Founded as a family business more than 80 years ago, today ROCKWOOL is the world’s leading stone wool manufacturer producing products made from stone, one of the world’s most abundant natural resources to help address many of the challenges in modern society such as urbanization, fire safety and climate change.

In 1988 we opened our first factory in North America, located in Milton, Ontario, Canada, and since then have setup manufacturing operations in Grand Forks, British Columbia, Canada; Byhalia, Mississippi; and Ranson, West Virginia. We manufacturer and supply a full range of insulation products specifically designed for the applications they serve including exterior walls, below grade and under slab, firestopping, attics, flat roofing, floors and ceilings and interior partition walls.

Why Stone Wool?

In its manufactured state, stone wool delivers unique benefits as an insulation solution. In part due to its non-directional fiber orientation, stone wool also exhibits unique benefits which have come to be known as the 
7 strengths of stone:

  1. Fire resistance

  2. Thermal performance

  3. Acoustic capabilities

  4. Durability

  5. Aesthetics

  6. Water repellence

  7. Circularity

By applying these 7 strengths to everything we do, we passionately believe that we can address some of the biggest challenges facing our world. We’re sure that there are even more strengths of stone to be discovered, and when we discover them, we’ll turn those strengths into new products that improve the quality of life of everyone who comes into contact with them. That’s why these 7 strengths lie at the heart of every ROCKWOOL product.
