Soundproofing materials in Johannesburg
We manufacture soundproofing materials at our own plant at Palwal in Haryana, India, and supply them into Johannesburg. Made at our own plant in India and shipped into Durban, then road up to the city, with the inland climb quoted as its own leg.

- 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Principle
- Mass, then decoupling, then cavity absorption, then sealing
- Test standards
- ASTM E90 for the barrier, ASTM C423 for the absorber

- 4 to 7 working days for stock items
- ASTM E90 for the barrier, ASTM C423 for the absorber
- Made at our own plant, Palwal, Haryana, 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 / Start here
What this is, and what it changes in a Johannesburg room
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 Johannesburg is mostly corporate office parks, generator enclosures, retail, hotels, schools, hospitals, studios.
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 Johannesburg.

02 / The numbers
One specification sheet, the same in every market
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- 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 the buildings in Johannesburg do to the specification
- Generator noise is routine
Standby plant runs often enough that it has to be treated as a permanent condition. Enclosure at the source is the only reliable answer.
- Office parks, not street frontage
Campus style buildings with large open floors and hard finishes. Speech carries a long way and the ceiling plane has to carry the room.
- The climb from Durban
The inland leg is long and it is real. We quote it separately so the programme is built on actual dates.
- Altitude and dry air
PET felt is stable in dry conditions and does not shed fibre, which suits sealed, conditioned buildings.
- 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.
For a Johannesburg practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Durability
Why the climate in Johannesburg changes the material, not the target
Johannesburg 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.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
05 / Route to site
How material reaches a Johannesburg site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Durban, then road up to Johannesburg |
| 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 up to Johannesburg. Air freight for samples and urgent quantities.
06 / Read this first
Where this goes wrong, said plainly
-
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.
-
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.
-
Local approvals that nobody actually holds
We hold no Johannesburg certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

The product on finished jobs
Johannesburg: questions we are actually asked
Where are the soundproofing materials you supply to Johannesburg actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Johannesburg as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Durban, then road up to the city, with the inland climb quoted as its own leg. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Johannesburg job?
Standby plant runs often enough that it has to be treated as a permanent condition. Enclosure at the source is the only reliable answer. Campus style buildings with large open floors and hard finishes. Speech carries a long way and the ceiling plane has to carry the room. Those two things move the build-up far more than the panel figure does.
Will this material last in the Johannesburg climate?
Johannesburg 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.
How does an order actually travel to Johannesburg?
ships from: Palwal, Haryana, India, arrives at: Durban, then road up to Johannesburg, 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.
Next step
Tell us the room, we will tell you the 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.
