Manufactured in India, supplied in Prague
Acoustic panels in Prague
We manufacture acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Prague. Made at our own plant in India and shipped into Hamburg, then rail and road into the city, with the inland leg written into the dates we quote.
- 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
This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / What it is
The product, described honestly, for a Prague brief
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 Prague is mostly hotel conversions, apartments, production and studio spaces, offices, restaurants, clinics.
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
- 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 Prague.

02 / The numbers
One specification sheet, the same in every market
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. General commercial
- EchoPro 181800 GSM. Rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

On a Prague job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
What we see driving Prague briefs
- Protected buildings, internal fixes only
In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems.
- Conversions into guest rooms
Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else.
- A production city
Stages, edit rooms and post production spaces need the shell to isolate before anything else is decided. There is no partial credit on a room like that.
- Hard stone, long reverberation
Stone, plaster and tile in tall rooms hold sound for a long time. Speech stops being intelligible well before the room sounds obviously wrong.
- School and campus buildings
School buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.
- The studio and content scene
A strong recording tradition, with rooms fitted into older buildings where the structure helps and the surfaces do not.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Conditions
The Prague climate decides the material list
Prague is cool and damp, with long heating seasons and cold external walls, and that narrows the sensible material list before acoustics is even 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 risk we design against here is condensation behind linings in older, poorly insulated 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 / Route to site
Getting it to Prague, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hamburg, then rail and road into Prague |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Hamburg |
| 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 Hamburg, then rail and road into Prague. 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.

Four honest warnings before you buy
-
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.
-
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 Prague
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.

The material in real interiors
Prague: questions we are actually asked
Do you manufacture acoustic panels in Prague?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Prague as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Hamburg, then rail and road into the city, with the inland leg written into the dates we quote. You buy at factory prices with one consistent batch across the order.
Why would a Prague build-up differ from anywhere else?
In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems. Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else. Those two things move the build-up far more than the panel figure does.
Will this material last in the Prague climate?
Prague is cool and damp, with long heating seasons and cold external walls. 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.
When would material land on a Prague site?
ships from: Palwal, Haryana, India, arrives at: Hamburg, then rail and road into Prague, 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 will acoustic panels not do?
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.
How is the order packed and what is the minimum?
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.

We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
