When most homeowners think about wildfire threats, they picture towering flames moving across a landscape. However, research has shown that one of the biggest dangers to homes isn't always the fire itself—it's the embers.
Wind-driven embers can travel miles ahead of a wildfire, landing on or around homes and igniting vulnerable areas long before the main fire arrives. These tiny burning particles can enter through vents, collect beneath decks, become trapped in gutters, or find their way through damaged screens and openings.
Fortunately, homeowners can take proactive steps to reduce these risks through a process known as home hardening.
What Is Home Hardening?
Home hardening refers to a series of improvements designed to make a home more resistant to wildfire exposure. These upgrades focus on protecting vulnerable areas where embers can enter or ignite combustible materials.
Common home hardening measures include:
• Upgrading vents and ventilation openings
• Protecting windows and doors
• Screening under-deck areas
• Installing ember-resistant gutter protection
• Reducing combustible materials near the home
• Using fire-resistant building materials where possible
While no single product can make a home fireproof, each improvement can help slow fire spread and reduce ignition opportunities.
Why Embers Are Such a Serious Threat
During a wildfire event, embers can be carried by strong winds and deposited directly onto homes. Once there, they search for vulnerable entry points and fuel sources.
Some of the most common areas where embers can cause problems include:
Vents and Attic Openings
Attic and crawlspace vents are essential for airflow, but they can also provide a pathway for embers to enter a structure. Once inside, embers can ignite insulation, dust, or other combustible materials.
Windows, Doors and Patio Enclosures
Traditional fiberglass screens can melt and deform under extreme heat, allowing embers to penetrate. When compared to traditional metal insect screens, Phifer EmberScreen features excellent outward visibility, a proprietary coating for increased safety, and a tighter mesh for both ember and insect resistance.
Under Decks
Decking systems often create partially enclosed spaces where leaves, pine needles, and debris can accumulate. Wind-blown embers that enter these areas may ignite combustible materials beneath the deck.
Roof and Eave Gaps
Roof assemblies, eaves, and gutter systems can trap embers and create ignition points that are difficult to detect until a fire has already started.
A New Tool for Home Hardening: EmberScreenTM by Phifer
As homeowners look for practical ways to strengthen their home's defenses, EmberScreen by Phifer offers an innovative solution designed specifically to address ember intrusion risks.
Engineered for ember defense, EmberScreen helps reduce the likelihood of dangerous airborne embers entering vulnerable openings throughout the home and is a relatively simple upgrade that can be incorporated into both new construction and retrofit projects.
Designed to Help Reduce Fire Risk
EmberScreen is designed for use in areas where embers commonly enter structures, including:
• Windows
• Doors
• Patio enclosures
• Vents
• Eaves
• Gutter covers
• Under-decking areas
• Roof assembly openings
• Patio and outdoor kitchen enclosures
By helping block ember entry, EmberScreen can play an important role in a broader home hardening strategy.
A Low-Profile Upgrade with Long-Term Benefits
One of the advantages of EmberScreen is that it delivers added protection without dramatically changing a home's appearance. Its low-profile design blends into both traditional and modern architectural styles while providing durable, corrosion-resistant performance.
Unlike many ember-resistant screens that use thick, visually intrusive mesh, EmberScreen offers excellent outward visibility, allowing homeowners to enjoy scenic views while adding another layer of protection against wind-driven embers. This makes it especially well-suited for homes in wildfire-prone mountain, coastal, and other view-oriented locations where preserving visibility is an important consideration alongside ember protection.
Available in stainless steel or aluminum vent mesh and proudly manufactured in the United States by Phifer Incorporated, EmberScreen is backed by more than 70 years of screening innovation and expertise.
EmberScreen Stainless Steel
For applications requiring maximum durability and versatility, EmberScreen Stainless Steel delivers enhanced strength and long-term corrosion resistance. It is the preferred choice for windows, doors, patio enclosures, under-deck screening, and other exposed applications where both ember protection and excellent outward visibility are desired.

EmberScreen Aluminum Vent Mesh
Designed primarily for vents and other ventilation openings, EmberScreen Aluminum Vent Mesh provides dependable ember resistance while maintaining the airflow needed for proper ventilation. Its corrosion-resistant construction makes it an excellent choice for many residential home hardening applications.

Advanced Protection with a Proprietary Coating
Unlike standard screening products, EmberScreen features a proprietary coating applied over either stainless steel or aluminum mesh. This extra layer helps enhance ember resistance while maintaining long-term durability.
Combined with EmberScreen's tightly woven mesh, the coating helps create an additional layer of protection as part of a comprehensive home hardening strategy.
Tighter Mesh without Sacrificing Airflow
Protective screening must strike the right balance between airflow, visibility, and ember resistance. EmberScreen is engineered with a tighter mesh that helps reduce ember intrusion while still providing:
• Essential ventilation airflow
• Excellent outward visibility
• Insect protection
• Increased resistance to ember penetration
Whether choosing aluminum vent mesh for ventilation openings or stainless steel for broader screening applications, homeowners can select the product that best fits their project while maintaining the performance needed for an effective home hardening strategy.
Supports Home Hardening Recommendations
EmberScreen was developed to support CAL FIRE's home hardening recommendations by helping address common wildfire vulnerabilities around residential structures.
For homeowners building in wildfire-prone areas, the product also meets the requirements of California Building Code Chapter 7A for ember-resistant venting in new construction.
Tested for Ember Intrusion Resistance
EmberScreen has demonstrated resistance to ember intrusion during controlled ASTM laboratory testing that simulates ember exposure conditions.
While no product can guarantee protection during every wildfire event, testing helps verify performance under standardized conditions designed to evaluate ember resistance.
Protecting What Matters Most
Wildfire preparedness often focuses on evacuation plans and defensible space, both of which are critical. However, strengthening the home itself can also make a meaningful difference. Home hardening is about reducing vulnerabilities before a wildfire occurs.
While no solution can eliminate risk entirely, protecting vents, windows, doors, under-deck areas, and other openings can significantly improve a home's resilience against wind-driven embers. By helping slow fire spread and reducing ember entry points, these improvements may provide valuable additional time for emergency responders to act before a fire starts.
