Office acoustics and soundproofing in Sri Lanka
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. Split units and generator sets, with condensers close to bedrooms and generators running during outages.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

01 / What it is
The material, and what it actually does on a Sri Lanka job
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
Split units and generator sets, with condensers close to bedrooms and generators running during outages.
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.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in Sri Lanka.

02 / The build-up
The stack, in the order it is installed
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Sri Lanka, split units and generator sets, with condensers close to bedrooms and generators running during outages.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
Layer 2
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Sri Lanka, temples, churches and function halls are hard volumes with long decay 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
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Sri Lanka, classrooms are hard and naturally ventilated with large class sizes and open corridors.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
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 / What drives the brief
The Sri Lanka conditions that change the answer
- 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.
- Plant and HVAC
Split units and generator sets, with condensers close to bedrooms and generators running during outages.

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 / Climate
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.
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
Six mistakes that turn into a second fit-out
-
Lining every wall while leaving the ceiling bare
Square metre for square metre the ceiling is the cheapest result in the room. Skipping it and buying wall panels instead is the most common way to overspend.
-
Treating a privacy problem with absorption
Nobody has ever achieved speech privacy with a panel. Privacy needs mass, a sealed head detail and a door that actually closes.
-
Glass cabins specified without a door and head detail
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 / Route to site
How material reaches 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 |
| 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 office acoustics and soundproofing different in Sri Lanka?
Split units and generator sets, with condensers close to bedrooms and generators running during outages. 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?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
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?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
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.

Send the drawings, get a straight answer
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.
