Manufactured in India, supplied in Tanzania
SoundBlanket mass loaded vinyl in Tanzania
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Tanzania. Made at our own plant in India and shipped into Dar es Salaam, a short and frequently served run from western India.

- One batch across the order, no blending between runs

We make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.
01 / The product
What this material is and where it earns its place in Tanzania
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 Tanzania is mostly hotels and lodges, offices, places of assembly, schools, hospitals, apartments.
Concrete and block construction with hard floors, in apartment blocks and compounds close to each other.
- 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 Tanzania.

The numbers, and they do not move by city
Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.

- 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

Where a consultant is already engaged on a Tanzania project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / In this market
What the buildings in Tanzania do to the specification
- A short sea leg from India
Western India to Dar es Salaam is one of the quicker runs we operate, which makes modest and repeat consignments practical.
- A gateway, not just a destination
Material often continues inland to neighbouring countries. Tell us if that is happening and we pack for the second leg.
- Lodges and hospitality
Hotel and lodge work where guest room isolation and function space acoustics are the two recurring briefs.
- Hot and humid on the coast
PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag quickly.
- The housing stock
Concrete and block construction with hard floors, in apartment blocks and compounds close to each other.
- The studio and content scene
A growing music and content sector working out of converted rooms with generator noise nearby.
For a Tanzania practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
Durability in Tanzania, before acoustics is discussed
Tanzania 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.
For a Tanzania interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
How material reaches a Tanzania site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Dar es Salaam, then road onward |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Dar es Salaam |
| 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 Dar es Salaam, then road onward to site or across the border. Air freight for samples.
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.

Where this goes wrong, said plainly
-
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.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.

Suppliers who imply a Tanzania 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.
Tanzania: questions we are actually asked
Where are the soundBlanket mass loaded vinyl you supply to Tanzania actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Tanzania as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Dar es Salaam, a short and frequently served run from western India. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Tanzania job?
Western India to Dar es Salaam is one of the quicker runs we operate, which makes modest and repeat consignments practical. Material often continues inland to neighbouring countries. Tell us if that is happening and we pack for the second leg. Those two things move the build-up far more than the panel figure does.
How does the Tanzania climate affect this product?
Tanzania 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 Tanzania site?
ships from: Palwal, Haryana, India, arrives at: Dar es Salaam, then road onward, 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.
What should you not buy soundBlanket mass loaded vinyl for?
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.
