What is stone wool insulation?

Stone wool insulation 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.
