Johns Manville Enhances Glass Fiber Nonwoven Line at its Wertheim facility

Johns Manville (JM), a leading manufacturer of nonwovens, today announced its plan for a substantial technical enhancement to a glass fiber nonwoven line at its Wertheim, Germany facility. The project will address the increasing needs and demands of local customers and markets. The enhanced glass fiber nonwoven line is expected to be in production by the end of 2017.

“This investment clearly shows the strong commitment our U.S. based parent company has to the Wertheim plant,” said Heinrich Bein, Managing Director of JM’s German glass plants. “I am proud of the JM employees who have worked hard to make this development possible, and I am proud of the way they support our Made in Germany manufacturing processes on a daily basis.”

Martin Kleinebrecht, JM’s Leader of Marketing & Portfolio Management for Nonwovens in Europe & Asia, said, “Johns Manville has decades of experience in the development and production of glass fiber nonwovens. This line enhancement will help us to further expand our market position.” Kleinebrecht added that JM will use its best efforts to ensure that a reliable supply of goods is available to customers while the construction is taking place.

Johns Manville has more than 65 years of experience in manufacturing glass fiber nonwovens. In 1948, the first trials on glass fiber nonwovens were conducted at the company’s former plant in Coburg, Germany, and production began two years later. The first wet laid glass fiber nonwoven line was inaugurated at the Wertheim facility in 1968.
