018 - Engineered timber with Danny Hopkin

Engineered timber is on a trajectory to become the construction material of the future. However, on that pathway there stands the fire issue. Wood burns, it is inevitable. This is something we must accept, and learn to work around. Common approach – determination of a char profile and the “healthy” section has its limitations, especially when applied to CLT products in which one could expect the glue line failure. And all of this is the topic of my todays discussion with Dr Danny Hopkin of OFR Consultants. Danny did his PhD on the subject of timber in fire and has participated in multiple interesting research projects on this topic. He is currently working with the Structural Timber Association on a STA-SIG CLT project on unravelling the fire behaviour of CLT, with its experimental part carried at the ITB in Poland.
