Office acoustics and soundproofing in Brazil
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. Split units and VRF, with condensers in light wells and on facades close to bedrooms.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

What this material is and where it earns its place in Brazil
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
Split units and VRF, with condensers in light wells and on facades close to bedrooms.
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.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in Brazil.

02 / The build-up
The stack, in the order it is installed
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Brazil, split units and VRF, with condensers in light wells and on facades close to bedrooms.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
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.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Brazil, classrooms are concrete and tile with high ceilings and hard floors, and covered play areas amplify everything.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
If you are specifying for a Brazil project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What we see driving Brazil briefs
- 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.
- Plant and HVAC
Split units and VRF, with condensers in light wells and on facades close to bedrooms.
04 / Room by room
What each space in a Brazil project needs
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. The structure blocks well. The rooms are tile, glass and plaster with nothing to absorb anything, so speech carries and lecture rooms fail.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. Hard flooring over concrete passes footfall straight down between apartments. A resilient underlay before the finish is the fix.
- Ceiling baffles and clouds, 9 to 24 mm
- PET felt acoustic panels, 4 to 24 mm
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. 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.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- SoundBlanket mass loaded vinyl, 5 x 1.2 m, 6 sq m per roll
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 / Durability
Why the climate in Brazil changes the material, not the target
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.
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.

Six mistakes that turn into a second fit-out
-
Lining every wall while leaving the ceiling bare
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 a privacy problem with absorption
Nobody has ever achieved speech privacy with a panel. Privacy needs mass, a sealed head detail and a door that actually closes.
-
Glass cabins specified without a door and head detail
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.

Questions from Brazil projects
What makes office acoustics and soundproofing different in Brazil?
Split units and VRF, with condensers in light wells and on facades close to bedrooms. 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?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
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?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
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.
