A door sealing system includes a frame and a pneumatic liner positioned along an inner perimeter of the frame. The liner includes a hollow interior for adjusting it between extended and retracted configurations. A pump is included for selectively inflating the liner and a valve which can be deactivated to deflate the liner. When inflated, the liner fills the gap between the door and the frame and when deflated, allows the door to be opened easily. A sensor is positioned with a cavity in the frame for detecting placement of a latch indicative of the door being opened or closed. A processor then appropriately actuates the pump or deactivates the valve. Accordingly, the seal is inflated when the door is closed and is deflated when the door is being opened.
