The 2010 National Building Code of Canada now references the 2008 edition of the CSA standards for treated wood which has a new approach to classifying treatments for different end uses. Topics to be covered: Treated wood requirements in the 2010 NBCC, other situations where treated wood may be needed, overview of CSA O80 Series Wood Preservation (industrial preservative treatments, residential preservative treatments), understanding use categories 1 through 5A (Table 1 in CSA O80.1), products and their use categories for specific exposures (Table 2 in CSA O80.1), preservative retention requirements for sawn products (Table 10 in CSA O80.1), preservative penetration requirements for sawn products (Table 5 in CSA O80.2), selecting the appropriate wood species for stability, strength and treatability, selecting the appropriate preservative, pre/post treatment conditioning, third party quality assurance, appropriate and inappropriate product substitution and on-site care and handling of treated wood to maximize durability.
Paul Morris – Group Leader: Durability and Protection FPInnovations Paul’s group of four scientists and six technologists is responsible for meeting client needs for research in short-term protection of wood during harvesting, transport and storage, and long-term durability in service. The latter includes durability by nature, durability by design and durability by treatment. Paul has twenty seven years experience in wood preservation research since obtaining his PhD from Imperial College of London University. He has authored or co-authored over 250 papers, technical reports, contract reports and other publications. As a member of the International Research Group on Wood Preservation he maintains awareness of new technologies under development throughout the world. He also participates in collaborative research and test method development. His areas of expertise include test methodology, international building codes and wood preservation standards, treatment of Canadian wood species, and factors affecting the durability of wood products. Paul is also an adjunct professor in the Department of Wood Science at the University of British Columbia.
