Manufactured in India, supplied in Siliguri
Acoustic panels in Siliguri
We manufacture acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Siliguri. Siliguri is the gateway to the Northeast and the hills, so a lot of what we ship here is onward bound to hotels and institutions beyond the city.

- 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

- 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 / The product
What this is, and what it changes in a Siliguri room
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 Siliguri is mostly hotels and resorts, restaurants, hospitals, schools, offices, banquet halls.
Older masonry buildings and newer RC frame apartments with hard floors, in very dense neighbourhoods with heavy monsoon damp.
- 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 Siliguri.

02 / Data sheet
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. General commercial
- EchoPro 181800 GSM. Rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces
| 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 |
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
03 / Local conditions
What decides the build-up in Siliguri
- Humidity decides the material
PET felt does not absorb moisture, shed fibre or feed mould. In a damp climate that is the difference between a finish that lasts and one that sags in two seasons.
- A distribution point, not just a destination
Material often moves onward to the hills and the Northeast. We pack for a second leg on rougher roads when you tell us that is happening.
- Hotel guest rooms
Corridor noise and the next room generate the complaints. Door and wall detailing does that work, not the panel in the room.
- Three to four days by road
A dedicated truck from Palwal, with the schedule confirmed before dispatch rather than estimated after.
- School and campus buildings
Long established schools and colleges in masonry with high ceilings and very large class sizes.
- 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.
If you are specifying for a Siliguri project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Conditions
The Siliguri climate decides the material list
Siliguri 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 / Route to site
Supply into Siliguri, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three to four days |
| Dispatch | 2 to 4 working days |
| To site | three to four 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 fifteen hundred kilometres, normally three to four 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 / Straight talk
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 Siliguri 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
Siliguri: questions we are actually asked
Is there a Siliguri factory behind this product?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Siliguri as the manufacturer rather than through a dealer. Siliguri is the gateway to the Northeast and the hills, so a lot of what we ship here is onward bound to hotels and institutions beyond the city. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Siliguri project?
PET felt does not absorb moisture, shed fibre or feed mould. In a damp climate that is the difference between a finish that lasts and one that sags in two seasons. Material often moves onward to the hills and the Northeast. We pack for a second leg on rougher roads when you tell us that is happening. Those two things move the build-up far more than the panel figure does.
Is this the right material for Siliguri conditions?
Siliguri 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 Siliguri?
made at: Our own plant, Palwal, Haryana, reaches site in: three to four 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.
What is the minimum order and how is it packed?
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.
