The Problem
With conventional vent designs, structures are extremely vulnerable to radiant heat sources, direct flame impingement, and most problematic of all, lofted fire brands that can begin to threaten a home well before the head of the fire reaches the structure as well as long after it has passed
During a wildfire, fire brands are a significant cause of fire damage, attacking the structure at its most vulnerable points...the vents. Fire embers can cause ignition and continuous fire spread deep into urban areas. Research shows that while homes are destroyed by the passing front, the majority of structural damage is caused by fire embers well before or after the front of the fire.
Key Considerations for Fire Suppression Personnel During An Urban Wildland Interface Fire Are:
■ Large numbers of simultaneously exposed structures
■ Rapid involvement deep into residential areas
■ Overwhelmed fire protection capabilities
■ Total loss of ignited structure
■ Massive damage to entire neighborhoods well out of designated threat areas in a matter of hours
The Problem with Conventional Vent Designs
Conventional vent designs offer little to no defense against an approaching wildfire. Laboratory research shows that fire enters into the attic space unimpeded within seconds of exposure. This illustrates an important point: structures burn from the inside out during wildfires and, if we want to improve a structure’s chances of survival during that exposure, we need to improve the ability for the structure to resist ignition.
Blue Ribbon Committee
The Governor’s 2003 Blue Ribbon Fire Commission determined that existing designed attic and roof ventilation increased the structure’s vulnerability to fire and that 1/4 screening was ineffective against dangerous embers. When required by CBC chp. 15 and 7a, roof and attic vents shall resist intrusion of flames and embers (CA State Marshal 8604B2.1).

The Solution
TM
Brandguard Vents has developed a patent pending design that has met the needs of both building and fire officials. Using a baffle-front design that acts as a heat sink, preventing damage from radiant and direct heat sources, the baffle also forces the outside air to change directions, robbing the heat from dangerous embers and directing them to a sloped base that deposits the remains to the outside of the structure.
This is the first vent of its kind to address and meet the fire prevention and safety needs that code officials have been calling for. This is also the first baffle vent of its kind to be tested by leading
research officials.

How It Works
Brandguard Vents baffle-front design is made to prevent most causes of fire damage during rapidly spreading wildfire.
The baffle acts as a heat sink and reduces the threat of fire brands entering through a structure’s vent openings.
The baffle design changes the flow of air and creates an effective heat trap, preventing damage from radiant heat sources.
The design has comparable net-free vent area to similar traditional vents
and allows for sufficient exchange of moist air, thus preventing mold issues. Responds to the needs of both safety and building officials that call for a vent design that will help prevent fire ember damage.
■ Patent pending design acts as a heat sink
■ Resists fire ember and direct flame intrusion
■ Helps prevent other sources of fire and smoke damage
Conventional metal louvered vent with metal screen allows flame, embers, and radiant heat sources to enter.
Brandguard VentsTM improve a home’s chances of surviving by redirecting flame, embers, and radiant heat sources.
