Johns Manville (JM), a global building and specialty products manufacturer and a Berkshire Hathaway company, announced today a new Climate Pro® blowing wool production line will be built in Winder, GA. The announcement coincided with the start of the NAHB International Builders’ Show (IBS) in Las Vegas.
“Climate Pro® insulation continues to see strong growth and demand in the market,” said Bob Wamboldt, President and CEO of Johns Manville. “This new production line in Winder will help JM meet our customers’ growing demand for blowing wool.”
Construction is expected to start early next year, and the new production line will be operational in mid-2027. When this project is complete, JM will employ more than 350 people in Winder.
“The location of this production line will provide JM easy access to many of the East Coast and Central U.S. markets,” said Greg Clarke, President of JM’s Insulation Systems business. “Climate Pro® is in high demand, and having more capacity in the Southeast will allow JM to provide excellent service to our customers.”
Climate Pro® blown-in fiberglass insulation fills hard-to-reach cavities and corners while offering consistent coverage, resulting in a more comfortable, energy-efficient home. It can be quickly installed by professionals in attics and net and blow systems, among other applications.
The new production line is a significant investment in the Winder community from which JM will hire operators, maintenance technicians and warehouse employees. JM offers competitive hourly rates and training opportunities to learn new roles, develop new skills and build careers.
