Office acoustics and soundproofing in China
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. Central plant, VRF and split units, with risers and duct runs carrying noise between floors.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

01 / What it is
The material, and what it actually does on a China job
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
Central plant, VRF and split units, with risers and duct runs carrying noise between floors.
Work reaching us from China is mostly specification-led projects, international hotel and office fit-out, studios, showrooms.
- We are not the default here Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
- Concrete towers, hard interiors The structure blocks well, so the recurring problems are live rooms and impact passing down through slabs.
- Colour across a large order Where a single project runs across many floors, batch to batch consistency is usually the reason people come to a single manufacturer.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in China.

02 / The build-up
What goes where, from the structure in
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In China, central plant, VRF and split units, with risers and duct runs carrying noise between floors.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In China, auditoria, conference centres and function halls are large hard volumes with long decay.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In China, school buildings are concrete and tile with very large class sizes and long hard corridors.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
Architects working in China usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / On the ground
What we see driving China briefs
- We are not the default here
Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
- Concrete towers, hard interiors
The structure blocks well, so the recurring problems are live rooms and impact passing down through slabs.
- Colour across a large order
Where a single project runs across many floors, batch to batch consistency is usually the reason people come to a single manufacturer.
- Well served ports
Shanghai, Ningbo and Shenzhen all run frequently from India, so routing is straightforward.
- Plant and HVAC
Central plant, VRF and split units, with risers and duct runs carrying noise between floors.
04 / Room by room
Space by space, for China briefs
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. The structure blocks well, so the recurring problems are live rooms and impact passing down through slabs.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. Where a single project runs across many floors, batch to batch consistency is usually the reason people come to a single manufacturer.
- PET felt acoustic panels, 4 to 24 mm
- Acoustic panels, ASTM C423
- SoundBlanket mass loaded vinyl, 5 x 1.2 m, 6 sq m per roll
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 China climate rules in and rules out
China 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.
Where a consultant is already engaged on a China project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Before you buy
The six errors that cost the most
-
Lining every wall while leaving the ceiling bare
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating a privacy problem with absorption
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.
-
Glass cabins specified without a door and head detail
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating it as a generic China job
Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
05 / Logistics
How material reaches a China site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Shanghai, Ningbo or Shenzhen, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Shanghai or Ningbo |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
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 Shanghai, Ningbo or Shenzhen, then road to site. Air freight for samples and urgent quantities.
Questions from China projects
What makes office acoustics and soundproofing different in China?
Central plant, VRF and split units, with risers and duct runs carrying noise between floors. Domestic supply is abundant and competitive. We are worth importing when the specification, the colour consistency or the supply chain is the reason, not the price.
Where should the budget go first on a China project?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
Do you have an office or installation team in China?
No. We manufacture in India and supply into China. 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 China site?
ships from: Palwal, Haryana, India, arrives at: Shanghai, Ningbo or Shenzhen, then road to site, 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.
What goes wrong most often on this kind of project?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
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.
Next step
Tell us the room, we will tell you the build-up
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
