Acosorb · sole Australian licence
Acoustic absorption with nothing to see.
A seamless acoustic spray and plaster system applied directly to the substrate. No tiles, no suspension grid, no perimeter trim, no visible joint. NRC 0.95 at 35 mm, αw 1.00 in a 35 mm build-up, in the colour on your schedule.

The whole range is made from 100% recycled cellulose fibre — not part-recycled, and not a recycled option sitting alongside a virgin one. Every standard colour, Oman Grey included.
CIUR declaration · confirmed by TZÚS PragueThe Green Building Council of Australia assigns Acosorb products a Responsible Products Value of 9 — the figure a Green Star project claims against.
Green Star · the GBCA assigns the valueGroup 1 to AS 5637.1, so it is accepted on exit paths and in fire-isolated stairs where most linings are not.

The system
Two systems, one appearance.
Acospray is a binding agent and recycled cellulose fibre, sprayed on in crossed layers and finished to one of four textures — from a float finish almost indistinguishable from set plasterboard, through to an open, medium-coarse structure. It can go on in mass, or over a mineral wool absorber where more low-frequency performance is needed.
Acoplaster F is a mineral plaster over a 30 mm mineral wool board, bonded full-surface and finished with a 2 mm sanded plaster coat. It is the smoothest surface in the range — specify it where the ceiling has to read as a plastered plane and nothing else.
Both are applied and finished in a single visit by our own applicators, trained and certified by Acosorb in the Netherlands. Both are locally repairable — damage is made good by reapplying material, sanding and blending, rather than by replacing a panel and living with the colour difference.
Made from waste paper, not new fibre.
Every finish in the range is made from recycled fibre.
Not a recycled option sitting beside a virgin one — the whole range, and every standard colour in it. Black, Oman Grey, ILA Grey, Cool Grey and Denim Blue are all named in the declaration. The fibre is ECO Cellulose, and the manufacturer’s declaration is independently confirmed by TZÚS Prague, the Technical and Test Institute for Construction. Both the fibre processing and the product manufacture are ISO 14001 certified.
Five finishes, and a recycled feedstock.
Compare the range →Same material family throughout. What changes is the grain, the build range and how much of the room it absorbs — so pick the texture the design wants, then set the thickness the acoustics need.

Against the alternatives
Where a sprayed system wins, and where it does not.
Acoustic panels and suspended grid do things a seamless system cannot. This is the honest comparison — if a project needs full ceiling void access, a grid is the right answer and we will say so.
| Acosorb | Acoustic panels | Suspended tile | Sprayed cellulose | |
|---|---|---|---|---|
| Visible joints | None | Yes | Yes — full grid | None |
| Curved / irregular geometry | Yes | Limited | No | Yes |
| Peak absorption | NRC 0.95 · αw 1.00 | Varies by product | Varies by product | Varies by product |
| Colour | Any, pigment-matched | Manufacturer range | White, limited | Limited |
| Ceiling void access | None — services accessed elsewhere | Partial | Full | None |
| Local repair | Yes, blended in | Panel swap | Tile swap | Variable |
| Fire rating | Group 1 — AS 5637.1 | Varies by product | Varies by product | Varies by product |
| Applied by | Licensed applicator only | Any fixer | Any ceiling fixer | Specialist |
Absorption figures are manufacturer-published for the Acosorb range. Comparison columns are generic — panel and tile performance varies widely by product and plenum depth.
Where it goes
Rooms where people have to hear each other.
Workplace
Open plan, boardrooms and collaboration space, where speech intelligibility across a floor plate is the whole brief.
Vercom · Unilever · Greenpeace — Acosorb International
Hospitality
Dining rooms, bars and hotel lobbies. Controls reverberation without altering the interior the designer drew.
Die Weinbar · Beso by Simonis — Acosorb International
Retail & showroom
High-footfall spaces with hard surfaces, where the ceiling has to disappear into a considered fit-out.
Stone Island · Audi — Acosorb International
Health & aged care
Wards, waiting areas and consulting rooms. Cleanable, repairable in place, and applied without a grid to trap dust.

The applicator
One licence, held in Australia.
McPherson Coatings holds the exclusive Australian applicator licence for the Acosorb system. We supply and install nationally, and we are the point of contact for specification, samples, installation and aftercare.
Our applicators are trained and certified by Acosorb. Application technique determines the finish as much as the material does.
Send a ceiling plan and a target reverberation time. We come back with product, thickness and a fixed price.
Sample boards in the colours under consideration, at a size worth looking at, before anything is ordered.
Tested to AS 5637.1 and classified Group 1 — the highest group, accepted for exit paths and fire-isolated stairs.
Performance and adhesion, warranted in writing and issued at handover with the maintenance schedule.
