HVAC, plant and machine noise control in Sydney
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. Ducted systems and split units, with outdoor units close to boundaries where neighbour noise limits apply.
- 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 product
What this material is and where it earns its place in Sydney
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.
Ducted systems and split units, with outdoor units close to boundaries where neighbour noise limits apply.
Work reaching us from Sydney is mostly apartment developments, offices, venues, schools, clinics, studios.
- Apartments at volume The same separating detail repeated across large developments. When it underperforms it underperforms in every unit, and that becomes a defect conversation.
- Mixed construction Concrete frames with lightweight internal walls. The frame blocks, the partitions often do not, and people assume the opposite.
- Venues under homes Late trading beneath apartments built around them, so the separating floor decides the hours.
- 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 Sydney.
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 Sydney, ducted systems and split units, with outdoor units close to boundaries where neighbour noise limits apply.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
Layer 2
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Sydney, school halls, community centres and church buildings carry assembly, performance and sport in one hard volume.
Independent leaf. A second wall that does not touch the first. Nothing else comes close for the money.
-
Layer 3
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Sydney, school buildings run hard floors and high ceilings, and open plan learning areas make speech intelligibility the central problem rather than echo.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
Architects working in Sydney usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / On the ground
What we see driving Sydney briefs
- Apartments at volume
The same separating detail repeated across large developments. When it underperforms it underperforms in every unit, and that becomes a defect conversation.
- Mixed construction
Concrete frames with lightweight internal walls. The frame blocks, the partitions often do not, and people assume the opposite.
- Venues under homes
Late trading beneath apartments built around them, so the separating floor decides the hours.
- A long sea leg
One of the longer routes we run. Ordering to a real schedule matters, so we quote the full window.
- Plant and HVAC
Ducted systems and split units, with outdoor units close to boundaries where neighbour noise limits apply.
04 / Room by room
What each space in a Sydney project needs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. The same separating detail repeated across large developments. When it underperforms it underperforms in every unit, and that becomes a defect conversation.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Wood wool acoustic panels, 20 mm
- Acoustic foam and BassBloc, 100 kg per cubic metre
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. Concrete frames with lightweight internal walls. The frame blocks, the partitions often do not, and people assume the opposite.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Wood wool acoustic panels, 400 kg per cubic metre
- Acoustic foam and BassBloc, 100 to 500 Hz
-
At the receiver
Only after the first two, and only for what is left. Late trading beneath apartments built around them, so the separating floor decides the hours.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Wood wool acoustic panels, 0.30
- Acoustic foam and BassBloc, 0.85
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Conditions
Why the climate in Sydney changes the material, not the target
Sydney 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.
On a Sydney job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Straight talk
What we watch go wrong on jobs like this
-
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
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
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 Sydney job
The same separating detail repeated across large developments. When it underperforms it underperforms in every unit, and that becomes a defect conversation.
05 / Logistics
What the route into Sydney actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Port Botany, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Port Botany |
| 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 Port Botany, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Sydney projects
What makes HVAC, plant and machine noise control different in Sydney?
Ducted systems and split units, with outdoor units close to boundaries where neighbour noise limits apply. The same separating detail repeated across large developments. When it underperforms it underperforms in every unit, and that becomes a defect conversation.
Where should the budget go first on a Sydney 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 Sydney?
No. We manufacture in India and supply into Sydney. 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 Sydney site?
ships from: Palwal, Haryana, India, arrives at: Port Botany, 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
Tell us the room, we will tell you the build-up
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
