Abstract: In the market of building materials production of mineral wool hoard is presented particularly by the wares, made of glass fiber or slag wool with use of organic binding, which don’t meet modern requirements on ecological and fire safety. Therefore an actual problem is creation heat-insulated rigid and semi fixed plates with the operational properties, allowing to use them in industrial and civil building without causing damage to human health and environment, also capable to work at temperatures to 700 ºC and at the same time not to be exposed to thermal destruction. Low heat-resistance of known heat-insulated wares is explained by use of polymeric pitches as a binding component, which collapse at high temperature. In this work for heat-resistance increase were used salt solutions, capable to provide the physical coherence of the fibers which is strengthened by chemical cooperation of used salts with a surface of mineral fibers. To prevent a corrosion of fibers was used the basalt ultra thin fiber which was impregnated with a solution of water-soluble salt on the basis of aluminum sulfate. Wares produced on the basis of a basalt fiber simultaneously were exposed to treatment by waterproof mixture on a silicone basis that allowed to give them water resistance. Received heat-insulated material can be used for manufacture of rigid and semi fixed products of in-creased strength, low heat conductivity and high durability.
