Planning a custom home or a new multifamily development? Ensure compliance with California Building Code Chapter 7A by incorporating BrandGuard’s Flame-Resistant Gable End Vents into your design. These vents install just like standard models – but come equipped with a triple-layer defense system to help safeguard structures against wildfire exposure.
Installing BrandGuard’s retrofit fire- and ember-resistant gable end vents. Just insert the appropriately sized vent into the existing opening where the old vent was removed. Secure it using the recommended screw fasteners and seal it with exterior-grade clear caulking, rated with a minimum 30-year warranty for long-lasting protection.

Step 1: Measure and Prepare
Measure the width and height of the existing vent opening to select the correct size. If replacing an old vent, remove horizontal slats as needed. Clean the vent surface with a vinegar wipe, then prime and paint the baffle side and screws using exterior-grade products. Allow to dry completely.

Step 2: Cut and Seal
Cut the vent opening into plywood or siding if needed. Apply a bead of exterior-approved clear or paintable caulking (minimum 20-year warranty) behind and around the flange of the vent to ensure a secure, weather-resistant seal.

Step 3: Install and Secure
Insert the vent with vertical baffles facing outward and mesh facing inward, ensuring the bottom slope is correctly positioned. Use a level for proper alignment. Secure with galvanized self-drilling screw in all corners and every 4 inches. Finish with a final bead of caulking around the outer edge for a clean, sealed fit.
Compare vent models by size, airflow, material, and compliance ratings to find the right fit for your project.

The essential questions, answered.
Home hardening is a critical factor to improve the survivability of structures during wildfires. All homes have vulnerable “point of entry” that must be sealed to avoid hot embers and fire from entering the structure. Home ventilation is essential from an energy saving point of view, however in case of a fire nearby, there is a risk of hot embers finding their way into your attic, basement, garage, etc. BrandGuard has patented a unique system to keep embers from entering your house. Our design consists of multiple line of defense:
BrandGuard Vents resists the intrusion of flame and embers into your attic through the building’s vents, thus protecting your home from dangerous flying embers created by wildfires.
Standard Vents do not offer any protection against flying embers and fire.
Baffles have long been used in commercial kitchens as a way to prevent stovetop fires. We have redesigned them to help keep flames, dangerous burning embers, and radiant heat out of your home during a wildfire. Baffles provide immediate protection during a wildfire from the very first second of exposure.
Another reason baffles are better is because they provide protection from driving rain, snow, and rodents. Our vents have passed stringent driving rain tests in Hurricane labs in Florida keep heavy driving rain out at even 140mph! Rodents are unable to chew or squeeze through our vents like they do with regular mesh vents, making them an excellent option for pest control!
BrandGuard Vents are equipped with a propriety material (intumescent) which expands in case of fire. The thermally activated strip expands up to 30 times its original thickness, sealing off the vent completely. This is an extreme measure to make sure that fire doesn’t penetrate the home.
Yes, BrandGuard Vents will work with you and your needs to create a custom fire prevention vent for your project.
BrandGuard Vents are installed like any traditional vent with the same footprint. Our line of retrofit fire Vents can be easily inserted over existing vents without any damage to the structure. They are held in place by applying appropriate screw fasteners. They can also be installed from inside the attic. Please see our installation instructions.
