At York University, our fire research team studies heritage materials and their response to fire. Our focus has been to consider timber and masonry. Doing these studies we are in the midst of preparing revised international guidance for these important structures. More recently the events in Paris have emphasized why this is such a serious topic of research to consider. For the last two years we have focused our efforts to really understanding timber performance, and we have done this by procuring real materials (columns, beams etc) from structures undergoing renovation (adaptive re-use) or sadly demolition. The importance of this study is now even more profound given this weeks events.
