HVAC, plant and machine noise control in Ludhiana
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. Agro processing and light engineering plant, with generator sets and machinery close to occupied buildings.
- 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 Ludhiana 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.
Agro processing and light engineering plant, with generator sets and machinery close to occupied buildings.
Work reaching us from Ludhiana is mostly knitting and textile units, workshops, worker areas, offices, showrooms, schools, clinics.
- Industry beside housing Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- Machine noise, all shift Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- Hard halls, no intelligibility Large sheds with steel and concrete surfaces make instructions and alarms hard to understand. Targeted absorption fixes that without touching the machines.
- 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 Ludhiana.
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 Ludhiana, agro processing and light engineering plant, with generator sets and machinery close to occupied buildings.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
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 Ludhiana, 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.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
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 Ludhiana, large school and college campuses in concrete and tile, with halls carrying assembly and performance.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What the buildings in Ludhiana do to the specification
- Industry beside housing
Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- Machine noise, all shift
Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- Hard halls, no intelligibility
Large sheds with steel and concrete surfaces make instructions and alarms hard to understand. Targeted absorption fixes that without touching the machines.
- One to two days by road
A dedicated truck from Palwal, with samples sent ahead so you can check the material before committing.
- Plant and HVAC
Agro processing and light engineering plant, with generator sets and machinery close to occupied buildings.

Where the money goes on a Ludhiana project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- 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
- Acoustic foam and BassBloc, 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. Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Acoustic foam and BassBloc, 100 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. Large sheds with steel and concrete surfaces make instructions and alarms hard to understand. Targeted absorption fixes that without touching the machines.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic foam and BassBloc, 100 to 500 Hz
- 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 / Conditions
Why the climate in Ludhiana changes the material, not the target
Ludhiana 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 Ludhiana project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
Where this kind of project usually fails
-
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
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
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating it as a generic Ludhiana job
Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
05 / Supply
What the route into Ludhiana actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | one to two days |
| Dispatch | 2 to 4 working days |
| To site | one to 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 three hundred and fifty kilometres. Full loads on a dedicated truck, smaller consignments on a shared vehicle.
Questions from Ludhiana projects
What makes HVAC, plant and machine noise control different in Ludhiana?
Agro processing and light engineering plant, with generator sets and machinery close to occupied buildings. Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
Where should the budget go first on a Ludhiana 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 Ludhiana?
No. We manufacture in India and supply into Ludhiana. 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 Ludhiana site?
made at: Our own plant, Palwal, Haryana, reaches site in: one to 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 a plan and a section, get a real build-up
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
