HVAC, plant and machine noise control in Manila
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 running at full load year round, with condensers close to occupied rooms.
- 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.
- Quote
- From a plan and a section, within 48 hours

The product, described honestly, for a Manila brief
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 running at full load year round, with condensers close to occupied rooms.
Work reaching us from Manila is mostly service and call centre floors, offices, condominium towers, hotels, hospitals, schools.
- Hundreds of simultaneous conversations A call floor is not an echo problem. Absorption alone will not deliver privacy or intelligibility, so ceiling, screens and layout have to work together.
- Concrete towers, hard interiors The structure blocks well. The problem is tile and glass making the room ring, and impact passing down through slabs.
- Typhoon season and humidity PET felt does not absorb moisture, rot or feed mould, which matters where mineral products sag within a 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 Manila.
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 Manila, split units and VRF running at full load year round, with condensers close to occupied rooms.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Manila, church buildings, gymnasiums and function halls carry amplified speech and music in hard volumes.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Manila, classrooms are hard and naturally ventilated with very large class sizes and open corridors.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
Architects working in Manila 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 / Local conditions
What decides the build-up in Manila
- Hundreds of simultaneous conversations
A call floor is not an echo problem. Absorption alone will not deliver privacy or intelligibility, so ceiling, screens and layout have to work together.
- Concrete towers, hard interiors
The structure blocks well. The problem is tile and glass making the room ring, and impact passing down through slabs.
- Typhoon season and humidity
PET felt does not absorb moisture, rot or feed mould, which matters where mineral products sag within a season.
- Traffic outside, all day
Street noise reaches rooms through glazing rather than walls, so the facade is where the first money should go.
- Plant and HVAC
Split units and VRF running at full load year round, with condensers close to occupied rooms.
04 / Room by room
Where the money goes on a Manila project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. A call floor is not an echo problem. Absorption alone will not deliver privacy or intelligibility, so ceiling, screens and layout have to work together.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- 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. The structure blocks well. The problem is tile and glass making the room ring, and impact passing down through slabs.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- 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. PET felt does not absorb moisture, rot or feed mould, which matters where mineral products sag within a season.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
For a Manila interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Durability
What the Manila climate rules in and rules out
Manila 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 / Straight talk
The six errors that cost the most
-
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 Manila job
A call floor is not an echo problem. Absorption alone will not deliver privacy or intelligibility, so ceiling, screens and layout have to work together.
05 / Route to site
How material reaches a Manila site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Manila, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Manila |
| 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 Manila, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Manila projects
What makes HVAC, plant and machine noise control different in Manila?
Split units and VRF running at full load year round, with condensers close to occupied rooms. A call floor is not an echo problem. Absorption alone will not deliver privacy or intelligibility, so ceiling, screens and layout have to work together.
Where should the budget go first on a Manila 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 Manila?
No. We manufacture in India and supply into Manila. 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 Manila site?
ships from: Palwal, Haryana, India, arrives at: Manila, then a short road run 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.

Send the drawings, get a straight answer
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
