Fire resistant dormer vents

Important for proper cooling of the attic, and a common entry point for embers.

Our half round dormer vents are attractive, long lasting and fire resistant. Use vertical dormer and gable vents in combination with horizontal vents for proper ventilation. Vertically oriented vents may be more prone to ember attacks, so Vulcan Dormer Vents are designed with embers and flames in mind.
