When a large roller shutter door is opened large atmospheric losses will occur. Airius units simply stop the outside air from penetrating into the building as far, and more importantly once the door is closed the building recovers at a much faster rate.
A perfect example of this would be aircraft hangers where the entire wall opens up in the building. Even with this aircraft hangars achieve some of the highest levels of savings, ranging from 35% right up to 60%, with little to no process heat to help.
