Transaction marks expansion of insulation products line to include additional solutions for industrial, commercial and fireproofing applications

DENVER--(BUSINESS WIRE)--Johns Manville (JM), a Berkshire Hathaway company and global building products manufacturer, today announced it has purchased Industrial Insulation Group, LLC (IIG), a manufacturer of insulation for industrial, commercial and fireproofing applications.


IIG was formed in 2002 as a joint venture between JM and The Calsilite Group. JM previously owned a minority interest in IIG, but will now operate the company as a standalone LLC wholly owned by JM. IIG’s product line complements JM’s portfolio of insulation products, allowing JM to offer an even broader continuum of solutions that meet the insulation requirements for any project.

“Expanding JM’s interest in IIG is another way we are addressing customers’ needs by offering the industry’s most complete line of insulation products,” said Todd Raba, JM chairman, president and CEO. “IIG has a consistent track record of product performance, in keeping with the quality our customers expect from Johns Manville. We look forward to exploring opportunities to build on IIG’s strong market position and expand its product portfolio.”

IIG manufactures a wide range of insulation products for use in industrial, commercial and fireproofing applications and offers a unique “good, better, best” portfolio of high-temperature insulation, ranging from mineral wool to perlite to calcium silicate. Each product is designed to meet even the most demanding applications.





“With our increased investment in IIG, JM will be able to offer the most complete line of mechanical insulation solutions to a broader commercial and industrial customer base,” said Dave Skelly, director of sales for JM’s Performance Materials business. “We look forward to continuing IIG’s tradition of superior product performance and customer service.”

JM does not plan to significantly change the operations at IIG. Existing IIG plants located in Brunswick, Ga.; Grambling, La.; Fruita, Colo.; Phenix City, Ala.; and Houston, Texas are a key part of JM’s future commercial and industrial strategy. IIG Chairman and Chief Executive Philippe Delouvrier will remain involved with the company in an advisory role.

“IIG is pleased to join the Johns Manville and Berkshire Hathaway families,” said Delouvrier. “This next chapter in IIG history sets us up for continued success with greater opportunity for growth in existing and new markets.”

“Philippe Delouvrier and his team have made IIG a recognized leader in industrial insulation,” said Fred Stephan, vice president and general manager of JM’s Insulation Systems business. “We’re delighted Philippe will remain involved with the business as we work to build on the success his team has established.”
