HVAC, plant and machine noise control in Rajkot
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.

01 / The material
What this is, and what it changes in a Rajkot 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.
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 Rajkot is mostly foundries and machining halls, engineering units, offices, colleges, hospitals, showrooms.
- Heat inside the building PET felt does not sag, shed fibre or degrade at high temperature, which matters in a foundry roof void.
- Foundry noise is structural Furnaces, hammers and heavy machine tools put energy into the floor. Isolation and mass address that, and absorption does not.
- Machining halls Continuous machine noise where instructions and alarms still have to be understood. Targeted absorption fixes intelligibility.
- 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 Rajkot.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Rajkot, heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
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 Rajkot, 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 Rajkot, 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.
If you are specifying for a Rajkot project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / Local conditions
The Rajkot conditions that change the answer
- Heat inside the building
PET felt does not sag, shed fibre or degrade at high temperature, which matters in a foundry roof void.
- Foundry noise is structural
Furnaces, hammers and heavy machine tools put energy into the floor. Isolation and mass address that, and absorption does not.
- Machining halls
Continuous machine noise where instructions and alarms still have to be understood. Targeted absorption fixes intelligibility.
- Two to three days by road
A dedicated truck from Palwal, with samples sent ahead of the order.
- 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.
04 / Room by room
Room by room, on a typical Rajkot job
-
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 a foundry roof void.
- 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. Furnaces, hammers and heavy machine tools put energy into the floor. Isolation and mass address that, and absorption does not.
- 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. Continuous machine noise where instructions and alarms still have to be understood. Targeted absorption fixes intelligibility.
- 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
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
Durability in Rajkot, before acoustics is discussed
Rajkot 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.
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 Rajkot job
PET felt does not sag, shed fibre or degrade at high temperature, which matters in a foundry roof void.
05 / Route to site
What the route into Rajkot actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two to three days |
| Dispatch | 2 to 4 working days |
| To site | two to three 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 one thousand kilometres, normally two to three days on a dedicated truck.
Questions from Rajkot projects
What makes HVAC, plant and machine noise control different in Rajkot?
Heavy industrial plant across the state, so compressors, presses and generator sets sit close to offices and canteens inside the same building. Furnaces, hammers and heavy machine tools put energy into the floor. Isolation and mass address that, and absorption does not.
Where should the budget go first on a Rajkot 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 Rajkot?
No. We manufacture in India and supply into Rajkot. 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 Rajkot site?
made at: Our own plant, Palwal, Haryana, reaches site in: two to three 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
Tell us the room, we will tell you the 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.
