Manufactured in India, supplied in Bulgaria
Soundproofing materials in Bulgaria
We manufacture soundproofing materials 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.

- One batch across the order, no blending between runs
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 material, and what it actually does on a Bulgaria job
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
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.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials 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
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.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

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 decides the build-up in Bulgaria
- 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.
- Plant and HVAC
District heating and split units, with condensers on facades and in courtyards.
- The housing stock
Panel block housing and newer concrete construction, both with hard floors and slabs that pass impact noise.
Architects working in Bulgaria 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 Bulgaria, before acoustics is discussed
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.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
05 / Getting it there
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, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.
06 / Read this first
Where this goes wrong, said plainly
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
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.
-
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.

The material in real interiors
Bulgaria: questions we are actually asked
Where are the soundproofing materials 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 changes the specification on a Bulgaria job?
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.
How does the Bulgaria climate affect this product?
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.
How quickly can material reach a site in Bulgaria?
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.
What should you not buy soundproofing materials for?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
What quantity do we have to order, and in what packaging?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.
Next step
Drawings in, BOQ and a delivered date out
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.
