ROCKWOOL has signed an agreement to acquire 250 acres in Walla Walla County, Washington, with the intention to build a state-of-the-art stone wool insulation manufacturing facility featuring proprietary electric melting technology.

The property is located in the Wallula Gap Business Park, a 1,280-acre site zoned for heavy and mixed industrial use. The site is the largest of nine business parks managed by the Port of Walla Walla.   

No construction timeline has been released for the new facility, which would be ROCKWOOL’s fifth North American manufacturing facility and would support growing demand for the company’s products in the western United States.

“ROCKWOOL has operated in North America for more than 30 years. We are excited to take this first step toward establishing ourselves in the Mid-Columbia region and growing our stone wool production capacity to better serve customers in the western United States,” said Rory Moss, President of ROCKWOOL North America. “We look forward to engaging with the local communities and sharing more as plans develop.”

A ROCKWOOL facility in Wallula would represent a $175 million local investment, creating more than 670 jobs over the course of construction. Once operational, the facility would create 125 direct new jobs earning $8.6 million and generate $2.4 million in state and local taxes.

About ROCKWOOL

ROCKWOOL's stone wool is manufactured from volcanic rock, creating a versatile and non-combustible insulation material with a wide-range of uses.
 
It can be engineered to repel or retain water, depending on its use case — whether that's lining the walls of homes to keep them warm and dry or for use in horticultural applications like growing vegetables or flowers.
 
Those same properties make stone wool an ideal insulator for either extremely dry or damp climates, increasing a building's durability by regulating its moisture content and making it more energy efficient.
 
The stone wool building insulation ROCKWOOL sold in 2023 will over its lifetime save 100 times the energy consumed during its production.
