This fifth generation $100 million family-owned company had its origin in Krummussbaum, Austria, manufacturing refractory bricks and mortar. From its inception in 1891 through 1983, the Rath organization developed and produced refractory brick, castable and moldable refractory, as well as vacuum shaped products of alumina fiber. In 1986, Rath built a facility for the production of alumino silicate fiber in Mönchengladbach, Germany, and in 1989 began using a sol-gel process to produce alumina fiber capable of withstanding temperatures up to 1800°C. Rath currently has production facilites in Austria, Germany, Hungary, and the United States.
