Research shows that a FIREWISE prepared house with a surrounding FIREWISE Defensible Space is 85% more likely to survive a wildfire than one that is not prepared.
Understanding fire behavior, especially how hot a fire will be and how long it will be at the building site, will help homeowners and builders decide how defensible a house needs to be, and what actions need to be taken to make the building site more fire-resistive.
Four principal factors are responsible
for structure ignitions:
* Indirect heating by convection
* Firebrands (airborne burning embers)
* Indirect heating by radiation
* Direct flame contact or impingement
