DENVER — Johns Manville said it will make “a significant investment” toward expanding capacity at its Defiance, Ohio, manufacturing facility.

The Defiance Crescent News reports company officials have said the expansion is valued at $50 million. The company reportedly revealed the project cost in seeking a local tax abatement.

In a press release, Johns Manville said the expansion will allow it to increase production of its fiberglass pipe insulation products, Micro-Lok HP and Micro-Lok HP Ultra.

“We are investing in our mechanical insulation business to meet increasing customer demand for our market-leading fiberglass pipe insulations,” said Mary Rhinehart, president and CEO of Johns Manville. “Our decision to make this investment is an intentional step that positions JM to support our customers in a growing industry.”

JM will begin the capacity expansion project early this year and anticipates the completion of the first new production line in 2020.

“Thanks to the support of our customers, we have seen continued growth in this business since we rebuilt the Defiance pipe insulation plant in 2007,” said Bob Wamboldt, president of JM’s Insulation Systems business. “The growth is a result of market demand and, more importantly, demonstrates a distinct preference for JM’s pipe insulation, Micro-Lok HP and HP Ultra.”

Mike McCann, the mayor of Defiance, said the pipe expansion will benefit the city.

“We are excited that Johns Manville has continued to support our community by investing in its business here,” McCann said. “Naturally, JM’s presence is good for the local economy, and the positive influence JM has on the people and families who live in Defiance is incredibly valuable.”

Jim Swift, the Plant Manager in Defiance, will lead the expansion project.

“JM has been part of the Defiance community for more than 60 years,” Swift said. “We are excited to create more jobs as part of this expansion and to continue supporting community organizations. Our employees have done an excellent job in driving the success of our pipe insulation, and we will continue to focus on providing a consistently high-quality product for our customers.”
