The article is devoted to the description of studies of air permeability of modern mineral wool products made of glass and stone fibers. The experimental setup and the course of testing the air permeability of building materials are described. A method for graphically finding the coefficient of air permeability and resistance to air permeability, as well as the characteristics of air permeability used in European regulatory documents: airflow resistance, airflow resistivity and air permeability from the found dependence of the pressure drop on the flow rate air through the sample (according to the method of the domestic standard). The results of finding indicators of air permeability of mineral wool products made of glass and stone fibers are described and analyzed. Filtration indicators for the main types of mineral wool insulation of modern production are found, the dependence of air permeability on density is established. New methodological developments obtained in the course of research are described, which are proposed to be taken into account when developing and updating regulatory documents on this issue.
