Rock Wool Insulation

Rock wool is mainly made of volcanic rock, typically basalt and/or dolomite. An increasing proportion is composed of recycled materials made from slag, and a waste product made from blast furnaces.

Rock Wool Main Usage

  • Thermal insulation
  • Fire resistance
  • High temperature applications
  • Acoustic insulation
  • High compressive strength applications
