Two mutually exclusive properties of building materials, such as low thermal conductivity and high strength, are com-bined in thermal insulation materials designed for enclosing structures. Currently, much attention is being paid to the ma-terials with industrial waste utilization and low production costs. The aim of the study was to develop a heat-insulating composite material based on porous fluoroanhydrite binder with dispersed reinforcement modified with a hydroactive poly-urethane composition with improved vapor and gas permeability. This scientific study provides the development of a ther-mal insulation material with the simultaneous utilization of two industrial wastes - fluoroanhydrite (waste from the pro-duction of hydrofluoric acid and waste from the production of ultrathin basalt fiber). It is noted that the combination of these two wastes during the porization of the fluoroanhydrite composition with hydrogen peroxide makes it possible to cre-ate a material with a thermal conductivity of 0.114 W/m·°C and average density of 550 kg/m3. The modification of the po-rous composition with hydroactive two-component polyurethane provides the material with increased porosity and water resistance. Vapor and gas permeability is ensured, the pore structure is stabilized due to the dispersed reinforcement of the pore walls with basalt fiber production waste, and the use of aluminum powder for pores formation is eliminated. The developed composition makes it possible to reduce the cost of producing, while simultaneously solving the problems of recy-cling fluoroanhydrite and basalt fiber production waste.
