Soundproof curtains in Japan

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 / Start here
The material, and what it actually does on a Japan job
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. It is the answer for a doorway, a stage, a partition that must move, not a substitute for a wall.
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.
- Full height with return Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
- Track with a seal Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
- Double layer at a doorway Two curtains with an air gap where a single layer will not reach the target.
- What it will not do A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for soundproof curtains are on the main product page. This page covers what that means for a project in Japan.
02 / Specification sheet
Published specification, identical wherever we ship it
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.

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.
- 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.
Architects working in Japan 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 and durability
What the Japan climate rules in and rules out
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 / Getting it there
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 | Rolled and bagged with track and fixings listed separately. |
| Lead time | Made to size. Confirmed at quote. |
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 5 piece minimum applies on export.
| Any size | 5 pieces |

Curtains are made to size, so the minimum is counted in pieces rather than area.
06 / Before you buy
The things worth knowing before you place the order
-
The wrong product for the problem
A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet. We quote the detail, not just the fabric.
-
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.
-
A claim of being local to Japan
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.
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.
What is the delivery time into 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.
Where do soundproof curtains fail to help?
A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet. We quote the detail, not just the fabric.
What quantity do we have to order, and in what packaging?
The same 5 piece minimum applies on export. Any size, 5 pieces. Curtains are made to size, so the minimum is counted in pieces rather than area. Rolled and bagged with track and fixings listed separately.
Next step
Tell us the room, we will tell you the build-up
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
