Dormer Vents

The Vent That Protects

Important for proper cooling of the attic dormer vents are a common entry point for embers. Low profile dormers are often called ‘eyebrow vents’. Half-round dormers like the one below often are often called ’round’ dormers.

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 Vents are designed with embers and flames in mind.
