HVAC, plant and machine noise control in Bangkok
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 and VRF with condensers on balconies and in light wells, running at full load most of the year.
- 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 / The material
What this material is and where it earns its place in Bangkok
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 and VRF with condensers on balconies and in light wells, running at full load most of the year.
Work reaching us from Bangkok is mostly condo towers, hotels and lounges, offices, restaurants, clinics, studios.
- Heat and humidity all year Our PET felt does not hold moisture or feed mould, which matters where mineral products sag in a tropical climate.
- Concrete towers, live interiors The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- Elevated rail and traffic Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- 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 Bangkok.
02 / The build-up
The stack, in the order it is installed
-
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 Bangkok, split units and VRF with condensers on balconies and in light wells, running at full load most of the year.
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 Bangkok, temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Bangkok, classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
Architects working in Bangkok usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / In this market
What the buildings in Bangkok do to the specification
- Heat and humidity all year
Our PET felt does not hold moisture or feed mould, which matters where mineral products sag in a tropical climate.
- Concrete towers, live interiors
The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- Elevated rail and traffic
Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- Impact through slabs
Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix.
- Plant and HVAC
Split units and VRF with condensers on balconies and in light wells, running at full load most of the year.
04 / Room by room
What each space in a Bangkok project needs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Our PET felt does not hold moisture or feed mould, which matters where mineral products sag in a tropical climate.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic foam and BassBloc, 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. The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic foam and BassBloc, 100 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. Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic foam and BassBloc, 100 to 500 Hz
- 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 / Conditions
Why the climate in Bangkok changes the material, not the target
Bangkok 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 Bangkok 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
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
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
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 Bangkok job
Our PET felt does not hold moisture or feed mould, which matters where mineral products sag in a tropical climate.
05 / Route to site
How material reaches a Bangkok site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Laem Chabang, then a short road run into Bangkok |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Laem Chabang |
| 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 Laem Chabang, then a short road run into Bangkok. Air freight for samples and urgent quantities.
Questions from Bangkok projects
What makes HVAC, plant and machine noise control different in Bangkok?
Split units and VRF with condensers on balconies and in light wells, running at full load most of the year. The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
Where should the budget go first on a Bangkok 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 Bangkok?
No. We manufacture in India and supply into Bangkok. 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 Bangkok site?
ships from: Palwal, Haryana, India, arrives at: Laem Chabang, then a short road run into Bangkok, 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.
Next step
Tell us the room, we will tell you the build-up
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
