Fire-resistant vents
help your home protect itself.

The smallest spaces on a home can be the most vulnerable. Wind-blown embers fly for miles ahead of the actual flames, entering the home through attic vents or crawlspace vents. Combustible materials have the potential to ignite, essentially burning the home from the inside out.

Approved and recommended
by the ones that matter most.

Vulcan Vents are California Building Code Chapter 7A- compliant and approved by the State Fire Marshal (SFM). In fact, new homes built in the Wildland-Urban Interface (WUI) in California are required to include ember-resistant vents under Ch. 7A. Vulcan Vents have met the standard requirements under the American Society for Testing and Materials (ASTM) E2886 and sufficiently passed the ASTM E119 one-hour fire test to effectively block ember entry.

Vulcan Vents are used and trusted by construction and insurance companies nationwide for good reason.

What makes Vulcan Vents the #1 fire and ember-safe vent?

How do
fire-safe vents work?

Vulcan Vents are designed for fire protection. Our corrosion-resistant, stainless steel ember mesh blocks dangerous embers during ember attacks long before the fire arrives. When a wildfire nears and the vent reaches critical temperature, the intumescent coating on the honeycomb matrix will expand, creating a protective fire wall. This allows your building’s exterior to do it’s job at resisting ignition!

We called to find out if the Vulcan vents would meet the California ember retardant standards for fire. Nate Oliver took our call and spent nearly half an hour providing us with in depth information, guiding us through their website to view and discuss each alternative and even taking us to another website to view the Vulcan product on it. He discussed different options for installing the vents and the specific type of caulk we needed that also met the fire-wise requirements. Then he guided us to the section where we could download the documentation for our insurers. We came away from this conversation with exactly what we needed and the documentation to back it up. I can't say enough good things about Nate's customer service. His knowledge was remarkable, his eagerness to ensure that we ordered the exact right vent was so reassuring, and we immediately posted the Vulcan Vent information on our neighborhood Facebook site so that others in our fire-prone area can obtain the right products for their venting needs. If I could give 10 stars I would.

After a few months of having the new Vulcan Vents installed in our eaves, I am extremely impressed with the updated design. The 1/8” fine mesh on the outside prevents insects from getting into the ‘honeycombs’ and the 1/4” mesh on the inside adds coverage from attic side to the ‘honeycombs’ without reducing airflow. The ingenious design allowed plenty of airflow to the attic through this past summer, but if a fire were to come our way, it is comforting to know that these same vents will expand and close off, preventing embers or direct flame from being able to enter the attic. A bonus to the design, as you can see in the picture below, is that the thickness of the vent prevents being able to see into the attic and preventing attic insulation from getting pushed up against the outside screen, which somehow tends to happen whenever access is made to attics. Aesthetically and design-wise, these vents provide a solid home hardening solution that is easy to install. These vents are a must in my opinion for any homeowner who has any plants near their home that could generate significant heat during a wildfire. The combination of the 1/8” mesh and the coating that expands and cuts off all airflow into the attic when exposed to radiant heat are the perfect combination to prevent embers, radiant heat, and direct flame from entering the attic space. My experience with this local company (Loomis, California) is that they have excellent customer service and go above-and-beyond to ensure that their customers are satisfied with the quality of their product.
