HVAC, plant and machine noise control in Manesar
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. Dense industrial belts mean compressors, presses, generator sets and blower plant sit close to offices and canteens.
- 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 Manesar 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.
Dense industrial belts mean compressors, presses, generator sets and blower plant sit close to offices and canteens.
Work reaching us from Manesar is mostly automotive and component plants, QC and test rooms, corporate offices, training rooms, canteens.
- Continuous machinery Presses, robots and conveyors run all shift. The fix is enclosure and barrier at the source, not absorption at the far wall.
- Test and measurement rooms NVH and QC rooms need a low background before any measurement means anything. That is isolation work with a written target.
- An hour from the plant Short road run, so samples arrive next day and full loads are cheap to move.
- 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 Manesar.
02 / The build-up
The build-up, layer by layer
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Manesar, dense industrial belts mean compressors, presses, generator sets and blower plant sit close to offices and canteens.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
Layer 2
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 Manesar, auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
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 Manesar, classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
First reflection points. Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
The Manesar conditions that change the answer
- Continuous machinery
Presses, robots and conveyors run all shift. The fix is enclosure and barrier at the source, not absorption at the far wall.
- Test and measurement rooms
NVH and QC rooms need a low background before any measurement means anything. That is isolation work with a written target.
- An hour from the plant
Short road run, so samples arrive next day and full loads are cheap to move.
- Training and briefing rooms
Rooms where instructions have to be understood over plant noise need intelligibility, not just less echo.
- Plant and HVAC
Dense industrial belts mean compressors, presses, generator sets and blower plant sit close to offices and canteens.
04 / Room by room
Room by room, on a typical Manesar job
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Presses, robots and conveyors run all shift. The fix is enclosure and barrier at the source, not absorption at the far wall.
- 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
- Wood wool acoustic panels, 400 kg per cubic metre
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. NVH and QC rooms need a low background before any measurement means anything. That is isolation work with a written target.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Wood wool acoustic panels, 0.30
-
At the receiver
Only after the first two, and only for what is left. Short road run, so samples arrive next day and full loads are cheap to move.
- 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
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 / Climate and durability
Why the climate in Manesar changes the material, not the target
Manesar is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
Where a consultant is already engaged on a Manesar project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Read this first
Where this kind of project usually fails
-
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 Manesar job
Presses, robots and conveyors run all shift. The fix is enclosure and barrier at the source, not absorption at the far wall.
05 / Supply
Getting it to Manesar, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | a day |
| Dispatch | 2 to 4 working days |
| To site | a day |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
Same day or next day by road from Palwal. Small consignments go on a shared vehicle, full loads on a dedicated truck.
Questions from Manesar projects
What makes HVAC, plant and machine noise control different in Manesar?
Dense industrial belts mean compressors, presses, generator sets and blower plant sit close to offices and canteens. Presses, robots and conveyors run all shift. The fix is enclosure and barrier at the source, not absorption at the far wall.
Where should the budget go first on a Manesar 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 Manesar?
No. We manufacture in India and supply into Manesar. 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 Manesar site?
made at: Our own plant, Palwal, Haryana, reaches site in: a day, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. 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 a plan and a section, get a real build-up
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.
