Do you provide glue or screws?

Yes! You can order Pattex glue directly from us and we can help you calculate how much you need based. Glue is the easiest and cheapest way to mount BAUX wood wool panels and wood wool tiles. If you’d like to purchase the glue yourself, we recommend a standard fixing glue like Casco Superfix, Loctite or Powergrab.

If you’d prefer to install your BAUX wood wool products with screws, we recommend that you talk to a local craftsman to ensure you use suitable screws. We recommend painting over the screw heads with touch up paint, which we provide free of charge.

You can learn more about how to install BAUX here.

Can I repaint my installed acoustic wood wool panels?

Yes, with great care, it is possible to repaint BAUX wood wool tiles and panels. We recommend spray painting to maintain their acoustic performance.

Are recycled materials used in BAUX wood wool products?

There are no recycled materials in BAUX wood wool products because the wood wool fibers need to be of a certain length to create the open structure that generates the functional requirements of BAUX products. If you want to learn more about our production standards – visit BAUX sustainability.

How do BAUX work to reduce environmental impact during production?

We aim to create the lowest possible environmental impact across our whole material chain – from the original raw material to production, delivery, installation, usage and recycling or re-usage of products. We continue to make progress and continuous improvements towards this goal. Forests are PEFC and FSC certified and timber is collected close to the factory to minimize environmental impact. Entire logs are used in production and waste from all stages of production is ground down and reused for new products or used to heat our factory. Read more about certificates and sustainability here.

How do BAUX select suppliers?

Sydved AB has been BAUX’s wood supplier since the start in 2013. They were selected as a single wood supplier for several reasons. Firstly, Sydved has sustainable procedures and FSC and PEFC certification. Secondly, the forest where the wood for BAUX products is harvested is in close proximity to the factory. Read more about and see certificates here.

Cementa, our cement supplier, was selected due to its focus on sustainability and its close proximity to our factory. Cementa is a large company with a great deal of experience in construction.

Can BAUX products be used in BREEAM projects?

Yes, BAUX products are well suited to BREEAM projects. BREEAM does not certify products, but BAUX wood wool is compliant with BREEAM and generates ‘scores’ for different areas of evaluation. These areas include substances, emissions (VOC) and responsible purchase. You’ll find more information about BREEAM in the BAUX here.

Can BAUX products be used in LEED projects?

Yes, BAUX products are suitable for LEED projects. LEED does not certify products but BAUX wood wool is compliant with LEED, who generate ‘scores’ for different areas of evaluation. You find more information about LEED and certificates here.

How do I install BAUX wood wool in the ceiling?

BAUX has not yet established standard procedures for ceilings, so this has to be solved case by case, preferably with the help of a local engineer. However, based on previous projects where BAUX products have been used on ceilings, we typically recommend that you to use screws and then paint the screw heads. If you need more support please contact us!

Do BAUX recommend certain installers?

BAUX has not yet appointed certified installers. Please contact your local representative for more information and recommendations.

How do you maintain BAUX wood wool products?

BAUX wood wool products can be cleaned with a vacuum cleaner without being harmed. Use a brush attachment and apply light pressure on the BAUX tiles or panels.

Do BAUX wood wool products shed dust?

When installing BAUX wood wool products, they can shed some dust. After the installation is complete, they should not shed at all. BAUX products are allergy certified in Sweden and when installed they are easily maintained. Read more about our certificates and environment.

Can I order different sizes of wood fibers?

No, you cannot order different sizes of wood fibres. BAUX products are designed to maintain the best possible acoustic performance in one beautiful design.

Why are acoustics important?

A well-designed acoustic environment can improve productivity and have a positive effect on health and wellbeing. Noise affects workers in four ways: physiological (sudden and unpleasant noise can increase heartbeat), psychological (sound can either calm us down or raise stress levels), cognitively (how we perceive things which affect our learning capacity) and finally behaviorally (noise can make us more aggressive and less helpful). If you want to learn more – contact us!

What is NRC?

NRC stands for ‘Noise Reduction Coefficient’. It’s a rating system that explains how much sound an acoustic product can absorb. NRC ratings range from 0 to 1. An NRC rating of 0 means that the product absorbs no sound. An NRC rating of 1 means that the product absorbs all of the sounds. In other words the higher the NRC, the better the product is at soaking up the sound.

The thickness and density of a product are two factors in calculating an NRC value. An acoustic product with a .95 NRC rating means that 95% of the sound in the space is absorbed, while the other 5% is reflected. Want to learn more? – Contact us! 

How much acoustic wood wool do I need?

To give an exact answer, we recommend you consult an acoustics expert who can visit and make precise calculations. BAUX can offer advice, or consult remotely. Please contact BAUX HQ or your local BAUX sales representative.

How should I interpret the sound graph in the catalogue?

The vertical axis is the absorption coefficient, which indicates the level of absorption for every given sound frequency. 0 means that no sound is absorbed and 1 means that all sound is absorbed.

On the horizontal axis, you have the sound waves and frequencies (HZ). The higher the frequency of a waveform, the higher the pitch of the sound you hear. The graph shows the level of absorption on different frequencies.

BAUX wood wool is well equipped to absorb human voice frequencies (between 500-4000Hz). NRC (Noise Reduction Coefficient) is an average rating of how much sound an acoustic product can absorb. Here is the full catalogue!

Are BAUX wood wool products sound isolating?

BAUX wood wool products are not designed for sound isolation, but rather for sound absorption. Sound isolation (reducing noise from one room to another) is achieved through density – the higher the density of the material the better the isolation. Please note, sound can travel through ventilation systems or through a wall via vibrations.

Can I install BAUX wood wool in a music recording studio?

Absolutely! Just note that BAUX wood wool products absorb sound in the room, rather than isolating the sound. See the question “Is the BAUX material sound isolating?” for further information.

What transport company do BAUX use?

Our delivery partners in Europe and Asia are DB. Schenker and LEMAN. From the end of 2018, LEMAN will act as our primary delivery partner.

We ship “DAP Intercoms”, meaning that the seller is responsible for arranging carriage and for delivering the goods, but the buyer is responsible for import clearance and any applicable local taxes or import duties.

If you wish to arrange your own transport, you can purchase BAUX with Ex Works (EXW). This places minimum responsibility on the seller, who merely has to make the goods available, suitably packaged, at the specified place, usually the seller’s factory or depot. The buyer is responsible for loading the goods onto a vehicle (even though the seller may be better placed to do this) and for all export procedures, onward transport and all costs arising after collection of the goods.

How can I order BAUX wood wool samples?

Firstly, check to see if you have a local representative. If so, then please contact your representative for samples. If you don’t have a representative, then you can send us an email at: [email protected].

Contact us and provide us with the NCS codes of the six colours you prefer (see our colour scheme), your complete shipping address plus recipient name and telephone number. You can also visit `how to order´ for more information.

Is BAUX PVC free?

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

What functional benefits does BAUX wood wool products have?

BAUX acoustic wood wool products have many functional benefits. Our wood wool products absorb sound, regulate moisture, accumulate heat, they’re also fireproof, and they have low VOC.

BAUX acoustic wood wool products are effective in absorbing human voice frequencies (500-4000Hz). When BAUX wood wool (25 mm thick) is mounted directly onto a wall, the material performs at NRC 0.40 and Alpha-w 0.30 (class D).

BAUX acoustic wood wool products are moisture resistant and they even out air humidity by absorbing or emitting moisture into the ambient air, creating a better indoor climate. The high pH value discourages mould or rot, and BAUX acoustic wood wool products can be used in bathrooms and swimming pool areas. When using wood wool in shower rooms, BAUX products should only be fixed to the ceiling and not walls.

BAUX acoustic wood wool products naturally accumulate heat releasing it into the ambient air when the air temperature falls. This contributes to lower energy costs, a reduced environmental impact and a comfortable indoor climate.

BAUX acoustic wood wool products are A-Classed in surface burning tests by Intertek (ASTM-E84) and classified according to European classification for building products, DIN EN 13501 with rating B-s1,d0. For more information and certificates visit Sustainability and Certificates.

Is BAUX wood wool products fireproof?

BAUX acoustic wood wool products are fireproof and A-Classed in surface burning tests by Intertek (ASTM-E84) and classified according to European classification for building products, DIN EN 13501 with rating B-s1,d0.

How do I install BAUX Acoustic wood wool 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 commonly used for BAUX Panels. BAUX can provide touch up colors for the screw heads.

How much does one BAUX wood wool tile weigh?

BAUX Wood Wool (25 mm thick) weighs approximately 11 kg/m2.

Is BAUX Acoustic Wood Wool suitable for sensitive environments?

Yes. Wood wool is suitable for sensitive environments like schools or hospitals. It is possible to vacuum clean the material or dry it with a cloth. You can read more about our sustainability and read more about our certificates here.

How much sound does BAUX wood wool 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 performs NRC 0.60 and Alpha-w 0.50 (class-D) when mounted directly 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.

What is BAUX Acoustic Wood Wool made off?

BAUX acoustic wood wool is produced from wood wool made from sustainably managed forests, cement, and water. Combining these natural materials creates several functional benefits in one ingenious combination.

Wood Wool fibres retain heat, provide insulation and offer excellent sound absorption. Cement, a proven building material, binds the wood wool to provide strength, moisture resistance, and fire protection. BAUX Acoustic Wood Wool products also have very low VOC.

Can I install BAUX wood wool in kitchens or wet rooms?

Yes. BAUX Wood Wool is moisture-resistant and the high pH-value of BAUX products discourages mould or mildew, making it rot resistant. BAUX wood wool products are suitable for kitchens, bathrooms and swimming pool areas.

When installing BAUX wood wool products in shower rooms, tiles or panels should only be mounted on the ceiling and not on the walls.
