HVAC, plant and machine noise control in Bareilly
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 Bareilly 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 Bareilly is mostly furniture and timber units, colleges, hospitals, offices, auditoriums, banquet halls.
- Saws and sanders High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
- New institutional buildings Concrete and tile put up quickly, with acoustics discovered at handover rather than designed out.
- Dust and workshop conditions PET felt does not shed fibre or hold dust the way soft mineral products do, which matters in a woodworking environment.
- 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 Bareilly.
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 Bareilly, 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.
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 Bareilly, banquet halls, marriage lawns and auditoria are large hard volumes where amplified speech and music run late into the night.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 3
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Bareilly, large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
What the buildings in Bareilly do to the specification
- Saws and sanders
High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
- New institutional buildings
Concrete and tile put up quickly, with acoustics discovered at handover rather than designed out.
- Dust and workshop conditions
PET felt does not shed fibre or hold dust the way soft mineral products do, which matters in a woodworking environment.
- One to two days by road
A dedicated truck from Palwal, with samples 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
Room by room, on a typical Bareilly job
-
At source
Enclosure, barrier or anti vibration mounts at the machine. High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
- 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
- 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. Concrete and tile put up quickly, with acoustics discovered at handover rather than designed out.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic foam and BassBloc, 100 to 500 Hz
-
At the receiver
Only after the first two, and only for what is left. PET felt does not shed fibre or hold dust the way soft mineral products do, which matters in a woodworking environment.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Acoustic foam and BassBloc, 0.85
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 / Durability
The Bareilly climate decides the material list
Bareilly 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.
On a Bareilly 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
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Bareilly job
High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
05 / Supply
How material reaches a Bareilly site
| 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, normally one to two days on a dedicated truck.
Questions from Bareilly projects
What makes HVAC, plant and machine noise control different in Bareilly?
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. High frequency, high level and continuous. Enclosure at the machine changes the exposure, and treating the hall does not.
Where should the budget go first on a Bareilly 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 Bareilly?
No. We manufacture in India and supply into Bareilly. 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 Bareilly 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
Tell us the room, we will tell you the build-up
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.
