Abstract:

The present study is concerned with investigating the ignition of ceramic tile roofing assembles (Spanish tile roofing) to a controlled firebrand attack using the Firebrand Generator. Current standards exist to test ignition of roofing decks to firebrands by placing a burning wood crib on top of a section of a roof assembly under an air flow. The dynamic process of multiple firebrands landing under ceramic tiles/gaps as a function of time is not taken into account. The results of a parametric study on the ignition propensity of ceramic tile roofing assemblies under a firebrand attack using the Firebrand Generator installed inside the Fire Research Wind Tunnel Facility (FRWTF) at BRI is presented and discussed.
