Manufactured in India, supplied in Lisbon
Acoustic panels in Lisbon
We manufacture acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Lisbon. Made at our own plant in India and shipped into Lisbon or Sines, then a short road run to site, with narrow street access planned into how we pack.
- Plain PET felt
- 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
- Printed felt
- 1800 x 900 mm, image printed into the felt rather than onto a facing
- Grooved panels
- Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Test standard
- ASTM C423
- Lead time
- 4 to 7 working days standard
- Minimum order
- From 10 panels
- ASTM C423
- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.
01 / The material
What this material is and where it earns its place in Lisbon
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.
Work reaching us from Lisbon is mostly hotel and short let conversions, apartments, restaurants, offices, clinics, studios.
Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards.
- Wall array Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
- Ceiling first In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
- Mixed finish Plain felt where it is out of eye line, printed or grooved where it is seen.
- What it will not do Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our acoustic panel range are on the main product page. This page covers what that means for a project in Lisbon.

02 / Data sheet
One specification sheet, the same in every market
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- EchoCore 151500 GSM. General commercial
- EchoPro 181800 GSM. Rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
03 / Local conditions
What decides the build-up in Lisbon
- Conversions put beds either side of old walls
A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
- Timber floors, every floor
Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Hills and narrow streets
Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.
- Late districts under homes
Venues in the old districts operate directly beneath apartments. Low frequency containment is what keeps the operation trading.
- School and campus buildings
School buildings are hard surfaced with high ceilings, and canteens are the loudest rooms.
- The studio and content scene
Studios go into converted older buildings with good mass and hard surfaces, often with neighbours above.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Durability
Why the climate in Lisbon changes the material, not the target
Lisbon 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.
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.
05 / Supply
What the route into Lisbon actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Lisbon or Sines, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Lisbon or Sines |
| Packing | Palletised flat and film wrapped. Printed panels interleaved and corner protected. |
| Lead time | 4 to 7 working days standard. Printed and grooved take longer. |
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 Lisbon or Sines, then a short road run to site. 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.
| Trial order | 200 panels, 6,400 sq ft, mixed thickness, GSM and colour |
|---|---|
| Recommended | Full container |
A panel is 1220 x 2440 mm, which is 32 sq ft.

What we will tell you that a reseller will not
-
The wrong product for the problem
Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant. We would rather calculate the area than sell the wall.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.

A claim of being local to Lisbon
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.

How it looks once it is installed
Lisbon: questions we are actually asked
Do you manufacture acoustic panels in Lisbon?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Lisbon as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Lisbon or Sines, then a short road run to site, with narrow street access planned into how we pack. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Lisbon job?
A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves. Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it. Those two things move the build-up far more than the panel figure does.
Is this the right material for Lisbon conditions?
Lisbon 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 Lisbon site?
ships from: Palwal, Haryana, India, arrives at: Lisbon or Sines, then a short road run to site, 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.
When are acoustic panels the wrong purchase?
Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant. We would rather calculate the area than sell the wall.
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. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped. Printed panels interleaved and corner protected.
