Jackson, Miss. (Feb. 19, 2025) – ROCKWOOL is expanding its operations in Marshall County. The project represents a corporate investment of more than $100 million and will create approximately 30 new jobs.
ROCKWOOL, the world’s leading manufacturer of environmentally friendly stone wool insulation, has been operating in North America for over 35 years. The company’s Marshall County facility, which has been in operation since 2014, produces a range of residential, commercial, industrial and roofing stone wool insulation.
The expansion includes the addition of a new production line that will manufacture products with ROCKWOOL’s proprietary water repellency and corrosion-resistant technologies, named WR-TechTM and CR-TechTM, respectively. The Marshall County location was chosen to enable ROCKWOOL to better meet demand in the Southern U.S.
Mississippi Development Authority is providing assistance through the Mississippi Flexible Tax Incentive, or MFLEX, program. Tennessee Valley Authority assisting with the project, as well.
ROCKWOOL’s new production line is slated to become operational in 2027.
