Study of Damage to Shutters Exposed to a Vegetation Fire: Definition of Vulnerability Thresholds
ABSTRACT This study examines the fire behavior of wooden, PVC, and aluminum shutters through laboratory and large‐scale experiments. Laboratory tests were conducted using a cone calorimeter to assess the ignitability of the PVC and wooden shutters, focusing on the critical heat flux of ignition, ignition time and critical Flux Time Product (FTP ...
