Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.
01 / Start here
What you are buying, and what it fixes in Bali
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 Bali is mostly resorts and villas, beach clubs and restaurants, spas, offices, guest rooms.
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 Bali.
02 / Specification
One specification sheet, the same in every market
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

Where a consultant is already engaged on a Bali project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / Local conditions
The Bali conditions that change the answer
- Humidity and salt destroy the wrong material
PET felt does not absorb moisture, rot or feed mould. Mineral products sag here within a single season.
- Buildings that are only partly enclosed
Open pavilions and sliding walls mean there is often no envelope to isolate. The honest answer is treating what is there and telling you what cannot be fixed.
- Beach clubs and neighbours
Late trading venues beside villas and other resorts, where containment of low frequency is what keeps the operation on good terms.
- An onward leg to the island
Material arrives and then continues by road or ferry. Tell us and we pack for the second journey.
- School and campus buildings
Classrooms are hard, naturally ventilated and open to corridor and street noise, so absorption alone will not fix intelligibility.
Architects working in Bali usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Climate and durability
Why the climate in Bali changes the material, not the target
Bali 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.
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.
05 / Supply
How material reaches a Bali site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Surabaya or Benoa, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Surabaya or Benoa |
| Packing | Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote. |
| Lead time | 4 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 Surabaya or Benoa, then road or ferry onward to site. Air freight for samples.
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.
06 / Straight talk
Where this goes wrong, said plainly
-
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.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.

Suppliers who imply a Bali presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Bali: questions we are actually asked
Are these PET felt acoustic panels made in Bali?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Bali as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Surabaya or Benoa, then road or inter-island onward to site. You buy at factory prices with one consistent batch across the order.
Why would a Bali build-up differ from anywhere else?
Open pavilions and sliding walls mean there is often no envelope to isolate. The honest answer is treating what is there and telling you what cannot be fixed. Late trading venues beside villas and other resorts, where containment of low frequency is what keeps the operation on good terms. Those two things move the build-up far more than the panel figure does.
Is this the right material for Bali conditions?
Bali 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.
When would material land on a Bali site?
ships from: Palwal, Haryana, India, arrives at: Surabaya or Benoa, then road to site, 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.
How is the order packed and what is the minimum?
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.
