This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / What it is
The product, described honestly, for a Dhaka brief
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 Dhaka is mostly apartments, offices, garment unit admin blocks, hospitals, schools, hotels, studios.
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 Dhaka.
02 / Specification
One specification sheet, the same in every market
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

If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
03 / On the ground
What the buildings in Dhaka do to the specification
- Noise arrives from outside
Traffic, generators and construction reach the room through windows and gaps long before they come through the wall. Treat the weakest path, not the biggest surface.
- Generators in every gap
Standby generation sits in courtyards and alleys next to bedrooms and offices. Enclosure at the source is the only thing that works.
- Buildings against buildings
There is often no gap at all between structures, so sound moves between buildings as well as within them.
- A short route from the plant
Sea into Chattogram or overland through the border, which keeps lead times short and consignments flexible.
- 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 Dhaka practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Conditions
The Dhaka climate decides the material list
Dhaka 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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Route to site
What the route into Dhaka actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Chattogram or the land border, then road into Dhaka |
| 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, then road into Dhaka. 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.
-
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 Dhaka 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.
Dhaka: questions we are actually asked
Are these PET felt acoustic panels made in Dhaka?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Dhaka as the manufacturer rather than through a dealer. Made at our own plant in India and moved by sea into Chattogram or overland through the land border, then road into the city. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Dhaka project?
Traffic, generators and construction reach the room through windows and gaps long before they come through the wall. Treat the weakest path, not the biggest surface. Standby generation sits in courtyards and alleys next to bedrooms and offices. Enclosure at the source is the only thing that works. Those two things move the build-up far more than the panel figure does.
How does the Dhaka climate affect this product?
Dhaka 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 Dhaka?
ships from: Palwal, Haryana, India, arrives at: Chattogram or the land border, then road into Dhaka, 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.
