What Is Kebony Wood?
Kebony is not a wood species but a patented Norwegian technology that permanently transforms sustainable softwoods into high-performance building materials rivaling tropical hardwoods. Through a process called furfurylation, a bio-based liquid derived from agricultural crop waste is impregnated into the wood's cell walls, permanently hardening and stabilizing the material.
The result is Scots Pine or Radiata Pine that's been fundamentally altered at the cellular level — harder, more dimensionally stable, more decay-resistant, and with a rich dark brown color that goes all the way through the board. Kebony achieves Class 1 durability rating (the highest) and comes with a 30-year warranty.
Kebony has been adopted by leading architects worldwide for premium outdoor projects — from The Scream museum in Oslo to waterfront boardwalks and luxury resort decking. It offers tropical hardwood performance with significantly better sustainability credentials, using FSC-certified softwood and a bio-based modification agent.

Kebony Premium Decking
Kebony decking offers tropical hardwood-level performance from a sustainable, bio-based product with a 30-year manufacturer warranty. The furfurylation process creates deck boards with Class 1 durability that resist rot, decay, and insect damage as effectively as the best tropical species. Kebony's rich dark brown color creates a warm, premium aesthetic on residential and commercial decks, while the through-body treatment means any scratches or surface wear maintain the same color. The boards work with hidden fastener systems for a clean, screw-free surface. For architects and homeowners who want the look and performance of tropical hardwood decking with a clear sustainability advantage, Kebony represents the cutting edge of wood technology.

Kebony cladding has been specified by award-winning architects worldwide for museum facades, waterfront developments, and luxury residences. The modified wood's exceptional dimensional stability means siding boards resist warping and cupping through extreme weather cycles, keeping joints tight and facades looking sharp. The dark brown color weathers to an attractive silver-gray patina if left untreated, or can be maintained with annual UV oil application. Kebony's FSC certification and bio-based modification process make it one of the most environmentally responsible choices for exterior cladding. From The Scream museum in Oslo to luxury resort facades, Kebony cladding proves that sustainability and premium aesthetics are fully compatible.

Kebony has been extensively used for waterfront boardwalks, marina decking, and public waterfront installations across Europe and increasingly in North America. Its Class 1 durability rating means it handles constant moisture exposure, salt air, and heavy pedestrian traffic without deteriorating. Municipal and commercial projects value Kebony's 30-year warranty, which provides long-term cost certainty for public infrastructure budgets. The modified pine handles fasteners well, works with standard decking installation systems, and provides a comfortable, splinter-resistant walking surface for bare feet. For public waterfront projects where durability, sustainability, and aesthetics must all be world-class, Kebony has become a go-to specification.

Maintenance & Care
Kebony requires minimal maintenance. Its modified cellular structure provides built-in protection against decay, rot, and insect damage.
Natural Weathering
Kebony weathers to an attractive silver-gray patina naturally. Many owners prefer this look. No treatment is required for structural protection.
Color Maintenance
To maintain the dark brown color, apply a UV-protective oil 1-2 times per year. This is purely cosmetic — the structural properties remain unchanged regardless of finish.
Cleaning
Clean with mild soap and water or a deck cleaner. Pressure washing on low setting is safe. Regular cleaning prevents surface mildew.
Important Considerations
Premium Pricing
Kebony costs more than standard treated lumber — comparable to mid-range tropical hardwoods. The 30-year warranty helps justify the investment.
Limited Availability
Not stocked at typical lumber yards. Order through specialized dealers or directly from authorized distributors.
Newer Technology
While backed by extensive testing and a 30-year warranty, Kebony has a shorter real-world track record than century-proven tropical hardwoods like Ipe.
