HVAC, plant and machine noise control in Cambodia
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.
- 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.

01 / What it is
The material, and what it actually does on a Cambodia job
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.
Work reaching us from Cambodia is mostly garment and manufacturing units, hotels, offices, schools, hospitals, restaurants.
- Generators are part of the building Standby generation runs often enough to be a permanent condition and sits close to occupied space. Enclosure at the source is the only real fix.
- Garment floors at scale Large production halls with continuous machine noise and rooms where instructions and alarms must be understood.
- Tropical humidity PET felt does not hold moisture or feed mould, which decides whether a ceiling survives more than a couple of seasons.
- 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 Cambodia.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Cambodia, split units with condensers on facades and in narrow gaps between buildings.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Cambodia, temples, function halls and conference rooms are hard volumes carrying amplified speech.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
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 Cambodia, classrooms are hard and naturally ventilated, open to street and corridor noise.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
If you are specifying for a Cambodia project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What the buildings in Cambodia do to the specification
- Generators are part of the building
Standby generation runs often enough to be a permanent condition and sits close to occupied space. Enclosure at the source is the only real fix.
- Garment floors at scale
Large production halls with continuous machine noise and rooms where instructions and alarms must be understood.
- Tropical humidity
PET felt does not hold moisture or feed mould, which decides whether a ceiling survives more than a couple of seasons.
- Hospitality in heritage towns
Hotel work where guest room isolation and function room acoustics are the recurring briefs.
- Plant and HVAC
Split units with condensers on facades and in narrow gaps between buildings.
04 / Room by room
Room by room, on a typical Cambodia job
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Standby generation runs often enough to be a permanent condition and sits close to occupied space. Enclosure at the source is the only real fix.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- 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. Large production halls with continuous machine noise and rooms where instructions and alarms must be understood.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- 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. PET felt does not hold moisture or feed mould, which decides whether a ceiling survives more than a couple of seasons.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Ceiling baffles and clouds, ASTM C423
For a Cambodia interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate and durability
Durability in Cambodia, before acoustics is discussed
Cambodia 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.
Where a consultant is already engaged on a Cambodia project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Before you buy
What we watch go wrong on jobs like this
-
Absorption on the office wall for a plant room problem
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Cambodia job
Standby generation runs often enough to be a permanent condition and sits close to occupied space. Enclosure at the source is the only real fix.
05 / Route to site
What the route into Cambodia actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Sihanoukville, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Sihanoukville |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
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 Sihanoukville, then road to site. Air freight for samples and urgent quantities.
Questions from Cambodia projects
What makes HVAC, plant and machine noise control different in Cambodia?
Split units with condensers on facades and in narrow gaps between buildings. Standby generation runs often enough to be a permanent condition and sits close to occupied space. Enclosure at the source is the only real fix.
Where should the budget go first on a Cambodia 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 Cambodia?
No. We manufacture in India and supply into Cambodia. 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 Cambodia site?
ships from: Palwal, Haryana, India, arrives at: Sihanoukville, then road to site, 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.
