Manufactured in India, supplied in Seoul
SoundBlanket mass loaded vinyl in Seoul
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Seoul. Made at our own plant in India and shipped into Incheon, close to the city, so the road leg after the port is short.

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 / Start here
The product, described honestly, for a Seoul brief
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 Seoul is mostly apartment towers, offices, studios and content rooms, cafes and dining, clinics, schools.
Reinforced concrete apartment towers with underfloor heating and hard floors. Impact noise between floors is the single biggest residential complaint.
- 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 Seoul.
02 / Specification
The numbers, and they do not move by city
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- 2.5 mmSTC 30, 5.25 kg per sq m. Ducts, light partitions, retrofit where depth is tight
- 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 |
| Form | Limp sheet, cuts with a knife, seams lapped and sealed |
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
03 / In this market
What the buildings in Seoul do to the specification
- Content rooms everywhere
Studios, streaming rooms and practice spaces inside residential and commercial towers. Isolation from the building is what makes them usable.
- It is the floor, not the wall
Impact noise from above dominates complaints in this city. The fix goes under the finish before the finish goes down, not on the ceiling afterwards.
- Dense, vertical, mixed use
Cafes and venues sit underneath homes in the same structure, so containment decides trading hours.
- Incheon is close
A short road leg after the port keeps landed cost and dates predictable.
- The housing stock
Reinforced concrete apartment towers with underfloor heating and hard floors. Impact noise between floors is the single biggest residential complaint.
- The studio and content scene
A very large music and content industry with rooms built inside commercial buildings to measured targets.
If you are specifying for a Seoul project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate and durability
Why the climate in Seoul changes the material, not the target
Seoul 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 / Getting it there
How material reaches a Seoul site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Incheon, then a short road run into Seoul |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Incheon |
| 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 into Incheon, then a short road run into Seoul. 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.

Suppliers who imply a Seoul presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Seoul: questions we are actually asked
Is there a Seoul 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 Seoul as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Incheon, close to the city, so the road leg after the port is short. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Seoul project?
Impact noise from above dominates complaints in this city. The fix goes under the finish before the finish goes down, not on the ceiling afterwards. Studios, streaming rooms and practice spaces inside residential and commercial towers. Isolation from the building is what makes them usable. Those two things move the build-up far more than the panel figure does.
Is this the right material for Seoul conditions?
Seoul 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.
When would material land on a Seoul site?
ships from: Palwal, Haryana, India, arrives at: Incheon, then a short road run into Seoul, 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 quantity do we have to order, and in what packaging?
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.
