School and classroom acoustics in Brisbane
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet. School buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo.
- Classroom RT
- A number, set against room volume, achieved mostly at the ceiling.
- Corridor spill
- Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
- Halls and gyms
- Dual use rooms carrying speech, music and sport, where durability decides the product.

What you are buying, and what it fixes in Brisbane
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet.
School buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo.
Work reaching us from Brisbane is mostly timber housing and renovations, apartments, offices, venues, schools, clinics.
- Houses raised on stumps A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
- Subtropical humidity PET felt does not absorb moisture, shed fibre or feed mould, which matters through a humid summer where mineral products sag.
- Apartments built light and fast The same separating detail repeated across a development. Worth solving on the drawing rather than after settlement.
- Classroom RT A number, set against room volume, achieved mostly at the ceiling.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for school acoustics are on the main product page. This page covers what that means for a project in Brisbane.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Brisbane, ducted systems and split units, with outdoor units close to boundaries where neighbour noise limits apply.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Brisbane, school halls, community centres and church buildings carry assembly, performance and sport in one hard volume.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Brisbane, school buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
What the buildings in Brisbane do to the specification
- Houses raised on stumps
A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
- Subtropical humidity
PET felt does not absorb moisture, shed fibre or feed mould, which matters through a humid summer where mineral products sag.
- Apartments built light and fast
The same separating detail repeated across a development. Worth solving on the drawing rather than after settlement.
- A long sea leg
One of the longer routes we run. Ordering to a real schedule matters, so we quote the full window rather than the port date.
- Assembly and performance rooms
School halls, community centres and church buildings carry assembly, performance and sport in one hard volume.
- School and campus buildings
School buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo.
04 / Room by room
Space by space, for Brisbane briefs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. PET felt does not absorb moisture, shed fibre or feed mould, which matters through a humid summer where mineral products sag.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Wood wool acoustic panels, 400 kg per cubic metre
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. The same separating detail repeated across a development. Worth solving on the drawing rather than after settlement.
- PET felt acoustic panels, 4 to 24 mm
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
For a Brisbane interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate
What the Brisbane climate rules in and rules out
Brisbane is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.

The six errors that cost the most
-
Panels at child height where they get damaged
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating one classroom and leaving the corridor
It sounds like a small detail until the room is finished and the complaint arrives.
-
Choosing a product that cannot take a football
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.

Treating it as a generic Brisbane job
A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
05 / Supply
Getting it to Brisbane, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Port of Brisbane, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Port of Brisbane |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into the Port of Brisbane, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Brisbane projects
What makes school and classroom acoustics different in Brisbane?
School buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo. A timber floor over open air has almost no mass and nothing below it. Adding mass and closing the underfloor does more than anything applied inside the room.
Where should the budget go first on a Brisbane project?
Classroom RT. A number, set against room volume, achieved mostly at the ceiling. Corridor spill. Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
Do you have an office or installation team in Brisbane?
No. We manufacture in India and supply into Brisbane. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Brisbane site?
ships from: Palwal, Haryana, India, arrives at: Port of Brisbane, then a short road run to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
What goes wrong most often on this kind of project?
Panels at child height where they get damaged. Treating one classroom and leaving the corridor.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.

Drawings in, BOQ and a delivered date out
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
