How embers reach the structure through vents
Attic, gable, soffit, foundation and crawlspace vents are designed to move air through the home to control moisture and temperature. During a wildfire event, that same airflow can carry embers past a damaged or oversized screen and into concealed spaces where stored materials, insulation and framing may ignite.
Categories of vent solutions
Available options may include corrosion-resistant metal mesh retrofits, complete vent replacement and ember-resistant products designed for wildfire-prone areas. Vulcan Vents is one manufacturer in this category. Product listings, approved applications and installation requirements vary by model and opening.
Choosing what fits the home
The appropriate product should be selected based on the vent location, existing construction, airflow requirements and current local requirements. Proper ventilation and moisture control must be maintained. East Bay Home Hardening offers Vulcan Vent installation and retrofit options as part of home-hardening work.
Maintenance
Any vent solution should be inspected periodically. Debris, damage from wildlife and normal weathering can all reduce effectiveness.
