School and classroom acoustics in Zurich
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 built to a high standard with hard cleanable surfaces, so rooms stay live and intelligibility is the target.
- 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 material
What you are buying, and what it fixes in Zurich
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 built to a high standard with hard cleanable surfaces, so rooms stay live and intelligibility is the target.
Work reaching us from Zurich is mostly banking and professional offices, industrial conversions, apartments, clinics, restaurants, studios.
- Confidentiality is the requirement On a banking or professional floor the question is not comfort, it is whether a conversation leaves the room. Absorption plus a proper partition and door detail is what delivers that.
- Industrial conversions in the west Old industrial buildings give superb volume and terrible acoustics. Hard shells, big cubic volume and nothing soft, so the ceiling plane has to carry the whole room.
- Depth costs real money here Zurich floor area is among the most expensive in Europe. A thinner build-up that performs is worth more than a thicker one that performs slightly better.
- 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 Zurich.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Zurich, mechanical ventilation with heat recovery is standard, so duct and terminal unit noise are the sources.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Zurich, concert halls, church buildings and civic rooms are long-decay volumes where interventions must be reversible.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
-
Layer 3
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 Zurich, school buildings are built to a high standard with hard cleanable surfaces, so rooms stay live and intelligibility is the target.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
If you are specifying for a Zurich project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / Local conditions
What decides the build-up in Zurich
- Confidentiality is the requirement
On a banking or professional floor the question is not comfort, it is whether a conversation leaves the room. Absorption plus a proper partition and door detail is what delivers that.
- Industrial conversions in the west
Old industrial buildings give superb volume and terrible acoustics. Hard shells, big cubic volume and nothing soft, so the ceiling plane has to carry the whole room.
- Depth costs real money here
Zurich floor area is among the most expensive in Europe. A thinner build-up that performs is worth more than a thicker one that performs slightly better.
- Trams and dense streets
Ground level trams put low frequency into the structure. That is a structural isolation question, and panels on a wall will not answer it.
- Assembly and performance rooms
Concert halls, church buildings and civic rooms are long-decay volumes where interventions must be reversible.
- School and campus buildings
School buildings are built to a high standard with hard cleanable surfaces, so rooms stay live and intelligibility is the target.
04 / Room by room
Space by space, for Zurich briefs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. On a banking or professional floor the question is not comfort, it is whether a conversation leaves the room. Absorption plus a proper partition and door detail is what delivers that.
- 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. Old industrial buildings give superb volume and terrible acoustics. Hard shells, big cubic volume and nothing soft, so the ceiling plane has to carry the whole room.
- 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. Zurich floor area is among the most expensive in Europe. A thinner build-up that performs is worth more than a thicker one that performs slightly better.
- 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 / Climate and durability
What the Zurich climate rules in and rules out
Zurich 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.
Where a consultant is already engaged on a Zurich project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Before you buy
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
This is the one that comes back as a second fit-out rather than a snag.
-
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 Zurich job
On a banking or professional floor the question is not comfort, it is whether a conversation leaves the room. Absorption plus a proper partition and door detail is what delivers that.

Questions from Zurich projects
What makes school and classroom acoustics different in Zurich?
School buildings are built to a high standard with hard cleanable surfaces, so rooms stay live and intelligibility is the target. On a banking or professional floor the question is not comfort, it is whether a conversation leaves the room. Absorption plus a proper partition and door detail is what delivers that.
Where should the budget go first on a Zurich 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 Zurich?
No. We manufacture in India and supply into Zurich. 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 Zurich site?
ships from: Palwal, Haryana, India, arrives at: Rotterdam or Antwerp, then rail into Zurich, 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
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.
