Who we are

ROCKWOOL, founded in Denmark in 1937, is the world’s leading manufacturer of environmentally-friendly stone wool insulation. Our insulation is used in a range of construction industry applications, including interior and exterior walls, floors, roofs and attics, as well as industrial and original equipment manufacturers (OEM).

Responsible environmental stewardship has been one of our core values for more than 80 years and we continually strive to do better in terms of reducing the environmental impact of our manufacturing activities. We do this by investing in state-of-the-art technology in our factories while at the same time, upholding an unbreakable commitment to meeting and exceeding the environmental protection standards set by governments and regulators wherever we operate globally.

Natural and abundant basalt stone is our core raw material and makes up around 97 percent of our insulation products. We have been making stone wool products since our founding, and today we deliver specialized solutions for a variety of sectors including buildings, marine and offshore construction.

Stone wool, and the products we make with it, play an increasingly significant role in addressing two of the most far-reaching megatrends influencing virtually every aspect of modern society – urbanization and climate change.

While our organization continues to evolve, we remain committed to our purpose – to release the natural power of stone to enrich modern living. 

Our products help combat climate change, leading to more sustainable building practices. And it is through our philanthropy and corporate citizenship efforts, which remain an integral part of our identity as well as the job security and stability we bring to our workforce, that we’re focused on strengthening the communities of which we are a part.

A brief history of ROCKWOOL Group

Founded as a family business more than 80 years ago, today our organization is headquartered in Denmark and is listed on the Copenhagen stock exchange. 

From our first stone wool production in 1937 to the extensive range of solutions we supply today, ROCKWOOL continues to evolve. We are proud of the fact that ROCKWOOL continues to operate with a consistent track record of safeguarding the safety, health, and wellbeing of citizens in the communities living by the 45 facilities in 20 countries where we operate today. 

Stone is our core raw material and the bedrock on which our business is based. Our insulation is comprised of basalt rock and recycled slag, and is developed through an eight-step process that begins with raw materials and goes through to the end product that’s packaged and shipped to customers across North America.

ROCKWOOL company history and timeline of events across North America and the world.

History of the ROCKWOOL organization from its founding to the projected 2020 opening of the factory in Ranson.

ROCKWOOL in North America

We opened our first factory in North America in Milton, Ontario, Canada in 1988. Since then we have started operations in additional facilities in Grand Forks, British Columbia, as well as the opening of our first facility in the United States in 2014 located in Byhalia, a small town within Marshall County, Mississippi. 

Our stone wool is used in a wide range of applications including building insulation; industrial and technical insulation for the process industry, marine and offshore business; customized solutions for industrial applications; wall and facade systems; acoustic ceilings; horticultural substrates; engineered fiber solutions; noise and vibration control; and urban flood control. 

The new factory in Ranson will add to ROCKWOOL Group’s already strong presence in North America. Production in West Virginia will increase our total capacity to meet customer demand, and we are proud to be bringing 150 manufacturing jobs in addition to becoming a positive and contributing member of the county by investing in the community. 

Building our North American presence since 1988, next investment is $150 million facility or factory in Ranson, West Virginia.

Our history of partnerships with fire safety associations

Our insulation works to contain fire and prevent it from spreading through the interior or on the exterior of a building. When seconds count this can provide the people inside the building more time to exit safely and firefighters more time to extinguish the fire.  At the same time, our insulation also does not contribute to the emissions of significant quantities of toxic smoke.

For us, the dedication to fire safety goes well beyond our products as an active promoter and participant in the annual Fire Prevention Week activities. ROCKWOOL advocates for fire safety and advancing regulations in building and fire codes, as well as improving testing standards.

In 2017, our expertise as leaders in fire-resilient and non-combustible building materials was frequently called upon by governments and building companies across North America who sought to better understand best practices in construction.

We collaborate with numerous fire safety associations and councils including the National Fire Protection Association (NFPA), Fire Safe North America (FSNA), and the National Association of State Fire Marshals (NASFM). These networks help advance fire safety provisions in building code development processes and are contributing to the development of increased fire test standards.

Partnerships in fire safety

We work with fire associations and councils to ensure building codes, laws, regulations and practices promote strong methods of fire safety.

Fire safety is at the core of what we do as a company

Through our efforts both in product development and partnerships with fire-related organizations, we are helping to create safer homes and buildings for people in communities around the country, including right here in Jefferson County.

We as an organization are passionate about fire safety and we work at improving it every day. The future of buildings is going to be at a much higher level of safety and quality than we’ve come to expect today and we’re at the forefront of making that happen.

Seven strengths of stone

Stone wool is a versatile material and forms the basis of our business.

ROCKWOOL Group has maintained its position in the market over decades because we’ve had one single-minded purpose: unlocking the strengths of stone to enrich modern living. The world’s most abundant resource can be engineered to create uniquely useful and exciting solutions for the world. And it all starts with what all ROCKWOOL products are made of: stone wool.

Click on any of the titles below to learn about the seven strength of stone wool.

  1. Fire Resilience – can withstand temperatures up to 2100F, works to contain a fire and prevent its spread, making homes and buildings safer for occupants.
  2. Thermal Properties – helps save energy and reduces heating and cooling needs because a good indoor climate is essential to health and wellbeing.
  3. Acoustic Capabilities – helps control the acoustic environment with protection from unwanted noise, increasing occupant comfort.
  4. Water Properties – can be engineered to absorb or repel water while still being vapor permeable.
  5. Durability/Robustness – increase the longevity of performance and future-proof your building to reduce maintenance costs.
  6. Aesthetics – gives you the freedom to design aesthetic environments to ensure occupant comfort and motivation.
  7. Circularity – as one of the most abundant resources on the planet, the stone we use in production can be infinitely recycled.

While our products usually go unnoticed due to their placement in construction, their silent, often-hidden existence can make people’s lives measurably more comfortable and enjoyable. These are seven reasons why we believe the world’s most abundant resource can be engineered to create innovative solutions for modern living.
