Bringing environmentally-sustainable development to Jefferson County

The City of Ranson Jefferson County, West Virginia was one of 50 areas in ten states considered as a location to build our insulation manufacturing facility in the United States. Ranson’s proposal was ultimately selected as our home to build this facility.

The Jefferson County facility, opening Q2 of 2020, will be home to our second stone wool insulation manufacturing plant in the United States, following the facility in Marshall County, Mississippi which opened in 2014.

ROCKWOOL also operates two North American factories in Canada - located in Milton, Ontario and Grand Forks, British Columbia.

The new factory in Ranson (Jefferson County) will serve customers on the eastern seaboard and represent a $150-million investment from ROCKWOOL.

The facility will be constructed on a 130-acre site with a commitment to employ over 140 people (though we expect it will be at least 150) in positions ranging from technicians to management at the state-of-the-art 460,000 square foot facility.

Many locals have told us that the plant will be good for the people who work in town, bringing good jobs with above-average pay, economic development including millions of dollars in tax revenue, and best-in-class environmental performance.
