Manufactured in India, supplied in Hong Kong
SoundBlanket mass loaded vinyl in Hong Kong
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Hong Kong. Made at our own plant in India and shipped straight into Hong Kong, so the container lands where it is needed rather than a road leg away.

We make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.
01 / The material
What this material is and where it earns its place in Hong Kong
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. It is the barrier product, not an absorber, and it is the right answer when the problem is noise passing through a structure.
Work reaching us from Hong Kong is mostly apartments, offices, hotels and dining, clinics, schools, studios.
Very dense reinforced concrete towers with hard floors and minimal separation between units. Impact and airborne noise between flats is constant.
- Wall, decoupled Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
- Floor, floating Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
- Duct and plant wrap Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
- What it will not do Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for SoundBlanket MLV are on the main product page. This page covers what that means for a project in Hong Kong.
02 / Specification
The published figures, unchanged by location
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.

- 4 mmSTC 34, 8.4 kg per sq m. Party walls, floors, plant rooms, the common specification
- 6 mm12.6 kg per sq m. Machine enclosures and low frequency problems
| Density | 2100 kg per cubic metre |
|---|---|
| 2.5 mm | STC 30, 5.25 kg per sq m |
| 4 mm | STC 34, 8.4 kg per sq m |
| 6 mm | 12.6 kg per sq m, STC on request |
| Roll size | 5 x 1.2 m, 6 sq m per roll |

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 / On the ground
What the buildings in Hong Kong do to the specification
- Depth is the expensive part
Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost.
- Concrete towers, live rooms
The structure blocks a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer.
- Plant on every roof and podium
Cooling plant sits within metres of windows in a dense city, so plant noise reaches more people than any single source.
- The port is right here
Direct sea into Hong Kong keeps the chain short and the landed cost predictable.
- The housing stock
Very dense reinforced concrete towers with hard floors and minimal separation between units. Impact and airborne noise between flats is constant.
- The studio and content scene
Studios go into industrial buildings where the neighbouring tenancy and the building plant decide what is achievable.
For a Hong Kong practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Conditions
What the Hong Kong climate rules in and rules out
Hong Kong 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
What the route into Hong Kong actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hong Kong, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Hong Kong |
| Packing | Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters. |
| Lead time | 4 to 7 working days. Full container quantities scheduled against the vessel. |
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 direct into Hong Kong, then a short road run to site. Air freight for samples and urgent quantities.
The same minimums apply on export as on domestic orders.
| 2.5 mm and 4 mm | 10 rolls, 60 sq m |
|---|---|
| 6 mm and other thicknesses | 10 tonnes per thickness |
A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm.
06 / Before you buy
The things worth knowing before you place the order
-
The wrong product for the problem
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.
-
A claim of being local to Hong Kong
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.
Hong Kong: questions we are actually asked
Where are the soundBlanket mass loaded vinyl you supply to Hong Kong actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Hong Kong as the manufacturer rather than through a dealer. Made at our own plant in India and shipped straight into Hong Kong, so the container lands where it is needed rather than a road leg away. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Hong Kong enquiry?
Every millimetre a wall grows into the room is paid for at Hong Kong rates. A dense thin membrane usually beats a thicker framed build-up here on total cost. The structure blocks a great deal already. The problem is hard interiors and impact through slabs rather than airborne transfer. Those two things move the build-up far more than the panel figure does.
Is this the right material for Hong Kong conditions?
Hong Kong 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 quickly can material reach a site in Hong Kong?
ships from: Palwal, Haryana, India, arrives at: Hong Kong, then a short road run 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 will soundBlanket mass loaded vinyl not do?
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
What is the minimum order and how is it packed?
The same minimums apply on export as on domestic orders. 2.5 mm and 4 mm, 10 rolls, 60 sq m. 6 mm and other thicknesses, 10 tonnes per thickness. A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm. Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters.
