School and classroom acoustics in Auckland
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. Classroom acoustics are taken seriously and open plan learning spaces are common, which makes speech intelligibility the design target.
- 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.

01 / What it is
The product, described honestly, for a Auckland brief
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.
Classroom acoustics are taken seriously and open plan learning spaces are common, which makes speech intelligibility the design target.
Work reaching us from Auckland is mostly apartments and townhouses, offices, hospitality, schools, clinics, studios.
- Apartments built light and fast Townhouse and apartment stock built quickly in timber frame. The separating construction is where noise complaints concentrate.
- Weathertightness shapes the build-up Wall assemblies here are designed around drainage and drying. An acoustic layer has to work with that, not trap moisture in it.
- Volcanic ground, seismic detailing Flexible junctions are required, so a rigid acoustic bridge across a movement joint is not acceptable.
- 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 Auckland.
02 / The build-up
The build-up, layer by layer
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Auckland, heat pumps and ducted systems, with outdoor units close to boundaries in dense suburbs.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Auckland, school halls, marae and community centres carry speech and performance in the same hard room.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 3
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 Auckland, classroom acoustics are taken seriously and open plan learning spaces are common, which makes speech intelligibility the design target.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
What decides the build-up in Auckland
- Apartments built light and fast
Townhouse and apartment stock built quickly in timber frame. The separating construction is where noise complaints concentrate.
- Weathertightness shapes the build-up
Wall assemblies here are designed around drainage and drying. An acoustic layer has to work with that, not trap moisture in it.
- Volcanic ground, seismic detailing
Flexible junctions are required, so a rigid acoustic bridge across a movement joint is not acceptable.
- The port is in the city
Direct sea into Auckland keeps the road leg short, though the sea leg itself is long and we quote it fully.
- Assembly and performance rooms
School halls, marae and community centres carry speech and performance in the same hard room.
- School and campus buildings
Classroom acoustics are taken seriously and open plan learning spaces are common, which makes speech intelligibility the design target.
04 / Room by room
Room by room, on a typical Auckland job
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Townhouse and apartment stock built quickly in timber frame. The separating construction is where noise complaints concentrate.
- 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. Wall assemblies here are designed around drainage and drying. An acoustic layer has to work with that, not trap moisture in it.
- 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. Flexible junctions are required, so a rigid acoustic bridge across a movement joint is not acceptable.
- PET felt acoustic panels, 4 to 24 mm
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
Durability in Auckland, before acoustics is discussed
Auckland is cool and damp, with long heating seasons and cold external walls, and that narrows the material list before acoustics is discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The failure we design against here is condensation behind linings in older, poorly insulated stock.
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.
06 / Worth knowing
Where this kind of project usually fails
-
Panels at child height where they get damaged
This is the one that comes back as a second fit-out rather than a snag.
-
Treating one classroom and leaving the corridor
This is the one that comes back as a second fit-out rather than a snag.
-
Choosing a product that cannot take a football
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
Treating it as a generic Auckland job
Townhouse and apartment stock built quickly in timber frame. The separating construction is where noise complaints concentrate.
05 / Route to site
Supply into Auckland, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Auckland, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Auckland |
| 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 direct into Auckland, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Auckland projects
What makes school and classroom acoustics different in Auckland?
Classroom acoustics are taken seriously and open plan learning spaces are common, which makes speech intelligibility the design target. Townhouse and apartment stock built quickly in timber frame. The separating construction is where noise complaints concentrate.
Where should the budget go first on a Auckland 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 Auckland?
No. We manufacture in India and supply into Auckland. 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 Auckland site?
ships from: Palwal, Haryana, India, arrives at: Auckland, 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.
