Office acoustics and soundproofing in Bulgaria
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. District heating and split units, with condensers on facades and in courtyards.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

01 / What it is
The material, and what it actually does on a Bulgaria job
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
District heating and split units, with condensers on facades and in courtyards.
Work reaching us from Bulgaria is mostly coastal and ski resorts, offices and service centres, panel block housing, schools, hospitals.
- 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.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in Bulgaria.

02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Bulgaria, district heating and split units, with condensers on facades and in courtyards.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bulgaria, church buildings and civic halls are stone volumes with long decay times.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 3
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Bulgaria, school buildings are hard surfaced with long corridors and gymnasiums serving as halls.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
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.

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.
04 / Room by room
What each space in a Bulgaria project needs
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Coastal work finishes before summer and mountain work before winter. Real dates matter more than a marginally better price.
- Acoustic carpet and rugs, 500 x 500 mm
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. Prefabricated concrete blocks pass speech and footfall between flats through thin, well connected elements. Surface treatment does nothing.
- Acoustic carpet and rugs, 4 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. Large rooms full of people on calls, where speech privacy rather than echo is the actual problem.
- Acoustic carpet and rugs, High density polyester
- Acoustic panels, ASTM C423
- SoundBlanket mass loaded vinyl, 5 x 1.2 m, 6 sq m per roll
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.
04 / Conditions
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 material list before acoustics is 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 failure we design against here is adhesive failure and timber movement across the annual swing.
On a Bulgaria job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Straight talk
Where this kind of project usually fails
-
Lining every wall while leaving the ceiling bare
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating a privacy problem with absorption
Nobody has ever achieved speech privacy with a panel. Privacy needs mass, a sealed head detail and a door that actually closes.
-
Glass cabins specified without a door and head detail
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.
-
Treating it as a generic Bulgaria job
Coastal work finishes before summer and mountain work before winter. Real dates matter more than a marginally better price.
05 / Logistics
How material reaches a Bulgaria 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 |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
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.
Questions from Bulgaria projects
What makes office acoustics and soundproofing different in Bulgaria?
District heating and split units, with condensers on facades and in courtyards. Coastal work finishes before summer and mountain work before winter. Real dates matter more than a marginally better price.
Where should the budget go first on a Bulgaria project?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
Do you have an office or installation team in Bulgaria?
No. We manufacture in India and supply into Bulgaria. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to 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.
What goes wrong most often on this kind of project?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
