Enclosed Eaves Without Compromise: Fire Protection & Ventilation Can Coexist
When it comes to protecting your home from wildfires, enclosing your eaves is one of the smartest upgrades you can make. But we often hear the same concern from homeowners: “If we enclose the eaves, will my house still get enough ventilation?”
The short answer is yes and here’s how.
What Are Eaves, Anyway?
Eaves are the part of your roof that extends beyond your home's walls. They're more than just a decorative detail—they serve an important function. Eaves help direct rainwater away from the house, and they usually contain vents that allow air to flow into your attic, helping to keep your home cool and dry.
However, these open, vented areas can also be vulnerable during wildfires, allowing embers to enter the attic and ignite a fire inside the home. That’s why enclosing eaves has become a key part of wildfire home hardening, especially here in California.
Why Ventilation Still Matters
While closing off those vulnerable openings may seem like the right move for fire protection, airflow is still essential. Proper attic ventilation helps regulate heat and moisture, which is especially important in our warm, dry climate. Without it, you risk issues like mold, warped wood, and reduced energy efficiency.
Fire Protection with Smart Vents
Here’s the good news: when we enclose eaves for fire safety, we don’t seal everything off completely. Instead, we install specially engineered vents that allow air to circulate under normal conditions, but automatically seal shut under extreme heat.
These vents are designed to:
✅ Allow proper attic ventilation
✅ Resist intrusion from embers and flames
✅ Maintain airflow year-round without compromising fire safety
Here’s how they work:
Material: The core of these vents is made from high-grade stainless steel metal. This gives them strength, durability, and the ability to withstand years of exposure to the elements without rusting.
Intumescent coating: The vent’s secret weapon is a heat-reactive coating known as an intumescent layer. This coating stays dormant under normal conditions but swells up rapidly when exposed to high temperatures, like during a wildfire. As it expands, it seals off the vent openings and blocks embers from getting through.
Design: These vents are carefully engineered with fine mesh screens and strategically placed baffles to prevent debris, pests, and sparks from entering—even before the coating activates. The design allows passive airflow while maximizing fire protection.
A Safer, Smarter Home
By combining eave enclosures with ember-resistant vents, you get the best of both worlds: improved fire protection and continuous airflow. It’s a smart home upgrade that supports your family’s safety and your home’s long-term health.
