Recording studio acoustics and soundproofing in Sri Lanka
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later. A growing broadcast and music sector working inside converted commercial rooms.
- Isolation
- A measured background level, agreed before anything is bought.
- Low frequency
- Corner and boundary absorption with real depth, not surface foam.
- Early reflections
- Controlled at the mix position, and only there.

01 / The material
What this material is and where it earns its place in Sri Lanka
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later.
A growing broadcast and music sector working inside converted commercial rooms.
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.
- Isolation A measured background level, agreed before anything is bought.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for studio soundproofing are on the main product page. This page covers what that means for a project in Sri Lanka.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Acoustic foam and BassBloc
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing. In Sri Lanka, split units and generator sets, with condensers close to bedrooms and generators running during outages.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
-
Layer 2
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Sri Lanka, temples, churches and function halls are hard volumes with long decay carrying amplified speech.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
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 Sri Lanka, classrooms are hard and naturally ventilated with large class sizes and open corridors.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
For a Sri Lanka practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / In this market
What decides the build-up in Sri Lanka
- 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.
- The studio and content scene
A growing broadcast and music sector working inside converted commercial rooms.

Where the money goes on a Sri Lanka project
-
Isolation
A measured background level, agreed before anything is bought. 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.
- Acoustic foam and BassBloc, 1800 x 900 mm
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Soundproof curtains, 5.5 kg per sq m
-
Low frequency
Corner and boundary absorption with real depth, not surface foam. Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs.
- Acoustic foam and BassBloc, 20 mm
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Soundproof curtains, Up to 30 dB
-
Early reflections
Controlled at the mix position, and only there. Our PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a couple of seasons.
- Acoustic foam and BassBloc, 100 kg per cubic metre
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Soundproof curtains, 30
For a Sri Lanka interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Conditions
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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Before you buy
What we watch go wrong on jobs like this
-
Buying foam to solve an isolation problem
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating the room before the shell is isolated
Small on the drawing, expensive on site, and almost always found after handover.
-
Killing the room completely and calling it controlled
We would rather calculate the area and sell you less of it than line every surface and call it thorough.
-
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
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 recording studio acoustics and soundproofing different in Sri Lanka?
A growing broadcast and music sector working inside converted commercial rooms. 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?
Isolation. A measured background level, agreed before anything is bought. Low frequency. Corner and boundary absorption with real depth, not surface foam.
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?
Buying foam to solve an isolation problem. Treating the room before the shell is isolated.
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
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.
