Home theatre soundproofing and acoustics in Indonesia
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is. Concrete frame with block infill in cities, timber and light construction outside them. Apartment stock shares walls and slabs that were never detailed for two households.
- Containment
- Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
- Low frequency inside
- Corner absorption with depth, before any surface treatment.
- Reflections
- Side wall and ceiling first reflection points at the seating position.

The material, and what it actually does on a Indonesia job
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is.
Concrete frame with block infill in cities, timber and light construction outside them. Apartment stock shares walls and slabs that were never detailed for two households.
Work reaching us from Indonesia is mostly offices and towers, hotels and resorts, manufacturing plants, hospitals, schools, studios.
- An onward leg is normal Material often continues by road or inter-island ferry after the port. Tell us and we brace and wrap for the second journey.
- Tropical humidity all year PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- Dense cities, constant traffic Street noise reaches rooms through openings and glazing long before it comes through the wall. Fix the weakest path first.
- Containment Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for home theatre soundproofing are on the main product page. This page covers what that means for a project in Indonesia.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
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 Indonesia, split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
Layer 2
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Indonesia, places of worship, function halls and community buildings are large hard rooms carrying amplified speech and music.
Track with a seal. Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Indonesia, classrooms are hard, naturally ventilated and open to corridor and street noise, so absorption alone will not fix intelligibility.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
Architects working in Indonesia usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.

What decides the build-up in Indonesia
- An onward leg is normal
Material often continues by road or inter-island ferry after the port. Tell us and we brace and wrap for the second journey.
- Tropical humidity all year
PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- Dense cities, constant traffic
Street noise reaches rooms through openings and glazing long before it comes through the wall. Fix the weakest path first.
- Manufacturing at scale
Plant noise where enclosure and mass do the work, and measurement rooms that need a genuinely low background.
- The housing stock
Concrete frame with block infill in cities, timber and light construction outside them. Apartment stock shares walls and slabs that were never detailed for two households.

Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Material often continues by road or inter-island ferry after the port. Tell us and we brace and wrap for the second journey.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic foam and BassBloc, 20 mm
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
-
Low frequency inside
Corner absorption with depth, before any surface treatment. PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic foam and BassBloc, 100 kg per cubic metre
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
-
Reflections
Side wall and ceiling first reflection points at the seating position. Street noise reaches rooms through openings and glazing long before it comes through the wall. Fix the weakest path first.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic foam and BassBloc, 100 to 500 Hz
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
The Indonesia climate decides the material list
Indonesia 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.
Where a consultant is already engaged on a Indonesia project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

The six errors that cost the most
-
Foam on the walls as a soundproofing measure
It sounds like a small detail until the room is finished and the complaint arrives.
-
A standard door on a room built to hold bass
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating before the room is sealed
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.
-
Treating it as a generic Indonesia job
Material often continues by road or inter-island ferry after the port. Tell us and we brace and wrap for the second journey.
05 / Logistics
What the route into Indonesia actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Tanjung Priok, then road or onward by sea |
| 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 road or inter-island onward. Air freight for samples and urgent quantities.
Questions from Indonesia projects
What makes home theatre soundproofing and acoustics different in Indonesia?
Concrete frame with block infill in cities, timber and light construction outside them. Apartment stock shares walls and slabs that were never detailed for two households. Material often continues by road or inter-island ferry after the port. Tell us and we brace and wrap for the second journey.
Where should the budget go first on a Indonesia project?
Containment. Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Low frequency inside. Corner absorption with depth, before any surface treatment.
Do you have an office or installation team in Indonesia?
No. We manufacture in India and supply into Indonesia. 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 Indonesia site?
ships from: Palwal, Haryana, India, arrives at: Tanjung Priok, then road or onward by sea, 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?
Foam on the walls as a soundproofing measure. A standard door on a room built to hold bass.
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.
