Wood wool acoustic panels in Bangladesh
We manufacture wood wool 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.

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 / The product
What this is, and what it changes in a Bangladesh room
Wood fibre bound into a rigid board with an open texture. Robust, paintable and used where the surface takes knocks, which is why it ends up in schools, sports halls and plant rooms.
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 fix Mechanically fixed to the soffit or wall. Durable and simple.
- On a cavity Mounted on battens with an air gap, which is where the low mid performance comes from.
- With a porous backing Board over mineral backing where the room needs more than the board alone gives.
- What it will not do At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wood wool 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
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.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings
| Panel size | 1200 x 600 mm |
|---|---|
| Thickness | 20 mm |
| Density | 400 kg per cubic metre |
| NRC | 0.30 |
| Test standards | ASTM C-423 and EN ISO 354 |
| Surface burning | Class A to ASTM E84 |
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
What we see driving Bangladesh briefs
- 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.
- Assembly and performance rooms
Community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
- School and campus buildings
Classrooms are concrete and tile with very large class sizes, and street noise enters through open windows all day.
Architects working in Bangladesh 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 / Durability
The Bangladesh climate decides the material list
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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Logistics
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, edge protected. Boards are rigid but the edges chip, so they travel protected. |
| Lead time | 4 to 7 working days for standard sizes. |
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.
The same 500 sq ft minimum applies on export.
| Any finish | 500 sq ft, about 46 sq m |
|---|
A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels.
06 / Read this first
Where this goes wrong, said plainly
-
The wrong product for the problem
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
-
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 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
Do you manufacture wood wool acoustic panels in Bangladesh?
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.
What changes the specification on a Bangladesh job?
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.
How quickly can material reach a site in 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 wood wool acoustic panels the wrong purchase?
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
What is the minimum order and how is it packed?
The same 500 sq ft minimum applies on export. Any finish, 500 sq ft, about 46 sq m. A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels. Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected.
