Manufactured in India, supplied in Bulgaria
Wood wool acoustic panels in Bulgaria
We manufacture wood wool acoustic panels 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
We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / What it is
The material, and what it actually does on a Bulgaria job
Wood fibre bound into a rigid board with an open texture. Robust, paintable and used where the surface takes knocks, which is why it ends up in schools, sports halls and plant rooms.
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.
- Direct fix Mechanically fixed to the soffit or wall. Durable and simple.
- On a cavity Mounted on battens with an air gap, which is where the low mid performance comes from.
- With a porous backing Board over mineral backing where the room needs more than the board alone gives.
- What it will not do At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wood wool panels are on the main product page. This page covers what that means for a project in Bulgaria.
02 / Specification
One specification sheet, the same in every market
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.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings
| Panel size | 1200 x 600 mm |
|---|---|
| Thickness | 20 mm |
| Density | 400 kg per cubic metre |
| NRC | 0.30 |
| Test standards | ASTM C-423 and EN ISO 354 |
| Surface burning | Class A to ASTM E84 |
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.
- Assembly and performance rooms
Church buildings and civic halls are stone volumes with long decay times.
- School and campus buildings
School buildings are hard surfaced with long corridors and gymnasiums serving as halls.
For a Bulgaria practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
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.
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 / Supply
Getting it to Bulgaria, with real dates
| 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 | Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected. |
| Lead time | 4 to 7 working days for standard sizes. |
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 500 sq ft minimum applies on export.
| Any finish | 500 sq ft, about 46 sq m |
|---|
A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels.
06 / Worth knowing
Four honest warnings before you buy
-
The wrong product for the problem
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
-
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 Bulgaria certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Bulgaria: questions we are actually asked
Do you manufacture wood wool acoustic panels in Bulgaria?
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.
Is this the right material for Bulgaria conditions?
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.
Where do wood wool acoustic panels fail to help?
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
How is the order packed and what is the minimum?
The same 500 sq ft minimum applies on export. Any finish, 500 sq ft, about 46 sq m. A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels. Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected.
