PET felt acoustic panels in Bangladesh
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Bangladesh. Made at our own plant in India and moved either by sea into Chattogram or overland through the land border, which is unusually direct for an export market.

- 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 / The product
What you are buying, and what it fixes in Bangladesh
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 Bangladesh is mostly garment and manufacturing units, generator and plant rooms, offices, hospitals, schools, hotels.
Reinforced concrete frames with brick infill and hard floors. Apartment blocks sit close together with shared walls and open light wells between them.
- 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 Bangladesh.
02 / Data sheet
One specification sheet, the same in every market
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- 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 Bangladesh project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / On the ground
The Bangladesh conditions that change the answer
- Dense, humid, monsoon climate
PET felt does not hold moisture or feed mould, which decides whether a ceiling survives more than a couple of seasons.
- Reachable by road
The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
- Garment units at scale
Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.
- Generators run constantly
Standby and continuous generation sits close to occupied space almost everywhere. That is mass and enclosure work, not panels.
- School and campus buildings
Classrooms are concrete and tile with very large class sizes, and street noise enters through open windows all day.
For a Bangladesh practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
Why the climate in Bangladesh changes the material, not the target
Bangladesh 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 / Getting it there
What the route into Bangladesh actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Chattogram by sea, or overland through the land border |
| Dispatch | 4 to 7 working days |
| Freight | Sea or land border |
| 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 Chattogram, or overland through the land border where that suits the programme better. 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 / Before you buy
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.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.

Suppliers who imply a Bangladesh 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.
Bangladesh: questions we are actually asked
Is there a Bangladesh 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 Bangladesh as the manufacturer rather than through a dealer. Made at our own plant in India and moved either by sea into Chattogram or overland through the land border, which is unusually direct for an export market. You buy at factory prices with one consistent batch across the order.
Why would a Bangladesh build-up differ from anywhere else?
The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit. Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second. Those two things move the build-up far more than the panel figure does.
Is this the right material for Bangladesh conditions?
Bangladesh 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.
What is the delivery time into Bangladesh?
ships from: Palwal, Haryana, India, arrives at: Chattogram by sea, or overland through the land border, 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.
