A roller door sealing system including at least one sealing member carried on the curtain, and disposed adjacent the end of the curtain attached to the roller, and a seal engaging member supported adjacent the curtain. The sealing member and the seal engaging member are disposed such that the sealing member engages the seal engaging member and seals the space between the curtain and the seal engaging member as the curtain approaches the doorway-blocking position. The sealing function provided by the sealing member or members only occurs as the door approaches the door blocking position.
