FireStorm® EmberMesh™ and EmberVents™ meets or exceeds the following 2024 IWUIC.
FireStorm® EmberVents™ are made out of 304 Stainless Steel making it the best choice for those who want a durable material.
Firestorm® EmberVents™ are designed for defense! They are resistant to flames, embers, and corrosion, and are able to withstand exposure to the elements without degrading or breaking down.
Firestorm® EmberVents™ are designed with a small aperture to keep embers out, including debris.
The small aperture size prevents embers from passing through the mesh, which is a major concern for those who live in W.U.I areas.
If the existing vent obstructs the installation of the new vent screen, carefully remove it. If the vent is recessed and does not interfere, you can leave it in place.
Measure the dimensions of the rough opening where the new vent will be installed. Ensure accurate measurements to select the correct size vent. Choose one of our vents that is big enough to ensure that our mounting flange sufficiently over laps your building material and allows you to securely fasten our vent to your building, leaving no gaps for possible ember penetration.
If you have chosen one of our available colors, you can skip this section and begin mounting your vent. If you’ve chosen our Bonderized finish option, you can paint your vent directly without the need for primer. Masking off the vent face is optional. Our black powder coating nearly disappears once the vents are installed. Select the appropriate fasteners based on the type of siding on your home. This could include screws, nails, or other fasteners suitable for your siding material.
Position the new vent over the rough opening and secure it using your selected fasteners. We recommend fastener spacing of 6”. Ensure the vent is firmly attached and properly aligned with the siding. For uneven surfaces, more fasteners may be needed. If you find screwing directly through the metal frame difficult, you can pre-drill guide holes at each corner of the metal frame with a metal drill bit. This will make screwing the fasteners much easier.
Ensure that your vent is securely fastened to your siding and that there are no gaps bigger than 1/16” that could allow for ember intrusion.
For installation instruction on our full vent assemblies, such as dormer vents, gables vents, and 2-way vents, consult your local building professional.
