Abstract
A roll-up door assembly including a plurality of door panels; a pneumatic seal apparatus having an elastic membrane of an elongated tube disposed around a perimeter of the trailer door so as to be adjacent to the plurality of door panels, wherein pressurized air is injected into the pneumatic seal apparatus to expand the elastic membrane and to apply an outward force against multiple sides of the plurality of door panels, wherein applying the outward force against the plurality of door panels on multiple sides keeps the plurality of door panels as a single unit such that substantially less air flows through the plurality of door panels than prior to the application of the outward force to seal the trailer door.
