School and classroom acoustics in Vienna
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 and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.
- 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 product, described honestly, for a Vienna brief
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 and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.
Work reaching us from Vienna is mostly gründerzeit apartments, offices, studios, restaurants, clinics, schools, hotels.
- Gründerzeit rooms are tall and hard High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
- Timber floors between apartments Footfall travels down through the joists into the flat below. A resilient layer under the finish does far more than anything applied to the ceiling underneath.
- Quiet hours are taken seriously Neighbour complaints here are not shrugged off. The isolation layer is what protects a home studio, a practice room or a late venue from becoming somebody else problem.
- 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 Vienna.
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 Vienna, mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Vienna, concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Vienna, school and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
The Vienna conditions that change the answer
- Gründerzeit rooms are tall and hard
High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
- Timber floors between apartments
Footfall travels down through the joists into the flat below. A resilient layer under the finish does far more than anything applied to the ceiling underneath.
- Quiet hours are taken seriously
Neighbour complaints here are not shrugged off. The isolation layer is what protects a home studio, a practice room or a late venue from becoming somebody else problem.
- Trams and the Ring
Ground level trams and traffic put low frequency into the structure. Panels on a wall will not touch it, and we will say so rather than sell them.
- Assembly and performance rooms
Concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
- School and campus buildings
School and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.

Where the money goes on a Vienna project
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Wood wool acoustic panels, 20 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. Footfall travels down through the joists into the flat below. A resilient layer under the finish does far more than anything applied to the ceiling 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
- Acoustic panels, ASTM C423
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Neighbour complaints here are not shrugged off. The isolation layer is what protects a home studio, a practice room or a late venue from becoming somebody else problem.
- PET felt acoustic panels, 4 to 24 mm
- Wood wool acoustic panels, 0.30
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
Why the climate in Vienna changes the material, not the target
Vienna 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
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 Vienna job
High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
05 / Supply
What the route into Vienna actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Koper or Hamburg, then rail and road into Vienna |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Koper or Hamburg |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
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.

Questions from Vienna projects
What makes school and classroom acoustics different in Vienna?
School and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail. High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
Where should the budget go first on a Vienna 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 Vienna?
No. We manufacture in India and supply into Vienna. 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 Vienna site?
ships from: Palwal, Haryana, India, arrives at: Koper or Hamburg, then rail and road into Vienna, 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
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.
