Manufactured in India, supplied in Hanoi
Wood wool acoustic panels in Hanoi
We manufacture wood wool 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.

- 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 / The product
What you are buying, and what it fixes in Hanoi
Wood fibre bound into a rigid board with an open texture. Robust, paintable and used where the surface takes knocks, which is why it ends up in schools, sports halls and plant rooms.
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.
- Direct fix Mechanically fixed to the soffit or wall. Durable and simple.
- On a cavity Mounted on battens with an air gap, which is where the low mid performance comes from.
- With a porous backing Board over mineral backing where the room needs more than the board alone gives.
- What it will not do At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wood wool panels are on the main product page. This page covers what that means for a project in Hanoi.
02 / Specification
The published figures, unchanged by location
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings
| Panel size | 1200 x 600 mm |
|---|---|
| Thickness | 20 mm |
| Density | 400 kg per cubic metre |
| NRC | 0.30 |
| Test standards | ASTM C-423 and EN ISO 354 |
| Surface burning | Class A to ASTM E84 |
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
03 / Local conditions
What we see driving Hanoi briefs
- 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.
- Assembly and performance rooms
Function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are hard, naturally ventilated and open to street noise, with large class sizes.
Architects working in Hanoi 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
The Hanoi climate decides the material list
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.
For a Hanoi 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 Hanoi actually looks like
| 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, edge protected. Boards are rigid but the edges chip, so they travel protected. |
| Lead time | 4 to 7 working days for standard sizes. |
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.
The same 500 sq ft minimum applies on export.
| Any finish | 500 sq ft, about 46 sq m |
|---|
A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels.
06 / Straight talk
Where this goes wrong, said plainly
-
The wrong product for the problem
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
-
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.

Suppliers who imply a Hanoi presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Hanoi: questions we are actually asked
Are these wood wool acoustic panels made in Hanoi?
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.
What changes the specification on a Hanoi job?
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.
Is this the right material for Hanoi conditions?
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 does an order actually travel to 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 wood wool acoustic panels the wrong purchase?
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
What quantity do we have to order, and in what packaging?
The same 500 sq ft minimum applies on export. Any finish, 500 sq ft, about 46 sq m. A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels. Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected.
