Cinema and multiplex soundproofing in Sao Paulo
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.
- Plant and projection
- Equipment noise into the auditorium, treated at source.

01 / The product
What this material is and where it earns its place in Sao Paulo
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 Sao Paulo is mostly corporate towers, apartments, restaurants, hotels, clinics, studios, schools.
- Towers block, interiors ring Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
- Traffic and helicopters Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes.
- Impact between apartments Hard floors over slabs pass footfall down. The underlay has to go in before the finish, not after the complaint.
- 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 Sao Paulo.
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 Sao Paulo, split units and VRF, with condensers in light wells and on facades close to bedrooms.
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
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 Sao Paulo, churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Sao Paulo, classrooms are concrete and tile with high ceilings and hard floors, and covered play areas amplify everything.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
Architects working in Sao Paulo 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 the buildings in Sao Paulo do to the specification
- Towers block, interiors ring
Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
- Traffic and helicopters
Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes.
- Impact between apartments
Hard floors over slabs pass footfall down. The underlay has to go in before the finish, not after the complaint.
- Santos, then the climb inland
The port leg and the road leg are separate costs and separate time. We quote both rather than one.
- Assembly and performance rooms
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
04 / Room by room
Room by room, on a typical Sao Paulo job
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
- 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
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Acoustic carpet and rugs, High density polyester
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Acoustic carpet and rugs, Felt
-
Plant and projection
Equipment noise into the auditorium, treated at source. Hard floors over slabs pass footfall down. The underlay has to go in before the finish, not after the complaint.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic panels, ASTM C423
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Durability
Why the climate in Sao Paulo changes the material, not the target
Sao Paulo 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.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
06 / Straight talk
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
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 Sao Paulo job
Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
05 / Logistics
What the route into Sao Paulo actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Santos, then road up to Sao Paulo |
| 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, then road up to Sao Paulo. Air freight for samples and urgent quantities.
Questions from Sao Paulo projects
What makes cinema and multiplex soundproofing different in Sao Paulo?
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level. Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
Where should the budget go first on a Sao Paulo 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 Sao Paulo?
No. We manufacture in India and supply into Sao Paulo. 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 Sao Paulo site?
ships from: Palwal, Haryana, India, arrives at: Santos, then road up to Sao Paulo, 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.
Next step
Tell us the room, we will tell you the build-up
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
