SoundBlanket mass loaded vinyl in South Africa
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into South Africa. Made at our own plant in India and shipped into Durban, which is one of the better served routes from western India, then road inland.

We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / The material
What you are buying, and what it fixes in South Africa
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 South Africa is mostly offices and corporate parks, generator and plant enclosures, retail, hotels, schools, hospitals.
Brick and concrete construction with hard floors. Townhouse and cluster developments share walls that were built for structure, not for separation.
- 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 South Africa.
02 / The numbers
Published specification, identical wherever we ship it
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- 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 |

Where a consultant is already engaged on a South Africa 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 South Africa do to the specification
- Generators are everywhere
Standby generation runs regularly and sits close to occupied space and neighbours. Enclosure and mass, not absorption, is what solves it.
- A mature specification culture
Consultants are involved and targets are written down. Send us the specification and we will say where our material sits against it.
- Durban is well served
Frequent sailings from western India keep this route practical for container quantities and repeat orders.
- Brick and concrete construction
Walls carry mass, so the usual problems are hard live interiors and plant noise rather than speech through a wall.
- The housing stock
Brick and concrete construction with hard floors. Townhouse and cluster developments share walls that were built for structure, not for separation.
- The studio and content scene
A strong music and production culture works out of converted commercial and residential rooms with no isolation plan.
Architects working in South Africa 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
Why the climate in South Africa changes the material, not the target
South Africa is hot summers, mild winters and a distinct wet season, and that narrows the sensible material list before acoustics is even discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The risk we design against here is wet-season humidity behind linings.
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
What the route into South Africa actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Durban, then road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Durban |
| 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 Durban, then road inland. 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.

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.
-
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 South Africa 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.
South Africa: questions we are actually asked
Are these soundBlanket mass loaded vinyl made in South Africa?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into South Africa as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Durban, which is one of the better served routes from western India, then road inland. You buy at factory prices with one consistent batch across the order.
What decides the specification for a South Africa project?
Standby generation runs regularly and sits close to occupied space and neighbours. Enclosure and mass, not absorption, is what solves it. Consultants are involved and targets are written down. Send us the specification and we will say where our material sits against it. Those two things move the build-up far more than the panel figure does.
Will this material last in the South Africa climate?
South Africa is hot summers, mild winters and a distinct wet season. PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH. The failure we design against here is wet-season humidity behind linings.
When would material land on a South Africa site?
ships from: Palwal, Haryana, India, arrives at: Durban, then road inland, 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.
What is the minimum order and how is it packed?
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.
Next step
Send a plan and a section, get a real 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.
