Cinema and multiplex soundproofing in Prague
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. Concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster.
- 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.

01 / The material
What this material is and where it earns its place in Prague
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.
Concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster.
Work reaching us from Prague is mostly hotel conversions, apartments, production and studio spaces, offices, restaurants, clinics.
- Protected buildings, internal fixes only In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems.
- Conversions into guest rooms Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else.
- A production city Stages, edit rooms and post production spaces need the shell to isolate before anything else is decided. There is no partial credit on a room like that.
- 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 Prague.
02 / The build-up
What goes where, from the structure in
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Prague, mechanical ventilation in newer buildings and radiator heating in older stock, so duct noise is a newer problem than it looks.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
Layer 2
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 Prague, concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
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 Prague, school buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
Architects working in Prague usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / In this market
The Prague conditions that change the answer
- Protected buildings, internal fixes only
In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems.
- Conversions into guest rooms
Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else.
- A production city
Stages, edit rooms and post production spaces need the shell to isolate before anything else is decided. There is no partial credit on a room like that.
- Hard stone, long reverberation
Stone, plaster and tile in tall rooms hold sound for a long time. Speech stops being intelligible well before the room sounds obviously wrong.
- Assembly and performance rooms
Concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster.

In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else.

- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Plant and projection
Equipment noise into the auditorium, treated at source. Stages, edit rooms and post production spaces need the shell to isolate before anything else is decided. There is no partial credit on a room like that.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic carpet and rugs, Felt
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
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
What the Prague climate rules in and rules out
Prague is cool and damp, with long heating seasons and cold external walls, and that narrows the material list before acoustics is discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The failure we design against here is condensation behind linings in older, poorly insulated stock.
Where a consultant is already engaged on a Prague project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

Where this kind of project usually fails
-
A shared service void running across the wall line
A treated wall under a bare hard ceiling gives you a fraction of the reduction you paid for, and the room still sounds wrong.
-
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
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 Prague job
In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems.

Questions from Prague projects
What makes cinema and multiplex soundproofing different in Prague?
Concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster. In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems.
Where should the budget go first on a Prague 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 Prague?
No. We manufacture in India and supply into Prague. 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 Prague site?
ships from: Palwal, Haryana, India, arrives at: Hamburg, then rail and road into Prague, 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
Send the drawings, get a straight answer
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.
