Quad Smart Vent Insulated Block Wall 32-1/2" x 16, Gray - 1540-150202E-1540-0239-GRY
For situations where a sealed crawlspace is being utilized in a floodplain, flood protection is still required and the Insulated FLOOD VENT series is the perfect fit for those applications. This series is used for a garage or conditioned space where flood protection is required but air ventilation is not desired.
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.
The flood door contains a 2” styrofoam core that has an R-value of 8.34. There is also a felt weather stripping that lines the entire vent frame helping to keep the enclosure as insulated as possible.

I wish I had ordered the insulated vents the last time, they are so much better than the open vents. The quad looks great and not heavy. Hardest part is removing the cinderblocks.
