Eave Vents

Eave vents built to protect.

Eave vents are meant to provide airflow into the attic space underneath the roof. To effectively cool the attic, outside air must provide proper circulation. In the evening, when excess heat is stored up inside the attic’s insulation, it’s critical to quickly release that heat for the night to consequently save on cooling and venting costs.

Eaves, the undersides of your roof, extend beyond the walls of the home, an area that commonly hangs directly over decorative plants, vegetation, and other combustible material, creating high fire danger from wind-blown embers.

Vulcan Vents make
fire-resistant eave vents.

Our noncombustible, corrosion-resistant eave vents are equipped with an ember-catching wire mesh screen complete with an intumescent coating that self-closes at very high temperatures when wildfire is near. 

Vulcan Vents do not use airflow-interrupting baffles, resulting in more venting per square inch for the net free area.

Use EverKem Fire Caulking

  1. We recommend using EverKem 814+, intumescent fire caulking with all installation of Vulcan Vents.
    • Our round eave vents are the exception: EverKem 136, mortar based caulking should be used when mounting hardware isn’t an option and flanges are minimal.
  2. INSTALLATION: Prior to installing the vent, run a bead of EverKem behind the nailing flange to ensure an air tight seal where the vent meets the building material. This ensures that no gaps are present between the vent and your building material where flying embers might enter!

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.
