We make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.
01 / The product
What this material is and where it earns its place in Sri Lanka
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. It is the barrier product, not an absorber, and it is the right answer when the problem is noise passing through a structure.
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.
- Wall, decoupled Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
- Floor, floating Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
- Duct and plant wrap Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
- What it will not do Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for SoundBlanket MLV are on the main product page. This page covers what that means for a project in Sri Lanka.
02 / Specification sheet
Published specification, identical wherever we ship it
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- 2.5 mmSTC 30, 5.25 kg per sq m. Ducts, light partitions, retrofit where depth is tight
- 4 mmSTC 34, 8.4 kg per sq m. Party walls, floors, plant rooms, the common specification
- 6 mm12.6 kg per sq m. Machine enclosures and low frequency problems
| Density | 2100 kg per cubic metre |
|---|---|

| Roll size | 5 x 1.2 m, 6 sq m per roll |
| Form | Limp sheet, cuts with a knife, seams lapped and sealed |
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.
03 / Local conditions
What the buildings in Sri Lanka do to the specification
- 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.
- 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.
- 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.
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.
04 / Durability
The Sri Lanka climate decides the material list
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.
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.
05 / Logistics
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 |
| Packing | Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters. |
| Lead time | 4 to 7 working days. Full container quantities scheduled against the vessel. |
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 as on domestic orders.
| 2.5 mm and 4 mm | 10 rolls, 60 sq m |
|---|---|
| 6 mm and other thicknesses | 10 tonnes per thickness |
A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm.
06 / Worth knowing
Four honest warnings before you buy
-
The wrong product for the problem
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.
-
Suppliers who imply a Sri Lanka presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Sri Lanka: questions we are actually asked
Are these soundBlanket mass loaded vinyl made in Sri Lanka?
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 do you look at first on a Sri Lanka enquiry?
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.
How does the Sri Lanka climate affect this product?
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.
What will soundBlanket mass loaded vinyl not do?
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
Is there a minimum order, and how does it arrive?
The same minimums apply on export as on domestic orders. 2.5 mm and 4 mm, 10 rolls, 60 sq m. 6 mm and other thicknesses, 10 tonnes per thickness. A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm. Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters.
