Abstract: A sealing system for sealing the periphery of a door relative to a frame. The sealing system includes a multi point finger seal having at least three fingers of differing height and spacing so that a first finger may contact the door and contact of the first finger and s second finger is precluded. A second finger is sized and spaced from a third finger so that a free edge of the second finger abuts the base of the third finger. A security seal is located at the bottom of the door and includes a security flap biased into the door, wherein a cam on the frame engages the flap upon closure of the door to urge the security flap toward the floor.
