Cinema and multiplex soundproofing in Trivandrum
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. Auditoria, church buildings and community halls are 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 material
What this is, and what it changes in a Trivandrum 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.
Auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music.
Work reaching us from Trivandrum is mostly government and institutional buildings, technology park offices, hospitals, colleges, hotels, auditoriums.
- Our longest domestic run Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
- Humidity decides the material PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument.
- Technology park floors Open plans with glass and hard flooring that carry every call across the room.
- 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 Trivandrum.
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 Trivandrum, 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 Trivandrum, auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Trivandrum, schools and colleges are naturally ventilated with open corridors, so absorption alone will not fix intelligibility.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
Architects working in Trivandrum usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / In this market
What decides the build-up in Trivandrum
- Our longest domestic run
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
- Humidity decides the material
PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument.
- Technology park floors
Open plans with glass and hard flooring that carry every call across the room.
- Institutional assembly spaces
Large halls in concrete where speech stops being intelligible well before the room sounds wrong.
- Assembly and performance rooms
Auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music.

Where the money goes on a Trivandrum project
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
- 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 carpet and rugs, High density polyester
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Acoustic carpet and rugs, Felt
-
Plant and projection
Equipment noise into the auditorium, treated at source. Open plans with glass and hard flooring that carry every call across the room.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic panels, ASTM C423
- Acoustic carpet and rugs, 64 sq ft per pack
For a Trivandrum interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Durability
Why the climate in Trivandrum changes the material, not the target
Trivandrum 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.
On a Trivandrum 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
-
A shared service void running across the wall line
A treated wall under a bare hard ceiling gives you a fraction of the reduction you paid for, and the room still sounds wrong.
-
Treating the auditorium to fix bleed from the next screen
This is the one that comes back as a second fit-out rather than a snag.
-
Doors and lobbies specified late and undersized
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 Trivandrum job
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
05 / Getting it there
What the route into Trivandrum actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | six days |
| Dispatch | 2 to 4 working days |
| To site | six 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 six hundred kilometres, normally six days on a dedicated truck. It is the longest domestic run we operate.
Questions from Trivandrum projects
What makes cinema and multiplex soundproofing different in Trivandrum?
Auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music. Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
Where should the budget go first on a Trivandrum 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 Trivandrum?
No. We manufacture in India and supply into Trivandrum. 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 Trivandrum site?
made at: Our own plant, Palwal, Haryana, reaches site in: six 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
Send a plan and a section, get a real build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
