Kebony is beautiful wood recommended by leading architects. It is sustainable, durable and requires no maintenance beyond normal cleaning. Kebony’s performance has been proven in a variety of applications including decking and cladding.

Developed in Norway, the Kebony technology is a patented, environmentally friendly process, which enhances the properties of sustainable softwoods with a bio-based liquid. As a result the wood’s cell structure is permanently modified to adopt premium characteristics:



    with enhanced and strengthened cell structure

  • Refined & Beautiful

    develops a natural patina after exposure to sun and rain

  • High Resistance

    against fungi, rot and other wood destroying micro-organisms

  • Safe & Toxin-Free

    no toxins or harmful impregnation substances

  • Eco-Technology

    bio-based liquid used for Kebony technology

  • Sustainable Sources

    raw material only from sustainably managed forests, all suppliers hold certificates


Our timber is the right choice of material for external, above-ground applications (e.g., decking / terrace, cladding / facade and roofing) where durability, environmental friendliness and low demands on maintenance are important. Kebony is produced from sustainably sourced lumber and bio-based chemical input. The chemicals are polymerised to a stable solid inside the wood fibres, yielding a stable, hard and durable wood material. The wooden boards can be processed with normal hardwood tools and machinery.

Kebony Character boards are not intended for further machining of their surfaces. Kebony Clear boards may be sanded, brushed, planed and profiled without negative effects on durability.

All benefits of Kebony wood

Real wood

We offer high-quality, real wood. No wood/plastic composite – Kebony wood is all organic. We are proud to keep the wood real, and the only change is that we permanently enhance and strengthen the wood’s cell structure.

Refined & beautiful

Kebony offers clear and character grade wood. Both show superior properties while differing in look. One is smooth and silky; the other is rustic and knotty. All Kebony woods have a deep brown colour that will turn to a silver-grey patina over time. The speed of this greying process depends on exposure conditions and type of application. Intense exposure to sunlight and precipitation will accelerate the greying process. Normally, the greying will happen gradually over a few months. This change in appearance has no effect on decay resistance or other technical product properties. Surface treatment with oil, stain or paint will reduce the greying effect or change the colour of the installation.

All Kebony products may be surface coated in cases where retaining the original colour as long as possible, or changing the colour and appearance using paint, is desired. When surface coating is applied, the directions from the coating manufacturer should be followed closely.

Maximum hardness

Thanks to the Kebony® technology, we are able to increase the wood’s hardness to levels of the best hardwoods. Kebony Clear timber products show a Brinell hardness (N/mm2, EN 1534) of 59 to 41, while Teak has a significantly lower hardness of 34. Heat-treated Ash, for instance, shows a hardness level of 30.

Outstanding stability

The Kebony process significantly increases the dimensional stability of the wood. However, Kebony is still a natural product in which there will be some swelling and shrinkage due to changes in relative humidity.

Maximum swelling across the board, from completely dry to complete water saturation, could be up to six percent of the board width for Kebony Character and four percent for Kebony Clear. Swelling of untreated wood in the same conditions will be about eight percent of board width.

Guaranteed long life

Our lumber is ideal for all outdoor decking / terrace and cladding / facade applications thanks to its stellar Durability Class rating (EN 350). All Kebony Clear timber types have a durability class rating of one, which is the best. Kebony Character has a durability class rating of 1-2, which is still excellent. The reason is that Kebony Character contains some heartwood, which is untreatable and therefore has a slightly lower durability class (only treated sap wood).

Low maintenance

Kebony is a low maintenance lumber material that does not require any additional treatment beyond normal cleaning, which was particularly pleasing for many terrace owners. Removal of deposits of dirt, sand and other particles is simply done with a brush and water.

High resistance

Kebony is highly resistant to decay, fungi, insects and other wood-destroying microorganisms. That’s why we are able to offer an outdoor lifetime warranty against rot for 30 years for all Kebony products in above-ground usage.

Safe & toxin-free

Kebony is not toxic to humans or the environment, neither in use nor when disposed of as waste. That’s why Kebony is often selected for kindergarten decking as children will have direct contact with the wood. The wood does not splinter and contains no toxins or chemicals, nor does the wood get too hot in summer.

Waste from Kebony boards can be disposed of and recycled in the same manner as untreated wood. Kebony can be burnt like untreated wood, and will not release any other smoke components than those released when burning untreated wood.


Kebony wood has no harmful effects on the environment. Production of Kebony is based on a liquid extracted from bio-waste and our factory produces to the most environmentally firendly standards. In the waste disposal phase, Kebony can be treated as regular, untreated wood.

All goods delivered by Kebony are Swan Eco-labelled. The Swan is the official Nordic Eco-label, introduced by the Nordic Council of Ministers. The Swan Eco-label's vision is a sustainable society in which future generations can benefit from the same conditions and opportunities as we do today. An important step towards this vision is, with the help of eco-labelling, to help consumers choose the most environmentally friendly products. The Swan logo demonstrates that a product is a good environmental choice

Sustainable resources

The raw materials for Kebony are acquired from commercially managed forests with large timber harvests. All our suppliers hold certificates guaranteeing the origin of their timber.

Kebony is FSC®-certified. The Forest Stewardship Council® (FSC®) works to improve forest management worldwide, and through certification it creates an incentive for forest owners and managers to follow best social and environmental practices. FSC® provides a connection between the forest and the end user, ensuring that products with the FSC® label uphold principles and criteria that adhere to the highest social and environmental benefits and considerations.
