For projects in Japan
Hospital and healthcare acoustics in Japan
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed. Split units and VRF with outdoor units in very tight gaps between buildings.
- Consulting room privacy
- Speech privacy between rooms, which is partition, door and ceiling void work.
- Ward noise floor
- Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
- Cleanability
- Non shedding, non absorbent surfaces that survive a cleaning regime.

01 / What it is
The product, described honestly, for a Japan brief
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed.
Split units and VRF with outdoor units in very tight gaps between buildings.
Work reaching us from Japan is mostly apartments and houses, offices, studios, hotels, schools, clinics.
- 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.
- Consulting room privacy Speech privacy between rooms, which is partition, door and ceiling void work.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for healthcare acoustics are on the main product page. This page covers what that means for a project in Japan.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Japan, split units and VRF with outdoor units in very tight gaps between buildings.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Japan, halls, temples and civic auditoria range from very controlled to very reverberant, and both need measured targets.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Japan, school buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
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.
03 / On the ground
What we see driving Japan briefs
- 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.
- Plant and HVAC
Split units and VRF with outdoor units in very tight gaps between buildings.
04 / Room by room
Space by space, for Japan briefs
-
Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. Depth is genuinely scarce, so a thin build-up that performs is worth more than a thicker one that performs marginally better.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Ward noise floor
Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling. Seismic detailing means junctions that must stay flexible. An acoustic layer cannot bridge a movement joint rigidly.
- Ceiling baffles and clouds, 9 to 24 mm
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic panels, ASTM C423
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. Specifications here are written carefully and checked properly. Send us the target and we will say plainly what our material reaches.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
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.
04 / 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 material list before acoustics is 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 failure we design against here is wet-season humidity behind linings.
On a Japan job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
Six mistakes that turn into a second fit-out
-
Fabric wrapped products in a clinical area
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
Absorption used where privacy was the requirement
If the complaint is being overheard, no amount of absorption inside the room will fix it. That is a partition job and we will say so.
-
Ceiling void left open above a partition
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating it as a generic Japan job
Depth is genuinely scarce, so a thin build-up that performs is worth more than a thicker one that performs marginally better.
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 |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
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.
Questions from Japan projects
What makes hospital and healthcare acoustics different in Japan?
Split units and VRF with outdoor units in very tight gaps between buildings. Depth is genuinely scarce, so a thin build-up that performs is worth more than a thicker one that performs marginally better.
Where should the budget go first on a Japan project?
Consulting room privacy. Speech privacy between rooms, which is partition, door and ceiling void work. Ward noise floor. Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
Do you have an office or installation team in Japan?
No. We manufacture in India and supply into Japan. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Japan site?
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 goes wrong most often on this kind of project?
Fabric wrapped products in a clinical area. Absorption used where privacy was the requirement.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.

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.
