Manufactured in India, supplied in Hanoi
Soundproofing materials in Hanoi
We manufacture soundproofing materials 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.

- One batch across the order, no blending between runs
We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / Start here
What this material is and where it earns its place in Hanoi
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
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.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in Hanoi.

02 / The numbers
One specification sheet, the same in every market
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.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

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 / What drives the brief
The Hanoi conditions that change the answer
- 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.
- Plant and HVAC
Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
- The housing stock
Tube houses and apartment towers in concrete and block, sharing walls with neighbours on both sides and hard floors throughout.
Architects working in Hanoi usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Climate and durability
Durability in Hanoi, before acoustics is discussed
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.
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 / Getting it there
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, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.
06 / Before you buy
The things worth knowing before you place the order
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.
-
A claim of being local to Hanoi
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.

The material in real interiors
Hanoi: questions we are actually asked
Do you manufacture soundproofing materials 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.
Why would a Hanoi build-up differ from anywhere else?
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.
How quickly can material reach a site in Hanoi?
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 will soundproofing materials not do?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
Is there a minimum order, and how does it arrive?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.

Send a plan and a section, get a real build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
