    Abstract. The international standard used for the determination of residual ions in the production of mineral wool is analyzed. It is noted that this document has some inaccuracies in the terminology, the quality and quantity of the defined elements, the methods of research and the interpretation of the results obtained. A scientific hypothesis, that during the operation of mineral wool in the enclosing structure and its moistening, chemical reactions can occur between the components of the material, leading to its destruction, is formulated. The analysis of chemical reactions is carried out on the basis of the thermodynamic method of studying reactions, which is an estimate for understanding the probability of the process as a whole and makes it possible to determine the preference of reactions, as well as the stability of the resulting compounds in solutions, their energy potential and the direction of the processes. The Gibbs-Helmholtz equation makes it possible to estimate the flow of a chemical process by the isobaric-isothermal potential. On the basis on the analysis performed, it is concluded that it is possible to develop a method for calculating the durability of the mineral wool operation in the enclosing structure.
    Key words: mineral wool, enclosing structures, durability, chemical corrosion, residual ions.
