- One batch across the order, no blending between runs
We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / What it is
The material, and what it actually does on a Bangkok job
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 Bangkok is mostly condo towers, hotels and lounges, offices, restaurants, clinics, studios.
Concrete frame with block infill and hard tile floors throughout. Condominium party walls and slabs pass impact noise directly.
- 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 Bangkok.
02 / Specification sheet
Published specification, identical wherever we ship it
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- 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 Bangkok project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / Local conditions
What we see driving Bangkok briefs
- Heat and humidity all year
Our PET felt does not hold moisture or feed mould, which matters where mineral products sag in a tropical climate.
- Concrete towers, live interiors
The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- Elevated rail and traffic
Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- Impact through slabs
Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix.
- School and campus buildings
Classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
For a Bangkok practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate and durability
What the Bangkok climate rules in and rules out
Bangkok 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.
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.
05 / Getting it there
What the route into Bangkok actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Laem Chabang, then a short road run into Bangkok |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Laem Chabang |
| 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 Laem Chabang, then a short road run into Bangkok. 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.
| 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 / Worth knowing
The things worth knowing before you place the order
-
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.
-
Local approvals that nobody actually holds
We hold no Bangkok certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Bangkok: questions we are actually asked
Is there a Bangkok factory behind this product?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Bangkok as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Laem Chabang, roughly two hours from the city by road. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Bangkok enquiry?
The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job. Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first. Those two things move the build-up far more than the panel figure does.
Will this material last in the Bangkok climate?
Bangkok 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 does an order actually travel to Bangkok?
ships from: Palwal, Haryana, India, arrives at: Laem Chabang, then a short road run into Bangkok, 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 will PET felt acoustic panels not do?
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.
What quantity do we have to order, and in what packaging?
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.
