Cinema and multiplex soundproofing in Port Blair
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. Community halls, church buildings and resort function rooms are hard volumes carrying amplified speech.
- 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 material is and where it earns its place in Port Blair
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.
Community halls, church buildings and resort function rooms are hard volumes carrying amplified speech.
Work reaching us from Port Blair is mostly hotels and guest houses, administrative buildings, hospitals, schools, dining spaces, offices.
- The sailing sets the date Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date.
- Get it right the first time A replacement means waiting for the next sailing. We confirm the specification and send samples before anything ships.
- Salt air and heavy monsoon PET felt does not absorb moisture, rot or corrode, which matters where almost everything else degrades quickly.
- 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 Port Blair.
02 / The build-up
What goes where, from the structure in
-
Layer 1
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 Port Blair, 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.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
Layer 2
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Port Blair, community halls, church buildings and resort function rooms are hard volumes carrying amplified speech.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Port Blair, classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
For a Port Blair practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / On the ground
What the buildings in Port Blair do to the specification
- The sailing sets the date
Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date.
- Get it right the first time
A replacement means waiting for the next sailing. We confirm the specification and send samples before anything ships.
- Salt air and heavy monsoon
PET felt does not absorb moisture, rot or corrode, which matters where almost everything else degrades quickly.
- Seismic islands
Buildings are designed to move, so a build-up must not stiffen across a movement joint.
- Assembly and performance rooms
Community halls, church buildings and resort function rooms are hard volumes carrying amplified speech.
04 / Room by room
Room by room, on a typical Port Blair job
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date.
- 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 panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- 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. A replacement means waiting for the next sailing. We confirm the specification and send samples before anything ships.
- 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
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Plant and projection
Equipment noise into the auditorium, treated at source. PET felt does not absorb moisture, rot or corrode, which matters where almost everything else degrades quickly.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic panels, ASTM C423
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
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
Why the climate in Port Blair changes the material, not the target
Port Blair 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.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
06 / Straight talk
The six errors that cost the most
-
A shared service void running across the wall line
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating the auditorium to fix bleed from the next screen
It sounds like a small detail until the room is finished and the complaint arrives.
-
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 Port Blair job
Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date.
05 / Getting it there
Supply into Port Blair, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | a ship leg after Chennai |
| Dispatch | 2 to 4 working days |
| To site | a ship leg after Chennai |
| 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 to Chennai or Kolkata, then by ship to the islands. The sailing is scheduled and we plan the whole journey around it.
Questions from Port Blair projects
What makes cinema and multiplex soundproofing different in Port Blair?
Community halls, church buildings and resort function rooms are hard volumes carrying amplified speech. Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date.
Where should the budget go first on a Port Blair 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 Port Blair?
No. We manufacture in India and supply into Port Blair. 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 Port Blair site?
made at: Our own plant, Palwal, Haryana, reaches site in: a ship leg after Chennai, 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
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
