FEMA P-737, Vents Technical Fact Sheet #8

The Vents Technical Fact Sheet provides information about ways to avoid windborne embers, convective heat, and radiant heat entering exterior vent openings, which can lead to the ignition of interior building components and contents. Guidance pertains to both new and existing buildings. Note: this is an excerpt from FEMA P-737, Home Builder's Guide to Construction in Wildfire Zones (released in September 2008). This content needs to be verified by an Authority Having Jurisdiction to align with current local codes and building standards.
