School and classroom acoustics in Chandigarh
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. Well established school and university campuses with lecture halls, libraries and hostels in concrete and tile.
- 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 Chandigarh 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.
Well established school and university campuses with lecture halls, libraries and hostels in concrete and tile.
Work reaching us from Chandigarh is mostly institutional and government buildings, colleges, offices, auditoriums, clinics, hotels.
- Concrete is the finish Exposed board-marked concrete cannot be covered without losing the building. Absorption has to go on the ceiling plane or high on the wall, discreetly.
- Generous volumes Rooms here are larger and taller than equivalents elsewhere, which lengthens reverberation and defeats speech.
- Planned, low rise, quiet outside External noise is rarely the issue. What comes to us is the room itself and noise between rooms.
- 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 Chandigarh.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Chandigarh, 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.
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 Chandigarh, 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.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Chandigarh, well established school and university campuses with lecture halls, libraries and hostels in concrete and tile.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
We would rather argue about the build-up at design stage than on site. See how we support architects.

What decides the build-up in Chandigarh
- Concrete is the finish
Exposed board-marked concrete cannot be covered without losing the building. Absorption has to go on the ceiling plane or high on the wall, discreetly.
- Generous volumes
Rooms here are larger and taller than equivalents elsewhere, which lengthens reverberation and defeats speech.
- Planned, low rise, quiet outside
External noise is rarely the issue. What comes to us is the room itself and noise between rooms.
- Next day from the plant
A few hours by road, so samples and replacements are straightforward.
- 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
Well established school and university campuses with lecture halls, libraries and hostels in concrete and tile.

Room by room, on a typical Chandigarh job
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Exposed board-marked concrete cannot be covered without losing the building. Absorption has to go on the ceiling plane or high on the wall, discreetly.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- 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. Rooms here are larger and taller than equivalents elsewhere, which lengthens reverberation and defeats speech.
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Acoustic carpet and rugs, Felt
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. External noise is rarely the issue. What comes to us is the room itself and noise between rooms.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic panels, ASTM C423
- Acoustic carpet and rugs, 64 sq ft per pack
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 / Conditions
What the Chandigarh climate rules in and rules out
Chandigarh 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.
On a Chandigarh job with a consultant involved, our part is material that matches the submitted data. See 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
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Treating it as a generic Chandigarh job
Exposed board-marked concrete cannot be covered without losing the building. Absorption has to go on the ceiling plane or high on the wall, discreetly.
05 / Route to site
Supply into Chandigarh, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | a day |
| Dispatch | 2 to 4 working days |
| To site | a day |
| 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 kilometres, normally next day on a dedicated truck.
Questions from Chandigarh projects
What makes school and classroom acoustics different in Chandigarh?
Well established school and university campuses with lecture halls, libraries and hostels in concrete and tile. Exposed board-marked concrete cannot be covered without losing the building. Absorption has to go on the ceiling plane or high on the wall, discreetly.
Where should the budget go first on a Chandigarh 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 Chandigarh?
No. We manufacture in India and supply into Chandigarh. 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 Chandigarh site?
made at: Our own plant, Palwal, Haryana, reaches site in: a day, 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
Tell us the room, we will tell you the build-up
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.
