HVAC, plant and machine noise control in Auckland
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space. Heat pumps and ducted systems, with outdoor units close to boundaries in dense suburbs.
- At source
- Enclosure, barrier or anti vibration mounts at the machine.
- In the path
- Duct lining, attenuators and lagging on the first run out of the plant.
- At the receiver
- Only after the first two, and only for what is left.

01 / The material
What this material is and where it earns its place in Auckland
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space.
Heat pumps and ducted systems, with outdoor units close to boundaries in dense suburbs.
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.
- At source Enclosure, barrier or anti vibration mounts at the machine.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for HVAC and plant noise control are on the main product page. This page covers what that means for a project in Auckland.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Auckland, heat pumps and ducted systems, with outdoor units close to boundaries in dense suburbs.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Auckland, school halls, marae and community centres carry speech and performance in the same hard room.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Auckland, classroom acoustics are taken seriously and open plan learning spaces are common, which makes speech intelligibility the design target.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
If you are specifying for a Auckland project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What the buildings in Auckland do to the specification
- 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.
- Plant and HVAC
Heat pumps and ducted systems, with outdoor units close to boundaries in dense suburbs.
04 / Room by room
Space by space, for Auckland briefs

At source
Enclosure, barrier or anti vibration mounts at the machine. Townhouse and apartment stock built quickly in timber frame. The separating construction is where noise complaints concentrate.

In the path
Duct lining, attenuators and lagging on the first run out of the plant. Wall assemblies here are designed around drainage and drying. An acoustic layer has to work with that, not trap moisture in it.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic foam and BassBloc, 100 to 500 Hz
-
At the receiver
Only after the first two, and only for what is left. Flexible junctions are required, so a rigid acoustic bridge across a movement joint is not acceptable.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Acoustic foam and BassBloc, 0.85
For a Auckland 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 Auckland climate rules in and rules out
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.
On a Auckland job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Straight talk
Where this kind of project usually fails
-
Absorption on the office wall for a plant room problem
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Lagging a duct that is carrying the noise as breakout from the fan
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Ignoring structure borne vibration through the mounts
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 / Supply
How material reaches a Auckland 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 HVAC, plant and machine noise control different in Auckland?
Heat pumps and ducted systems, with outdoor units close to boundaries in dense suburbs. 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?
At source. Enclosure, barrier or anti vibration mounts at the machine. In the path. Duct lining, attenuators and lagging on the first run out of the plant.
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?
Absorption on the office wall for a plant room problem. Lagging a duct that is carrying the noise as breakout from the fan.
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.
Next step
Send a plan and a section, get a real build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
