School and classroom acoustics in Ludhiana
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. Large school and college campuses in concrete and tile, with halls carrying assembly and performance.
- 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 material, and what it actually does on a Ludhiana job
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.
Large school and college campuses in concrete and tile, with halls carrying assembly and performance.
Work reaching us from Ludhiana is mostly knitting and textile units, workshops, worker areas, offices, showrooms, schools, clinics.
- One to two days by road A dedicated truck from Palwal, with samples sent ahead so you can check the material before committing.
- Machine noise, all shift Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- Industry beside housing Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- 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 Ludhiana.
02 / The build-up
The build-up, layer by layer
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Ludhiana, agro processing and light engineering plant, with generator sets and machinery close to occupied buildings.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Ludhiana, auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Ludhiana, large school and college campuses in concrete and tile, with halls carrying assembly and performance.
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 Ludhiana 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 Ludhiana
- One to two days by road
A dedicated truck from Palwal, with samples sent ahead so you can check the material before committing.
- Machine noise, all shift
Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- Industry beside housing
Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- Hard halls, no intelligibility
Large sheds with steel and concrete surfaces make instructions and alarms hard to understand. Targeted absorption fixes that without touching the machines.
- Assembly and performance rooms
Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
- School and campus buildings
Large school and college campuses in concrete and tile, with halls carrying assembly and performance.
04 / Room by room
Where the money goes on a Ludhiana project
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. A dedicated truck from Palwal, with samples sent ahead so you can check the material before committing.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Wood wool acoustic panels, 20 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. Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- 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
- Acoustic carpet and rugs, Felt
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- PET felt acoustic panels, 4 to 24 mm
- Wood wool acoustic panels, 0.30
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate
The Ludhiana climate decides the material list
Ludhiana 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.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
06 / Worth knowing
What we watch go wrong on jobs like this
-
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.

05 / Getting it there
How material reaches a Ludhiana site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | one to two days |
| Dispatch | 2 to 4 working days |
| To site | one to two 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 three hundred and fifty kilometres. Full loads on a dedicated truck, smaller consignments on a shared vehicle.
Questions from Ludhiana projects
What makes school and classroom acoustics different in Ludhiana?
Large school and college campuses in concrete and tile, with halls carrying assembly and performance. Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
Where should the budget go first on a Ludhiana 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 Ludhiana?
No. We manufacture in India and supply into Ludhiana. 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 Ludhiana site?
made at: Our own plant, Palwal, Haryana, reaches site in: one to two 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
Drawings in, BOQ and a delivered date out
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
