ROCKWOOL

ROCKWOOL manufactures stone wool insulation, produced by melting basalt rock at extremely high temperatures and spinning it into wool fibers. Founded in 1937 as a Danish family business, the group employs more than 12,000 people and operates in 40 countries, making it the world's largest producer of stone wool insulation. Its products are used across residential and commercial construction, industrial applications, marine vessels and offshore platforms.

The company's technical work spans material science and mineral fiber production, thermal insulation, fire resistance, acoustics and sound absorption, and moisture management. Beyond building insulation, ROCKWOOL also produces stone wool-based growing media for horticulture. The stated purpose of the business is to release the natural power of stone to enrich modern living, drawing on basalt as one of the world's most abundant natural resources.

Products are positioned to support safer, more sustainable and more durable built environments, and the company describes a long-term orientation toward impact across generations. With more than 85 years in operation, ROCKWOOL combines established manufacturing processes with ongoing innovation in stone wool applications.
