Manufactured in India, supplied in Madrid

- One batch across the order, no blending between runs
We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / What it is
The product, described honestly, for a Madrid brief
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. It absorbs mid and high frequency energy and finishes as the visible surface, so it is both the acoustic layer and the finish.
Work reaching us from Madrid is mostly ensanche apartments, Castellana office floors, restaurants, hotels, clinics, studios, schools.
The Ensanche and equivalent city blocks stack flats around a patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem.
- Direct to wall Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
- 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.
- Over a porous backing Panel over mineral or PET backing where the room needs genuine low mid control.
- What it will not do It absorbs. It does not block.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for PET felt panels are on the main product page. This page covers what that means for a project in Madrid.
02 / Data sheet
Published specification, identical wherever we ship it
Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.
- EchoCore 151500 GSM. Offices, classrooms, general commercial
- EchoPro 181800 GSM. Studios, auditoria, rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

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.
03 / On the ground
What decides the build-up in Madrid
- 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.
- 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.
- 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.
- 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.
- 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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate and durability
Durability in Madrid, before acoustics is discussed
Madrid is hot dry summers and mild wet winters, and that narrows the sensible material list before acoustics is even 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 risk we design against here is seasonal movement in timber and winter damp in unheated stock.
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.
05 / Logistics
How material reaches a Madrid site
| 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 |
| Packing | Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote. |
| Lead time | 4 to 7 working days for standard colours and thicknesses. Grooved and custom colours take longer, and we say so before you order. |
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.
200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use.
| Trial order | 200 panels, 6,400 sq ft, mixed thickness, GSM and colour |
|---|---|
| Recommended | Full container, for the best price per panel and the lowest freight per panel |
A panel is 1220 x 2440 mm, which is 32 sq ft.

The things worth knowing before you place the order
-
The wrong product for the problem
It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.
-
A claim of being local to Madrid
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.
Madrid: questions we are actually asked
Is there a Madrid factory behind this product?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Madrid as the manufacturer rather than through a dealer. Made at our own plant in India, shipped into Valencia or Barcelona and trucked inland to Madrid, with the road leg built into the dates we quote rather than left out of them. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Madrid project?
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. 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. Those two things move the build-up far more than the panel figure does.
Does Madrid weather shorten the life of this material?
Madrid is hot dry summers and mild wet winters. 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.
When would material land on 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 should you not buy PET felt acoustic panels for?
It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.
What is the minimum order and how is it packed?
200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container, for the best price per panel and the lowest freight per panel. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
