HVAC, plant and machine noise control in Bali
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 everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
- 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 is, and what it changes in a Bali room
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 everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
Work reaching us from Bali is mostly resorts and villas, beach clubs and restaurants, spas, offices, guest rooms.
- Buildings that are only partly enclosed Open pavilions and sliding walls mean there is often no envelope to isolate. The honest answer is treating what is there and telling you what cannot be fixed.
- Beach clubs and neighbours Late trading venues beside villas and other resorts, where containment of low frequency is what keeps the operation on good terms.
- Humidity and salt destroy the wrong material PET felt does not absorb moisture, rot or feed mould. Mineral products sag here within a single season.
- 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 Bali.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Bali, split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 2
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 Bali, places of worship, function halls and community buildings are large hard rooms carrying amplified speech and music.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Bali, classrooms are hard, naturally ventilated and open to corridor and street noise, so absorption alone will not fix intelligibility.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
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 Bali briefs
- Buildings that are only partly enclosed
Open pavilions and sliding walls mean there is often no envelope to isolate. The honest answer is treating what is there and telling you what cannot be fixed.
- Beach clubs and neighbours
Late trading venues beside villas and other resorts, where containment of low frequency is what keeps the operation on good terms.
- Humidity and salt destroy the wrong material
PET felt does not absorb moisture, rot or feed mould. Mineral products sag here within a single season.
- An onward leg to the island
Material arrives and then continues by road or ferry. Tell us and we pack for the second journey.
- Plant and HVAC
Split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms.
04 / Room by room
Space by space, for Bali briefs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Open pavilions and sliding walls mean there is often no envelope to isolate. The honest answer is treating what is there and telling you what cannot be fixed.

In the path
Duct lining, attenuators and lagging on the first run out of the plant. Late trading venues beside villas and other resorts, where containment of low frequency is what keeps the operation on good terms.

At the receiver
Only after the first two, and only for what is left. PET felt does not absorb moisture, rot or feed mould. Mineral products sag here within a single season.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Wood wool acoustic panels, ASTM C-423 and EN ISO 354
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Durability
What the Bali climate rules in and rules out
Bali 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 Bali 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
Where this kind of project usually fails
-
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
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
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 Bali job
Open pavilions and sliding walls mean there is often no envelope to isolate. The honest answer is treating what is there and telling you what cannot be fixed.
05 / Route to site
What the route into Bali actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Surabaya or Benoa, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Surabaya or Benoa |
| 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 Surabaya or Benoa, then road or ferry onward to site. Air freight for samples.
Questions from Bali projects
What makes HVAC, plant and machine noise control different in Bali?
Split units everywhere, with condensers on balconies and light wells that channel noise straight back into bedrooms. Open pavilions and sliding walls mean there is often no envelope to isolate. The honest answer is treating what is there and telling you what cannot be fixed.
Where should the budget go first on a Bali 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 Bali?
No. We manufacture in India and supply into Bali. 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 Bali site?
ships from: Palwal, Haryana, India, arrives at: Surabaya or Benoa, 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.
Next step
Send the drawings, get a straight answer
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
