Exploring the self-extinguishment mechanism of engineered timber in full-scale compartment fires

This project investigates the self-extinguishment mechanism of Cross-Laminated Timber (CLT) at a full-scale in order to establish design criteria for the re-safe use of CLT in tall-timber buildings.

The aim is to provide a methodology to establish criteria for self-extinguishment of Engineered Wood Products at a full- scale, considering complexities such as delamination failure, encapsulation failure, and rate of exposure of timber surfaces.

The research will evaluate fundamental self-extinguishment properties such as critical external heat ux and pyrolysis rate, in order to determine whether fully exposed timber compartments may achieve self-extinguishment if delamination is controlled.
