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.
The relationship between temperature and thermal conductivity is indicated in the diagram below:
- T(oC) = 5/9[T(oF) - 32]
