Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.
01 / The material
What you are buying, and what it fixes in Sao Paulo
Wood fibre bound into a rigid board with an open texture. Robust, paintable and used where the surface takes knocks, which is why it ends up in schools, sports halls and plant rooms.
Work reaching us from Sao Paulo is mostly corporate towers, apartments, restaurants, hotels, clinics, studios, schools.
Concrete frame with block infill and hard floors. Apartment towers share slabs and walls, and impact noise between floors is the common complaint.
- Direct fix Mechanically fixed to the soffit or wall. Durable and simple.
- On a cavity Mounted on battens with an air gap, which is where the low mid performance comes from.
- With a porous backing Board over mineral backing where the room needs more than the board alone gives.
- What it will not do At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wood wool panels are on the main product page. This page covers what that means for a project in Sao Paulo.
02 / Specification
The published figures, unchanged by location
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings
| Panel size | 1200 x 600 mm |
|---|---|

| Test standards | ASTM C-423 and EN ISO 354 |
| Surface burning | Class A to ASTM E84 |
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.
03 / What drives the brief
The Sao Paulo conditions that change the answer
- 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.
- School and campus buildings
Classrooms are concrete and tile with high ceilings and hard floors, and covered play areas amplify everything.
For a Sao Paulo practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Durability
What the Sao Paulo climate rules in and rules out
Sao Paulo is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even 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 risk we design against here is mould, sagging fabric finishes and swelling in timber.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Supply
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 |
| Packing | Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected. |
| Lead time | 4 to 7 working days for standard sizes. |
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.
The same 500 sq ft minimum applies on export.
| Any finish | 500 sq ft, about 46 sq m |
|---|
A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels.
06 / Read this first
Where this goes wrong, said plainly
-
The wrong product for the problem
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.
-
Local approvals that nobody actually holds
We hold no Sao Paulo certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Sao Paulo: questions we are actually asked
Are these wood wool acoustic panels made in Sao Paulo?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Sao Paulo as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Santos, then road up to the city, with both legs quoted separately. You buy at factory prices with one consistent batch across the order.
Why would a Sao Paulo build-up differ from anywhere else?
Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live. Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes. Those two things move the build-up far more than the panel figure does.
Is this the right material for Sao Paulo conditions?
Sao Paulo is warm and humid through most of the year, with a long wet season. 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.
When would material land on 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 will wood wool acoustic panels not do?
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
How is the order packed and what is the minimum?
The same 500 sq ft minimum applies on export. Any finish, 500 sq ft, about 46 sq m. A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels. Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected.

Drawings in, BOQ and a delivered date out
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.
