For projects in Siliguri
School and classroom acoustics in Siliguri
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet. Long established schools and colleges in masonry with high ceilings and very large class sizes.
- Classroom RT
- A number, set against room volume, achieved mostly at the ceiling.
- Corridor spill
- Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
- Halls and gyms
- Dual use rooms carrying speech, music and sport, where durability decides the product.

01 / What it is
The product, described honestly, for a Siliguri brief
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet.
Long established schools and colleges in masonry with high ceilings and very large class sizes.
Work reaching us from Siliguri is mostly hotels and resorts, restaurants, hospitals, schools, offices, banquet halls.
- 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.
- Classroom RT A number, set against room volume, achieved mostly at the ceiling.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for school acoustics are on the main product page. This page covers what that means for a project in Siliguri.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Siliguri, 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.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Siliguri, auditoria, community halls and pandal spaces carry amplified speech and music at high level.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
-
Layer 3
Acoustic panels
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. In Siliguri, long established schools and colleges in masonry with high ceilings and very large class sizes.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
For a Siliguri practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

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.
- Assembly and performance rooms
Auditoria, community halls and pandal spaces carry amplified speech and music at high level.
- School and campus buildings
Long established schools and colleges in masonry with high ceilings and very large class sizes.
04 / Room by room
Space by space, for Siliguri briefs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. 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.
- Wood wool acoustic panels, 1200 x 600 mm
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. 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.
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Corridor noise and the next room generate the complaints. Door and wall detailing does that work, not the panel in the room.
- Wood wool acoustic panels, 400 kg per cubic metre
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic carpet and rugs, 64 sq ft per pack
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.
04 / Conditions
Why the climate in Siliguri changes the material, not the target
Siliguri is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is 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 failure we design against here is mould, sagging fabric finishes and swelling in timber.
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.
06 / Worth knowing
Where this kind of project usually fails
-
Panels at child height where they get damaged
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating one classroom and leaving the corridor
Small on the drawing, expensive on site, and almost always found after handover.
-
Choosing a product that cannot take a football
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.

Treating it as a generic 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.
05 / Getting it there
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 |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
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.
Questions from Siliguri projects
What makes school and classroom acoustics different in Siliguri?
Long established schools and colleges in masonry with high ceilings and very large class sizes. 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.
Where should the budget go first on a Siliguri project?
Classroom RT. A number, set against room volume, achieved mostly at the ceiling. Corridor spill. Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
Do you have an office or installation team in Siliguri?
No. We manufacture in India and supply into Siliguri. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Siliguri site?
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 goes wrong most often on this kind of project?
Panels at child height where they get damaged. Treating one classroom and leaving the corridor.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
Next step
Send a plan and a section, get a real build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
