Manufactured in India, supplied in Siliguri
Acoustic foam and BassBloc in Siliguri
We manufacture acoustic foam and BassBloc 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.

- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
- Test reports sent on request, not just quoted
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 material, and what it actually does on a Siliguri job
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing.
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.
- Corner loading Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
- First reflection points Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
- Behind a fabric frame Where the room has to look finished, absorber inside a frame rather than foam on show.
- What it will not do Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for acoustic foam and bass traps are on the main product page. This page covers what that means for a project in Siliguri.

The published figures, unchanged by location
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.

On a Siliguri job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

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.
- The housing stock
Older masonry buildings and newer RC frame apartments with hard floors, in very dense neighbourhoods with heavy monsoon damp.
- 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
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.
For a Siliguri interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
Getting it to Siliguri, with real dates
| 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 | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 4 to 7 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.
By road from Palwal, roughly fifteen hundred kilometres, normally three to four days on a dedicated truck.
200 sq ft for acoustic foam, 300 sq ft for BassBloc, 10 pieces for bass traps.
| Acoustic foam | 200 sq ft, about 19 sq m |
|---|---|
| BassBloc | 300 sq ft, about 28 sq m |
| Bass traps | 10 pieces |
A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels.

The things worth knowing before you place the order
-
The wrong product for the problem
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
-
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 Siliguri 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.

The material in real interiors
Siliguri: questions we are actually asked
Where are the acoustic foam and BassBloc you supply to Siliguri actually made?
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 changes the specification on a Siliguri job?
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.
What is the delivery time into 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 quantity do we have to order, and in what packaging?
