Won-Door

Won-Door Corporation, founded in Salt Lake City in 1962, manufactures horizontal sliding fire and security door systems that create open, unobstructed interior spaces while meeting fire protection and building codes. The company's products are installed in diverse building types across North and South America, Europe, Asia, and the Middle East. Won-Door's FireGuard™ horizontal sliding fire doors and DuraSound™ acoustically rated folding partitions enable architects and building designers to maximize architectural vision while maintaining safety compliance. Applications include museums, hospitals, schools, and casinos. In 2021, Overhead Door Corporation acquired Won-Door, expanding its global reach and research capabilities in pedestrian access solutions for fire, security, and sound attenuation.
