Did you know:
Household vents are known to be vulnerable to ember attacks. The Vulcan Vent was designed with embers in mind! Our foundation vents use a baffle-free design to encourage air to circulate freely under your floors in the summer. This circulation reduces the risk of mildew, mold and rot from water condensation under your structure.
NFVA: Net free ventilation area. This indicates the amount of open ventilation, measured in square inches.
