School and classroom acoustics in Amsterdam
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 well insulated and airtight with hard cleanable surfaces, so rooms stay live and ventilation noise is always present.
- 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 Amsterdam 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 well insulated and airtight with hard cleanable surfaces, so rooms stay live and ventilation noise is always present.
Work reaching us from Amsterdam is mostly canal house apartments, hotels, offices in Zuid and Noord, studios, bars, clinics.
- Canal houses carry everything Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
- Listed facades, internal fixes only On a monument you cannot change the outside and often cannot change the structure. Everything has to be done from the inside, shallow, and ideally reversible.
- Venue noise limits are enforced Amsterdam operators live with real decibel and low frequency conditions on their permits, and the low end is what gets them into trouble. Containment is not optional here, it is the licence.
- 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 Amsterdam.
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 Amsterdam, balanced mechanical ventilation is standard, so duct and terminal unit noise replace open window noise.
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 Amsterdam, church buildings, civic halls and converted industrial spaces have long decay times and hard surfaces throughout.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Amsterdam, school buildings are well insulated and airtight with hard cleanable surfaces, so rooms stay live and ventilation noise is always present.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
For a Amsterdam practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

What we see driving Amsterdam briefs
- Canal houses carry everything
Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
- Listed facades, internal fixes only
On a monument you cannot change the outside and often cannot change the structure. Everything has to be done from the inside, shallow, and ideally reversible.
- Venue noise limits are enforced
Amsterdam operators live with real decibel and low frequency conditions on their permits, and the low end is what gets them into trouble. Containment is not optional here, it is the licence.
- Recycled content gets asked first
Our PET felt is made from recycled bottle flake. In Dutch tenders that question comes before the acoustic one, and it is the easiest one for us to answer honestly.
- Assembly and performance rooms
Church buildings, civic halls and converted industrial spaces have long decay times and hard surfaces throughout.
- School and campus buildings
School buildings are well insulated and airtight with hard cleanable surfaces, so rooms stay live and ventilation noise is always present.

Space by space, for Amsterdam briefs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
- 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. On a monument you cannot change the outside and often cannot change the structure. Everything has to be done from the inside, shallow, and ideally reversible.
- 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. Amsterdam operators live with real decibel and low frequency conditions on their permits, and the low end is what gets them into trouble. Containment is not optional here, it is the licence.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic panels, ASTM C423
- Acoustic carpet and rugs, 64 sq ft per pack
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Climate and durability
Durability in Amsterdam, before acoustics is discussed
Amsterdam 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 Amsterdam job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Straight talk
The six errors that cost the most
-
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
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 Amsterdam job
Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
05 / Route to site
How material reaches a Amsterdam site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Rotterdam, then a short road run into the city |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Rotterdam |
| 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 tell you that before you order, not after.
Sea freight into Rotterdam, then road into Amsterdam. Being close to the port keeps the inland cost low. Air freight for samples and urgent quantities.
Questions from Amsterdam projects
What makes school and classroom acoustics different in Amsterdam?
School buildings are well insulated and airtight with hard cleanable surfaces, so rooms stay live and ventilation noise is always present. Seventeenth century houses were built narrow and tall with timber floors on shared party walls. Footfall and speech travel down and sideways, which is why a resilient layer under the finish beats anything hung on a wall.
Where should the budget go first on a Amsterdam 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 Amsterdam?
No. We manufacture in India and supply into Amsterdam. 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 Amsterdam site?
ships from: Palwal, Haryana, India, arrives at: Rotterdam, then a short road run into the city, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we tell you that 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.
