ROCKWOOL is preparing to begin construction on a \$175 million stone wool insulation manufacturing facility at Wallula Gap, with work expected to kick off later this year, as reported by Ty Beaver of the Tri-City Area Journal of Business.

The company is continuing site grading while it finalizes the selection of a general contractor, according to Paul Espinosa, ROCKWOOOL’s public affairs director.

“We’re hopeful we can begin construction in the third quarter of this year,” Espinosa said.

Even without a general contractor in place, the company says local construction workers will play a major role in the project. PCL Construction, ROCKWOOL’s owner representative, has hosted informational sessions and individual meetings with contractors across the Tri-Cities and Walla Walla. Strong turnout could lead to additional sessions, either in-person or virtual.

“Our goal is to utilize as many local contractors from the Tri-Cities and Walla Walla as possible,” Espinosa said.

A year ago, ROCKWOOL North America finalized the purchase of 250 acres at the Port of Walla Walla’s Wallula Gap Business Park for $8.75 million. The company has since held community open houses to answer questions and address concerns.

Construction of the plant is expected to take two years, supporting more than 600 temporary jobs. Once complete, the facility will employ 125 full-time workers, with hiring focused locally.

Espinosa said the company expects to hire a director of operations this year to build out the management team and prepare for the broader workforce recruitment.
