School and classroom acoustics in Paris
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. School buildings are hard surfaced with high ceilings, and canteens are consistently the loudest rooms.
- 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 Paris 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.
School buildings are hard surfaced with high ceilings, and canteens are consistently the loudest rooms.
Work reaching us from Paris is mostly haussmann apartments, offices, studios, restaurants, hotels, clinics.
- Parquet over timber joists Footfall and chair scrape travel straight down. A resilient layer under the finish does more than anything applied to the ceiling below.
- Thin partitions in divided apartments Walls built to split one flat into two were never designed to hold speech. Mass and an independent lining are the honest answer.
- Courtyards that amplify A Paris courtyard reflects plant noise and voices between every window on the block. Treat the source or the surface, not the middle.
- 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 Paris.
02 / The build-up
What goes where, from the structure in
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Paris, mechanical extract ventilation is near universal, and the extract path carries sound between flats as reliably as the wall.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
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 Paris, churches, salles des fetes and civic auditoriums are stone and plaster volumes with very long decay.
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 Paris, school buildings are hard surfaced with high ceilings, and canteens are consistently the loudest rooms.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
Architects working in Paris usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / On the ground
The Paris conditions that change the answer
- Parquet over timber joists
Footfall and chair scrape travel straight down. A resilient layer under the finish does more than anything applied to the ceiling below.
- Thin partitions in divided apartments
Walls built to split one flat into two were never designed to hold speech. Mass and an independent lining are the honest answer.
- Courtyards that amplify
A Paris courtyard reflects plant noise and voices between every window on the block. Treat the source or the surface, not the middle.
- Small rooms
Depth is expensive when a room is 12 square metres. Slim, dense layers beat thick absorbers you cannot afford to lose space to.
- Assembly and performance rooms
Churches, salles des fetes and civic auditoriums are stone and plaster volumes with very long decay.
- School and campus buildings
School buildings are hard surfaced with high ceilings, and canteens are consistently the loudest rooms.
04 / Room by room
Space by space, for Paris briefs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Footfall and chair scrape travel straight down. A resilient layer under the finish does more than anything applied to the ceiling below.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. Walls built to split one flat into two were never designed to hold speech. Mass and an independent lining are the honest answer.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic panels, ASTM C423
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. A Paris courtyard reflects plant noise and voices between every window on the block. Treat the source or the surface, not the middle.
- PET felt acoustic panels, 4 to 24 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
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 Paris climate rules in and rules out
Paris is cool and damp, with long heating seasons and cold external walls, and that narrows the material list before acoustics is discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The failure we design against here is condensation behind linings in older, poorly insulated stock.
On a Paris job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

What we watch go wrong on jobs like this
-
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 Paris job
Footfall and chair scrape travel straight down. A resilient layer under the finish does more than anything applied to the ceiling below.

Questions from Paris projects
What makes school and classroom acoustics different in Paris?
School buildings are hard surfaced with high ceilings, and canteens are consistently the loudest rooms. Footfall and chair scrape travel straight down. A resilient layer under the finish does more than anything applied to the ceiling below.
Where should the budget go first on a Paris 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 Paris?
No. We manufacture in India and supply into Paris. 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 Paris site?
ships from: Palwal, Haryana, India, arrives at: Le Havre, Antwerp or Rotterdam, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved and custom colours take longer, and we say so before the 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
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
