EverKem Fire Stop 814

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!

Soffit Applications: Flange Styles

These installation examples showcase various flange styles and how they can be used to layer into an enclosed eave application. Our continuous vent is extremely versatile, with various widths and flange options for your particular job. Below are only conceptual examples. Your particular application may vary. Our continuous vents can be cut in the field using a cold-cut chop saw and married end to end for a near seamless finish.

*We recommend using EverKem 814+ fire caulking along the nailing flange for maximum protection.

installed continuous fire safe vents

Your home’s ventilation system
should help defend from wildfire.

New building codes require vents to be made with fire-resistant, anti-corrosion material. We can help. Proper attic ventilation will help with airflow, and Vulcan Vents will help your home protect itself from ember attack, combustion and flames!

Providing necessary attic ventilation,
but self-closing when it matters most.

Our fire and ember-resistant continuous vents for soffits provide the needed ventilation into attic space down the entire length of the soffit, roof ridge, or balcony. 

Vulcan Vents are ideal for new construction in various materials and retrofit kits are available for existing continuous vents on the home. Strip vents such as ours do not use airflow-blocking baffles, resulting in more venting per square inch. Our continuous vents for soffits, roof ridges and balconies feature a stainless steel ember screen and intumescent, honeycomb matrix that closes in the event of high heat.

It’s time for your home to protect itself.

 * For coastal environments, copper, stainless or powder coated finishes are highly recommended. *

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.
