Won-Door Corporation

Won-Door Corporation, founded in 1962 by the Smart family, has built a reputation as an industry pioneer in folding partitions and fire-rated doors. Starting with the world’s most durable acoustically rated folding partitions, the company advanced to develop the first accordion-style fire-rated horizontal sliding door — the Won-Door FireGuard. This innovation was rigorously tested and approved in 1977, setting new standards for fire safety.
