HVAC, plant and machine noise control in Pune
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, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
- 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 product, described honestly, for a Pune 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, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
Work reaching us from Pune is mostly automotive and engineering plants, townships and apartment towers, IT offices, colleges, clinics.
- Machinery, not conversation Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
- New townships, repeated details The same separating wall across hundreds of flats. Getting it right on the drawing is far cheaper than fixing it after possession.
- Education and test rooms Colleges and engineering centres with rooms that need a genuinely low background before measurement means anything.
- 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 Pune.
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 Pune, split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Pune, 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.
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 Pune, schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
Architects working in Pune 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 / On the ground
What we see driving Pune briefs
- Machinery, not conversation
Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
- New townships, repeated details
The same separating wall across hundreds of flats. Getting it right on the drawing is far cheaper than fixing it after possession.
- Education and test rooms
Colleges and engineering centres with rooms that need a genuinely low background before measurement means anything.
- Monsoon damp
PET felt does not absorb moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Plant and HVAC
Split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
04 / Room by room
Space by space, for Pune briefs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
- 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. The same separating wall across hundreds of flats. Getting it right on the drawing is far cheaper than fixing it after possession.
- 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. Colleges and engineering centres with rooms that need a genuinely low background before measurement means anything.
- 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
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate
Durability in Pune, before acoustics is discussed
Pune 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.
On a Pune job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

What we watch go wrong on jobs like this
-
Absorption on the office wall for a plant room problem
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
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 Pune job
Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
05 / Getting it there
What the route into Pune actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three to four days |
| Dispatch | 2 to 4 working days |
| To site | three to four days |
| 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.
By road from Palwal, roughly fourteen hundred kilometres, normally three to four days on a dedicated truck.
Questions from Pune projects
What makes HVAC, plant and machine noise control different in Pune?
Split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs. Presses, compressors and test rigs are low frequency and structure-borne. Enclosure at the source is the only thing that addresses them.
Where should the budget go first on a Pune 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 Pune?
No. We manufacture in India and supply into Pune. 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 Pune site?
made at: Our own plant, Palwal, Haryana, reaches site in: three to four days, 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
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.
