What is BAUX Acoustic Wood Wool made of?

BAUX Acoustic Wood Wool is an environment-friendly, recyclable material made from wood wool, cement and water. The natural components together provide many functional characteristics.

BAUX Acoustic products contains two of the world’s oldest building materials – wood and cement united as cement bound wood wool.

The combination is simple and ingenious. Wood fibre gives the product a heat-insulating, heat retaining and sound-absorbing structure. Cement, a proven and popular building material, is the binder to provide strength, moisture resistance and fire protection.

BAUX Acoustic products are sound absorbant, have high moisture diffusion, high air permeability and the capability of absorbing and releasing water molecules from the air. This allows the exposed BAUX Acoustic discs to even out the relative humidity (RH) in the room. BAUX Acoustic products really have the property that is known as “material that breathes. ”

BAUX Acoustic Wood Wool products have also been tested for emission and shows very low values.

What are the measurements of the tiles/panels?

Our TILES come in two different sizes each, and our PANELS come in one size only. Have a look in our catalogue (starting at page 5) to view all measurements available.

Can I use BAUX in the bathroom?

The material is moisture resistant and does not rot. Therefore it has often been used in bathrooms and swimming pool houses. If using the material in the shower area it should only be mounted in the ceiling, not on the walls.

How do I design the pattern?

You can choose from two different options. Either you can choose one of our predesigned patterns, or you can download our toolkit and create your own.

Is BAUX environmentally friendly?

Yes. The BAUX products contain three natural ingredients: wood wool, water and cement. We are also proud that Baux has been approved by Google in a Leed Green Gold project. All raw materials are collected close to the factory to minimize the environmental impact.

Can I get samples?

Yes you can. We typically provide smaller material/colour pieces in a standard box containing 6 different colours to give a feeling for the material and colours.
Contact us and provide us with the NCS codes of the 6 colours your prefer (have a look at our product page to view the colour options), your complete shipping address plus recipient name and telephone number.

Can I get custom colours?

We can do custom colours and we need the NCS color code (not RGB or Pantone). For larger orders we include custom colouring for free. If you have a smaller order we need to charge extra fees per color since we have certain costs connected to new colours. Test painting must be performed to secure that the paint properly cover the surface.

The material has been used outdoors for decades.  It withstands moisture and does not rot. We recommend using a ledge to protect the material from being exposed to heavy rain.

How does noise affect office environments?

The open plan office trend is not so cost efficient as you might think. Truth is that open plan offices decrease productivity by 66% according to the sound expert Julian Treasure. Taking sound into consideration is consequently key when designing office spaces.

How does noise influence us?

Noise or sound influence us in four main ways: physiological (sudden and unpleasant noise can increase heart beat), psychological (sound can either calm us down or raise the stress level), cognitively (how we perceive things and consequently also our learning ability) and finally behaviourally (noise can make us more aggressive and less helpful). Learn more about this by watching the video The 4 ways sound affect us with the sound expert Julian Treasure. Investing in pleasant acoustic environments has many positive health effects. 

Can BAUX Tiles and Panels be reused?

If screws are used for mounting on the wall or in the ceiling the Panels and the Tiles can gently be removed and reused. If glued directly to the wall with recommended amount of glue used, the Small Tiles can possibly be removed and reused if removed with care. If the Panels & Tiles not can be reused for the project, they can be ground down and reused e.g. as ballast and filling material, moisture absorbent sprinkling, a substrate for running tracks etc.

How do BAUX work with reducing environmental effect in production?

The spruce is collected close to the factory to minimise the environmental impact, further the used spruce is PEFC and FSC certified. In the production, the entire timber logs are used for production, and waste from other stages of production is all grounded down and reused for new products or used for heating of the factory.

Is BAUX PVC free?

Yes. The material contains three natural ingredients: wood wool, water and cement.

Is BAUX fire proof?

Yes, we are A-Classed in surface burning tests by Intertek according to ASTM-E84. Baux is classified according to European classification of building products, DIN EN 13501 and is rated as B-s1,d0

Does BAUX Acoustic Wood Wool withstand moisture?

The moisture-resistant material evens out air humidity by absorbing moisture from or emitting moisture to the ambient air. This contributes to a pleasant indoor climate which is good for both comfort and health. The high pH value also discourages mould and the material is not affected by rot.

How does BAUX Acoustic Wood Wool accumulate heat?

BAUX Acoustic Wood Wool stores heat from the ambient air and emits it when the air temperature falls. This contributes to lower energy costs, reduced environmental impact and a stable and comfortable climate indoors.

How do you install BAUX Acoustic products?

Using glue is the easiest and fastest way to install BAUX tiles. We suggest a standard fixing glue similar to Casco Superfix or Loctite Powergrab. If you don’t like to use glue, BAUX can also provide tiles backed with magnets. BAUX then also supply metal cassettes or thinner sheets that you install on the wall as a backing to the magnetized tiles. The tiles can then be fixed by hand and rearranged according to taste. The cassettes create an air-gap to the wall, thus improving the sound absorbing properties for the installation slightly. If you prefer magnets you should bear in mind that the creative pattern of the tiles must be adapted to match the dimensions of the cassettes and sheets. A third way to install BAUX is to use screws. BAUX can provide touch up colors for the screw heads.

How much does one BAUX tile weigh?

The BAUX Acoustic Tiles and Panels (25 mm thick) weigh approximately 11 kg/m2.

Is BAUX Acoustic Wood Wool suitable for sensitive environments?

Measurements show that emissions from BAUX Acoustic products are extremely low. The strong surface can cope with vacuum cleaning, and use of the product in restaurants and other sensitive environments show that the boards do not emit dust or particles.

Do you deliver BAUX Acoustic products anywhere in the world?

Yes. We deliver BAUX Acoustic Wood Wool products world wide. Depending on where you want us to deliver the tiles the shipping fee may wary. Please contact us for more information and price quotes.

Can I avoid transmission to/from my neighbours?

Our tiles are well equipped to dampen sound reflections within a room thanks to its open structure. However, if you want to avoid noise transmission from- or to a neighbour we do not recommend our tiles.

How much sound does BAUX absorb?

BAUX is well equipped to absorb human voice frequencies (between 500-4000Hz) and is therefore often used in public spaces, offices and schools. BAUX wood wool 25 mm thickness, directly mounted on the wall or ceiling performs NRC 0.40 and Alpha-w 0.30 (class D). The 3D PIXEL product with an even distribution of thicknesses 25/50/70mm perform NRC 0.60 and Alpha-w 0.50 (class-D) when mounted direct on the wall or ceiling. These values increase when mounting BAUX with an air slot between the wall or ceiling and the BAUX material. To reach higher absorption coefficients you can also use BAUX together with a 40 mm stone wool panel (140 kg/m3). Stone Wool 40 mm behind 25 mm BAUX, directly mounted towards a wall or ceiling, together perform NRC 0.95 and Alpha-w 1.0 (class-A). Contact us for details and advice on your project.

How do you recycle BAUX Panels?

Wood wool boards may be ground down and recycled (after magnets are removed and glue leftovers scraped off) and used as e.g. as ballast and filling material, moisture absorbent sprinkling, a substrate for running tracks etc.
