Mineral Wool Insulation

Thermal conductivity - Temperature and k-values

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.

Relationship between temperature and thermal conductivity is indicated in the diagram below:
