Cinema and multiplex soundproofing in Brazil
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. Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
- 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.

01 / The material
What you are buying, and what it fixes in Brazil
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.
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
Work reaching us from Brazil is mostly offices and corporate towers, apartments, hotels, schools, hospitals, studios.
- Concrete and block, hard inside The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
- Impact through slabs Hard flooring over concrete passes footfall straight down between apartments. A resilient underlay before the finish is the fix.
- A long sea leg and a real import process Transit is long and customs takes time. We quote the full window and give you the documentation package up front rather than after the container sails.
- 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 Brazil.
02 / The build-up
What goes where, from the structure in
-
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 Brazil, split units and VRF, with condensers in light wells and on facades close to bedrooms.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
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 Brazil, churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Brazil, classrooms are concrete and tile with high ceilings and hard floors, and covered play areas amplify everything.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
Architects working in Brazil 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 / On the ground
What decides the build-up in Brazil
- Concrete and block, hard inside
The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
- Impact through slabs
Hard flooring over concrete passes footfall straight down between apartments. A resilient underlay before the finish is the fix.
- A long sea leg and a real import process
Transit is long and customs takes time. We quote the full window and give you the documentation package up front rather than after the container sails.
- Humid in most of the country
PET felt does not absorb moisture, shed fibre or feed mould, which matters where mineral products sag within a few seasons.
- Assembly and performance rooms
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
04 / Room by room
What each space in a Brazil project needs
-
Screen to screen
Independent construction between auditoria, with services broken at the line. The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic carpet and rugs, 4 mm
- PET felt acoustic panels, 4 to 24 mm
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Hard flooring over concrete passes footfall straight down between apartments. A resilient underlay before the finish is the fix.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic carpet and rugs, High density polyester
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Plant and projection
Equipment noise into the auditorium, treated at source. Transit is long and customs takes time. We quote the full window and give you the documentation package up front rather than after the container sails.
- 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
For a Brazil interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate and durability
The Brazil climate decides the material list
Brazil is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
Where a consultant is already engaged on a Brazil project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Before you buy
What we watch go wrong on jobs like this
-
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
This is the one that comes back as a second fit-out rather than a snag.
-
Doors and lobbies specified late and undersized
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
Treating it as a generic Brazil job
The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
05 / Logistics
What the route into Brazil actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Santos or Paranaguá, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Santos |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into Santos or Paranaguá, then road to site. Air freight for samples and urgent quantities.
Questions from Brazil projects
What makes cinema and multiplex soundproofing different in Brazil?
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level. The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
Where should the budget go first on a Brazil 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 Brazil?
No. We manufacture in India and supply into Brazil. 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 Brazil site?
ships from: Palwal, Haryana, India, arrives at: Santos or Paranaguá, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
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.

Drawings in, BOQ and a delivered date out
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
