HVAC, plant and machine noise control in Vellore
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.

What you are buying, and what it fixes in Vellore
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 Vellore is mostly teaching hospitals, engineering campuses, lecture theatres, hostels, offices, hotels.
- Clinical privacy Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
- Lecture theatres Large teaching rooms where every seat has to hear clearly, usually in concrete and tile.
- Hostels and residences Students living next to each other and to corridors, where separating detail does the work.
- 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 Vellore.
02 / The build-up
The stack, in the order it is installed
-

Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Vellore, 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.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-

Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Vellore, kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-

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 Vellore, very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
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 Vellore do to the specification
- Clinical privacy
Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
- Lecture theatres
Large teaching rooms where every seat has to hear clearly, usually in concrete and tile.
- Hostels and residences
Students living next to each other and to corridors, where separating detail does the work.
- Five days by road
A long run, confirmed before dispatch, with samples sent ahead of the order.
- 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
What each space in a Vellore project needs
-

At source
Enclosure, barrier or anti vibration mounts at the machine. Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- 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. Large teaching rooms where every seat has to hear clearly, usually in concrete and tile.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- 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. Students living next to each other and to corridors, where separating detail does the work.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic foam and BassBloc, 100 to 500 Hz
- Ceiling baffles and clouds, ASTM C423
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 Vellore changes the material, not the target
Vellore 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.
Where a consultant is already engaged on a Vellore project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Straight talk
Six mistakes that turn into a second fit-out
-
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
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
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating it as a generic Vellore job
Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
05 / Getting it there
Supply into Vellore, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five days |
| Dispatch | 2 to 4 working days |
| To site | five 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 twenty two hundred kilometres, normally five days on a dedicated truck.
Questions from Vellore projects
What makes HVAC, plant and machine noise control different in Vellore?
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. Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
Where should the budget go first on a Vellore 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 Vellore?
No. We manufacture in India and supply into Vellore. 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 Vellore site?
made at: Our own plant, Palwal, Haryana, reaches site in: five 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.
