What is ROCKWOOL?
Rockwool also known as mineral wool or stone wool is created by spinning molten rock and minerals with steel slag to create a cotton-candy-like wool product. Pressed into rolls and sheets, stone wool creates an incredibly effective insulation with sound-absorbing and fire-resistant properties. It installs like any batt insulation in the wall cavity, but it can be either flexible or rigid, delivering a full scale of solutions to match your needs.
ROCKWOOL products derive their thermal properties from tiny pockets of air trapped within the physical structures of the stone wool. This structure allows the insulation to keep hot air out in hot climates and retain warmth in cold climates.
