Acoustic panels in Johannesburg
We manufacture 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.
- Plain PET felt
- 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
- Printed felt
- 1800 x 900 mm, image printed into the felt rather than onto a facing
- Grooved panels
- Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Test standard
- ASTM C423
- Lead time
- 4 to 7 working days standard
- Minimum order
- From 10 panels
- ASTM C423
- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
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 Johannesburg
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look.
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.
- Wall array Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
- Ceiling first In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
- Mixed finish Plain felt where it is out of eye line, printed or grooved where it is seen.
- What it will not do Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our acoustic panel range are on the main product page. This page covers what that means for a project in Johannesburg.

02 / Specification sheet
Published specification, identical wherever we ship it
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.
- EchoCore 151500 GSM. General commercial
- EchoPro 181800 GSM. Rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
03 / Local conditions
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.
- School and campus buildings
Classrooms are hard walled with high ceilings and large class sizes, and school halls double as assembly and performance spaces.
- The studio and content scene
A strong music and production culture works out of converted commercial and residential rooms with no isolation plan.
If you are specifying for a Johannesburg project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate and 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.
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 / Logistics
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 | Palletised flat and film wrapped. Printed panels interleaved and corner protected. |
| Lead time | 4 to 7 working days standard. Printed and grooved take longer. |
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.
200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load.
| Trial order | 200 panels, 6,400 sq ft, mixed thickness, GSM and colour |
|---|---|
| Recommended | Full container |
A panel is 1220 x 2440 mm, which is 32 sq ft.
06 / Read this first
The things worth knowing before you place the order
-
The wrong product for the problem
Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant. We would rather calculate the area than sell the wall.
-
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.

How it looks once it is installed
Johannesburg: questions we are actually asked
Are these 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 decides the specification for a Johannesburg project?
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.
When would material land on a Johannesburg site?
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 acoustic panels for?
Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant. We would rather calculate the area than sell the wall.
What is the minimum order and how is it packed?
200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped. Printed panels interleaved and corner protected.
