Corporate Social Responsibility (CSR)

At ROCKWOOL, corporate social responsibility is an integral part of who we are. Our facility in Ranson, WV is part of an organization where corporate social responsibility starts at the top and involves everyone. While our products help improve people’s living conditions by giving them thermal and acoustic comfort as well as increased fire resilience, we also have a continued focus on our social responsibility

We aim to be a responsible corporate citizen within each of our local communities and the global environment. This is a commitment that began at ROCKWOOL in the 1950s, well before corporate social responsibility became fashionable. Today, this commitment is at the heart of who we are and our values as an organization.

Examples of our corporate social responsibility initiatives in Jefferson County range from supporting Jefferson County Community Ministries, to donating to Kidz Power Pacs, and a partnership with both the Jefferson County Chamber of Commerce and the Jefferson County Fire and Rescue Association.

Should a strong social conscience be an important part of what you look for in an organization then why not think about a career with ROCKWOOL? Corporate responsibility is in our DNA. To learn more, download our Corporate Social Responsibility Fact Sheet
