PET felt acoustic panels in Tiruchirappalli
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Tiruchirappalli. Tiruchirappalli combines heavy engineering with a large education sector, so our material goes into workshops and lecture halls in the same city.

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 / What it is
The material, and what it actually does on a Tiruchirappalli job
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 Tiruchirappalli is mostly heavy engineering plant, colleges and hostels, auditoriums, hospitals, offices, hotels.
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 Tiruchirappalli.
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 Tiruchirappalli job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / On the ground
What decides the build-up in Tiruchirappalli
- Heat and sealed rooms
Air conditioned rooms stay closed, so sound accumulates inside rather than escaping. Absorption has to be balanced, not maximised.
- Heavy engineering noise
Fabrication, presses and compressors are low frequency and travel through the structure. Enclosure and mass, not wall panels.
- Large teaching rooms
Lecture halls in concrete and tile defeat the speaker long before anyone calls the room echoey. Targeted absorption recovers it.
- Five days by road
A long run, confirmed before dispatch, with samples ahead of the order.
- School and campus buildings
Very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate and durability
What the Tiruchirappalli climate rules in and rules out
Tiruchirappalli 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.
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 / Supply
What the route into Tiruchirappalli actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five days |
| Dispatch | 2 to 4 working days |
| To site | 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 four hundred kilometres, normally 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.

Where this goes wrong, said plainly
-
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.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.

Suppliers who imply a Tiruchirappalli presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Tiruchirappalli: questions we are actually asked
Where are the PET felt acoustic panels you supply to Tiruchirappalli actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Tiruchirappalli as the manufacturer rather than through a dealer. Tiruchirappalli combines heavy engineering with a large education sector, so our material goes into workshops and lecture halls in the same city. You buy at factory prices with one consistent batch across the order.
Why would a Tiruchirappalli build-up differ from anywhere else?
Fabrication, presses and compressors are low frequency and travel through the structure. Enclosure and mass, not wall panels. Lecture halls in concrete and tile defeat the speaker long before anyone calls the room echoey. Targeted absorption recovers it. Those two things move the build-up far more than the panel figure does.
Is this the right material for Tiruchirappalli conditions?
Tiruchirappalli 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.
How quickly can material reach a site in Tiruchirappalli?
made at: Our own plant, Palwal, Haryana, reaches site in: 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.
How is the order packed and what is the minimum?
