Home theatre soundproofing and acoustics in Prague
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is. Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
- Containment
- Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
- Low frequency inside
- Corner absorption with depth, before any surface treatment.
- Reflections
- Side wall and ceiling first reflection points at the seating position.

01 / What it is
The material, and what it actually does on a Prague job
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is.
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
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.
- Containment Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for home theatre soundproofing are on the main product page. This page covers what that means for a project in Prague.
02 / The build-up
How the layers stack, from the structure inwards
-
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.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
Layer 2
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Prague, concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster.
Full height with return. Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Prague, school buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
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 / Local conditions
What decides the build-up in Prague
- 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.
- The housing stock
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
04 / Room by room
What each space in a Prague project needs
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. 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.
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
- Soundproof curtains, 10 to 12 mm
- Acoustic carpet and rugs, High density polyester
-
Low frequency inside
Corner absorption with depth, before any surface treatment. 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.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Soundproof curtains, 5.5 kg per sq m
- Acoustic carpet and rugs, Felt
-
Reflections
Side wall and ceiling first reflection points at the seating position. 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.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Soundproof curtains, Up to 30 dB
- Acoustic carpet and rugs, 64 sq ft per pack
For a Prague interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate
Durability in Prague, before acoustics is discussed
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.
On a Prague job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

Where this kind of project usually fails
-
Foam on the walls as a soundproofing measure
It sounds like a small detail until the room is finished and the complaint arrives.
-
A standard door on a room built to hold bass
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating before the room is sealed
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 home theatre soundproofing and acoustics different in Prague?
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall. 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?
Containment. Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Low frequency inside. Corner absorption with depth, before any surface treatment.
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?
Foam on the walls as a soundproofing measure. A standard door on a room built to hold bass.
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.
