Old-growth Canadian cedar 'at risk from Kiwi importers'SUPPLIED Ken Wu with an ancient Canadian red cedar. The hard cedar requires little treatment as a fashionable cladding, although for general construction builders rely more on cheaper plywood and pine treated with chromated copper arsenic. Cross laminated timber was generally less toxic because it was treated with boron, while cedar and heat-treated pine were the least. Another alternative to chemically-treated wood, or cedar, was heat-treated pine, used by Abodo Wood founder based in Queenstown, Daniel Gudsell. Gudsell said it was tough in the hot and cold climate and an aesthetically pleasing alternative to imported Canadian cedar cladding, popular for new houses in the Queenstown area.
