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 / What it is
The material, and what it actually does on a Sao Paulo job
Timber slats on an acoustic backing. The slats are the finish and the rhythm, the backing does the absorbing. Used where the room has to look considered rather than treated.
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.
- Slats on felt backing The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
- Slats on a cavity Backing plus an air gap behind moves absorption lower, which matters in music rooms.
- Feature wall only Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
- What it will not do A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wooden slat panels are on the main product page. This page covers what that means for a project in Sao Paulo.
02 / Specification
Published specification, identical wherever we ship it
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- MDFStandard. Dry interiors, general commercial
- FR MDFFire rated. Public buildings and anywhere the specification calls for a class
- HDHMRMoisture resistant. Humid climates and rooms that see damp
| Substrate | MDF, FR MDF, HDF or HDHMR |
|---|---|
| Patterns | 13-3, 14-2, 28-4 and 59-5 |
| Panel sizes | 2440 x 192 mm and 2440 x 128 mm |
| Thickness | 14, 16 and 18 mm |
| Coverage | 96 sq ft per unit |
| Fire class | EN 13501-1 Class B s1 d0 on FR substrate |
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. 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.
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.
04 / Climate and 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 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 / Getting it there
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 |
| Packing | Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry. |
| Lead time | Longer than felt. Confirmed against the pattern and substrate at quote stage. |
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 specification | 500 sq ft, about 46 sq m |
|---|
One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order.

Four honest warnings before you buy
-
The wrong product for the problem
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.

Suppliers who imply a Sao Paulo presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Sao Paulo: questions we are actually asked
Is there a Sao Paulo factory behind this product?
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.
What do you look at first on a Sao Paulo enquiry?
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.
How does an order actually travel to Sao Paulo?
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.
Where do wooden slat acoustic panels fail to help?
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
What quantity do we have to order, and in what packaging?
The same 500 sq ft minimum applies on export. Any specification, 500 sq ft, about 46 sq m. One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order. Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry.
Next step
Tell us the room, we will tell you the 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.
