Manufactured in India, supplied in Hanoi
SoundBlanket mass loaded vinyl in Hanoi
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Hanoi. Made at our own plant in India and shipped into Haiphong, then road into the city, with the inland leg written into the dates we quote.

This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / The material
What this is, and what it changes in a Hanoi room
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 Hanoi is mostly manufacturing plants, tube houses and apartments, offices, hotels, schools, clinics.
Tube houses and apartment towers in concrete and block, sharing walls with neighbours on both sides and hard floors throughout.
- 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 Hanoi.
02 / Data sheet
One specification sheet, the same in every market
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- 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

On a Hanoi job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
What the buildings in Hanoi do to the specification
- Narrow, deep buildings
The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides.
- Continuous street noise
Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first.
- New manufacturing at pace
Plants going up quickly on greenfield sites, where enclosure and partition detail can still be designed in.
- Hot, humid, monsoon
PET felt does not absorb moisture or feed mould, which matters where mineral products sag in a couple of seasons.
- The housing stock
Tube houses and apartment towers in concrete and block, sharing walls with neighbours on both sides and hard floors throughout.
- The studio and content scene
A fast growing content scene works out of rooms in tube houses and commercial floors with thin partitions.
For a Hanoi 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 Hanoi climate rules in and rules out
Hanoi is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The risk we design against here is mould, sagging fabric finishes and swelling in timber.
For a Hanoi interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
How material reaches a Hanoi site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Haiphong, then road into Hanoi |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Haiphong |
| 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 Haiphong, then road into Hanoi. 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.
-
Local approvals that nobody actually holds
We hold no Hanoi certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Hanoi: questions we are actually asked
Are these soundBlanket mass loaded vinyl made in Hanoi?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Hanoi as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Haiphong, then road into the city, with the inland leg written into the dates we quote. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Hanoi project?
The classic tube house is long and narrow with party walls on both sides and an open front onto the street. Noise comes from the front and through both sides. Traffic is relentless and close. It gets in through openings and glazing, so the facade path is where the money should go first. Those two things move the build-up far more than the panel figure does.
Does Hanoi weather shorten the life of this material?
Hanoi is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.
When would material land on a Hanoi site?
ships from: Palwal, Haryana, India, arrives at: Haiphong, then road into Hanoi, 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 should you not buy soundBlanket mass loaded vinyl for?
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.

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.
