School and classroom acoustics in Madrid
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 concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building.
- 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 Madrid 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 concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building.
Work reaching us from Madrid is mostly ensanche apartments, Castellana office floors, restaurants, hotels, clinics, studios, schools.
- Ensanche blocks share everything The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- Castellana floors have nothing soft Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- A city that eats and drinks late Bars and restaurants run long hours directly under apartments. The complaint is almost always low frequency and footfall, and it arrives fast.
- 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 Madrid.
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 Madrid, split and multi-split systems dominate, with condensers in patios and light wells that act as reverberant shafts.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
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 Madrid, churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times.
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 Madrid, school buildings are concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
Architects working in Madrid 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 decides the build-up in Madrid
- Ensanche blocks share everything
The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- Castellana floors have nothing soft
Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- A city that eats and drinks late
Bars and restaurants run long hours directly under apartments. The complaint is almost always low frequency and footfall, and it arrives fast.
- Closed up against the heat
Once a room is sealed and air conditioned it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
- Assembly and performance rooms
Churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times.
- School and campus buildings
School buildings are concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building.

Room by room, on a typical Madrid job
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- 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. Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- 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. Bars and restaurants run long hours directly under apartments. The complaint is almost always low frequency and footfall, and it arrives fast.
- 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 / Climate
Why the climate in Madrid changes the material, not the target
Madrid is hot dry summers and mild wet winters, and that narrows the material list before acoustics is discussed.
The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing.
The failure we design against here is seasonal movement in timber and winter damp in unheated stock.
Where a consultant is already engaged on a Madrid project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
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
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
Treating it as a generic Madrid job
The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
05 / Route to site
What the route into Madrid actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Valencia or Barcelona, then road inland to Madrid |
| Dispatch | 4 to 7 working days |
| Freight | Sea, then road inland |
| 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.
Sea freight into Valencia or Barcelona, then road inland to Madrid. Air freight for samples and urgent quantities.
Questions from Madrid projects
What makes school and classroom acoustics different in Madrid?
School buildings are concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building. The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
Where should the budget go first on a Madrid 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 Madrid?
No. We manufacture in India and supply into Madrid. 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 Madrid site?
ships from: Palwal, Haryana, India, arrives at: Valencia or Barcelona, then road inland to Madrid, 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.
