Cinema and multiplex soundproofing in Bulgaria
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes. Church buildings and civic halls are stone volumes with long decay times.
- Screen to screen
- Independent construction between auditoria, with services broken at the line.
- In room response
- Heavy absorption on side and rear walls so the mix is heard as intended.
- Plant and projection
- Equipment noise into the auditorium, treated at source.

What this material is and where it earns its place in Bulgaria
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes.
Church buildings and civic halls are stone volumes with long decay times.
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.
- Screen to screen Independent construction between auditoria, with services broken at the line.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for cinema soundproofing are on the main product page. This page covers what that means for a project in Bulgaria.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Bulgaria, district heating and split units, with condensers on facades and in courtyards.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 2
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, church buildings and civic halls are stone volumes with long decay times.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bulgaria, school buildings are hard surfaced with long corridors and gymnasiums serving as halls.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
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.
- Assembly and performance rooms
Church buildings and civic halls are stone volumes with long decay times.

In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Prefabricated concrete blocks pass speech and footfall between flats through thin, well connected elements. Surface treatment does nothing.

- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft

Plant and projection
Equipment noise into the auditorium, treated at source. Large rooms full of people on calls, where speech privacy rather than echo is the actual problem.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate
Durability in Bulgaria, before acoustics is discussed
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 / Worth knowing
What we watch go wrong on jobs like this
-
A shared service void running across the wall line
Square metre for square metre the ceiling is the cheapest result in the room. Skipping it and buying wall panels instead is the most common way to overspend.
-
Treating the auditorium to fix bleed from the next screen
Small on the drawing, expensive on site, and almost always found after handover.
-
Doors and lobbies specified late and undersized
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
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 cinema and multiplex soundproofing different in Bulgaria?
Church buildings and civic halls are stone volumes with long decay times. 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?
Screen to screen. Independent construction between auditoria, with services broken at the line. In room response. Heavy absorption on side and rear walls so the mix is heard as intended.
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?
A shared service void running across the wall line. Treating the auditorium to fix bleed from the next screen.
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.
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.
