School and classroom acoustics in France
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 / The product
What this is, and what it changes in a France 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.
School buildings are hard surfaced with high ceilings, and canteens are consistently the loudest rooms.
Work reaching us from France is mostly apartments, hotels, restaurants, offices, studios, schools, clinics.
- Retrofit, not new build Most rooms already exist, so the build-up has to work within the depth and the finishes you already have.
- Timber floors and divided apartments Footfall and speech move between homes through the floor. Mass plus a resilient layer beats any surface treatment underneath.
- Hospitality volume Restaurants and hotels take the acoustic complaints personally, because guests write them down. Absorption goes where it will not fight the design.
- 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 France.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In France, mechanical extract ventilation is near universal, and the extract path carries sound between flats as reliably as the wall.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
-
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 France, churches, salles des fetes and civic auditoriums are stone and plaster volumes with very long decay.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In France, 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 France 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
What we see driving France briefs
- Retrofit, not new build
Most rooms already exist, so the build-up has to work within the depth and the finishes you already have.
- Timber floors and divided apartments
Footfall and speech move between homes through the floor. Mass plus a resilient layer beats any surface treatment underneath.
- Hospitality volume
Restaurants and hotels take the acoustic complaints personally, because guests write them down. Absorption goes where it will not fight the design.
- Seasonal programmes
Coastal and resort work runs to a fixed opening date. We give honest dispatch and transit dates so the fit-out is not waiting on a container.
- 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
What each space in a France project needs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Most rooms already exist, so the build-up has to work within the depth and the finishes you already have.
- 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. Footfall and speech move between homes through the floor. Mass plus a resilient layer beats any surface treatment underneath.
- 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. Restaurants and hotels take the acoustic complaints personally, because guests write them down. Absorption goes where it will not fight the design.
- PET felt acoustic panels, 4 to 24 mm
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
For a France interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Durability
What the France climate rules in and rules out
France 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.
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 / Before you buy
Six mistakes that turn into a second fit-out
-
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 France job
Most rooms already exist, so the build-up has to work within the depth and the finishes you already have.

Questions from France projects
What makes school and classroom acoustics different in France?
School buildings are hard surfaced with high ceilings, and canteens are consistently the loudest rooms. Most rooms already exist, so the build-up has to work within the depth and the finishes you already have.
Where should the budget go first on a France 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 France?
No. We manufacture in India and supply into France. 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 France site?
ships from: Palwal, Haryana, India, arrives at: Le Havre, Marseille or Antwerp, then road to site, 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 you order.
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
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.
