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.

Is BAUX PVC free?

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

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.

Do you have any local representatives?

Yes we do.

What is the cost of your products?

We offer a specific price for each project. Please contact any of our International Representation or BAUX directly to receive a quote.

How much BAUX do we need to soundproof the room?

It is not so easy to give a straight answer on how much material you need in order to create a good acoustic environment in a room. It is a quite complex knowledge and ideally a sound expert should visit each location to provide expertise advice.
However, one rule of thumb is that “full damping” is achieved when the amount of “sound dampening material” within a room (textiles, chairs, curtains, Baux tiles, people etc.) correspond to at least 80% of the floor area of the room. If the floor area for example is 50 square meters you should have 40 square meters damping material (all together). Note that this rule of thumb is only applicable if the room is large, i.e. the total floor area is larger than the total wall area. This is a perfect situation but you can get good results with smaller amounts also.
Where you put the damping material in the room is of less matter. So it’s ok if you want to cover only one wall and/or only partially cover another wall – the complete amount of damping material is much more important than where to place it.

Can BAUX be used outdoors?

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. 

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

How much sound does BAUX absorb?

BAUX wood wool is rated as a C-absorbent. BAUX is well equipped to absorb human voice frequencies (between 2000-4000Hz) and is therefore often used in public spaces, offices and schools. With an additional sound absorbing cassette on the back of the tiles, BAUX is rated as an A-absorbent. Contact us for advice on your project.

What is the NRC (noise reduction coefficient) rating of BAUX?

The NRC rating of BAUX is 0,5. It is in other words rated as a B-absorbent. However, if you add an additional cassette with an incorporated sound blanket on the back of the material BAUX is rated as an A-absorbent. We also deliver those cassettes. Contact us for advice on your project.

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.

The BAUX Acoustic products has been tested by Intertek Testing Services NA Inc. for compliance with the applicable requirements of the following criteria: ASTM E84-13a TEST FOR SURFACE BURNING CHARACTERISTICS OF BUILDING MATERIALS (UL 723, UBC 8-1, NFPA 255) with the following test results:
