Manufactured in India, supplied in Hanoi
Acoustic panels in Hanoi
We manufacture acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Hanoi. Made at our own plant in India and shipped into Haiphong, then 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
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 product, described honestly, for a Hanoi 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 Hanoi is mostly manufacturing plants, tube houses and apartments, offices, hotels, schools, clinics.
Tube houses and apartment towers in concrete and block, sharing walls with neighbours on both sides and hard floors throughout.
- 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 Hanoi.

02 / Specification
The numbers, and they do not move by city
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

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 the buildings in Hanoi do to the specification
- Hot, humid, monsoon
PET felt does not absorb moisture or feed mould, which matters where mineral products sag in a couple of seasons.
- Narrow, deep buildings
The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides.
- Continuous street noise
Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.
- New manufacturing at pace
Plants going up quickly on greenfield sites, where enclosure and partition detail can still be designed in.
- School and campus buildings
Classrooms are hard, naturally ventilated and open to street noise, with large class sizes.
- The studio and content scene
A fast growing content scene works out of rooms in tube houses and commercial floors with thin partitions.
For a Hanoi practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
Why the climate in Hanoi changes the material, not the target
Hanoi is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The risk we design against here is mould, sagging fabric finishes and swelling in timber.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Supply
Getting it to Hanoi, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Haiphong, then road into Hanoi |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Haiphong |
| 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 Haiphong, then road into Hanoi. 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.

What we will tell you that a reseller will not
-
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.
-
Local approvals that nobody actually holds
We hold no Hanoi certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

The material in real interiors
Hanoi: questions we are actually asked
Where are the acoustic panels you supply to Hanoi actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Hanoi as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Haiphong, then 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 Hanoi build-up differ from anywhere else?
The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides. Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first. Those two things move the build-up far more than the panel figure does.
Does Hanoi weather shorten the life of this material?
Hanoi is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.
How quickly can material reach a site in Hanoi?
ships from: Palwal, Haryana, India, arrives at: Haiphong, then road into Hanoi, 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.
When are acoustic panels the wrong purchase?
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.
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. 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.
