Mineral Wool Insulation

Thermal conductivity - k-values - vs. temperature.

Mineral wool is made from molten glass, stone or slag that is spun into a fiber-like structure. Inorganic rock or slag are the main components (typically 98%) of stone wool. The remaining 2% organic content is generally a thermosetting resin binder (an adhesive) and a little oil.

Mineral wool thermal conductivity vs. temperature are indicated in the charts below:

Mineral wool - Thermal Conductivity - Metric Units
