Wildfire architecture requires attention to small building-envelope details. Roofs, eaves, soffits, walls, decks, windows, gutters, and vents all influence how a structure responds to embers, radiant heat, and flame contact.<\/p>\n
For architects and specifiers, vents are a key coordination point. They must support airflow and moisture management during normal conditions while reducing wildfire vulnerability at openings into attics, crawlspaces, and enclosed roof areas.<\/p>\n
Vent selection should not be left until the end of a wildfire-prone project. Vent type, net free vent area, material, corrosion exposure, wall or roof assembly, fire exposure, and code context all affect the final specification.<\/p>\n
Wind-blown embers can travel ahead of the flame front and reach buildings before direct flame contact occurs. If embers enter through ordinary vents, they may reach combustible materials inside attics, soffits, dormers, gables, or crawlspaces.<\/p>\n
Wildfire-ready vent design should address ember blocking, heat and flame response, airflow, durability, and installation fit.<\/p>\n
Ventilation supports moisture control and building performance. A wildfire vent should not solve ember exposure by simply sacrificing needed airflow. Instead, the design should balance net free vent area, intake and exhaust paths, and tested wildfire performance.<\/p>\n
V2 Vents provide the highest airflow on the market for wildfire vent applications while supporting ember blocking and active flame defense.<\/p>\n
California wildfire design discussions often refer to Chapter 7A. Current projects should also account for the California Wildland-Urban Interface Code, including CWUIC Chapter 5 where applicable, plus the requirements of the authority having jurisdiction.<\/p>\n
V2 Vents are tested and listed to ASTM E2886 \/ E2886M \/ E2912 for flames, embers, and radiant heat.<\/p>\n
Eave and soffit vents:<\/strong> Coordinate with overhang depth, intake airflow, roof framing, and ember exposure below the roof edge.<\/p>\n Gable and dormer vents:<\/strong> Account for wind exposure, wall assembly details, flashing, and attic exhaust needs.<\/p>\n Foundation and crawlspace vents:<\/strong> Review grade conditions, debris exposure, corrosion environment, and moisture management requirements.<\/p>\n Continuous vents:<\/strong> Coordinate long ventilation runs with cladding, soffit, roofline, and installation sequencing.<\/p>\n V2 Vents is a FireStorm Building Products line manufactured by New Cal Metals. The corrosion-resistant stainless steel ember mesh helps block ember intrusion, and the V2 Honeycomb Matrix expands at critical temperature to help form a protective barrier against heat and flames at the vent opening.<\/p>\n New Cal Metals has been manufacturing wildfire defense products for over 17 years. V2 Vents are available for multiple vent applications and can support both new construction and retrofit specifications.<\/p>\n Explore V2 vent categories<\/a>, review Codes and Compliance<\/a>, or Build With Us<\/a> for specification support.<\/p>\n","protected":false},"excerpt":{"rendered":" Wildfire architecture should integrate ember-resistant vents early in design.
