These vents are used for a home with a crawlspace or any enclosed area that desires natural air ventilation and flood protection.
Flood Protection
The vent door is latched closed until it comes in contact with flood water. Entering flood water lifts the patented internal floats which unlatch and allow the door to rotate open. This allows the flood water to automatically enter and exit through the frame opening, relieving the pressure from the foundation walls. Certified flood debris clearance is demonstrated with a 3" diameter opening when the flood door is activated.
Ventilation
A bimetal coil automatically opens and closes the ventilation louvers as temperature changes. No electricity is required. The louvers will be fully closed at 35F and fully open at 75F. In the event of a flood the internal floats lift to release the flood door to rotate open and relieve the hydrostatic pressure regardless of the louvers' position, open or closed.
Beautiful Design Starts with a Structurally Sound Foundation. Smart Vent supports Architects with flood venting solutions that combine aesthetics and code compliance with certified performance. During a flood event, poorly protected homes will give way to hydrostatic pressure caused by quickly rising floodwater, crumbling foundations and destroying the structural integrity of the building.
Building Codes and FEMA Requirements state that flood venting is required for homes built in certain flood zones. Provide your clients with unparalleled protection and guarantee them the lowest possible NFIP Flood Insurance Premium by specifying SMART VENTS.
