Vulcan Fire and Ember Resistant Venting

Vulcan Vents are patented exterior vents that prohibit both dangerous embers and flames from entering a structure during a wildfire. Vulcan Vents are the first to be accepted in the CBC Ch7A Compliance Policy by the Office of the California State Fire Marshal (www.osfm.fire.ca.gov).
- Eve & Block Hole Vents
- Gable End Vents
- Foundation Vents
- Soffit Vents
- Custom Vents of almost any shape/size
Vulcan Vents are engineered to:
- BLOCK DANGEROUS FLYING EMBERS from penetrating a structure’s ventilation system. Wildfires generate embers which fly through the air and can result in an ember attack on a structure and a new fire being ignited from the inside. Dangerous flying embers do not penetrate the Vulcan Vent design thereby potentially saving structures which are many miles from wildfire flames.
- PROHIBIT FLAME INSTRUSION through a structure’s ventilation system. Approaching fire generates heat which triggers the Vulcan Vent to close. The vent is coated with a non-toxic Firefree ™ intumescent coating, which expands when exposed to a heat source of approximately 350° Fahrenheit thereby closing the ¼ inch (or smaller) vent openings.
Note: Vulcan Vents come with 1/8" screening on the face, the Vulcan honeycomb in the middle and 1/16" screening on the inside to further protect against ember and insect intrusion past the Vulcan honeycomb. This offers the ultimate in protection while maintaining 91% of a standard 1/4" screened vents airflow!
