Manufactured in India, supplied in Sweden
PET felt acoustic panels in Sweden
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Sweden. Made at our own plant in India and shipped into Gothenburg, then road onward, with the domestic leg quoted separately because Sweden is a long country.

- 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 / Start here
The material, and what it actually does on a Sweden 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 Sweden is mostly timber buildings and apartments, offices, schools, healthcare, hotels, studios.
Concrete apartment blocks and timber frame housing with tight envelopes, hard floors and cold external walls.
- 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 Sweden.
02 / Specification 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. 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 decides the build-up in Sweden
- Classes are written and verified
Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it.
- Timber at scale
Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work.
- Sealed through a long winter
Ventilation runs constantly in closed buildings, so plant noise matters more than street noise.
- A long country
A site in the north has a real domestic leg. We quote it separately so the dates are honest.
- School and campus buildings
Classroom acoustics are regulated, and open plan learning areas make speech intelligibility the design target.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate and durability
What the Sweden climate rules in and rules out
Sweden 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.
For a Sweden interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Logistics
Getting it to Sweden, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Gothenburg, then road onward to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Gothenburg |
| 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. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into Gothenburg, then road onward 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, 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.
06 / Straight talk
Where this goes wrong, said plainly
-
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.
-
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 Sweden
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.
Sweden: questions we are actually asked
Are these PET felt acoustic panels made in Sweden?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Sweden as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Gothenburg, then road onward, with the domestic leg quoted separately because Sweden is a long country. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Sweden enquiry?
Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it. Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work. Those two things move the build-up far more than the panel figure does.
Does Sweden weather shorten the life of this material?
Sweden 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 Sweden?
ships from: Palwal, Haryana, India, arrives at: Gothenburg, then road onward to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
What will PET felt acoustic panels not do?
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 quantity do we have to order, and in what packaging?
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
Send a plan and a section, get a real build-up
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.
