Manufactured in India, supplied in Hosur
PET felt acoustic panels in Hosur
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Hosur. Hosur is a manufacturing town on the edge of Bengaluru, and most of what we supply goes into new plants and the offices attached to them.

01 / Start here
What this material is and where it earns its place in Hosur
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 Hosur is mostly electronics and automotive plants, test and QC rooms, offices, canteens, training rooms, hostels.
RC frame houses and apartments with hard floors, built for heat and humidity with open plan layouts that carry sound room to room.
- 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 Hosur.
02 / Specification sheet
One specification sheet, the same in every market
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- 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

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 / In this market
What we see driving Hosur briefs
- New plants, decisions still open
On a greenfield build the enclosure and the partition can be designed in, which costs a fraction of fixing it after commissioning.
- Test and clean areas
QC and measurement rooms need a low background before any result means anything. That is isolation with a written target.
- Canteens and training rooms
Large hard rooms where hundreds of people eat or listen. Ceiling absorption does almost all of the work.
- Four to five days by road
A dedicated truck from Palwal, with samples sent ahead so the finish is approved before the order.
- School and campus buildings
Very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
If you are specifying for a Hosur project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Conditions
Why the climate in Hosur changes the material, not the target
Hosur is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The risk we design against here is mould, sagging fabric finishes and swelling in timber.
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 / Getting it there
How material reaches a Hosur site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four to five days |
| Dispatch | 2 to 4 working days |
| To site | four to five days |
| 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 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly two thousand two hundred kilometres, normally four to five days on a dedicated truck.
From 10 panels for 9 mm EchoCore 15. Other grades and thicknesses carry their own minimum.
| 9 mm EchoCore 15, 1500 GSM | 10 panels, 320 sq ft |
|---|---|
| 9 mm EchoPro 18, 1800 GSM | 50 panels, 1,600 sq ft |
| 9 mm EchoMax 22, 2200 GSM | 100 panels, 3,200 sq ft |
| 12 mm, 2400 GSM | 30 panels, 960 sq ft |
| 18 mm, 3000 GSM | 50 panels, 1,600 sq ft |
| 24 mm, 3600 GSM | 50 panels, 1,600 sq ft |
A panel is 1220 x 2440 mm, which is 32 sq ft.
06 / Before you buy
The things worth knowing before you place the order
-
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.
-
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 Hosur certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Hosur: questions we are actually asked
Where are the PET felt acoustic panels you supply to Hosur actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Hosur as the manufacturer rather than through a dealer. Hosur is a manufacturing town on the edge of Bengaluru, and most of what we supply goes into new plants and the offices attached to them. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Hosur project?
On a greenfield build the enclosure and the partition can be designed in, which costs a fraction of fixing it after commissioning. QC and measurement rooms need a low background before any result means anything. That is isolation with a written target. Those two things move the build-up far more than the panel figure does.
How does the Hosur climate affect this product?
Hosur is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.
What is the delivery time into Hosur?
made at: Our own plant, Palwal, Haryana, reaches site in: four to five days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
What will PET felt acoustic panels not do?
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 quantity do we have to order, and in what packaging?
From 10 panels for 9 mm EchoCore 15. Other grades and thicknesses carry their own minimum. 9 mm EchoCore 15, 1500 GSM, 10 panels, 320 sq ft. 9 mm EchoPro 18, 1800 GSM, 50 panels, 1,600 sq ft. 9 mm EchoMax 22, 2200 GSM, 100 panels, 3,200 sq ft. 12 mm, 2400 GSM, 30 panels, 960 sq ft. 18 mm, 3000 GSM, 50 panels, 1,600 sq ft. 24 mm, 3600 GSM, 50 panels, 1,600 sq ft.
