Manufactured in India, supplied in Sweden
SoundBlanket mass loaded vinyl in Sweden
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Sweden. Made at our own plant in India and shipped into Gothenburg, then road onward, with the domestic leg quoted separately because Sweden is a long country.

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 is, and what it changes in a Sweden room
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 Sweden is mostly timber buildings and apartments, offices, schools, healthcare, hotels, studios.
Concrete apartment blocks and timber frame housing with tight envelopes, hard floors and cold external walls.
- 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 Sweden.
02 / Data sheet
The numbers, and they do not move by city
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- 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 |
|---|---|

| 4 mm | STC 34, 8.4 kg per sq m |
| 6 mm | 12.6 kg per sq m, STC on request |
| Roll size | 5 x 1.2 m, 6 sq m per roll |
| Form | Limp sheet, cuts with a knife, seams lapped and sealed |
Where a consultant is already engaged on a Sweden 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 Sweden
- Timber at scale
Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work.
- Classes are written and verified
Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it.
- Sealed through a long winter
Ventilation runs constantly in closed buildings, so plant noise matters more than street noise.
- A long country
A site in the north has a real domestic leg. We quote it separately so the dates are honest.
- The housing stock
Concrete apartment blocks and timber frame housing with tight envelopes, hard floors and cold external walls.
- The studio and content scene
A very deep music production culture where absorption data and measured targets are expected.
Architects working in Sweden 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 / Climate and durability
Durability in Sweden, before acoustics is discussed
Sweden is cool and damp, with long heating seasons and cold external walls, and that narrows the sensible material list before acoustics is even discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The risk we design against here is condensation behind linings in older, poorly insulated stock.
For a Sweden interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Getting it there
How material reaches a Sweden site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Gothenburg, then road onward to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Gothenburg |
| 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. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into Gothenburg, then road onward to site. Air freight for samples and urgent quantities.
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 / Straight talk
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.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.
-
A claim of being local to Sweden
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.
Sweden: questions we are actually asked
Where are the soundBlanket mass loaded vinyl you supply to Sweden actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Sweden as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Gothenburg, then road onward, with the domestic leg quoted separately because Sweden is a long country. You buy at factory prices with one consistent batch across the order.
Why would a Sweden build-up differ from anywhere else?
Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it. Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work. Those two things move the build-up far more than the panel figure does.
Is this the right material for Sweden conditions?
Sweden is cool and damp, with long heating seasons and cold external walls. Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would. The failure we design against here is condensation behind linings in older, poorly insulated stock.
How does an order actually travel to Sweden?
ships from: Palwal, Haryana, India, arrives at: Gothenburg, then road onward to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Where do soundBlanket mass loaded vinyl fail to help?
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.
What is the minimum order and how is it packed?
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.
