Embodiments of the invention provide a sealing system configured to provide a sealed boundary between a conditioned and an uncontrolled or separately conditioned environment. In some examples, the sealing system may comprise a door, a conditioning device, and a seal assembly. The door may be moveable between an opened position and a closed position. The seal assembly may be coupled to the door and have an airflow path. When the door is in the closed position, the conditioning device may be configured to direct conditioned air into the airflow path, thereby urging conditioned air through the seal to inhibit undesirable door and/or adjacent surface conditions.

Sealing system for a conditioned door threshold

A roll-up door () with slats () rolled on a reel () with spiral guides () that maintain a tangent between the reel () and the closure plane at the point of entry/exit so as to maintain a perpendicular entry and exit with the side guides () and reduce friction, increase speed, reduce noise and help keep self-aligning end caps tracking correctly. It can also eliminate hinges between slats and permit each slat to be removed independently, without disassembling the other slats.
