Manufactured in India, supplied in Bulgaria
SoundBlanket mass loaded vinyl in Bulgaria
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Bulgaria. Made at our own plant in India and shipped into Varna or Burgas on the Black Sea, then road inland.

01 / Start here
What this is, and what it changes in a Bulgaria 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 Bulgaria is mostly coastal and ski resorts, offices and service centres, panel block housing, schools, hospitals.
Panel block housing and newer concrete construction, both with hard floors and slabs that pass impact noise.
- 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 Bulgaria.
02 / Specification
The published figures, unchanged by location
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.
- 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

Where a consultant is already engaged on a Bulgaria 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 the buildings in Bulgaria do to the specification
- Two seasons, two deadlines
Coastal work finishes before summer and mountain work before winter. Real dates matter more than a marginally better price.
- Panel block housing
Prefabricated concrete blocks pass speech and footfall between flats through thin, well connected elements. Surface treatment does nothing.
- Service centre floors
Large rooms full of people on calls, where speech privacy rather than echo is the actual problem.
- Black Sea ports, then road
Varna and Burgas both serve the country well. We quote the sea leg and the inland leg separately.
- The housing stock
Panel block housing and newer concrete construction, both with hard floors and slabs that pass impact noise.
- The studio and content scene
A small but growing production sector working inside existing buildings with good mass.
If you are specifying for a Bulgaria project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Durability
Why the climate in Bulgaria changes the material, not the target
Bulgaria is cold winters and warm summers, with a wide annual temperature range, and that narrows the sensible material list before acoustics is even discussed.
A wide annual swing stresses adhesive fixings and moves timber. Mechanical fixing beats adhesive alone, and PET felt is stable across the range.
The risk we design against here is adhesive failure and timber movement across the annual swing.
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 / Logistics
What the route into Bulgaria actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Varna or Burgas, then road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Varna or Burgas |
| 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 Varna or Burgas, then road inland. 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 / Before you buy
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.
-
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.
-
Suppliers who imply a Bulgaria 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.
Bulgaria: questions we are actually asked
Where are the soundBlanket mass loaded vinyl you supply to Bulgaria actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Bulgaria as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Varna or Burgas on the Black Sea, then road inland. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Bulgaria project?
Coastal work finishes before summer and mountain work before winter. Real dates matter more than a marginally better price. Prefabricated concrete blocks pass speech and footfall between flats through thin, well connected elements. Surface treatment does nothing. Those two things move the build-up far more than the panel figure does.
Does Bulgaria weather shorten the life of this material?
Bulgaria is cold winters and warm summers, with a wide annual temperature range. A wide annual swing stresses adhesive fixings and moves timber. Mechanical fixing beats adhesive alone, and PET felt is stable across the range. The failure we design against here is adhesive failure and timber movement across the annual swing.
When would material land on a Bulgaria site?
ships from: Palwal, Haryana, India, arrives at: Varna or Burgas, then road inland, 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 soundBlanket mass loaded vinyl the wrong purchase?
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 quantity do we have to order, and in what packaging?
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.

A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
