Cinema and multiplex soundproofing in Chennai
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes. Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
- Screen to screen
- Independent construction between auditoria, with services broken at the line.
- In room response
- Heavy absorption on side and rear walls so the mix is heard as intended.
- Plant and projection
- Equipment noise into the auditorium, treated at source.

01 / The product
What this is, and what it changes in a Chennai room
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes.
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
Work reaching us from Chennai is mostly IT corridor offices, automotive plants, recording and dubbing rooms, hospitals, schools, hotels.
- Salt air and humidity PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
- Automotive plants Presses, conveyors and test rooms where the answer is enclosure and mass rather than absorption on a far wall.
- Dubbing and recording rooms A long established film sound industry, mostly in rooms inside occupied buildings. Isolation first, tuning second.
- Screen to screen Independent construction between auditoria, with services broken at the line.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for cinema soundproofing are on the main product page. This page covers what that means for a project in Chennai.
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 Chennai, 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.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
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 Chennai, kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
Independent leaf. A second wall that does not touch the first. Nothing else comes close for the money.
-
Layer 3
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Chennai, very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
If you are specifying for a Chennai project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / On the ground
What decides the build-up in Chennai
- Salt air and humidity
PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
- Automotive plants
Presses, conveyors and test rooms where the answer is enclosure and mass rather than absorption on a far wall.
- Dubbing and recording rooms
A long established film sound industry, mostly in rooms inside occupied buildings. Isolation first, tuning second.
- Sealed against the heat
Rooms stay closed and conditioned for most of the year, so sound builds up inside instead of leaking away.
- Assembly and performance rooms
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.

What each space in a Chennai project needs
-
Screen to screen
Independent construction between auditoria, with services broken at the line. PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
- Acoustic carpet and rugs, 4 mm
- PET felt acoustic panels, 4 to 24 mm
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Presses, conveyors and test rooms where the answer is enclosure and mass rather than absorption on a far wall.
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Acoustic carpet and rugs, High density polyester
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Plant and projection
Equipment noise into the auditorium, treated at source. A long established film sound industry, mostly in rooms inside occupied buildings. Isolation first, tuning second.
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Acoustic carpet and rugs, Felt
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
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
The Chennai climate decides the material list
Chennai 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 Chennai project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
Six mistakes that turn into a second fit-out
-
A shared service void running across the wall line
Square metre for square metre the ceiling is the cheapest result in the room. Skipping it and buying wall panels instead is the most common way to overspend.
-
Treating the auditorium to fix bleed from the next screen
Small on the drawing, expensive on site, and almost always found after handover.
-
Doors and lobbies specified late and undersized
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating it as a generic Chennai job
PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
05 / Route to site
Supply into Chennai, 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 Chennai projects
What makes cinema and multiplex soundproofing different in Chennai?
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music. PET felt does not absorb moisture, rot or feed mould. On a coastal site that is the difference between a ceiling that lasts and one that sags in two monsoons.
Where should the budget go first on a Chennai project?
Screen to screen. Independent construction between auditoria, with services broken at the line. In room response. Heavy absorption on side and rear walls so the mix is heard as intended.
Do you have an office or installation team in Chennai?
No. We manufacture in India and supply into Chennai. 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 Chennai 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?
A shared service void running across the wall line. Treating the auditorium to fix bleed from the next screen.
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
Drawings in, BOQ and a delivered date out
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.
