HVAC, plant and machine noise control in Ho Chi Minh City
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space. Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
- At source
- Enclosure, barrier or anti vibration mounts at the machine.
- In the path
- Duct lining, attenuators and lagging on the first run out of the plant.
- At the receiver
- Only after the first two, and only for what is left.

What this material is and where it earns its place in Ho Chi Minh City
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space.
Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
Work reaching us from Ho Chi Minh City is mostly tube houses and apartments, towers and offices, manufacturing, hotels, schools, clinics.
- Narrow, deep, shared on both sides The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
- Traffic never stops Constant street noise gets in through openings and glazing. The facade is where the first money should go, not the wall.
- New towers, hard interiors Concrete frames with tile and glass inside. The structure blocks, the room rings.
- At source Enclosure, barrier or anti vibration mounts at the machine.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for HVAC and plant noise control are on the main product page. This page covers what that means for a project in Ho Chi Minh City.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Ho Chi Minh City, split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Ho Chi Minh City, function halls, places of worship and conference rooms are hard volumes carrying amplified speech and music.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 3
Acoustic foam and BassBloc
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. In Ho Chi Minh City, classrooms are hard, naturally ventilated and open to street noise, with large class sizes.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What we see driving Ho Chi Minh City briefs
- Narrow, deep, shared on both sides
The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
- Traffic never stops
Constant street noise gets in through openings and glazing. The facade is where the first money should go, not the wall.
- New towers, hard interiors
Concrete frames with tile and glass inside. The structure blocks, the room rings.
- Tropical humidity all year
PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Plant and HVAC
Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts.
04 / Room by room
Space by space, for Ho Chi Minh City briefs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. Constant street noise gets in through openings and glazing. The facade is where the first money should go, not the wall.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Wood wool acoustic panels, 400 kg per cubic metre
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
At the receiver
Only after the first two, and only for what is left. Concrete frames with tile and glass inside. The structure blocks, the room rings.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
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.
04 / Durability
What the Ho Chi Minh City climate rules in and rules out
Ho Chi Minh City is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is 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 failure we design against here is mould, sagging fabric finishes and swelling in timber.
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.
06 / Worth knowing
Six mistakes that turn into a second fit-out
-
Absorption on the office wall for a plant room problem
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Lagging a duct that is carrying the noise as breakout from the fan
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Ignoring structure borne vibration through the mounts
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Ho Chi Minh City job
The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.

Questions from Ho Chi Minh City projects
What makes HVAC, plant and machine noise control different in Ho Chi Minh City?
Split units with condensers on facades and in narrow gaps between buildings that act as reverberant shafts. The tube house has party walls left and right and an open front onto the street, so noise arrives from three directions at once.
Where should the budget go first on a Ho Chi Minh City project?
At source. Enclosure, barrier or anti vibration mounts at the machine. In the path. Duct lining, attenuators and lagging on the first run out of the plant.
Do you have an office or installation team in Ho Chi Minh City?
No. We manufacture in India and supply into Ho Chi Minh City. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Ho Chi Minh City site?
ships from: Palwal, Haryana, India, arrives at: Cat Lai or Cai Mep, then a short road run into the city, 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 goes wrong most often on this kind of project?
Absorption on the office wall for a plant room problem. Lagging a duct that is carrying the noise as breakout from the fan.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
