Soundproofing materials in South Africa
We manufacture soundproofing materials 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.

- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
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 / What it is
The product, described honestly, for a South Africa brief
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
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.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in South Africa.

02 / Specification
The numbers, and they do not move by city
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.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
03 / In this market
What we see driving South Africa briefs
- 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.
- Plant and HVAC
Split units and generator sets, with backup generation running often enough that its enclosure matters as much as the HVAC.
- The housing stock
Brick and concrete construction with hard floors. Townhouse and cluster developments share walls that were built for structure, not for separation.
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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Supply
How material reaches a South Africa site
| 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, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.
06 / Straight talk
Four honest warnings before you buy
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
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 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.

The product on finished jobs
South Africa: questions we are actually asked
Where are the soundproofing materials you supply to South Africa actually made?
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 soundproofing materials the wrong purchase?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
How is the order packed and what is the minimum?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.
