Charred
Wood
Timber transformed by controlled fire. A surface sealed against decay, water and insect — preserved for a century without stain or paint.
Minutes to carbonise. Decades to weather.
Yakisugi is the traditional Japanese technique of burning the surface of sugi (Japanese cedar) — today adapted to pine, cedar and larch — to form a protective carbonised crust. The char seals the wood against water, fire, rot and insect, and in its unoiled form needs no chemical sealer.
What arrives on site is timber that has already weathered its first fire, finished in the exact shade and texture your project requires.
*Service-life figure reflects standard industry performance for charred cladding in exterior applications, using Thermowood pine substrate on a properly vented rainscreen. Fire class per EN 13501-1 Declaration of Performance for the Thermowood substrate. Independent test reports and warranty terms available on project request.
The fire does the preserving.
The craftsman only guides it.
Fifteen shades. One raw material.

Select
Grade A kiln-dried species — pine, cedar, hemlock, larch — milled to specification and moisture-balanced to 8 ± 2%.
Char
Intense open flame carbonises the surface in a controlled triangular stack, following the traditional sankaku-gumi method. Char depth is tuned from 2 to 6 mm.
Finish
Water-cooled, then wire-brushed to the exact character — soft matte, rugged texture, or deep-brushed with grain relief.
Install
Shiplap, open-joint, batten-screen or tongue-and-groove profiles on a vented rainscreen cavity.
