Wildfire-Tested & Code-Compliant V2 Vent Offers Home Hardening Solutions That Resist Ember, Heat, and Flame Intrusions

V2 Vent features a two-stage defense mechanism that addresses the vulnerability of regular vents when under direct wildfire threat.

Loomis, California, United States, October 8, 2026 -- In wildfires nationwide, 90% of home losses come from ember intrusions, not direct flame. Strong, gusty winds lift more embers into the air, carry them farther and faster, and increase ignition risks. In Zone 0, access points such as attic or crawlspace vents can allow embers or flames to enter and ignite combustible materials inside homes.

FireStorm Building Products offers a comprehensive range of wildfire defense solutions for homes and structures in WUI and fire-hazard-severity-zone communities. Its flagship product, V2 Vent, combines ventilation performance with enhanced ember and flame intrusion resistance for effective wildfire protection.

V2™ Vent is independently tested to ASTM E2886/E2912 and listed for both horizontal and vertical applications, supporting their use in wildfire-prone construction and retrofit projects. With its high net-free ventilation area, the product is optimized to promote effective everyday airflow that helps reduce moisture-related problems. Additionally, the product has also been tested to ASTM E119 for 1-hour fire performance.

"What most homeowners do not realize is that a vent screen and a wildfire vent system are designed around completely different threat models. A screen is designed to block insects. A wildfire vent system is designed to respond to conditions that a screen was never built to face sustained ember pressure, radiant heat, and the possibility of direct flame contact," said Nate Oliver, Director of Marketing & Technology, FireStorm Building Products. “Because most standard screens have not been tested for vent resistance to ember entry and flame penetration under simulated wildfire conditions, there is no third-party performance data to verify how they behave in an ember attack.”

Standard mesh vent screens, including common 1/4" and 1/8" hardware cloth, function as passive and permanently open barriers. Typically constructed from plastic, these mesh components can ignite under radiant heat, eliminating their protective function when wildfire conditions are most severe.

In WUI zones, vent selection should be based on tested and listed performance, not product appearance or general "fire resistant" labels. The distinction between passive screening and active defense represents a fundamentally different design objective. V2 Vents are designed for ember resistance, flame penetration and ventilation performance from the outset, rather than treating wildfire protection as a restriction layered. V2 Vents breathe like a vent should and offer protection where it matters most.

"Unlike passive screening, V2™ Vent is an engineered wildfire vent protection system that addresses specific, documented failure modes, allowing for a comprehensive home hardening strategy that addresses all vent locations, secondary gaps, and roofline vulnerabilities," added Oliver.

V2™ Vent are engineered around a two-stage defense mechanism that directly addresses what standard screening lacks. In the first stage, the passive ember protection comprises a fine stainless steel mesh that resists ember-sized particles entering the vent under normal operating conditions while maintaining full airflow through the opening. As stainless steel resists melting and ignition under wildfire heat exposure, this layer requires no activation and functions continuously throughout its lifecycle.

Behind the stainless mesh, V2™ Vent incorporates an Active Flame Defense layer featuring an aluminum honeycomb core coated in intumescent material. When exposed to radiant heat around 450°F, the intumescent coating expands, gradually closing off the vent opening as the temperature rises..

V2™ Vent by FireStorm Building Products provides an effective solution for protecting buildings against wildfire embers, heat, and flames while maintaining essential ventilation. Designed with a stainless-steel ember mesh and heat-activated V2 Matrix, the vents help prevent wind-driven embers from entering vulnerable areas and automatically restrict heat and flame penetration during extreme conditions.
