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.
