Vulcan Vents obtained a listing from California State Fire Marshall for use in the Wildland Urban Interface wildfires, under category 8165 of the Building Material Listing Program.

Vulcan Vents have also successfully passed the ASTM Wildland Urban Interface (WUI) testing standards for ember and flame intrusion (ASTM E 2886 and ASTM E 2912). These standards, officially adopted and published, are applicable throughout the entire United States for any wildland fire area in which new or existing homes exist or are being built.

In addition to passing the WUI fire testing standards, the Vulcan Vents have also passed the one (1) hour fire test under the ASTM E 119 one (1) hour fire test standard. This standard is applicable in property side yard setback issues where a one (1) hour fire rating is being required.

Vulcan Vents are products of Vulcan Technologies, a partner of Firefree Coatings. Their vents use a Firefree proprietary intumescent product. They are the only vents that meet both the WUI and the one (1) hour fire test standards for the exterior of buildings while providing the proper amount of ventilation to attic and crawl spaces in building structures. The vents are easy to install in both new and retrofit conditions, are made of high quality materials and quality construction.
