As the wood mid-rise market takes off in Ontario, one challenge designers and builders face is finding the best-priced pre-engineered wood products for their assembly. Another challenge is finding products that will work for that assembly. “A great price can come with no services but on these jobs, you might want something different — a little extra involvement (from your supplier),” said Andy Teasell, engineering and technical services manager for Weyerhaeuser’s Trus Joist. While more design professionals are choosing single layer gypsum board assemblies over two-board systems…, suppliers with technical expertise might illustrate how that single layer system can lead to unexpected costs, Teasell said at a seminar at the Toronto Wood Solutions Fair.
