US Patent 10385611 Flood vent having a panel

According to one embodiment, a flood vent panel includes a plurality of insulation pieces positioned together, and a panel frame surrounding the plurality of insulation pieces. The flood vent panel is configured to be coupled to a frame positionable into an opening in a structure, so as to at least partially block a fluid passageway through the opening in the structure. One or more of the plurality of insulation pieces are configured to uncouple from the flood vent panel when at least a predetermined amount of pressure is applied to a portion of the flood vent panel by one or more of a fluid or an object carried by the fluid, so as to reduce an amount of blockage of the fluid passageway provided by the flood vent panel.
