Manufactured in India, supplied in Bulgaria
Wooden slat acoustic panels in Bulgaria
We manufacture wooden slat 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
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 / The material
What this is, and what it changes in a Bulgaria room
Timber slats on an acoustic backing. The slats are the finish and the rhythm, the backing does the absorbing. Used where the room has to look considered rather than treated.
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.
- Slats on felt backing The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
- Slats on a cavity Backing plus an air gap behind moves absorption lower, which matters in music rooms.
- Feature wall only Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
- What it will not do A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wooden slat panels are on the main product page. This page covers what that means for a project in Bulgaria.
02 / Specification sheet
Published specification, identical wherever we ship it
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.
- MDFStandard. Dry interiors, general commercial
- FR MDFFire rated. Public buildings and anywhere the specification calls for a class
- HDHMRMoisture resistant. Humid climates and rooms that see damp

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 / In this market
What we see driving Bulgaria briefs
- 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.
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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Logistics
Supply into Bulgaria, start to site
| 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 | Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry. |
| Lead time | Longer than felt. Confirmed against the pattern and substrate at quote stage. |
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 specification | 500 sq ft, about 46 sq m |
|---|
One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order.
06 / Straight talk
Four honest warnings before you buy
-
The wrong product for the problem
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
-
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 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
Are these wooden slat acoustic panels made 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 do you look at first on a Bulgaria enquiry?
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.
When are wooden slat acoustic panels the wrong purchase?
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
How is the order packed and what is the minimum?
The same 500 sq ft minimum applies on export. Any specification, 500 sq ft, about 46 sq m. One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order. Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry.

Send a plan and a section, get a real build-up
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.
