Certain example embodiments relate to 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 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. The seal includes one or more perforations therein, causing the seal to breakaway and into pieces if removal is attempted.
