Manufactured in India, supplied in Siliguri
Soundproofing materials in Siliguri
We manufacture soundproofing materials 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.

- 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 material is and where it earns its place in Siliguri
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
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.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in Siliguri.

02 / Data sheet
The numbers, and they do not move by city
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.

- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

Where a consultant is already engaged on a Siliguri project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / In this market
What the buildings in Siliguri do to the specification
- 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.
- Plant and HVAC
Split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
- The housing stock
Older masonry buildings and newer RC frame apartments with hard floors, in very dense neighbourhoods with heavy monsoon damp.
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
What the Siliguri climate rules in and rules out
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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Supply
What the route into Siliguri actually looks like
| 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 | Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.
06 / Straight talk
What we will tell you that a reseller will not
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
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 Siliguri
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.

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.
Why would a Siliguri build-up differ from anywhere else?
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.
Does Siliguri weather shorten the life of this material?
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 does an order actually travel to 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.
What should you not buy soundproofing materials for?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
What quantity do we have to order, and in what packaging?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.
