BLOCK HOLE
VENTS

IMPORTANT AIRFLOW NOTES:
Flame & Ember resistant vents naturally provide less airflow than regular, unprotected vents and Vulcan Vent airflow ratings (NFVA) are approximately 91% that of the same size standard 1/4" screened vent and are listed within each products description.  In retrofit application you may need to increase the number of vents currently in use to maintain proper ventilation.

Please consult your local building codes and/or engineer to determine proper airflow/venting requirements and the number of vents required for your project.

Standard sizes show below. Custom vents in other shapes & sizes also available, please call for pricing.
