Shou-sugi-ban, the age-old Japanese practice of burning Japanese cypress, is an important influence in modern exterior timber cladding design. The process involves using an open fire to leave timber with a charred, blackish finish. Nowadays, industrial blowtorches can also be employed to replicate this effect.
Applying black timber stain is another way to blacken timber. Especially when used for multi-depth cladding like Expression Cladding, blackened timber has the ability to simultaneously convey rustic charm while accentuating the contemporary lines of a structure.
House D, Italy
This private house designed by PAUHOF Architekten features a facade (as well as atrium-level walls) covered with flamed oak cladding. The charred vertical cladding adds even more drama to an already strikingly sculptural silhouette.
House at Walk Barn Farm, UK
By Charles Barclay Architects, this weekend prairie house with a “bat attic” (literally) stars an exterior with pine “board on board” vertical cladding. Stained black, the timber facade allows the vacation home to form a discrete bond with the landscape.
Aggressive wire brushing, when performed professionally, will abrade the lighter portions of the timber grain and render its patina darker, approximating other timber-blackening outcomes but leaving behind a more characteristic appearance of outdoor weathering. Cladding systems like Woodform Archietctural's Expression Cladding are perfect for outdoor use.
