History

In 1984, American Rockwool™ began construction of its main plant in central Texas, approximately 60 miles north of Austin. Over the years, the company grew through various partnerships and ownership changes. In 1998, after joining forces with Thermafiber, the company expanded to operate five plants. The company then went through two more transitions, and finally reestablished to its current form as American Rockwool Manufacturing, LLC in 2016. Throughout these changes, the company has maintained its commitment to producing quality insulation products from its Texas facility.
