Manufactured in India, supplied in Hong Kong
PET felt acoustic panels in Hong Kong
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Hong Kong. Made at our own plant in India and shipped straight into Hong Kong, so the container lands where it is needed rather than a road leg away.

01 / Start here
What you are buying, and what it fixes in Hong Kong
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 Hong Kong is mostly apartments, offices, hotels and dining, clinics, schools, studios.
Very dense reinforced concrete towers with hard floors and minimal separation between units. Impact and airborne noise between flats is constant.
- 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 Hong Kong.
02 / Data sheet
Published specification, identical wherever we ship it
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

03 / In this market
What the buildings in Hong Kong do to the specification
- Depth is the expensive part
Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost.
- Concrete towers, live rooms
The structure blocks a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer.
- Plant on every roof and podium
Cooling plant sits within metres of windows in a dense city, so plant noise reaches more people than any single source.
- The port is right here
Direct sea into Hong Kong keeps the chain short and the landed cost predictable.
- School and campus buildings
School buildings are compact and hard surfaced with very intensive use and no spare volume.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Conditions
The Hong Kong climate decides the material list
Hong Kong 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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Getting it there
Supply into Hong Kong, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hong Kong, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Hong Kong |
| 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 direct into Hong Kong, 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, 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
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.
-
Local approvals that nobody actually holds
We hold no Hong Kong certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Hong Kong: questions we are actually asked
Are these PET felt acoustic panels made in Hong Kong?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Hong Kong as the manufacturer rather than through a dealer. Made at our own plant in India and shipped straight into Hong Kong, so the container lands where it is needed rather than a road leg away. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Hong Kong enquiry?
Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost. The structure blocks a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer. Those two things move the build-up far more than the panel figure does.
How does the Hong Kong climate affect this product?
Hong Kong 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.
What is the delivery time into Hong Kong?
ships from: Palwal, Haryana, India, arrives at: Hong Kong, 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.
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.
Is there a minimum order, and how does it arrive?
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.

Send a plan and a section, get a real 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.
