Office acoustics and soundproofing in Jakarta
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. Split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

01 / The material
What this is, and what it changes in a Jakarta room
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
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.
- The port is in the city Tanjung Priok is close, which keeps the road leg short and the landed cost predictable.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in Jakarta.

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 Jakarta, split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 2
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Jakarta, places of worship, function halls and community buildings are large hard rooms carrying amplified speech and music.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
-
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 Jakarta, classrooms are hard, naturally ventilated and open to corridor and street noise, so absorption alone will not fix intelligibility.
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 / In this market
What decides the build-up in Jakarta
- 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.
- The port is in the city
Tanjung Priok is close, which keeps the road leg short and the landed cost predictable.
- Standby generation
Power backup sits close to occupied space in most commercial buildings and runs often enough to matter.
- Plant and HVAC
Split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.

Room by room, on a typical Jakarta job
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Traffic and construction reach rooms through glazing and openings long before they come through a wall. Fix the weakest path first.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. The structure blocks well. The problem is tile, glass and stone inside making the room ring.
- Ceiling baffles and clouds, 9 to 24 mm
- PET felt acoustic panels, 4 to 24 mm
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. Tanjung Priok is close, which keeps the road leg short and the landed cost predictable.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- SoundBlanket mass loaded vinyl, 5 x 1.2 m, 6 sq m per roll
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate
Why the climate in Jakarta changes the material, not the target
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.

The six errors that cost the most
-
Lining every wall while leaving the ceiling bare
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating a privacy problem with absorption
Privacy is a transmission problem. Absorption makes the room sound nicer and does not stop anyone hearing through the wall.
-
Glass cabins specified without a door and head detail
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
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 / Getting it there
How material reaches 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 |
| 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 office acoustics and soundproofing 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?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
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?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
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.
