Kebony Character Cladding
Scots pine impregnated with furfuryl alcohol — a bio-based chemistry derived from agricultural crop waste — then cured, permanently thickening the cell walls so a fast-grown softwood behaves like a durable hardwood: Kebony quote class 1 durability and use it uncoated, weathering to silver-grey. Character is the knotty grade cut from the whole log. The modification is chemical rather than thermal, so unlike thermally modified timber it adds real fossil carbon in production (+231 kgCO2e/m³) — but the timber’s biogenic store still dominates the declared A1–A3.

Carbon and evidence
Product Evidence
Evidence currently held for the Kebony product record.
Recorded Carbon Result
A1–A3 GWP-total per m³ (570 kg). Negative because 1,050 kgCO2e of biogenic carbon is held in the timber against 231 of fossil emissions from the furfurylation process — roughly double the fossil carbon of the thermally modified pines on this shelf, bought back many times over by the biogenic store. That store is not permanent: C3 declares +1,060 kgCO2e at end-of-life incineration, so cradle-to-grave is close to neutral rather than strongly negative.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.
