Home theatre soundproofing and acoustics in Sri Lanka
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is. Concrete and block construction with hard floors, in houses and new apartment towers that share slabs.
- Containment
- Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
- Low frequency inside
- Corner absorption with depth, before any surface treatment.
- Reflections
- Side wall and ceiling first reflection points at the seating position.

01 / The material
What this is, and what it changes in a Sri Lanka room
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is.
Concrete and block construction with hard floors, in houses and new apartment towers that share slabs.
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.
- Containment Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for home theatre soundproofing are on the main product page. This page covers what that means for a project in Sri Lanka.
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 Sri Lanka, split units and generator sets, with condensers close to bedrooms and generators running during outages.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 2
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Sri Lanka, temples, churches and function halls are hard volumes with long decay carrying amplified speech.
Track with a seal. Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
-
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.
If you are specifying for a Sri Lanka project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
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.
- The housing stock
Concrete and block construction with hard floors, in houses and new apartment towers that share slabs.

Space by space, for Sri Lanka briefs
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. 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.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Soundproof curtains, 10 to 12 mm
- Acoustic carpet and rugs, High density polyester
-
Low frequency inside
Corner absorption with depth, before any surface treatment. Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproof curtains, 5.5 kg per sq m
- Acoustic carpet and rugs, Felt
-
Reflections
Side wall and ceiling first reflection points at the seating position. Our PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproof curtains, Up to 30 dB
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
Durability in Sri Lanka, before acoustics is discussed
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.
On a Sri Lanka job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
What we watch go wrong on jobs like this
-
Foam on the walls as a soundproofing measure
This is the one that comes back as a second fit-out rather than a snag.
-
A standard door on a room built to hold bass
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating before the room is sealed
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.

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 / Route to site
Getting it to Sri Lanka, with real dates
| 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 home theatre soundproofing and acoustics different in Sri Lanka?
Concrete and block construction with hard floors, in houses and new apartment towers that share slabs. 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?
Containment. Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Low frequency inside. Corner absorption with depth, before any surface treatment.
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?
Foam on the walls as a soundproofing measure. A standard door on a room built to hold bass.
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
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.
