SoundBlanket mass loaded vinyl in Bangladesh
We manufacture soundBlanket mass loaded vinyl 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.

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 / Start here
The product, described honestly, for a Bangladesh brief
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. It is the barrier product, not an absorber, and it is the right answer when the problem is noise passing through a structure.
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.
- Wall, decoupled Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
- Floor, floating Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
- Duct and plant wrap Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
- What it will not do Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for SoundBlanket MLV 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.
- 2.5 mmSTC 30, 5.25 kg per sq m. Ducts, light partitions, retrofit where depth is tight
- 4 mmSTC 34, 8.4 kg per sq m. Party walls, floors, plant rooms, the common specification
- 6 mm12.6 kg per sq m. Machine enclosures and low frequency problems
| Density | 2100 kg per cubic metre |
|---|---|
| 2.5 mm | STC 30, 5.25 kg per sq m |
| 4 mm | STC 34, 8.4 kg per sq m |
| 6 mm | 12.6 kg per sq m, STC on request |
| Roll size | 5 x 1.2 m, 6 sq m per roll |
| Form | Limp sheet, cuts with a knife, seams lapped and sealed |
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
03 / Local conditions
The Bangladesh conditions that change the answer
- 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.
- 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.
- 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.
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 / Climate and durability
Durability in Bangladesh, before acoustics is discussed
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 / Supply
Getting it to Bangladesh, with real dates
| 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 | Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters. |
| Lead time | 4 to 7 working days. Full container quantities scheduled against the vessel. |
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 minimums apply on export as on domestic orders.
| 2.5 mm and 4 mm | 10 rolls, 60 sq m |
|---|---|
| 6 mm and other thicknesses | 10 tonnes per thickness |
A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm.
06 / Straight talk
Four honest warnings before you buy
-
The wrong product for the problem
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
-
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
Where are the soundBlanket mass loaded vinyl you supply to Bangladesh actually made?
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.
How does the Bangladesh climate affect this product?
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.
When would material land on a Bangladesh site?
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 soundBlanket mass loaded vinyl the wrong purchase?
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
Is there a minimum order, and how does it arrive?
The same minimums apply on export as on domestic orders. 2.5 mm and 4 mm, 10 rolls, 60 sq m. 6 mm and other thicknesses, 10 tonnes per thickness. A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm. Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters.
