Wood wool acoustic panels in Johannesburg
We manufacture wood wool acoustic panels 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.

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 Johannesburg
Wood fibre bound into a rigid board with an open texture. Robust, paintable and used where the surface takes knocks, which is why it ends up in schools, sports halls and plant rooms.
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.
- Direct fix Mechanically fixed to the soffit or wall. Durable and simple.
- On a cavity Mounted on battens with an air gap, which is where the low mid performance comes from.
- With a porous backing Board over mineral backing where the room needs more than the board alone gives.
- What it will not do At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wood wool panels are on the main product page. This page covers what that means for a project in Johannesburg.
02 / Specification
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.

- Painted20 mm. Classrooms, halls, visible ceilings

On a Johannesburg job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / In this market
What we see driving Johannesburg briefs
- 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.
- Assembly and performance rooms
Church buildings and community halls are large hard rooms carrying amplified music and speech at high level.
- School and campus buildings
Classrooms are hard walled with high ceilings and large class sizes, and school halls double as assembly and performance spaces.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Conditions
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.
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 / Route to site
What the route into Johannesburg actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Durban, then road up to Johannesburg |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Durban |
| Packing | Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected. |
| Lead time | 4 to 7 working days for standard sizes. |
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.
The same 500 sq ft minimum applies on export.
| Any finish | 500 sq ft, about 46 sq m |
|---|
A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels.
06 / Worth knowing
What we will tell you that a reseller will not
-
The wrong product for the problem
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
-
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.
Johannesburg: questions we are actually asked
Are these wood wool acoustic panels made in Johannesburg?
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.
How does the Johannesburg climate affect this product?
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 quickly can material reach a site in 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.
What should you not buy wood wool acoustic panels for?
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
What is the minimum order and how is it packed?
The same 500 sq ft minimum applies on export. Any finish, 500 sq ft, about 46 sq m. A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels. Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected.
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.
