound absorbing panel.

The unique facing material, Soundmesh®® G8, has AS 1503.1 con-combustibility fire rating, 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 NCC (National Construction Code) Group 2 fire rating as per AS ISO 9705 standard full-room fire test.

Megasorber P has high durability in hot and humid conditions. It provides excellent thermal insulation. It has a protective, tough and durable surface. It has a hydrophobic polyester fibre base. The built-in fluid/water repellent (optional) property of Soundmesh® G8 provides easy cleaning and maintenance of the facing and makes it suitable for outdoor applications.

  3. Product code with optional extra:
  4. G8 facing may have a stripy appearance and creases. Hairline creases may appear on the facing when The creases do not affect the acoustic performance.
  5. There are colour variations between batches; whilst we take every care to minimise batch-to-batch variation, in some instances, variation may be unavoidable and will occur.
  6. Dimensional change will occur in the FM foam substrate with a change in relative humidity and temperature; this may cause creasing on the Soundmesh® G8 facing. The creases do not affect acoustic performance.
  7. Thickness tolerance is ± 5%, and sheet dimension tolerance is ± 1%.

Installation instructions and care & maintenance guide

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

Keep acoustic panels flat. Panels 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.

Cutting (if required). The panel can be hand-cut by a knife (sharp utility knife or similar), or machine-cut by a bench saw or rotating blade cutter with a toothless blade.

Note: It is recommended to wear gloves during cutting. The Soundmesh® G8 facing edges may irritate or cut the skin.

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

Install the panels direct-fix using Megasorber A200 or A100 adhesives, with express finish edges or between panels using powder-coated aluminium trim.

Clean dirt and marks on the Soundmesh® G8 facing with Megasorber

M8 Clean block and water. Dry with a microfiber cloth. Remove excessive adhesive on hands, cloth or equipment with Megasorber AC5.

Direct-fix acoustic panels using Megasorber A200 adhesive.

Available in 600ml sausage for caulking gun and 290ml cartridges for cartridge gun.

  1. Apply adhesive on the back of the acoustic panel (NOT on the Soundmesh® G8 facing).
  2. Install the panel immediately after application of the

Application Pattern

Full-size panel (1.2m x 2.4m) adhesive application 

Minimum bead size (glue width) = 10mm to 15mm diameter. Recommended usage: approx. 1.5 to 2 sausages per full-size panel (1.2m x 2.4m), or approx. 2-3 cartridges per full-size panel.

Direct-fix with Megasorber A100

Spray Adhesive

  1. Connect a hose and spray gun to the new canister. Roll the canister backwards and forwards vigorously for 1-2 minutes to ensure the adhesive has not settled or separated during transit.
  2. Spray adhesive onto the back of the acoustic panel (not on the Soundmesh® G8 facing). Spray one coat to seal the porous surface vertically and then a second coat horizontally to achieve maximum adhesive contact.
  3. Spray adhesive on the substrate
  4. Allow adhesive to dry thoroughly. The adhesive should be touch-dry in 3-5 minutes (depending on conditions).
  5. Bond both surfaces together within 10 minutes of the adhesive being touch-dry.
  6. Apply uniform pressure over the surface.

Spray patterns

 

Note: we recommend A100 on a smooth surface, such as refrigeration panels, plasterboards and metal panels. A100 is not suitable for uneven or textured surfaces. For uneven or textured surfaces, such as concrete soffit and brickwork, we recommend A200 adhesive.
