The Insulated FLOOD VENT series is designed for use in conditioned spaces where flood protection is required, but natural air ventilation is not desired.
For situations where a sealed crawlspace is being utilized in a floodplain, flood protection is still required.
Stacker Models are twice as efficient as a single unit, and are a great solution for:
• large amounts of square footage requiring flood protection
• situations where there is not enough wall space to fit single units
