Manufactured in India, supplied in Cape Town
SoundBlanket mass loaded vinyl in Cape Town
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Cape Town. Made at our own plant in India and shipped straight into Cape Town, so the container lands at the city rather than crossing the country by road.

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 material
What this material is and where it earns its place in Cape Town
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 Cape Town is mostly hotels and restaurants, heritage conversions, offices, apartments, schools, studios.
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 Cape Town.
02 / The numbers
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.
- 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 |
|---|---|

| 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 |
Where a consultant is already engaged on a Cape Town project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / Local conditions
The Cape Town conditions that change the answer
- Wind and coastal damp
PET felt does not absorb moisture or feed mould, which matters on exposed coastal elevations.
- The port is at the city
Direct sea into Cape Town avoids the long inland haul, which makes the landed cost and the date both easier to hold.
- Heritage fabric stays put
Older buildings in the city cannot be structurally altered. Work has to be internal, shallow and ideally reversible.
- Hospitality is the market
Hotels and restaurants where the room is part of what the guest is paying for, judged when it is completely full.
- 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.
For a Cape Town practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate and durability
What the Cape Town climate rules in and rules out
Cape Town 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.
For a Cape Town interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Getting it there
Supply into Cape Town, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Cape Town, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Cape Town |
| 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 direct into Cape Town, then a short road run to site. 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.

The things worth knowing before you place the order
-
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.

A claim of being local to Cape Town
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.
Cape Town: questions we are actually asked
Are these soundBlanket mass loaded vinyl made in Cape Town?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Cape Town as the manufacturer rather than through a dealer. Made at our own plant in India and shipped straight into Cape Town, so the container lands at the city rather than crossing the country by road. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Cape Town enquiry?
Direct sea into Cape Town avoids the long inland haul, which makes the landed cost and the date both easier to hold. Older buildings in the city cannot be structurally altered. Work has to be internal, shallow and ideally reversible. Those two things move the build-up far more than the panel figure does.
Will this material last in the Cape Town climate?
Cape Town 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.
What is the delivery time into Cape Town?
ships from: Palwal, Haryana, India, arrives at: Cape Town, then a short road run to site, 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.
How is the order packed and what is the minimum?
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.
