Manufactured in India, supplied in Japan
Acoustic foam and BassBloc in Japan
We manufacture acoustic foam and BassBloc 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.
- BassBloc size
- 1800 x 900 mm
- BassBloc thickness
- 20 mm
- BassBloc density
- 100 kg per cubic metre
- Effective range
- 100 to 500 Hz
- BassBloc NRC
- 0.85
- Lead time
- 4 to 7 working days
- Minimum order
- From 200 sq ft
- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
- Test reports sent on request, not just quoted
Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.
01 / The product
What you are buying, and what it fixes in Japan
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing.
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.
- Corner loading Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
- First reflection points Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
- Behind a fabric frame Where the room has to look finished, absorber inside a frame rather than foam on show.
- What it will not do Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for acoustic foam and bass traps are on the main product page. This page covers what that means for a project in Japan.
02 / Specification sheet
One specification sheet, the same in every market
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.
- Foam wedge and pyramidLow density. Flutter and high frequency only
- BassBloc100 kg per cubic metre. Low mid absorption, control rooms, live rooms
| BassBloc size | 1800 x 900 mm |
|---|---|
| BassBloc thickness | 20 mm |
| BassBloc density | 100 kg per cubic metre |
| Effective range | 100 to 500 Hz |
| BassBloc NRC | 0.85 |
On a Japan job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / In this market
What the buildings in Japan do to the specification
- 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.
- Humid summers
PET felt does not hold moisture or feed mould, which matters through a humid season in a sealed room.
- The housing stock
Timber frame houses and reinforced concrete mansions, with thin partitions in older stock and tight urban spacing throughout.
- The studio and content scene
A deep music and broadcast culture where isolation is expected and specified, not improvised.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate
Durability in Japan, before acoustics is discussed
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.
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
05 / Route to site
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 | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 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.
Sea freight into Yokohama or Kobe, then road to site. Air freight for samples and urgent quantities.
The same minimums apply on export.
| Acoustic foam | 200 sq ft, about 19 sq m |
|---|---|
| BassBloc | 300 sq ft, about 28 sq m |
| Bass traps | 10 pieces |
A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels.
06 / Straight talk
Where this goes wrong, said plainly
-
The wrong product for the problem
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.
-
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.

How it looks once it is installed
Japan: questions we are actually asked
Is there a Japan factory behind this product?
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 will acoustic foam and BassBloc not do?
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
Is there a minimum order, and how does it arrive?
The same minimums apply on export. Acoustic foam, 200 sq ft, about 19 sq m. BassBloc, 300 sq ft, about 28 sq m. Bass traps, 10 pieces. A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels. Compressed and boxed for foam, palletised flat for BassBloc.
