This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / Start here
What this is, and what it changes in a Brazil room
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
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.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in Brazil.

02 / Specification
One specification sheet, the same in every market
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.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

On a Brazil job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / On the ground
What decides the build-up in Brazil
- 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.
- The housing stock
Concrete frame with block infill and hard floors. Apartment towers share slabs and walls, and impact noise between floors is the common complaint.
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 / Conditions
Durability in Brazil, before acoustics is discussed
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.
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 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 | Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.
06 / Before you buy
The things worth knowing before you place the order
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
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 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
Do you manufacture soundproofing materials in Brazil?
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.
Why would a Brazil build-up differ from anywhere else?
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.
Does Brazil weather shorten the life of this material?
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.
When would material land on 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 will soundproofing materials not do?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
How is the order packed and what is the minimum?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.

Drawings in, BOQ and a delivered date out
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
