Installation Quick Tips to consider when ordering:
  1. Install Brandguard Vent with baffles facing out and the mesh facing inside the attic into the existing opening.
  2. Gable Vents: Install with baffles vertical. Ensure the “slope” is at the bottom
  3. Foundation Vents: Install with baffles Horizontal
  4. Undereave/Soffit Vents: Install with baffles horizontal. These vents are “ok” to install with the mesh facing out and baffles facing in. Performance will not be affected.
  5. Continuous Soffit vents: Must pre-order varying lengths, cannot cut in field. If nailing to Rafters, order Flange back
  6. Dormer Vents: Install with baffles vertical with Slope at bottom

Materials: Brandguard vents come standard as 26 gauge G90 Galvanized material with ¼” mesh.

Custom: Upon special request, we can also provide the vents in Bonderized, Copper, Stainless Steel, Galvalume, and pre-painted or with 1/8” mesh. Additional charges WILL apply.

Determine the size, types and # of vents for the opening areas (w and h) that you will need.

Prior to ordering, you need perform a “Ventilation Calculation” to determine the number of vents required to meet the building code for proper ventilation. Brandguard Vents can assist with this. For attics, In most areas, including California, If using at least 20% of Undereave/Soffit vents with the remaining balance of exhaust vents at least 3 ft above the eave or cornice vents, you may use a 1/300 ventilation calculation- even with a radiant barrier. Please confirm with your local building code.

  • Intake Vents: Undereave/Soffit Vents, should be about 50% of the total sq in required.
  • Exhaust Vents: Gable End, Dormer Vents, should be about 50% of the total sq in required.
  1. Total Sq ft of attic = A
  2. Divide A by building code: A/ 300 = B total # of sq ft required for building
  3. Convert to sq in: B x 144 = C Total # of sq inches required for building
  4. Divide C in half to calculate intake and exhaust vents: C/2 = D and E
  5. D = Intake Vents     E= Exhaust Vents
  6. Divide D and E by the NFVA of selected Brandguard Vents to get to qty needed to meet code


Brandguard Vents are designed to be a part of fire prevention and ventilation for your home. Failure to install properly will negatively impact overall performance and void warranty protections.
