US 2015/0082704 A1 · ROLL-UP DOOR SEAL

Abstract

A roll-up door seal arrangement includes side seals, an upper seal and a lower seal to completely seal the periphery of a roll-up door when the door is in a closed position. The seals are sized and adapted to assemble to a standard roll-up door frame without a separate or dedicated frame structure. The seals provide redundant sealing surfaces, positioned to cooperate with both the door and door frame, which ensure an effective and durable fluid tight seal between the cargo space enclosed by the roll-up door and the ambient environment. The seal may be produced by extrusion from a flexible, weather resistant material such as EPDM, thereby providing a low cost solution for sealing roll-up doors having industry standard door frame constructions. The seal is firmly engageable with the door frame, such that the seal may be installed with little or no use of secondary fixation.
