- 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 material, and what it actually does on a Czechia job
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 Czechia is mostly production halls, plant rooms, offices, panel block apartments, schools, clinics.
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
- 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 Czechia.
02 / Specification
The published figures, unchanged by location
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- 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

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 / On the ground
What we see driving Czechia briefs
- Panel block apartments
Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
- Industrial noise is a mass problem
Compressors, presses and extraction plant are low frequency and structure-borne. We will tell you when absorption is the wrong purchase rather than sell it to you.
- Value is checked properly
Czech buyers compare specifications line by line. That suits a manufacturer, because we can answer for what is actually in the product.
- Landlocked, so plan the inland leg
Hamburg then rail and road. We quote the sea leg and the inland leg separately so the programme is built on real dates.
- School and campus buildings
School buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.
For a Czechia practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Durability
Why the climate in Czechia changes the material, not the target
Czechia 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 / Logistics
What the route into Czechia actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hamburg, then rail and road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Hamburg |
| 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 Hamburg, then rail and road inland. 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.

Four honest warnings before you buy
-
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 Czechia
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.
Czechia: questions we are actually asked
Are these PET felt acoustic panels made in Czechia?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Czechia as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Hamburg, then rail and road inland, with container pricing that suits the way Czech projects buy. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Czechia enquiry?
Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do. Compressors, presses and extraction plant are low frequency and structure-borne. We will tell you when absorption is the wrong purchase rather than sell it to you. Those two things move the build-up far more than the panel figure does.
Is this the right material for Czechia conditions?
Czechia 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.
How does an order actually travel to Czechia?
ships from: Palwal, Haryana, India, arrives at: Hamburg, then rail and road inland, 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.
Where do PET felt acoustic panels fail to help?
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.
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, 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.
Next step
Tell us the room, we will tell you the build-up
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
