Acoustic panels in Tiruchirappalli
We manufacture 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.
- 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
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 / What it is
The product, described honestly, for a Tiruchirappalli brief
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 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.
- 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 Tiruchirappalli.

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.
- EchoCore 151500 GSM. General commercial
- EchoPro 181800 GSM. Rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

Where a consultant is already engaged on a Tiruchirappalli project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / On the ground
The Tiruchirappalli conditions that change the answer
- 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.
- The studio and content scene
Studios go into basements, terrace rooms and back rooms with neighbours on every side and a generator somewhere in the lane. Isolating from the building has to come before treating the room.
For a Tiruchirappalli practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
Durability in Tiruchirappalli, before acoustics is discussed
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.
For a Tiruchirappalli interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Getting it there
Supply into Tiruchirappalli, start to site
| 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. Printed panels interleaved and corner protected. |
| Lead time | 4 to 7 working days standard. Printed and grooved take longer. |
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.
06 / Before you buy
What we will tell you that a reseller will not
-
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.
-
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.
-
A claim of being local to Tiruchirappalli
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.

The material in real interiors
Tiruchirappalli: questions we are actually asked
Where are the 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.
How does the Tiruchirappalli climate affect this product?
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 does an order actually travel to 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.
Where do acoustic panels fail to help?
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.
Is there a minimum order, and how does it arrive?
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. Palletised flat and film wrapped. Printed panels interleaved and corner protected.
