01 / Start here
The product, described honestly, for a Hanoi brief
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing.
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.
- Corner loading Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
- First reflection points Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
- Behind a fabric frame Where the room has to look finished, absorber inside a frame rather than foam on show.
- What it will not do Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for acoustic foam and bass traps are on the main product page. This page covers what that means for a project in Hanoi.
02 / Specification
One specification sheet, the same in every market
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.

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
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.
- 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.
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
Why the climate in Hanoi changes the material, not the target
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.
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
Supply into Hanoi, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Haiphong, then road into Hanoi |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Haiphong |
| Packing | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 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.
Sea freight into Haiphong, then road into Hanoi. Air freight for samples and urgent quantities.
The same minimums apply on export.
| Acoustic foam | 200 sq ft, about 19 sq m |
|---|---|
| BassBloc | 300 sq ft, about 28 sq m |
| Bass traps | 10 pieces |
A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels.
06 / Before you buy
Where this goes wrong, said plainly
-
The wrong product for the problem
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.
-
Suppliers who imply a Hanoi 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.

The material in real interiors
Hanoi: questions we are actually asked
Do you manufacture acoustic foam and BassBloc 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 do you look at first on a Hanoi enquiry?
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.
Where do acoustic foam and BassBloc fail to help?
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
Is there a minimum order, and how does it arrive?
The same minimums apply on export. Acoustic foam, 200 sq ft, about 19 sq m. BassBloc, 300 sq ft, about 28 sq m. Bass traps, 10 pieces. A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels. Compressed and boxed for foam, palletised flat for BassBloc.
