PET felt acoustic panels in South Africa
We manufacture PET felt acoustic panels 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.

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 / The product
What this is, and what it changes in a South Africa room
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. It absorbs mid and high frequency energy and finishes as the visible surface, so it is both the acoustic layer and the finish.
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.
- Direct to wall Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
- On a 25 to 50 mm air gap The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
- Over a porous backing Panel over mineral or PET backing where the room needs genuine low mid control.
- What it will not do It absorbs. It does not block.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for PET felt panels are on the main product page. This page covers what that means for a project in South Africa.
02 / The numbers
One specification sheet, the same in every market
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.
- EchoCore 151500 GSM. Offices, classrooms, general commercial
- EchoPro 181800 GSM. Studios, auditoria, rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

On a South Africa job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
What decides the build-up in South Africa
- 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.
- School and campus buildings
Classrooms are hard walled with high ceilings and large class sizes, and school halls double as assembly and performance spaces.
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 / Conditions
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.
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 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 | Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote. |
| Lead time | 4 to 7 working days for standard colours and thicknesses. Grooved and custom colours take longer, and we say so before you order. |
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.
200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use.
| Trial order | 200 panels, 6,400 sq ft, mixed thickness, GSM and colour |
|---|---|
| Recommended | Full container, for the best price per panel and the lowest freight per panel |
A panel is 1220 x 2440 mm, which is 32 sq ft.
06 / Before you buy
What we will tell you that a reseller will not
-
The wrong product for the problem
It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.
-
Local approvals that nobody actually holds
We hold no South Africa certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
South Africa: questions we are actually asked
Do you manufacture PET felt acoustic panels in South Africa?
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.
Why would a South Africa build-up differ from anywhere else?
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.
How does the South Africa climate affect this product?
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.
How quickly can material reach a site in South Africa?
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.
Where do PET felt acoustic panels fail to help?
It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.
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, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container, for the best price per panel and the lowest freight per panel. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.

Drawings in, BOQ and a delivered date out
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.
