Over the past decade, Canada has been developing regulations to promote the use of cross laminated timber (CLT) and other mass timber products, in a variety of new and larger scale applications. This has required much research and testing to establish standards for structural strength, fire performance, thermal and acoustic behaviour. Large scale testing of CLT panels has generated consistent results and assured scientists that large mass timber buildings can be designed to the standards of life safety and structural stability required by the National Building Code of Canada.
Nonetheless, the perception of some municipal authorities, local fire marshals, building owners and developers does not yet comfortably differentiate between the fire performance of light wood frame structures and those made of mass timber. This same perception is evident in Europe where many Tall Wood buildings are still required to have concrete podiums, stair and elevator shafts.
