Charred Accoya for Timber Cladding, Fins and Panelling

ITI Timspec's Charred Accoya uses Shou Sugi Ban, an ancient Japanese architectural technique used to preserve wood by charring the surface with a hot flame producing a beautiful dark finish with exquisite snakeskin appearance and texture.

The process involves charring the wood, cooling it, cleaning off any soot or burnt debris on the surface, and then finishing the boards with an oil. When fire is applied to wood boards, the burning process creates a thin layer of carbon on the wood surface, which is what we see as burnt wood. This carbon layer protects the interior wood in very much the same way that stains or sealants would.

Shou Sugi Ban enhances the durability and is a natural means of preserving wood without chemicals, paints, and other surface treatments. It is very low maintenance and naturally resistant to insects as well as moisture damage.

The Shou Sugi Ban process is environmentally friendly and doesn’t contribute to harmful pollution. There are no chemicals present in this cladding to potentially leach into the environment and it’s entirely safe for homes with children.

Accoya holds industry leading environmental credentials. The exceptional durability of Accoya is warranted for a minimum life of 50 years above ground and 25 years in-ground.  

Board lengths range from 1.8m to 4.8m
