Abstract

In a recent urban fire in Itoigawa-city, Niigata, Japan, structures were exposed to firebrands and it was reported roofing assemblies were ignited, which led to loss of entire structures. Roof tiles are fabricated using non-combustible materials yet the sheathing materials, under the roof tile, are often combustible. In this study, the physics of potential ignition mechanism of Japanese style tile roofing assemblies exposed to firebrands was explored. Debris was placed under tiles to simulate aged construction. After 20 minutes of firebrand exposure, firebrands were observed to penetrate under tiles and the debris was ignited, resulting in ignition of sheathing materials.
