Eave Vents

The Vent That Protects

 Our eave vents are fire-resistant, with intumescent coating that closes at very high (flame) temperatures and ember catching mesh. Eaves are the undersides of your roof that extend beyond the walls of a building, an area commonly directly over decorative plants and vegetation.

That’s why our fire resistant eave vents are especially recommended (and in many cases required by California Builder Code in Chapter 7A) for the Wildland Urban Interface! To effectively cool the attic outside air needs to circulate through it. In the evening when excess heat is stored up inside the attic’s insulation, it’s critical to quickly release that heat for the night to consequently save on cooling and venting costs.
