What is it?
The practice of Shou Sugi Ban started in Japan in the 1700's and is used on a wide range of traditional town houses and modern buildings.
The technique sounds very simple, but is actually fairly labour intensive and dangerous. In our own efforts to perfect this product, we've gone through a rigorous research and development programme. This has enabled us to understand how the timber reacts to the process and how to get the best results and finishes.
So what is Blackclad?
Blackclad is a process of charring the exterior exposed faces of profiled timber weatherboards. Blackclad is not a system but we can provide a weatherboard with a Shou Sugi Ban finish which can be utilized in a New Zealand Building Code Acceptable Solution application.
The predominant applications comprise of bevel back weatherboard on a cavity system, shiplap or rusticated weatherboards on a cavity system, Board and Batten on a cavity system as well as non-profiled boards used as a weather screen.
The timber we use & recommend is a sustainably grown Larch (Larix Sibirica) which is grown in Russia and Siberia. This timber has both FSC and PEFC Certification and has a natural Class 3 Durability unfinished.
The board is burnt up to the point that it flashes. It is then doused in water. No further treatment is required and the board colour is a blue black with a slight silver sheen. The board can be finished with an oil which takes the silver sheen away and becomes jet black.
The board is burnt up to the point that it flashes then doused in water. The board is then scrubbed with a hard nylon brush. This process removes all the burnt cellilose and produces a brown/copper coloured finish with a sheen.
The Dragon's Skin
The board is burnt up to the point that the surface crackles and looks like the skin of a reptile. It is then doused in water. No further treatment is required and the board colour is a blue black with a slight silver sheen. The board can be finished with an oil which takes the silver sheen away and becomes jet black.
The Shou Sugi Ban technique has been incorporated in a number of contemporary residential & commercial buildings by architects around the world. This is a small sampling.
The ehouse experiment, Auckland
This weekend retreat sits majestically amongst Redwood trees and Kanuka. The Blackclad rain screen helps sit the contemporary structure amongst its Kanuka setting. The finish is ‘The Scrub’ option and has three widths fixed in a random format. Read about this project at www.icr.co.nz.
