HVAC, plant and machine noise control in Ahmedabad
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. Heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building.
- 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.

What you are buying, and what it fixes in Ahmedabad
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.
Heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building.
Work reaching us from Ahmedabad is mostly textile and processing units, institutional buildings, offices, auditoriums, schools, hospitals.
- Dry heat PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- Textile machinery runs all shift Continuous machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
- Ambitious new buildings Exposed concrete and brick used as the finish, which looks superb and reflects almost everything. Absorption has to go where it will not fight the architecture.
- 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 Ahmedabad.
02 / The build-up
How the layers stack, from the structure inwards
-
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 Ahmedabad, heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building.
Independent leaf. A second wall that does not touch the first. Nothing else comes close for the money.
-
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 Ahmedabad, 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.
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 Ahmedabad, large school and college campuses in concrete and tile, with assembly halls and auditoria in constant use.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
For a Ahmedabad practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

What decides the build-up in Ahmedabad
- Dry heat
PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- Textile machinery runs all shift
Continuous machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
- Ambitious new buildings
Exposed concrete and brick used as the finish, which looks superb and reflects almost everything. Absorption has to go where it will not fight the architecture.
- Two days from the plant
A short run by Indian standards, so freight is cheap and samples arrive quickly.
- Plant and HVAC
Heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building.

Where the money goes on a Ahmedabad project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
- Wood wool acoustic panels, 20 mm
- Acoustic foam and BassBloc, 100 kg per cubic metre
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. Continuous machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
- 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
- Acoustic foam and BassBloc, 100 to 500 Hz
-
At the receiver
Only after the first two, and only for what is left. Exposed concrete and brick used as the finish, which looks superb and reflects almost everything. Absorption has to go where it will not fight the architecture.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Wood wool acoustic panels, 0.30
- Acoustic foam and BassBloc, 0.85
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
Durability in Ahmedabad, before acoustics is discussed
Ahmedabad is hot and dry for most of the year, with dust and high daytime surface temperatures, and that narrows the material list before acoustics is discussed.
Dust is the enemy of open-cell products. PET felt does not shed, does not hold dust in the way fabric-wrapped glass wool does, and wipes down. Timber needs a stable indoor RH or it moves.
The failure we design against here is dust ingress and thermal movement in long runs.
Where a consultant is already engaged on a Ahmedabad project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Straight talk
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Ahmedabad job
PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
05 / Supply
Getting it to Ahmedabad, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two days |
| Dispatch | 2 to 4 working days |
| To site | two 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 nine hundred kilometres, normally two days on a dedicated truck.
Questions from Ahmedabad projects
What makes HVAC, plant and machine noise control different in Ahmedabad?
Heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building. Continuous machine noise in units that often sit close to housing. Enclosure and barrier at the source, not lining the hall.
Where should the budget go first on a Ahmedabad 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 Ahmedabad?
No. We manufacture in India and supply into Ahmedabad. 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 Ahmedabad site?
made at: Our own plant, Palwal, Haryana, reaches site in: two 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 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.
