HVAC, plant and machine noise control in Jakarta
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. Split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
- 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.

- From a plan and a section, within 48 hours

The product, described honestly, for a Jakarta brief
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.
Split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
Work reaching us from Jakarta is mostly towers and offices, apartments, hotels, hospitals, schools, studios.
- Noise arrives from outside Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
- Concrete towers, live interiors The structure blocks well. The problem is tile, glass and stone inside making the room ring.
- Standby generation Power backup sits close to occupied space in most commercial buildings and runs often enough to matter.
- 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 Jakarta.
02 / The build-up
The build-up, layer by layer
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Jakarta, split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
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 Jakarta, places of worship, function halls and community buildings are large hard rooms carrying amplified speech and music.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Jakarta, classrooms are hard, naturally ventilated and open to corridor and street noise, so absorption alone will not fix intelligibility.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
Architects working in Jakarta 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 / Local conditions
What the buildings in Jakarta do to the specification
- Noise arrives from outside
Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
- Concrete towers, live interiors
The structure blocks well. The problem is tile, glass and stone inside making the room ring.
- Standby generation
Power backup sits close to occupied space in most commercial buildings and runs often enough to matter.
- The port is in the city
Tanjung Priok is close, which keeps the road leg short and the landed cost predictable.
- Plant and HVAC
Split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
04 / Room by room
Where the money goes on a Jakarta project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. The structure blocks well. The problem is tile, glass and stone inside making the room ring.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- 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
-
At the receiver
Only after the first two, and only for what is left. Power backup sits close to occupied space in most commercial buildings and runs often enough to matter.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
For a Jakarta interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Conditions
What the Jakarta climate rules in and rules out
Jakarta is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
On a Jakarta job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
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 Jakarta job
Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
05 / Supply
Getting it to Jakarta, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Tanjung Priok, then a short road run into the city |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Tanjung Priok |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Tanjung Priok, then a short road run into the city. Air freight for samples and urgent quantities.
Questions from Jakarta projects
What makes HVAC, plant and machine noise control different in Jakarta?
Split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms. Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
Where should the budget go first on a Jakarta 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 Jakarta?
No. We manufacture in India and supply into Jakarta. 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 Jakarta site?
ships from: Palwal, Haryana, India, arrives at: Tanjung Priok, then a short road run into the city, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
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
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.
