School and classroom acoustics in Nepal
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. Classrooms are concrete and tile with large class sizes and street noise through open windows.
- 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 / The product
What this is, and what it changes in a Nepal room
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.
Classrooms are concrete and tile with large class sizes and street noise through open windows.
Work reaching us from Nepal is mostly hotels and guest houses, offices, hospitals, schools, assembly halls, houses.
- Reached entirely by road No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
- Rebuilt and reinforced structures A great deal of stock has been rebuilt or retrofitted for seismic performance. Movement joints must stay free and an acoustic layer must not stiffen across them.
- Hospitality in dense valleys Hotels and guest houses packed into tight streets where street noise reaches rooms through openings rather than walls.
- 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 Nepal.
02 / The build-up
The build-up, layer by layer
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Nepal, split units and generator sets, with generators close to occupied rooms during outages.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
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 Nepal, temples, function halls and conference rooms are hard volumes carrying amplified speech and music.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Nepal, classrooms are concrete and tile with large class sizes and street noise through open windows.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
For a Nepal 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 Nepal
- Reached entirely by road
No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
- Rebuilt and reinforced structures
A great deal of stock has been rebuilt or retrofitted for seismic performance. Movement joints must stay free and an acoustic layer must not stiffen across them.
- Hospitality in dense valleys
Hotels and guest houses packed into tight streets where street noise reaches rooms through openings rather than walls.
- Packing for mountain roads
The final leg is often on rough road. We brace and wrap for that rather than for a smooth port transfer.
- Assembly and performance rooms
Temples, function halls and conference rooms are hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are concrete and tile with large class sizes and street noise through open windows.
04 / Room by room
Where the money goes on a Nepal project
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. A great deal of stock has been rebuilt or retrofitted for seismic performance. Movement joints must stay free and an acoustic layer must not stiffen across them.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- 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
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Hotels and guest houses packed into tight streets where street noise reaches rooms through openings rather than walls.
- PET felt acoustic panels, 4 to 24 mm
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Durability
What the Nepal climate rules in and rules out
Nepal is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
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.

Where this kind of project usually fails
-
Panels at child height where they get damaged
This is the one that comes back as a second fit-out rather than a snag.
-
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
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
Treating it as a generic Nepal job
No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
05 / Logistics
Supply into Nepal, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Overland through the India border, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Road via the India border |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Overland by road through the India border, then on to site. No sea leg and no port handling.
Questions from Nepal projects
What makes school and classroom acoustics different in Nepal?
Classrooms are concrete and tile with large class sizes and street noise through open windows. No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
Where should the budget go first on a Nepal 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 Nepal?
No. We manufacture in India and supply into Nepal. 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 Nepal site?
ships from: Palwal, Haryana, India, arrives at: Overland through the India border, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. 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
Drawings in, BOQ and a delivered date out
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.
