Cinema and multiplex soundproofing in Sri Lanka
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. Temples, churches and function halls are hard volumes with long decay 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 product
What this is, and what it changes in a Sri Lanka 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.
Temples, churches and function halls are hard volumes with long decay carrying amplified speech.
Work reaching us from Sri Lanka is mostly hotels and resorts, apartments, offices, hospitals, schools, studios.
- A very short sea leg Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets.
- Hospitality leads the market Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs.
- Humid, coastal, monsoon Our PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- 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 Sri Lanka.
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 Sri Lanka, split units and generator sets, with condensers close to bedrooms and generators running during outages.
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
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 Sri Lanka, temples, churches and function halls are hard volumes with long decay carrying amplified speech.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Sri Lanka, classrooms are hard and naturally ventilated with large class sizes and open corridors.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
Architects working in Sri Lanka 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 / Local conditions
What the buildings in Sri Lanka do to the specification
- A very short sea leg
Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets.
- Hospitality leads the market
Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs.
- Humid, coastal, monsoon
Our PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- Buying direct from the plant
No importer margin between the factory and your site, and the person answering the technical question made the product.
- Assembly and performance rooms
Temples, churches and function halls are hard volumes with long decay carrying amplified speech.
04 / Room by room
Space by space, for Sri Lanka briefs
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets.
- 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. Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs.
- 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. Our PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- 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 and durability
Why the climate in Sri Lanka changes the material, not the target
Sri Lanka 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.

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
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 Sri Lanka job
Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets.
05 / Getting it there
Supply into Sri Lanka, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Colombo, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Colombo |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Colombo, then a short road run to site. The short transit means even modest consignments move economically. Air freight for samples.
Questions from Sri Lanka projects
What makes cinema and multiplex soundproofing different in Sri Lanka?
Temples, churches and function halls are hard volumes with long decay carrying amplified speech. Western India to Colombo is one of the quickest runs we operate. Small and repeat orders are practical here in a way they are not for distant markets.
Where should the budget go first on a Sri Lanka 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 Sri Lanka?
No. We manufacture in India and supply into Sri Lanka. 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 Sri Lanka site?
ships from: Palwal, Haryana, India, arrives at: Colombo, then a short road run to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. 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.
