Retrofits
All vents should be built to protect.
Vulcan Vent retrofit kits are available to easily install mesh screening and honeycomb intumescent coating (sold together) on any vent on the house providing the ultimate protection from dangerous embers and flames.Â
A safe home starts with venting.Â
Kits come in a variety of dimensions and can be custom made if necessary. Vulcan Vents retrofit kits include:
- Retrofit Gable End Vent/Eave Vent: Exterior
- Retrofit Half Round Dormers
- Retrofit Gable End Vent: Interior
- Continuous Vent Retrofits
- Soffit Vent/Ridge Vent Retrofits
- Retrofit Half Round Dormers
- VE (Vulcan Eave)
- Subflashing
- The Vulcan Sub Flashcan be used in conjunction with any other manufacturers’ dormer or roof vent and turn it into an ember and fire-safe vent
Â
Â
Protecting the most
vulnerable places on a home.
All vents on a home from roofing to the crawlspace must provide adequate ventilation and protection when it matters most. Vulcan Vents are meant to allow airflow while blocking vulnerable spaces from dangerous embers and flames when fire is near.Â
Baffle-free design
for efficient airflow.
Ember and fire-resistant vents are required under California’s Chapter 7A building codes located in high-risk fire zones otherwise known as the Wildland-Urban Interface (WUI). As such, Vulcan Vents are recommended for homes by the California State Fire Marshal (OSFM).
Vulcan Vent
Features
Honeycomb matrix closing technology with ember-catching screen mesh built into galvanized steel frame
Baffle-free design for maximum airflow (NFVA) to keep your home dry
Designed to meet the new California Building code State Fire Marshal (OSFM) 12 Chapter 7A of the California Wildland-Urban Interface (WUI) fire code program
Passed the American Society for Testing and Materials (ASTM) E2886 to effectively block ember entry
Use EverKem Fire Caulking
- 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.
- 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!

It’s time for your home to protect itself.
 * For coastal environments, copper, stainless or powder coated finishes are highly recommended. *
