The materials and processes used to produce ROCKWOOL stone wool are environmentally responsible. ROCKWOOL products are created from natural volcanic rock and contain up to 40% recycled content in the form of slag from steel production.This has a large influence on the life cycle environmental impacts of the finished insulation project.

Blowing agents are not needed during stone wool manufacturing, so the insulation results in less harmful emissions as compared to other insulation types. This results in better human health and environmental outcomes, including lower green house gas emissions. Stone wool products can assist builders and designers in achieving a wide range of sustainability certifications or goals when used in mid-rise wood construction.
