Panel Moderator: Timothy Reinhold, Ph.D., P.E., IBHS Senior Vice President of Research & Chief Engineer Panelists: Stephen Quarles, Ph.D., University of California Cooperative Extension and IBHS Wildfire Consultant, and Timothy Smail, Program Lead for Resilient Programs, Savannah River National LaboratoryTRANSCRIPT
Ember Threat
• Roof Covering
– Noncombustible Covering • Debris free is the key – Roof Lines (complex vs simple roof)
– Gutters – Reentrant Corners
• Openings
– Vents, Garage Doors, Windows
Ember Exposures
Inspect and maintain (repair) bird stops
Debris underneath “gutter guard”
Ember entry through vents
Soffit and Eave area Ridge
Through-roof
Radiant and Direct Flame Contact Threat
• Vertical Wall – Combustible siding and windows
– Potential interaction with other components on the wall (windows, eave, deck, etc.)
• Topography – Slope – Setback
• Fire spread to the building – Fence, gazebos, etc.
– Vegetation management , continuity of fuels
Firewood pile ignited. Radiant exposure to side of house.
Looking down slope from the deck
WPC, not 7A compliant
7A compliant
Combustible Decking
Fence attached to combustible siding
Can’t forget the area immediately next to the building
Thanks for your attention!
