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 Brazil
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 Brazil is mostly offices and corporate towers, apartments, hotels, schools, hospitals, studios.
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 Brazil.
02 / Specification sheet
The published figures, unchanged by location
Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.
- 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

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.
03 / On the ground
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.
- Assembly and performance rooms
Churches, event halls and auditoriums are large hard rooms carrying amplified music at high level.
For a Brazil practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
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 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.
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.
05 / Route to site
Getting it to Brazil, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Santos or Paranaguá, then road to site |
| 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 or Paranaguá, then road to site. 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.
06 / Worth knowing
What we will tell you that a reseller will not
-
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.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.
-
Local approvals that nobody actually holds
We hold no Brazil certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Brazil: questions we are actually asked
Is there a Brazil 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 Brazil as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Santos or Paranaguá. You buy at factory prices with one consistent batch across the order.
What changes the specification on a 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. Hard flooring over concrete passes footfall straight down between apartments. A resilient underlay before the finish is the fix. Those two things move the build-up far more than the panel figure does.
Is this the right material for Brazil conditions?
Brazil 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 Brazil?
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 should you not buy wooden slat acoustic panels for?
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 is the minimum order and how is it packed?
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.
