Hospital and healthcare acoustics in Sao Paulo
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed. Split units and VRF, with condensers in light wells and on facades close to bedrooms.
- Consulting room privacy
- Speech privacy between rooms, which is partition, door and ceiling void work.
- Ward noise floor
- Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
- Cleanability
- Non shedding, non absorbent surfaces that survive a cleaning regime.

01 / What it is
The material, and what it actually does on a Sao Paulo job
Two duties at once: privacy where confidential conversations happen, and a lower noise floor where people are trying to rest. Hygiene and cleanability rule out a lot of products before acoustics is even discussed.
Split units and VRF, with condensers in light wells and on facades close to bedrooms.
Work reaching us from Sao Paulo is mostly corporate towers, apartments, restaurants, hotels, clinics, studios, schools.
- Santos, then the climb inland The port leg and the road leg are separate costs and separate time. We quote both rather than one.
- 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.
- Consulting room privacy Speech privacy between rooms, which is partition, door and ceiling void work.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for healthcare acoustics are on the main product page. This page covers what that means for a project in Sao Paulo.
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 Sao Paulo, split units and VRF, with condensers in light wells and on facades close to bedrooms.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Sao Paulo, churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
Loose lay on tackifier. Tiles lifted individually for access under a raised floor, which is why tile beats broadloom in an office.
-
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 Sao Paulo, classrooms are concrete and tile with high ceilings and hard floors, and covered play areas amplify everything.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
If you are specifying for a Sao Paulo 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 the buildings in Sao Paulo do to the specification
- Santos, then the climb inland
The port leg and the road leg are separate costs and separate time. We quote both rather than one.
- 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.
- Plant and HVAC
Split units and VRF, with condensers in light wells and on facades close to bedrooms.
04 / Room by room
Where the money goes on a Sao Paulo project
-
Consulting room privacy
Speech privacy between rooms, which is partition, door and ceiling void work. The port leg and the road leg are separate costs and separate time. We quote both rather than one.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Ward noise floor
Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling. Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic panels, ASTM C423
-
Cleanability
Non shedding, non absorbent surfaces that survive a cleaning regime. Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes.
- PET felt acoustic panels, 4 to 24 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
For a Sao Paulo 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
Durability in Sao Paulo, before acoustics is discussed
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.
Where a consultant is already engaged on a Sao Paulo project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

The six errors that cost the most
-
Fabric wrapped products in a clinical area
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Absorption used where privacy was the requirement
Privacy is a transmission problem. Absorption makes the room sound nicer and does not stop anyone hearing through the wall.
-
Ceiling void left open above a partition
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating it as a generic Sao Paulo job
The port leg and the road leg are separate costs and separate time. We quote both rather than one.
05 / Route to site
Getting it to Sao Paulo, with real dates
| 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 hospital and healthcare acoustics different in Sao Paulo?
Split units and VRF, with condensers in light wells and on facades close to bedrooms. 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?
Consulting room privacy. Speech privacy between rooms, which is partition, door and ceiling void work. Ward noise floor. Alarms, trolleys and staff conversation in hard corridors. Absorption at the ceiling.
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?
Fabric wrapped products in a clinical area. Absorption used where privacy was the requirement.
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 a plan and a section, get a real build-up
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.
