01 / Start here

What this material is and where it earns its place in Indonesia

A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. It absorbs mid and high frequency energy and finishes as the visible surface, so it is both the acoustic layer and the finish.

Work reaching us from Indonesia is mostly offices and towers, hotels and resorts, manufacturing plants, hospitals, schools, studios.

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.

  • Direct to wall Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
  • On a 25 to 50 mm air gap The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
  • Over a porous backing Panel over mineral or PET backing where the room needs genuine low mid control.
  • What it will not do It absorbs. It does not block.

Full specification

Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for PET felt panels are on the main product page. This page covers what that means for a project in Indonesia.

02 / Specification sheet

The numbers, and they do not move by city

These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.

  • EchoCore 151500 GSM. Offices, classrooms, general commercial
  • EchoPro 181800 GSM. Studios, auditoria, rooms with a written RT target
  • EchoMax 222200 GSM. High occupancy and high level spaces

Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.

03 / On the ground

What the buildings in Indonesia do to the specification

  • 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.

  • 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.

  • 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.

  • School and campus buildings

    Classrooms are hard, naturally ventilated and open to corridor and street noise, so absorption alone will not fix intelligibility.

If you are specifying for a Indonesia project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.

04 / Climate and durability

Why the climate in Indonesia changes the material, not the target

Indonesia is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even 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 risk we design against here is mould, sagging fabric finishes and swelling in timber.

For a Indonesia interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.

05 / Supply

What the route into Indonesia actually looks like

Supply into Indonesia
Ships fromPalwal, Haryana, India
Arrives atTanjung Priok, then road or onward by sea
Dispatch4 to 7 working days
FreightSea via Tanjung Priok
PackingPalletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
Lead time4 to 7 working days for standard colours and thicknesses. Grooved and custom colours take longer, and we say so before you order.

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.

200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use.

Minimum order, pet felt acoustic panels
Trial order200 panels, 6,400 sq ft, mixed thickness, GSM and colour
RecommendedFull container, for the best price per panel and the lowest freight per panel

A panel is 1220 x 2440 mm, which is 32 sq ft.

What we will tell you that a reseller will not

  • The wrong product for the problem

    It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.

  • Square footage quoted before the room is understood

    Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.

  • Local approvals that nobody actually holds

    We hold no Indonesia certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

FAQ

Indonesia: questions we are actually asked

Where are the PET felt acoustic panels you supply to Indonesia actually made?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Indonesia as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Tanjung Priok, then road or inter-island onward, with the second leg quoted when it applies. You buy at factory prices with one consistent batch across the order.

Why would a Indonesia build-up differ from anywhere else?

Material often continues by road or inter-island ferry after the port. Tell us and we brace and wrap for the second journey. PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons. Those two things move the build-up far more than the panel figure does.

Does Indonesia weather shorten the life of this material?

Indonesia is warm and humid through most of the year, with a long wet season. 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.

How quickly can material reach a site in Indonesia?

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.

When are PET felt acoustic panels the wrong purchase?

It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.

Is there a minimum order, and how does it arrive?

200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container, for the best price per panel and the lowest freight per panel. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
