About the Topic: 
Shou Sugi Ban – Exploring the Characteristics and Aesthetics of Charred Wood as a Cladding Material

The technique of fire treating wood cladding is receiving growing attention as a means of adding a unique visual design to a building fa ç ade. Originating in ancient Japan, Shou Sugi Ban has been used for centuries as a means of protecting wood siding from insects, rot, and fire. Today, it is being used as a high-end designer product.

While attending BCIT’s Architectural and Building Technology program, Jason, Michael, and Preston investigated the weatherability of charred wood siding to better understand its performance in a coastal climate.  Accelerated weather testing was performed using different combinations of char depth, wood species and finish treatments. With collaboration from FP Innovations, RDH Building Science, and Intertek their capstone research project was awarded first place by BCBEC in 2016.

This presentation is intended to be a high-level overview on the use of Shou Sugi Ban, the outcome of their research, and the benefits and drawbacks of this alluring product.
