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. 

A safe home starts with venting. 

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
 
 
retrofit vents install easily into existing vents

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. 

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).
