Manufactured in India, supplied in Dhaka
Acoustic foam and BassBloc in Dhaka
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Dhaka. Made at our own plant in India and moved by sea into Chattogram or overland through the land border, then road into the city.

- 1800 x 900 mm
- BassBloc thickness
- 20 mm
- BassBloc density
- 100 kg per cubic metre
- Effective range
- 100 to 500 Hz
- BassBloc NRC
- 0.85
- Lead time
- 4 to 7 working days
- Minimum order
- From 200 sq ft
- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
- Test reports sent on request, not just quoted
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 / The product
What you are buying, and what it fixes in Dhaka
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing.
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.
- Corner loading Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
- First reflection points Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
- Behind a fabric frame Where the room has to look finished, absorber inside a frame rather than foam on show.
- What it will not do Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for acoustic foam and bass traps are on the main product page. This page covers what that means for a project in Dhaka.
02 / Data 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.
- Foam wedge and pyramidLow density. Flutter and high frequency only
- BassBloc100 kg per cubic metre. Low mid absorption, control rooms, live rooms
| BassBloc size | 1800 x 900 mm |
|---|---|
| BassBloc thickness | 20 mm |
| BassBloc density | 100 kg per cubic metre |
| Effective range | 100 to 500 Hz |
| BassBloc NRC | 0.85 |
Where a consultant is already engaged on a Dhaka 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 Dhaka briefs
- 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.
- The housing stock
Reinforced concrete frames with brick infill and hard floors. Apartment blocks sit close together with shared walls and open light wells between them.
- The studio and content scene
Studios go into apartment rooms and commercial floors with neighbours on every side and generators running during outages.
If you are specifying for a Dhaka project, we can give you a section, a BOQ and the honest limits of each layer. 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.
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 / Logistics
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 | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 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.
Sea freight into Chattogram or overland through the land border, then road into Dhaka. Air freight for samples and urgent quantities.
The same minimums apply on export.
| Acoustic foam | 200 sq ft, about 19 sq m |
|---|---|
| BassBloc | 300 sq ft, about 28 sq m |
| Bass traps | 10 pieces |
A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels.
06 / Read this first
Where this goes wrong, said plainly
-
The wrong product for the problem
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
-
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.
-
A claim of being local to Dhaka
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.

The material in real interiors
Dhaka: questions we are actually asked
Is there a Dhaka 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 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 changes the specification on a Dhaka job?
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.
Is this the right material for Dhaka conditions?
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 does an order actually travel to 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.
Where do acoustic foam and BassBloc fail to help?
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
Is there a minimum order, and how does it arrive?
The same minimums apply on export. Acoustic foam, 200 sq ft, about 19 sq m. BassBloc, 300 sq ft, about 28 sq m. Bass traps, 10 pieces. A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels. Compressed and boxed for foam, palletised flat for BassBloc.

Tell us the room, we will tell you the build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
