Johns Manville Announces Additional Capacity for Microfiber by April 2011

Johns Manville (JM), a leading global manufacturer of energy-efficient building products and engineered specialty materials, today announced they are bringing online previously shutdown capacity in order to better serve the overall market demand for Microfiber.

“For over 150 years, JM has been committed to meeting the needs of our valued customers,” noted J.P. Blanchard, Global Manager of the Filtration and Specialty Nonwovens Business. “We invested in bringing the additional capacity online in order to better serve our customers’ needs as well as the growing demand in the market for our world-class products.”

The capacity will be out of the company’s Waterville, Ohio facility and the new assets will immediately increase the supply of some products by as much as 35 percent. Furthermore, additional capacity is available that will be activated in a second phase as demand dictates. The primary markets for Microfiber are High Efficiency Air Filtration and Absorptive Glass Mat Battery Separators.

“JM is committed to serving our customers and has dedicated substantial resources to underscore our commitment to the Microfiber’s business as the markets return,” noted Bob Wamboldt, Vice President and General Manager of Engineered Products North America. “This is the right time to make investments in additional capacity and fulfill the needs of the market and our customers.”

“The current schedule is for capacity to be running in April with supply available to our customers soon thereafter,” noted Blanchard. “We are committed to growing with our customers and to supporting their global operations now and for the long-term.”
