- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
- Test reports sent on request, not just quoted
Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.
01 / What it is
The product, described honestly, for a Sri Lanka brief
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.
Work reaching us from Sri Lanka is mostly hotels and resorts, apartments, offices, hospitals, schools, studios.
Concrete and block construction with hard floors, in houses and new apartment towers that share slabs.
- Corner loading Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
- First reflection points Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
- Behind a fabric frame Where the room has to look finished, absorber inside a frame rather than foam on show.
- What it will not do Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for acoustic foam and bass traps are on the main product page. This page covers what that means for a project in Sri Lanka.
02 / Specification
Published specification, identical wherever we ship it
Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.
- Foam wedge and pyramidLow density. Flutter and high frequency only
- BassBloc100 kg per cubic metre. Low mid absorption, control rooms, live rooms
| BassBloc size | 1800 x 900 mm |
|---|---|
| BassBloc thickness | 20 mm |
| BassBloc density | 100 kg per cubic metre |
| Effective range | 100 to 500 Hz |
| BassBloc NRC | 0.85 |
Where a consultant is already engaged on a Sri Lanka project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / Local conditions
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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
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 sensible material list before acoustics is even 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 risk we design against here is mould, sagging fabric finishes and swelling in timber.
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
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 |
| Packing | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 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.
Sea freight into Colombo, then a short road run to site. The short transit means even modest consignments move economically. Air freight for samples.
The same minimums apply on export.
| Acoustic foam | 200 sq ft, about 19 sq m |
|---|---|
| BassBloc | 300 sq ft, about 28 sq m |
| Bass traps | 10 pieces |
A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels.
06 / Worth knowing
Four honest warnings before you buy
-
The wrong product for the problem
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.
-
Local approvals that nobody actually holds
We hold no Sri Lanka certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

The material in real interiors
Sri Lanka: questions we are actually asked
Is there a Sri Lanka factory behind this product?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Sri Lanka as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Colombo. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Sri Lanka project?
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. Resorts and city hotels drive most enquiries. Guest room isolation and function room acoustics are the two recurring briefs. Those two things move the build-up far more than the panel figure does.
Is this the right material for Sri Lanka conditions?
Sri Lanka is warm and humid through most of the year, with a long wet season. 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.
How does an order actually travel to Sri Lanka?
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.
When are acoustic foam and BassBloc the wrong purchase?
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
What is the minimum order and how is it packed?
The same minimums apply on export. Acoustic foam, 200 sq ft, about 19 sq m. BassBloc, 300 sq ft, about 28 sq m. Bass traps, 10 pieces. A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels. Compressed and boxed for foam, palletised flat for BassBloc.
