Manufactured in India, supplied in Seoul
PET felt acoustic panels in Seoul
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Seoul. Made at our own plant in India and shipped into Incheon, close to the city, so the road leg after the port is short.

01 / What it is
The product, described honestly, for a Seoul 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 Seoul is mostly apartment towers, offices, studios and content rooms, cafes and dining, clinics, schools.
Reinforced concrete apartment towers with underfloor heating and hard floors. Impact noise between floors is the single biggest residential complaint.
- 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 Seoul.
02 / Specification
Published specification, identical wherever we ship it
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

03 / In this market
What decides the build-up in Seoul
- It is the floor, not the wall
Impact noise from above dominates complaints in this city. The fix goes under the finish before the finish goes down, not on the ceiling afterwards.
- Content rooms everywhere
Studios, streaming rooms and practice spaces inside residential and commercial towers. Isolation from the building is what makes them usable.
- Dense, vertical, mixed use
Cafes and venues sit underneath homes in the same structure, so containment decides trading hours.
- Incheon is close
A short road leg after the port keeps landed cost and dates predictable.
- School and campus buildings
School and academy buildings are hard surfaced with long corridors and very intensive use.
Architects working in Seoul usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Climate and durability
The Seoul climate decides the material list
Seoul is hot summers, mild winters and a distinct wet season, and that narrows the sensible material list before acoustics is even discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The risk we design against here is wet-season humidity behind linings.
For a Seoul interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Route to site
What the route into Seoul actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Incheon, then a short road run into Seoul |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Incheon |
| 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 Incheon, then a short road run into Seoul. 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 / Worth knowing
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 Seoul
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.
Seoul: questions we are actually asked
Where are the PET felt acoustic panels you supply to Seoul actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Seoul as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Incheon, close to the city, so the road leg after the port is short. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Seoul job?
Impact noise from above dominates complaints in this city. The fix goes under the finish before the finish goes down, not on the ceiling afterwards. Studios, streaming rooms and practice spaces inside residential and commercial towers. Isolation from the building is what makes them usable. Those two things move the build-up far more than the panel figure does.
Is this the right material for Seoul conditions?
Seoul is hot summers, mild winters and a distinct wet season. PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH. The failure we design against here is wet-season humidity behind linings.
How does an order actually travel to Seoul?
ships from: Palwal, Haryana, India, arrives at: Incheon, then a short road run into Seoul, 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.
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.

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.
