Vulcan Vents manufactures fire- and ember-resistant ventilation systems designed to protect homes in wildfire-prone areas. Their vents use a stainless steel mesh and a honeycomb matrix with intumescent coating that expands under heat, sealing the vent to block flame and embers while maintaining airflow under normal conditions. Vulcan’s product line includes continuous, eave, gable, soffit, foundation, and retrofit vents—all compliant with California’s Chapter 7A code and tested to ASTM E2886 / E119 standards.
