Manufactured in India, supplied in Japan
Wood wool acoustic panels in Japan
We manufacture wood wool acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Japan. Made at our own plant in India and shipped into Yokohama or Kobe, then road to site, with the full window quoted rather than the port date.

- 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 Japan
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 Japan is mostly apartments and houses, offices, studios, hotels, schools, clinics.
Timber frame houses and reinforced concrete mansions, with thin partitions in older stock and tight urban spacing 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 Japan.
02 / Data sheet
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.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings

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 / In this market
The Japan conditions that change the answer
- Humid summers
PET felt does not hold moisture or feed mould, which matters through a humid season in a sealed room.
- Small rooms, close neighbours
Depth is genuinely scarce, so a thin build-up that performs is worth more than a thicker one that performs marginally better.
- Designed to move
Seismic detailing means junctions that must stay flexible. An acoustic layer cannot bridge a movement joint rigidly.
- Precise expectations
Specifications here are written carefully and checked properly. Send us the target and we will say plainly what our material reaches.
- Assembly and performance rooms
Halls, temples and civic auditoria range from very controlled to very reverberant, and both need measured targets.
- School and campus buildings
School buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.
If you are specifying for a Japan project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate and durability
The Japan climate decides the material list
Japan 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.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
05 / Logistics
Supply into Japan, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Yokohama or Kobe, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Yokohama |
| 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. 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 Yokohama or Kobe, then road to site. 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 / Before you buy
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.
-
Local approvals that nobody actually holds
We hold no Japan certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Japan: questions we are actually asked
Where are the wood wool acoustic panels you supply to Japan actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Japan as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Yokohama or Kobe, then road to site, with the full window quoted rather than the port date. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Japan project?
Depth is genuinely scarce, so a thin build-up that performs is worth more than a thicker one that performs marginally better. Seismic detailing means junctions that must stay flexible. An acoustic layer cannot bridge a movement joint rigidly. Those two things move the build-up far more than the panel figure does.
Does Japan weather shorten the life of this material?
Japan 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 Japan?
ships from: Palwal, Haryana, India, arrives at: Yokohama or Kobe, then road 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 should you not buy wood wool acoustic panels for?
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.
