Hello Jefferson County

ROCKWOOL's newest North American facility

Proud to be in West Virginia

We are continually updating this website and associated documents with the latest information

During the past year, we’ve visited and explored the Panhandle. The welcome we’ve received has been inspiring. It’s become obvious – selecting West Virginia as our new home was the perfect choice.

ROCKWOOL is the world’s largest stone wool insulation manufacturer, and we’re proud to become part of this community.

The ROCKWOOL family is thrilled to build a brand-new, state-of-the-art facility in Ranson. It’s a $150 million investment, and it will expand our ability to meet the growing needs of our customers.

But it’s not just an investment in ROCKWOOL – it’s an investment in this community. Once we’re fully operational, the facility will employ about 150 folks from this region. That’s 150 new jobs. That’s a boost for the local economy. And it’s incredibly rewarding. 

We support local charities. 

Our insulation products may foster comfort and safety for buildings and people, but it’s our commitment to our communities that builds the strongest foundations.

Supporting causes that make a difference in our community is important to us.

ROCKWOOL recently sponsored the 8th annual Christmas for Charities, helping the Rotary Club of Charles Town give thousands of dollars to local charities. We’ve also supported the Ranson Tree Lighting Ceremony, which included the Fire Truck Train for kids.

And we are just getting started. 

We believe in protecting  the environment. 

ROCKWOOL’s products are environmentally sound, made with natural rock and recycled slag. Any production waste we create in our facilities is recycled – with no waste going to the landfill.

Recycling and waste reduction are vital pieces of our environmental policies, which also include reusing storm water in our manufacturing process, using the heat from our process to help heat the factory and warehouse, using motion sensor lighting, recycling all pallets and a no idling policy.

Our production line is fitted with state-of-the-art technologies that provide the most effective controls on plant emissions. While we are well within the EPA’s stringent guidelines, we are proud to consistently surpass air quality standards.

A new chapter in Ranson

Just last year, we were known as ROXUL, and our products had always contributed to the energy efficiency of spaces. As of January 1, we are doing business as ROCKWOOL, and that legacy will continue. With the world’s energy consumption expected to rise 50% by 2050, we can address that trend with more sustainable solutions. It’s a bold leap forward and a major milestone in our 80-year history. Ranson is an important part of our future.

ROCKWOOL will continue to be the world’s leader in stone wool solutions. We will continue to deliver superior quality and performance. Our vision remains creating value for our customers as they address the challenges of modern living. Our commitment to delivering product solutions, innovation, education and market growth to our customers will be just as strong.

With the help of this community, we’ll strive to enrich the lives of those around us.

West Virginia Frequently Asked Questions

Plant Expansion


ROCKWOOL International , the parent company of ROCKWOOL (ROXUL USA Inc. ROXUL USA), has confirmed plans to build a 2nd USA based manufacturing facility in  the City of Ranson , Jefferson County, West Virginia

What is the size of the new ROCKWOOL West Virginia facility?

The Facility will be approximately 460,000 square feet, and represents an investment of over $150 Million US Dollars   130 acres purchased.

What types of stone wool products will you be manufacturing in West Virginia?

The facility will manufacture our full line of residential, commercial, industrial and roof board products.  All pipe production remains in Grand Forks British Columbia

When did you announce the new stone wool insulation facility in West Virginia?

The announcement was made by ROCKWOOL International on  July 6th, 2017

How many people will you be employing in West Virginia?

Once completed the new facility will employ 150 with positions ranging from management team to production line. Check out open positions here.

When will you start building?

Site preparation will begin October 2017, full construction is expected in the spring of 2018 and production start expected first quarter of 2020

Has ROCKWOOL communicated with local and state agencies regarding its permits for the Ranson, West Virginia facility?

ROCKWOOL is working closely with the State of West Virginia, Jefferson County and local authorities to ensure the project is designed and constructed to be in full compliance with building code and environmental standards. We value feedback and input from a variety of groups, organizations and representatives in the region. We continue to be transparent throughout this process and address any concerns to be the best neighbor we can be. 

Has the West Virginia Department of Environmental Protection (WV DEP) asked ROCKWOOL to do any self-reporting of the company's compliance with the permits requirements?

Yes. The type of permit ROCKWOOL was granted requires reporting through continuous emission monitoring systems once the plant begins operating. The system will track hours and production as well as conduct stack testing. 

When will this facility be operational and how many long-term jobs will be created?

Production is expected to start in the second quarter of 2020, with approximately 150 people expected to be hired in positions ranging from production line to management. 

If local citizens are concerned about emissions from ROCKWOOL, how do you address these concerns throughout the construction phase and during operations?

ROCKWOOL is committed to protecting the environment. Our products are natural, made from basalt rock. Our controlled emissions from manufacturing are well within the stringent limits set by the WV DEP. Our goal is to ensure this commitment is maintained throughout the construction process and in all areas of the production facility. Our production line will be fitted with state-of-the-art technologies to control emissions and to ensure they are in full compliance with the air quality and other standards. ROCKWOOL is committed to continuing work with the WV DEP and other authorities throughout this process. 

Why was a different name used for this project?

Most major corporate transactions, such as mergers, acquisitions and divestitures utilize code names because publicly traded companies like ROCKWOOL must protect this kind of information until it is approved by its board and publicly announced. So, in other words, this is a matter of procedure and in no way an attempt to hide from the public. Some of the preliminary regulatory processes needed to happen before Roxul USA Inc., now ROCKWOOL, could purchase the land. In fact, the project was sometimes referred to as “Shuttle” or the “Granny Smith Lane” project to protect our competitive, proprietary information. Other entities, such as Jefferson Orchards, filed some of the notices and applications because they were the legal owners of the land at the time. 

Has ROCKWOOL been in compliance during the air permitting process?

Yes. We’ve fully demonstrated compliance throughout the process, as outlined in the Air Permit Engineering Evaluation drafted by the WV DEP, and we will continue to work together with the appropriate regulatory agencies to do everything necessary for compliance. We are committed to operating within very stringent guidelines. ROCKWOOL has conducted a full Best Available 

Control Technologies (BACT) assessment, which provides a detailed analysis of available technologies suitable for the project. Our facility will leverage advanced control, capture and measurement technologies. 

How have you communicated the project to the public?

Both ROCKWOOL and the WV DEP placed legal ads about the project in local newspapers, as required by law. The company also reached out to government organizations at the state and local level and presented information about the expansion during various events and in front of various groups. In addition, ROCKWOOL introduced itself via direct mailings to residents in Ranson and Jefferson County and has reached out to media several times throughout the region to discuss the project. Throughout the process, ROCKWOOL has been, and will continue to be, transparent and open. 

Will the facility result in an increase in truck traffic?

Like at our other facilities, we do not expect our truck traffic to be a nuisance to our neighbors or the community. We will work with local transportation officials to best manage this process. 

How much water will be used at the Ranson, West Virginia facility per day?

We estimate using between 100,000 and 125,000 gallons per day, with the majority of that evaporating during our process. Between about 13,000 and 26,000 gallons per day will be discharged to the municipal wastewater treatment plant and it will be generated from a Reverse Osmosis Treatment process to remove additives from the provided city water. 

Will you utilize coal ash ponds?

There are no coal ash ponds at this facility because coal ash is not being generated at this facility. The Ranson facility will utilize storm water settling ponds as a collection basin to be reused in the manufacturing process. There is a small portion of solid material that is generated during manufacturing that will be re-cycled into the manufacturing process. 

What kinds of emissions can be expected?

The State of West Virginia has ensured that facilities such as ROCKWOOL operate in a manner that is safe by adopting the Federal Clean Air Act and all its requirements, which include limits on emissions. Permitting under the Federal Clean Air Act is handled by the WV DEP. 

ROCKWOOL obtained its Clean Air permit in April 2018 after meeting all requirements, including the submission of emissions data and identifying the best achievable control technologies (BACT) that will be used to keep emissions below federal and state limits. In addition, 180 days after start -up ROCKWOOL will have to conduct testing to demonstrate compliance on additional emissions (Phenol, Formaldehyde, Methanol) regulated by US EPA beginning in 2015. 

Again, though monitoring emissions is a standard procedure at ROCKWOOL, it also is required by both WV DEP and US EPA. ROCKWOOL’s new line at the Ranson facility will be fitted with state-of-the-art technologies to provide the most effective controls on our emissions and to ensure they meet all environmental air quality standards.  

How many stacks will be built at the facility?

Two primary stacks currently are permitted at 65 meters, or 213 feet each. Smaller stacks also are permitted. Various stacks are required to capture emissions at different points along the manufacturing process. Our stack heights are determined largely by what is needed to meet the WV DEP requirements and regulations for aviation safety. Stack heights are determined to meet dispersion requirements to pass air modelling, and though higher stacks are more expensive, they’re also better for the environment. ROCKWOOL is using state-of-the-art equipment to ensure emissions meet all applicable regulations at the Ranson facility. 

If I have questions about this project, who do I contact?

ROCKWOOL is committed to providing factual information to the public about its Ranson, West Virginia facility. For more information, please contact Leslie McLaren at leslie.mclaren@ROCKWOOL.com. You can also visit www.ROCKWOOL.com. 

Why are you building another facility in the US?

Rising demand for our stone wool solutions in the US market place was the primary catalyst behind the decision for another US factory. It will help us better serve our customer’s needs as the new factory is close to major population centres in the North eastern and, Mid-Atlantic. 

Tell us about the design and construction as it relates to the environment

Your product is known for being a fire barrier, tell us about this

ROCKWOOL insulation is non-combustible, and provides a fire barrier. It can withstand temperatures up to 2,150 F. Our insulation is a key component in fire-resilient buildings as its stone wool fibres are inherently non-combustible and can resist temperatures up to 2,150 F. This is crucial to containing a fire locally and securing that a fire in a building will not become a building on fire.  And with minimal organic content, ROCKWOOL insulation will not produce any significant toxic smoke. 

Where have your products been used?

ROCKWOOL products have been used in many prestigious buildings and facilities in the USA for example:  Cornell Tech (NY City) the largest passive house in the world, Manhattan Courtyard Marriott, Minnesota Vikings Stadium, Empire State Building, Fort Bliss Army Hospital.

Environment and Sustainability

What is your stone wool insulation made of?

ROCKWOOL products are produced from a combination of natural basalt rock and recycled slag. These simple ingredients are melted, spun into a fiber and cured to product insulation of the highest quality that is better for the environment. 

What role can insulation play in building energy usage?

Buildings account for 40% of the energy use, and 2/3 of that is used for heating and cooling. Insulation can play a key role in reducing heating and cooling costs, reduce greenhouse gas emissions, and provide a more comfortable work/living environment.

Your insulation can resist fire. Tell us about that

Stone wool can resist temperatures up to 2,150F. It can help contain fires, and avoid significant toxic smoke. This gives more time for those inside a building to escape, and more time for firefighters to arrive, and reduce the amount of damage.

Your insulation products have been tied to healthy living. Why?

Stone wool insulation provides is an important component of comfortable and healthy living. As well as it’s thermal properties, it provides sound control – blocking unwanted noise through wall and floor assemblies, in homes, offices, schools hospitals etc.,
