Office acoustics and soundproofing in Mumbai
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. 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.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

01 / What it is
The material, and what it actually does on a Mumbai job
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
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 Mumbai is mostly recording studios, offices, flats and redevelopment towers, restaurants, clinics, schools.
- Every centimetre is paid for At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
- The studio capital More recording and dubbing rooms per square kilometre than anywhere else we supply. They sit inside occupied buildings, so isolation comes before tuning, always.
- Monsoon damp defeats the wrong material PET felt does not absorb moisture, shed fibre or feed mould. Mineral products sag here within a couple of seasons.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in Mumbai.

02 / The build-up
The stack, in the order it is installed
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Mumbai, 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.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 2
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Mumbai, 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.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
-
Layer 3
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Mumbai, schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What we see driving Mumbai briefs
- Every centimetre is paid for
At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
- The studio capital
More recording and dubbing rooms per square kilometre than anywhere else we supply. They sit inside occupied buildings, so isolation comes before tuning, always.
- Monsoon damp defeats the wrong material
PET felt does not absorb moisture, shed fibre or feed mould. Mineral products sag here within a couple of seasons.
- Redevelopment, built fast
Old buildings replaced by towers on tight programmes. Acoustic detail is easy to lose unless it is specified before the slab is poured.
- 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 Mumbai project needs
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
- Acoustic carpet and rugs, 500 x 500 mm
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. More recording and dubbing rooms per square kilometre than anywhere else we supply. They sit inside occupied buildings, so isolation comes before tuning, always.
- Acoustic carpet and rugs, 4 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. PET felt does not absorb moisture, shed fibre or feed mould. Mineral products sag here within a couple of seasons.
- Acoustic carpet and rugs, High density polyester
- Acoustic panels, ASTM C423
- SoundBlanket mass loaded vinyl, 5 x 1.2 m, 6 sq m per roll
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 / Climate
The Mumbai climate decides the material list
Mumbai 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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Worth knowing
Where this kind of project usually fails
-
Lining every wall while leaving the ceiling bare
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating a privacy problem with absorption
Nobody has ever achieved speech privacy with a panel. Privacy needs mass, a sealed head detail and a door that actually closes.
-
Glass cabins specified without a door and head detail
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
Treating it as a generic Mumbai job
At Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
05 / Getting it there
What the route into Mumbai actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three to four days |
| Dispatch | 2 to 4 working days |
| To site | three to four 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 fourteen hundred kilometres, normally three to four days on a dedicated truck.
Questions from Mumbai projects
What makes office acoustics and soundproofing different in Mumbai?
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 Mumbai rates a wall that grows a hundred millimetres into the room costs real money. A dense membrane with a resilient break usually beats a thick framed build-up here.
Where should the budget go first on a Mumbai project?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
Do you have an office or installation team in Mumbai?
No. We manufacture in India and supply into Mumbai. 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 Mumbai site?
made at: Our own plant, Palwal, Haryana, reaches site in: three to four 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?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
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.
